Compliance is a Strategy for Success

Compliance is a Strategy for Success

By | Network Security | No Comments

As the nature of compliance grows increasingly complex, it becomes more difficult for companies to understand what applies to their business and how to build and implement protocols. Furthermore, as cyber threats grow exponentially, companies are facing problems like potential governmental fines and financial theft, breach of sensitive data and loss of clientele. Author of the bestseller “Security Risk Assessment Handbook” and cybersecurity expert, Douglas Landoll, recently stated that, “Non-compliance with information security regulations remains one of the top mistakes made by companies in their current data security approach.” Don’t say we didn’t warn you.

We have mapped out the four steps that you should follow for your business to become compliant and ready to counter growing cyber instability.

 Step 1 – The tight relationship between compliance and cyber security

Once upon a time, organizing cyber defense fell under the domain of the IT guys, but over time, the cybersecurity tent has broadened to encompass CCOs and CISOs. According to a recent survey conducted by BAE Systems, the majority of IT staff want C-Suites at the front and center of cybersecurity decision making. One can have the best technology on the market, but without a clear process and defined roles, it will be exceedingly difficult to prevent attacks.

The New England Chief Audit Executives group conducted a roundtable discussion, which concluded that without a comprehensive strategy of processes in place, your tools are more or less useless. Simply put, having great technology without a compliance program will likely result in failure. We saw this very clearly in the Yahoo hacks between 2013-2015, which compromised one billion accounts and caused the company tremendous damage both financially and to its reputation.

The creation of an efficient cybersecurity compliance program involves many factors like auditing, understanding all relevant stakeholders, understanding country specific regulatory laws and the adoption of the right security technology to meet these needs.

Step 2 – Know your country

Cybersecurity regulations can vary from country to country or region to region. For instance, the EU is 12 months away from implementing its General Data Protection Regulation (GDPR), which covers a wide range of security issues like data security, management, and transparency. It is worth noting that fines can reach up to 20 million euros. This past October at the UK CISO Summit, participants discussed the implications of the new regulations, in that companies will be forced to devise new approaches to storing, protecting, monitoring data, and staff and resources involved in order to be in compliance with GDPR.

In fact, in March, Democrats in the United States Congress began demanding that the Federal Communications Commission (FCC) create new regulations for cybersecurity for cellular networks. However, the FCC claims that cybersecurity is not under its purview and thus they will not act on the issue. This comes on the heels of an executive order by President Trump calling for an extensive review of US cyber vulnerabilities and capabilities. Considering that the United States is a gigantic bureaucratic web, and executive orders are usually short lived, it will take time for the US to get its act together. Other countries like Japan and Brazil are also in the process of developing their own regulations for transparency, consistent access and authentication for various types of data. Countries around the world are recognizing the importance of digital compliance and standards and are making steps toward ensuring the safety of their citizens’ and businesses’ data.

Step 3 – Timelines and shareholders

When first building your compliance structure, start with timelines. Governmental agencies often put time constraints on companies to come into compliance. For example, the new standards for the NY State Department of Financial Services. The agency is giving companies until March 1, 2018 to provide a risk assessment report, but an additional six months to implement the programs that result from the report’s findings. Business and organizations should push lawmakers to prevent a situation where the global marketplace becomes fragmented by regulations, due to rapidly changing technologies and threats. This would lead to the crippling of competition and innovation and subsequent the strengthening of cybercrime.

It is furthermore important that all stakeholders, including directors, management, security staff, and vendor partners be connected via a shared platform. This will allow them to collaborate within a defined framework. The platform should incorporate governmental regulations like FINRA, HIPAA, FERPA to better connect directors with technological experts, track progress or changes, and allow for effective oversight. However, it is becoming increasingly clear that the bulk of the responsibility for heavy decision making is shifting from IT personnel to the board of directors. This is a natural response to increased demands from organizations like the SEC and FTC. However, it is imperative for communication between the board and all stakeholders to remain strong. It should be noted that compliance is critical in order to prevent theft and mishaps similar to what happened at Bangladesh Central Bank.

Step 4 – Compliance starts at the CORE

Once your organization fully understands the regulatory policies it is subject to, it must then learn how to see and profile all network devices, remediate any security issues and automate actions that have traditionally been conducted manually.

There are four segments to this process:

  • Understanding how mobile, BYOD and IoT devices will affect and transform not only the organization, but the industry and implementing the right processes and tools control them.
  • Tracking any network related device or program in real time via a centrally secured platform providing full and actionable visibility.
  • Addressing cloud security is paramount, because everything today is going through the cloud. It is important to strictly control access to the network and to cloud applications, even based on the geographical locations of users.
  • Ensure that your business is in compliance with governmental regulations like SOX, PCI DSS, HIPPA, FINRA, FISMA, GLBA among others. Strict compliance will provide legitimacy with clients and partners.

Once your organization understands that without full and actionable visibility on the network it will be impossible to control devices or maintain compliance standards, the next step is finding the right tools. Portnox’s advanced system allows network operators to see and control any device, at any time, and from anywhere, making compliance a more straightforward and smooth process. Portnox continues to lead the way with its innovative technology that will allow you to tackle risk challenges in a simple and straightforward manner.

Cyberattacks ≠ Compliance

Cyber Attacks ≠ Compliance

By | Network Security | 421 Comments

In our recent “Cyber Threats Cannot Compete with Strong Compliance” blog, we covered cyberattacks in the financial and retail industries and the importance of visibility, network access and control, and risk management to achieve strong compliance, defend against cyberattacks, and grow a successful and secure business. In this blog, we take a quick look at the attacks that hit government and medical industries, the regulations these verticals face and how to build a strong compliance foundation. A deep dive into each of these verticals can be found in “The Compliance as a Strategy for Business Success eBook”.

The DNC Got Phished

How did Russian hackers gain access to the email correspondences of the Democratic National Convention throughout the recent US election? The answer is by using the oldest trick in the book: phishing emails. In one case, John Podesta, chairman of Hillary Clinton’s campaign received a phishing email, which was in fact correctly identified as such by an aide. The problem was that the aide accidentally made a note calling the email “legitimate” instead of “illegitimate”, leading Podesta to open the email. This single mistake placed over 60,000 highly sensitive emails in the hands of the Kremlin, which went on to distribute the information to websites like WikiLeaks.

Even after the FBI sent a special agent to warn to the DNC of the phishing emails, their IT did not respond to the warnings because computer logs did not reveal any intrusion. Podesta should not have required an aide to manually mark the email as illegitimate. Had the DNC incorporated an agentless solution into their network, they could have automatically monitored, identified, tagged, or blocked a potential attack.

The Dark Web Over the Medical Industry

Since 2010, the number of attacks against healthcare providers has risen by over 125% and risk levels in the industry are now at the highest ever. In fact, just last year, cyber criminals hacked over half a million patient records and began selling them over the Dark Web for profit of approximately $365 per record. That is about one-third more costly than selling stolen financial records – no wonder that this form of theft is growing at a dizzying speed. Part of the big issue is that hospitals, private clinics, vendors and insurance companies all share digital information, which of course creates the perfect conditions for cyber-criminal activity.

There is no doubt that the medical industry is struggling to uphold HIPAA regulations regarding privacy, security and enforcement. As medical connected devices continue to grow, a solution that is scalable across a wide range of institutions is a must. It is crucial that every institution sharing this data implements a solution that enables security teams to have complete visibility of all connected devices in real time, including switches, wireless controllers, VPN gateways, and routers.

A Boardroom, Samsung and the CIA

Among the 7,800 CIA records released via WikiLeaks, it was revealed how the CIA has been taking advantage of devices like Samsung’s smart TVs to spy on people across the United States.  Under the codename “Weeping Angel”, the CIA used malware that makes the television act like a bug and send recordings back to them.

Samsung had already warned within its privacy policy that the voice recordings are uploaded to servers and can be passed on to third parties. However, while it is possible for the user to shut off the microphone completely, the CIA found a simple way to circumvent that. As such, organizations need to check the state of their equipment, whether it be a smartphone, laptop or a TV screen. Any device that can record and has access to the internet is susceptible to hacking. Companies must safeguard their equipment and implement practices like device lock-down, micro-visibility, and risk monitoring.

Whether you run a financial, governmental, retail or healthcare organization, it is essential to see, control and automate your network. Without full network visibility, it is impossible to control devices or maintain compliance standards. The challenge for many is how to maintain a level of security (even large companies struggle to attain compliance) often with limited resources and budgets. Portnox’s advanced technology – available both on-premise and in the cloud – gives security officers and network operators the tools they need to see and control any device, at any time, from any place. With these tools, Portnox makes compliance a more straightforward and smooth process, setting your business up for success.

Cyber Threats Cannot Compete with Strong Compliance

Cyber Threats Cannot Compete with Strong Compliance

By | Network Security | No Comments

2016 saw several high profile cyber-attacks, which resulted in costly breaches and damages to reputable companies and corporations. There have been several discussions in how to effectively preempt such cyber-attacks with solutions ranging from firewalls, endpoint device security, to network access management solutions.

Mindful that many industries maintain tough regulatory standards, companies are now required to implement automated systems to keep up with reporting, while also preventing breaches. The “Compliance as a Strategy for Business Success eBook” covers the key points that need to be considered when trying to achieve security compliance for regulations like SOX, HIPAA, PCI-DSS, FISMA, and GLBA. For instance, any company that stores, processes, or transmits cardholder data, must be PCI-DSS compliant. Compliance includes restricting access by what businesses need to know, creating processes to provide user access to system components, initialization of audit blogs, and more. However, these processes come with significant cyber risk.

If the cyber-assaulted companies had stronger foundations for compliance, they would not have needed to devise new and expensive technologies.

The Importance of Visibility to Achieve Compliance

When Yahoo Got Stuffed

Yahoo is no stranger to breaches. This past year it came to light that nearly 1 billion Yahoo accounts had been compromised between 2013-2015. How did this happen and what could have been done to mitigate or even prevent the hacks all together?

This was a type of mass-scale brute force attack called “cyber stuffing” which took advantage of previously hacked credentials by inserting them into random websites via automation until they found a match. Automation allowed this attack to be conducted quickly and more often than not, completely anonymously. Shuman Ghosemajumder, CTO of Shape Security, found that credential stuffing is successful in 0.1-2% of attempts and considering that many people reuse passwords across a range of websites, it can be damaging. This is especially concerning because as a publicly tradable company Yahoo is subject to SOX compliance, which was designed to protect data integrity via compliance.

If Yahoo had implemented an intelligence engine to provide admins with wider and deeper visibility of their network in real time, they would have better understood the warning signs presented in 2008 by Carnegie Mellon University’s Software Engineering Institute. The institute urged Yahoo to replace their encryption technology, MD5, which was considered cryptographically broken. Despite years of warning before the major hacks of 2013-15, Yahoo never brought the encryption up to date, because they lacked visibility and oversight.

The Ghost of Bangladesh Central Bank

 In February of 2016, $81million disappeared from Bangladesh Central Bank and was subsequently laundered in casinos throughout the Philippines. Cyber criminals used bank employees’ stolen Society for Worldwide Interbank Financial Telecommunication (SWIFT) credentials to send dozens of fake money transfer requests to the NY Federal Reserve, requesting a total of a $1 billion to be transferred to various bank accounts that had been set up a year earlier in Asia. While most the requests were blocked, $81 million was released in four transfers of about $20 million each. So how was the heist pulled off and what could have been done to stop it?

The hackers implanted malware on end-point devices on the bank’s network, which prevented the automatic printing of SWIFT transactions. This undoubtedly, brought the bank into conflict with GLBA, which demands financial institutions to protect data. Both the bank and the Federal Authorities are playing the blame game. The Feds claim they followed protocol which permitted several transfers, while blocking dozens of others. There is no doubt that lack of end-point visibility and virus protection were massive issues here. The theft could have been avoided if both the bank and the Feds had total control over all network infrastructure.

To become security compliant and run the business successfully, companies need visibility on what is happening on the network. In other words, what devices are connected to the network, when they connected, what OS, applications and services they are running, who has access to what data, and proof that mechanisms to secure private data are operational. Without visibility into what is on the network, it’s impossible to control the network and ensure compliance.

Back to the Basics with Your Network Protection

By | Network Security | No Comments

Old-time marathon winner and runner Bill Rodgers once made the comment that, “Every race is totally different.” And if this is true in the relatively predictable world of marathon running, it is even more accurate in the race against cyberterrorism, where – whether we like it or not – each day brings with it unforeseen challenges that threaten the integrity of the network.

The question is how best to approach network protection successfully despite the ongoing development of unexpected threats. The truth is that throughout 2016, we’ve had more than ample opportunity to consider this question. From the involvement of hackers in the U.S. elections to the IoT DDoS attacks of October 21, last year saw some shocking stories of breaches. With all of that behind us, 2017 is not a moment too early to take stock, explore the options – and perhaps, go back to the basics and adopt some old-new security strategies that provide greater visibility, improved resilience, increased automation, and better security.

An Unfortunate Side of “Things”

The distributed infrastructures of today’s networks make businesses more vulnerable to attacks, with IoT and BYOD adding a huge degree of complexity. The threat is simply greater – so much so that, according to Gartner (as quoted on TechCrunch here), the security market is predicted to grow to the whopping size of $120 billion by 2020.
As pointed out in the eBook, The Top 5 Misconception of IoT Network and Device Security, IoT devices represent the weakest link of today’s corporate network. To make matters worse, because most users are unaware of the threat, most devices are not even set up securely. (to learn more, read the eBook preview here.)

Because Seeing is Believing

Part of why IoT and BYOD have changed the situation so drastically is that new devices (both managed and unmanaged) are constantly being connected. Any device connected to the network can potentially function as a gateway into your infrastructure.

It has become all too common for there to be a “disconnect” between the number of devices the average IT administrator thinks is attached to the network, and how many devices are actually there. Shockingly, it is not unusual for the disparity to be as high as 20-30 percent.

In approaching the protection of any network, visibility is key – because you cannot protect what you cannot see.

An Innovative Approach to Today’s Security Challenges

A Next-Gen network visibility and access control management solution such as Portnox CLEAR continues to provide ongoing and comprehensive protection against hackers. With Portnox CLEAR, an organization can be hermetically covered, and IT and CISOs regain the visibility and continuous risk assessment they need.
Portnox CLEAR gives you 100% visibility of all devices, including managed and unmanaged devices. With this comes greater control and security, and the ability to develop new strategies – particularly, segmentation of IoT devices, so that they only access a limited part of the network.

The Need for Speed

Portnox CLEAR handles the complexity of today’s networks through Continuous Risk Analysis (CRA), which provides more flexibility than the approach of a one-time “grant or deny.” CRA is built to provide protection in a reality that involves a broad range of devices as well as “anytime, anywhere” connectivity.
CRA is a response to the need to act fast in the geo-distributed mobile workforce of BYOD and IoT. Replacing the old tactic of periodically scanning, CRA provides a real-time approach to network admission control that allows you to continually assess endpoint risks to the network.

Putting It All in Context

Portnox CLEAR also offers an unprecedented degree of context awareness, monitoring changes in hundreds of parameters and correlating multiple context attributes. This provides an adaptive and more analytic approach to risk determination, and facilitates the development of security assessments that are much more comprehensive – taking into account considerations such as time, network location, user identity, and scenario.
Context awareness is particularly significant to today’s cybersecurity because it facilitates the discovery of anomalies – both as relate to device behavior, and as relate to the status of the network.

100% Visibility and Real-Time Access Control

Portnox CLEAR offers ongoing network visibility and access management control so that you can keep your network safe, with real-time risk assessment that mitigates the cybersecurity threats.
As a cloud-based endpoint security management solution with context-aware security assessment capabilities, Portnox CLEAR is up to the challenge of optimally protecting the security of your network.

Continuous risk assessment of endpoints or a one-time audit?

By | Network Security | No Comments

Are you up to speed with your cybersecurity?

Do you really know, in real-time, who is hooked onto your network? Do you have full control of the entire network and all its components, as well as all the devices that need to connect to it? Are all the users keeping their devices secure and free of ransomware?

In a world of hyper-fast services, cloud computing, a geo-distributed mobile workforce, BYOD, and IoT, it is truly a daunting task to control the network and all its endpoints with a key element of success being speed. Therefore, the only solution for the IT security officer is to adopt a new approach; Continuous Risk Assessment (CRA) is a real-time approach to network admission control, an approach that recognizes the need to speedily and continually assess the endpoint risks to the network.

Your network is only as strong as its weakest security link – therefore CRA calls for constant monitoring of the endpoints. The traditional auditing approach of periodical scanning simply lacks the crucial element of speed, which enables network and security teams to stay ahead of cyber attackers by discovering new risks in real-time, acquiring decision supporting data, reacting to changes and anomalies and delivering protection on a continuous basis.

Avoid the 5 Pitfalls of NAC – Get our Free Whitepaper Today! 

The benefits of Continuous Risk Assessment (CRA)

The National Institute of Standards and Technology (NIST) defines Information Security Continuous Monitoring (ISCM) as:
“Maintaining ongoing awareness of information security, vulnerabilities, and threats to support organizational risk management decisions.”

According to NIST, risk assessment is to be conducted in a frequency that supports a risk-based security decision system and enables adequate protection of the organization’s data.

Furthermore, NIST experts specify that ISCM should be:
“…sufficient to ensure and assure effectiveness of security controls related to systems, networks, and cyberspace, … in accordance with organizational risk tolerance – and within a reporting structure designed to make real-time, data-driven risk management decisions“.

The above recommendations are easier to understand when continuous monitoring is reviewed in light of the major benefits, which a top notch CRA solution should entail. These benefits are:

Proactivity – Real-time CRA must provide organizations with immediate visibility of the security state of the network and all the devices connected to it, reporting their potential vulnerabilities. This enables organizations to address potential issues before they become security breaches. Organizations using CRA are taking a proactive approach to avoiding breaches, instead of investing an ever growing effort in detecting breaches that have already occurred. This approach entails effective management of high-risk devices, proactively preventing future threats.

Updated Context-awareness– The traditional audit approach is based on using pre-defined compliance parameters to determine a risk to the network at the time of the scan/audit. The CRA new approach depends on real-time and continuous update of varied risk factors by:

  • Monitoring changes in hundreds of parameters
  • Analyzing and correlating to multiple context attributes
  • Taking historical records into account

Continuous monitoring brings an analytic and adaptive approach to risk determination. It does so by correlating hundreds of parameters and keeping the security policy updated at all times. Security status analysis is context-aware (time, network location, user identity, and scenario are all considered), identifying anomalies in the network security status and/or in device behavior.

Anywhere, anytime functionality – In a world with no boundaries and a high diversity of endpoint types, CRA must provide capabilities for monitoring devices  in any location, no matter what type they are and what type of data is being transferred, or where they are connecting from.

Continuous monitoring must keep the network secure even if employees take their corporate laptops home or connect their phones from a hotel during a business trip. Alternatively, the network needs to remain secure even when staff connect their personal smartphones at the office. CRA must function on and off the corporate network and remain relevant for all current types of devices and OS’s.

Complete Integration – A silo solution cannot work in today’s complex IT scenarios. Stand-alone vulnerability scanners will be abandoned, simply because they are not an integrated part of the entire network operation.
Continuous monitoring procedures must be integrated into the organization’s network infrastructure.

One approach towards achieving this goal is a tight binding of risk assessment with access scenarios, in particular with the network admission (NAC) solution. In the ideal approach, CRA ultimately becomes a natural and deeply integrated part of admission, starting from device on-boarding and continuing with device authentication and re-validation before permitting access to the network.

Automated Action – The desired solution must offer an actionable, preferably fully-automated processes to already determined risk factors.  A report of problematic issues is only useful when it is also clear what protective actions need to be taken. For example, quarantine of a risky device or an adaptive approach to VPN authentication related to device risk levels. CRA helps assess potential risks, prioritize resolutions and initiate protective actions.

Portnox CLEAR –  on/off premises continuous risk assessment solution

Portnox CLEAR is a cloud-based network access control (NAC) and endpoint security management solution, offering a cohesive approach to Continuous Risk Assessment. As opposed to stand-alone vulnerability scanning tools or NAC solutions with a naïve approach to endpoint stateless posture, Portnox CLEAR delivers ultimate control over users and devices, which can access your network anywhere, anytime. It does this through various access layers, while continuously, pervasively monitoring and understanding endpoint risk in its real-time context.

Portnox CLEAR enables real-time risk assessment of devices – on and off customer premise networks. We know how to take smart actions and proactive access decisions, based on the risk from devices attempting to access your network. Device profiling reports are continuously updated, for complete integration and automation.

With Portnox CLEAR, network and security teams enjoy the full benefits of the CRA approach to network access control. They will  really know, in real-time, who is hooked onto the system; to have full control of the entire network and all its components, as well as all the devices that need to connect to it, knowing they are all compliant with NAC policy.  The answer to the concerns, which opened this post is a resounding YES with the Portnox CLEAR solution to CRA from Portnox.

Your VPN is Only as Strong as Its Least Secure Endpoint

By | Network Security | No Comments

If you are like most companies, your corporate VPN is a critical part of your infrastructure—and it’s getting a heck of a workout. Thirty-seven percent of all workers in the U.S. now telecommute. Even if your workers are in a more traditional office, many of your employees will be traveling at any given moment. You might even have remote offices in other countries. With so many remote workers taking up bandwidth on your VPN, how do you audit their devices?

The concept of BYOD is busily colliding with the concept of VPN. Seventy-four percent of companies now incorporate BYOD policies—and yes, BYOD absolutely makes VPNs less secure. Sure, you have trust in your VPN and some level of safety in knowing only those set-up to use your VPN are actually connecting. As for the devices that your users are using to connect, however, it’s impossible to know if their configuration makes them insecure.

Download: The 802.1x Sting Whitepaper Now!

Let’s face it—once a corporate or BYOD endpoint leaves the security and control of your network, it is no longer available for you to scan, health check, validate or update. You don’t know where it has been, who it’s been with and most importantly how it might have changed. Yet, you welcome it to rejoin your company network at any time from anywhere via your VPN—after all, you trust the user and they have the authorization to use the company VPN, what could go wrong?

A Compromised VPN Could Be a Ticket to Your Worst Nightmare

Here’s a doomsday scenario: you could lose millions of dollars. Not from customer lawsuits (as in the case of most data breaches), or in reputational damage. You could have money stolen from you directly. This was the case when hackers used malware known as the Carberp Trojan to steal over a billion dollars from various banks over a three-year period.

Essentially, the attackers were able to use their malware in order to compromise the computers of trusted bank clerks. This malicious software allowed the attackers to remotely control computers in a manner similar to helpdesk software such as Teamviewer or LogMeIn. Because the clerks’ computers were already logged into the bank’s trusted network, the attackers had no difficulty rooting around and transferring billions of dollars into their own accounts.

You Can’t Trust Users with the Security of Their Own Devices

Did the Carberp attackers have much difficulty compromising administrators at those big banks? They did not—they used simple phishing attacks, which one in every three users will fall for, according to the 2016 Verizon DBIR. Even if you’re relatively confident that your users won’t be fooled, Murphy’s Law will go after you in any way it can.

Maybe your users disabled their firewalls. Maybe while traveling the anti-virus has not been updated. Maybe device encryption was disabled. Any number of things could change at a device level that would make the device a risk to your company. Any of these vulnerabilities leave the endpoint vulnerable to takeover, and could allow attackers to spread malware or intercept communications over your private network.

Choose an Intelligent Gatekeeper for Your VPN

Portnox CLEAR picks up when a device is no longer in the grasp and control of your company network and tools. An easy-to-deploy cloud solution, Portnox CLEAR maintains continuous real-time awareness of a device whether it’s on or off your network. CLEAR is always aware of the current risk posture of a device, and keeps constant tabs on the firewall, antivirus, patch level, and more.

Most importantly, CLEAR is not just aware—it’s active. VPN access is only permitted to devices who have a sufficiently low risk profile, based on the monitoring above. It’s no longer okay for any device that has VPN access to connect—with CLEAR you now have the added security knowing the device connecting is still in compliance. What’s more, CLEAR can prevent lost or stolen devices from accessing the private network by implementing two-factor authentication for VPN connections at no additional cost.

With CLEAR, you can let your devices travel, let them work from home, visit Starbucks, and attend seminars—and let them connect back via your VPN with the security, trust, and awareness Portnox CLEAR provides.

Wireless Guest Network in Less Than 10 Seconds

By | Network Security | No Comments

We’re happy to announce the production readiness of our new and innovative capabilities: a cloud-based Guest Network with a highly customizable CLEAR Captive Portal.

Portnox CLEAR customers who added guest subscription can now offer their corporate visitors, contractors, students and customers Wi-Fi connectivity following less than 10 seconds (!!!) of configuration, without having to install any on-prem component and without compromising the security of the corporate network.

Portnox CLEAR offers the entire infrastructure stack for a guest network as a SaaS service which includes a Cloud RADIUS, a CLEAR Captive Portal web app, and a management system for configuring and monitoring guest network activity. At a single click in the CLEAR Portal, the entire infrastructure is immediately activated for your visitors, BYOD-owners and students who will use a branded, web-browser login to connect to the guest WI-FI. No agents or on-prem components are required, merely a wireless access point and a CLEAR account.

Find out more about Portnox CLEAR

The Portnox CLEAR Captive Portal offers the following authentication methods for accessing the guest WiFi:

1. “Lobby administrator” mode – enables granular and centralized control over who can access your guest network and when. In this mode, the administrator defines the CLEAR Guest Account prior to the guest visit and can control various parameters of this account, including expiration time. CLEAR also provides a special administrative Guest Admin role, which provides only guest management permissions in the CLEAR Portal without any ability to see or change other aspects of Portnox CLEAR configuration.

2. No authentication (disclaimer only) mode – The guest merely needs to acknowledge a disclaimer. The disclaimer (“acceptable use” statement) is customizable; a CLEAR Portal administrator can define both the text and the formatting of the disclaimer.

3. “Sponsored” guest mode – A guest is required to provide a sponsor’s email upon registration in the Captive Portal. Sponsors, usually administrators or people defined as sponsors inside the organization, automically receive an email with a request to Grant or Deny guest access. If access is granted, the guest receives an email with access credentials. This authorization workflow is fully-automated, does not require access to the CLEAR Management system, and requires only email.

The Portnox CLEAR architecture enables you to configure Wireless security and Guest Networks in a way that both fits your corporate needs and requires the lowest investment of administrator time.
