Secure Access Service Edge (SASE)
Cloud-native Network Access Control (NAC) and on-premises NAC systems both serve the essential purpose of securing networks by controlling which devices and users can access network resources. However, they differ significantly in their deployment models, operational flexibilities, and maintenance requirements. Here are some key advantages of cloud-native NAC compared to on-premises NAC:
Scalability: Cloud-native NAC solutions are highly scalable. They can easily accommodate an increase in the number of network devices or changes in network size without the need for additional physical infrastructure. This is particularly beneficial for organizations that experience fluctuating demands or are in growth phases.
Reduced Hardware Dependency: Since the infrastructure and services are hosted in the cloud, there is no need for organizations to invest in or maintain physical servers and other hardware. This not only reduces capital expenditure but also minimizes the space and power requirements associated with on-premises hardware.
Cost Efficiency: Cloud-native solutions typically follow a subscription model, which can be more cost-effective than the capital expenses associated with purchasing, running, and maintaining on-premises hardware and software. This model also typically includes updates and support, reducing the additional costs for IT staff and upgrades.
Maintenance and Updates: Cloud service providers handle the maintenance and updates, ensuring that the NAC solution is always up to date with the latest security patches and functionalities. This offloads a significant burden from internal IT teams and helps in maintaining strong security with less effort.
Ease of Deployment: Deploying cloud-native NAC solutions is generally faster and less complex than setting up an on-premises system. Since the infrastructure is already in place in the cloud, configuring and rolling out services can be done remotely and more swiftly.
Remote Accessibility: Cloud-native NAC systems are inherently designed to be accessible from anywhere, which is a substantial advantage for organizations with multiple sites or those that support remote workforces. This means that security policies can be managed and enforced consistently across all locations without needing physical presence.
Disaster Recovery and Redundancy: Cloud-native services typically include robust disaster recovery plans and offer greater redundancy. Data and services are often replicated across multiple locations in the cloud provider’s network, ensuring more reliable service availability and data integrity in case of a disaster.
Security and Compliance: Cloud providers invest heavily in security, often more than an individual organization can afford for their on-premises systems. This includes physical security of the data centers, cybersecurity measures, and compliance with various regulatory standards, which can enhance the overall security posture of the organization using cloud-native NAC.
Cloud-native Network Access Control (NAC) solutions, like many other cloud-native services, offer several management advantages over traditional on-premises deployments. Here are some reasons why cloud-native NAC is generally easier to manage:
Simplified Infrastructure Management: With cloud-native NAC, the underlying infrastructure, including servers and databases, is managed by the cloud service provider. This removes the need for organizations to manage physical hardware, perform hardware upgrades, or troubleshoot hardware issues, which can be time-consuming and require specialized skills.
Automatic Software Updates: Cloud-native services are typically maintained by the provider, which includes regular software updates and patches. This ensures that the system is always up to date with the latest security features and compliance standards without requiring manual intervention from the organization’s IT staff.
Scalability and Flexibility: Cloud-native NAC solutions can be scaled easily to accommodate growing numbers of users and devices or to adjust to smaller needs during off-peak times. This scalability is typically seamless, not requiring additional physical infrastructure, and can often be managed through simple administrative interfaces.
Centralized Management: Cloud-native NAC solutions allow for centralized management of network access policies, which can be applied uniformly across all locations and devices. This is particularly beneficial for organizations with multiple offices or remote workers, as it eliminates the need to manage multiple instances or configurations locally.
Reduced Total Cost of Ownership (TCO): By reducing the need for on-site equipment, dedicated staff, and ongoing maintenance, cloud-native solutions can lower the total cost of ownership. The subscription-based pricing model often associated with cloud services also helps in budgeting and cost prediction, shifting capital expenditures to operational expenditures.
Faster Deployment and Integration: Deploying cloud-native NAC solutions is typically quicker and less complex than setting up on-premises systems. Cloud services are designed for easy integration with existing IT environments and other cloud-based applications, using APIs and standardized protocols.
Enhanced Disaster Recovery: Cloud providers generally offer robust disaster recovery capabilities as part of their service offerings. This means that your NAC system is likely to be backed up regularly and can be restored quickly in case of a disaster, without the need for complex disaster recovery procedures on-premises.
Access from Anywhere: As cloud-native solutions are hosted online, administrators can manage the network, update policies, and monitor security from anywhere with an internet connection. This flexibility is invaluable for maintaining security in today’s mobile and often global business environments.
Improved Security: Cloud service providers typically invest heavily in security, including physical security of data centers, cybersecurity measures, and compliance with regulatory standards. This often surpasses the capabilities of individual organizations, especially small to medium-sized enterprises.
By leveraging these advantages, organizations can focus more on strategic activities rather than the intricacies of network access control management, making cloud-native NAC not only easier but also potentially more effective.

Portnox supports the principles of Zero Trust security by providing comprehensive network access control that doesn’t inherently trust any entity inside or outside the network. Instead, it continuously verifies and authenticates access based on real-time assessments. Here’s how Portnox Cloud aligns with and supports Zero Trust principles:
Least Privilege Access: Portnox ensures that users and devices are granted the minimum necessary access to network resources. This limits the potential impact of a compromised account or device, as they would only have access to a constrained set of resources.
Continuous Verification and Authentication: In a Zero Trust model, trust is never assumed and must be continually earned. Portnox Cloud continuously verifies the security posture and compliance of devices before and during their connection to the network. This includes real-time health checks, ensuring that only compliant devices can maintain network access.
Microsegmentation: Portnox facilitates network segmentation, a key component of Zero Trust, which involves dividing the network into smaller, distinct security segments. By doing so, it restricts lateral movement within the network, thereby minimizing the attack surface and reducing the impact of potential breaches.
Contextual and Adaptive Policies: Portnox Cloud allows for the creation of dynamic access policies that adapt based on contextual data, such as device type, user identity, location, time of access, and other security attributes. This adaptive policy enforcement is critical in a Zero Trust architecture where access decisions must consider the comprehensive security context.
End-to-End Encryption: Portnox ensures that data in transit is encrypted, which protects the integrity and privacy of data as it moves across the network. This is particularly important in a Zero Trust model, where the assumption is that attackers can be present on or inside the network.
Visibility and Monitoring: Portnox provides extensive visibility into all devices connected to the network, including personal and IoT devices. This visibility is essential for monitoring and detecting potentially malicious activity within the network, aligning with the Zero Trust principle of “assume breach,” where monitoring for unusual behavior becomes crucial.
