Zero Trust SD-WAN Access at a Glance
The SD-WAN (Software-Defined Wide Area Network) market is growing rapidly as companies increasingly depend on cloud connectivity and require flexible, secure, and efficient networks.
SD-WAN offers numerous advantages, such as optimizing traffic across multiple WAN links, improving access to key applications, and enabling centralized management. Teldat’s SD-WAN can be deployed in the cloud or on-premise in customer datacenters, and its overlay model simplifies control and configuration by abstracting the underlying infrastructure.
Flexibility is another key benefit—such as the scalability to add new sites in just a few clicks. It also seamlessly supports both traditional MPLS connections and rapidly growing access technologies like FTTH and 5G.
Security is equally critical in SD-WAN networks—integrating advanced traffic protection features is no longer a choice. Integrated protections like firewalls, IDS/IPS, anti-malware, and sandboxing must be implemented to keep threats out. In addition, fine-grained access control is required to ensure users only reach what they’re authorized to—nothing more.

Understanding and Extending Zero Trust to SD-WAN
Combining SD-WAN with Zero Trust strengthens both security and business connectivity. While SD-WAN enhances network performance, Zero Trust removes implicit trust by continuously verifying every user, device, and application before granting access. This ongoing verification reduces the risk of unauthorized access and protects critical applications across distributed environments.
A key pillar of Zero Trust in SD-WAN is the principle of least privilege: users are granted access only to the resources they need. Micro-segmentation divides the network into secure zones, limiting lateral movement and containing threats in the event of a breach. SD-WAN also encrypts traffic with protocols like IPsec, ensuring data is protected in transit and minimizing the risk of malicious interception.
Visibility and continuous monitoring are also essential. Zero Trust SD-WAN leverages advanced tools such as real-time traffic analysis, behavior analytics, and anomaly detection to uncover suspicious activity.
With integrated ZTNA, unified access policies are applied consistently to both internal and remote users. This enables a proactive security approach and supports hybrid and multi-cloud environments—delivering secure, agile, and resilient connectivity in the face of today’s cybersecurity challenges.
Zero Trust SD-WAN Solutions and Teldat Products
Context
Zero Trust SD-WAN is essential for companies looking to strengthen security across distributed networks, minimize risk, and gain better traffic control. SD-WAN improves connectivity between branches offices, data centers, and cloud services, while delivering strong protection against advanced threats.
Zero Trust complements SD-WAN by eliminating implicit trust and reducing the attack surface. In traditional networks, compromising a single point can allow attackers to move laterally without restriction. Zero Trust addresses this with micro-segmentation—restricting access to only the necessary resources and blocking unauthorized movement within the network.
Teldat’s Zero Trust SD-WAN delivers the internal segmentation and advanced security today’s networks demand. With integrated ZTNA for remote users, it enables unified, simplified access policy management across the entire platform. Customers can build their WAN using a secure overlay that interconnects remote sites with data center or cloud services—all within Teldat’s be.Safe and SD-WAN suite.
Zero Trust SD-WAN Architecture
Teldat deploys a hybrid architecture built around a Broker, which serves as the central SD-WAN hub. It receives encrypted tunnel connections from branch offices and remote users, and it’s where authentication, device compliance checks, and granular access policies are enforced.
Zero Trust connectors are deployed close to applications—whether in data centers or public cloud environments. Customers can install as many connectors as needed to match their network’s scale. Available as physical or virtual appliances, these connectors run Teldat’s hardened operating system and include built-in threat inspection features.
Remote users connect via an agent installed on their device, while on-site users are authenticated through seamless Active Directory integration. Other endpoints, such as IoT devices, are managed using granular access policies and identified by IP or MAC address, especially when integrated with NAC systems.
Polities and Advanced Features of Zero Trust SD-WAN
Once the components are deployed and users have the agent installed on their devices, applications can be registered by host, URL, IP address, or port. Combined with directory-based authorizations, this enables the creation of specific, profile-based access policies tailored to each user—regardless of their location.
Advanced Security Features
Alongside the be.Safe Pro product suite, Teldat offers a wide range of advanced security capabilities. Administrators can easily apply threat prevention profiles to any traffic flow—whether directed toward internal applications or the Internet—ensuring consistent protection across the entire platform. Additional features include URL filtering and application control.
IoT devices are secured without the need for an installed agent. Since they connect via Teldat’s physical appliances through encrypted tunnels to the SD-WAN service, their origin can be identified and visibility and control policies can still be enforced.
