Enterprise applications define the new the network perimeter. Today, that perimeter extends far and wide – anywhere your workforce has an internet connection. Find out how Portnox can protect your SD-WAN environment – no matter how distributed.
It doesn’t have to. The shift to SD-WAN and perimeterless networking is well underway. To ensure you’re maintaining a zero trust security posture across your network it’s imperative to have all access layers under lock and key – including wired, wireless and VPN. Find our how the Portnox Cloud extends across all of those layer to deliver zero trust access control from the cloud for your software-defined WAN environment.
Staying on the cutting edge of IT requires modernizing your cybersecurity, and zero trust architectures are at the forefront. But let’s face it, diving into zero trust can be a bit intimidating. With so many details and tools, it’s easy to get overwhelmed.
To see how businesses are navigating zero-trust, Portnox and TechTarget surveyed hundreds of IT and cybersecurity professionals across North America.
Staying ahead in IT means strengthening cybersecurity—and zero trust architectures now lead the charge. But let’s face it: embracing zero trust can feel daunting. With so many tools and complexities, it’s easy to lose your way.
To understand how organizations navigate zero trust, Portnox teamed up with TechTarget. We surveyed hundreds of IT and cybersecurity professionals across North America. Discover the insights we uncovered in our Trends in Zero Trust report.
SOFTWARE-DEFINED WIDE AREA NETWORK (SD-WAN)
SD-WAN is a software-based approach that simplifies and optimizes how organizations connect branch offices, data centers, and cloud environments. It intelligently routes network traffic over multiple connection types—such as broadband, MPLS, or LTE—to improve performance and reduce costs. When paired with Zero Trust access controls, SD-WAN can deliver both speed and security across distributed networks.
Implementing SD-WAN begins with evaluating existing network infrastructure and identifying business, performance, and security needs. Organizations then select an SD-WAN provider, deploy edge devices, and configure centralized policies to manage traffic and security. When integrated with identity-based access controls, SD-WAN supports both network efficiency and Zero Trust security.
SD-WAN enhances performance, reduces connectivity costs, and increases agility by centralizing network management and optimizing traffic routing. It also improves visibility into application performance. However, implementation can be complex, and vendor lock-in may limit flexibility. Pairing SD-WAN with strong Zero Trust security ensures consistent protection as organizations expand their networks.
MPLS relies on private circuits to guarantee performance but can be expensive and less flexible. SD-WAN uses software-defined policies to route traffic securely across public and private links, offering greater scalability and cost efficiency. When combined with Zero Trust access enforcement, SD-WAN delivers both high performance and secure connectivity across hybrid environments.
Yes. SD-WAN often uses encrypted VPN tunnels to protect data as it travels over public networks. This approach combines VPN encryption with SD-WAN’s intelligent routing and centralized management—enhancing both performance and security for users connecting to corporate or cloud-based resources.
It depends on the organization’s security model. Many SD-WAN solutions include basic security features, but advanced environments may still require next-generation firewalls for deep packet inspection and threat prevention. Integrating SD-WAN with zero trust access controls and network segmentation provides layered protection across users, branches, and cloud applications.
Portnox Cloud enhances SD-WAN security by layering real-time access control and device posture assessment on top of SD-WAN connectivity. While SD-WAN optimizes traffic paths and performance, Portnox ensures that only authenticated, compliant devices can access the network and critical applications. This integrated approach reduces risk from unmanaged endpoints and strengthens security across distributed sites without disrupting SD-WAN operations.
Yes. Portnox Cloud integrates with existing SD-WAN deployments to provide consistent access control and zero trust enforcement without requiring changes to the underlying SD-WAN infrastructure. Portnox evaluates user identity, device posture, and risk before granting access to SD-WAN-connected resources. This allows organizations to secure their SD-WAN environments while preserving performance and simplifying policy management.
