Best of Both Technologies – ZTNA and SD-WAN

When we talk about technology, security is one of the crucial elements that cannot be ignored. The digital landscape today is constantly at a move and organizations today are facing increasing challenges to secure their networks and optimize their connectivity.

But to overcome these challenges two revolutionary technology i.e., Software Defined Wide Area Network (SD-WAN) and Zero Touch Network Access (ZTNA) have proven emerge as powerful solutions. Together the strengths of SD-WAN and ZTNA provide a holistic approach that enhances network security, improves performance and enables seamless connectivity across modern enterprises. Today we explore these two technologies and how they work together to bring to you a myriad of benefits.

Understanding SD-WAN and security

Software Defined Wide Area Network (SD-WAN), a transformative technology, has made network management simpler and enhanced performance. By leveraging software-defined policies, organizations gain centralized control, application-aware routing, and the ability to prioritize critical applications over less important traffic. SD-WAN optimizes connectivity by utilizing various links, including MPLS, broadband, 4G/5G, and even satellite, thereby improving network resiliency, reducing costs, and enhancing user experiences.

SD-WAN solutions provide numerous benefits, such as cost savings, improved network performance, and enhanced security. However, with the increase in the complexity and scale of modern networks, traditional security solutions are no longer sufficient to protect against the ever-evolving threat landscape.

Understanding ZTNA

To understand ZTNA, we first need to know what zero trust strategy means. It is based on the idea that any user or device may have been compromised, due to which access to specific resources is restricted and only granted via multi-factor authentication. Zero Trust Network Access (ZTNA) is a powerful alternative to traditional VPNs as it embraces this zero touch model.

ZTNA is a security framework that redefines traditional network perimeters. Unlike the traditional perimeter-based security approach, which assumes trust within the network, ZTNA operates on a “never trust, always verify” principle. It ensures that every user, device, and application is authenticated and authorized before granting access to network resources. By implementing ZTNA, organizations can enforce granular access controls, minimize the attack surface, and reduce the risk of data breaches and unauthorized access. It also limits resources on a per-user and per-session basis, in contrast to the general network permissions granted via traditional.

Synergy of SD-WAN and ZTNA

When ZTNA and SD-WAN are combined, they create a powerful synergy that addresses both security and network performance challenges. ZTNA ensures that only authenticated and authorized users gain access to the network, regardless of their location or device. It verifies user identity, device health, and context before granting access. By incorporating SD-WAN, organizations can dynamically route ZTNA traffic across the most optimal network paths, based on performance metrics and application requirements. This combination provides a comprehensive security framework with an intelligent network fabric.

However, it is not easy for all SD-WAN vendors to provide this level of security. Most either offer basic security or worse, leave it to the consumer. Nexapp Technologies on the other hand is a one-stop solution for all your needs. We not only provide SD-WAN solution, but we make sure that the solution is protected and your security is never compromised with its in-house ZTNA. Making your entire experience smooth and hassle free.  

Benefits of SD-WAN and ZTNA collaboration 

The collaboration between ZTNA and SD-WAN offers several benefits to organizations:

a) Enhanced Security: ZTNA’s zero-trust approach complements SD-WAN’s network security features, ensuring that only authorized traffic reaches the network. It mitigates the risk of unauthorized access, lateral movement, and data breaches.

b) Improved Performance: SD-WAN’s intelligent traffic routing optimizes application performance, reducing latency and packet loss. This ensures that ZTNA traffic flows seamlessly across the network, enhancing user experiences.

c) Flexibility and Scalability: ZTNA and SD-WAN provide organizations with the flexibility to scale their network infrastructure and security posture as needed. They support cloud deployments, remote access, and the integration of multiple locations and branch offices.

d) Cost-Effectiveness: SD-WAN’s ability to leverage various network connections, including cost-effective broadband and wireless links, enables organizations to reduce their reliance on expensive MPLS connections without compromising security or performance.

Today, organizations are in need of a suite with advanced security and networking functions that can be extended to every user and device without any threat. Nexapp Technologies understands this need and hence provides all the benefits of SD-WAN as well as the security of ZTNA. Head over to Nexapp Technologies to find out more.
