What is SD WAN and SASE?

SD-WAN (Software-Defined Wide Area Network) provides an advanced solution for optimizing and managing wide-area networks, with a focus on improving connectivity and performance. On the other hand, SASE (Secure Access Service Edge) integrates both networking and security into a cloud-first approach, ensuring secure access for users and devices, no matter their location.

What is the Difference Between SD WAN and SASE?

The key difference between SD-WAN and SASE lies in their focus. SD-WAN enhances network performance and connectivity by managing traffic across multiple locations, while SASE integrates security with networking, providing a unified, cloud-based solution for secure access anywhere.

SD WAN	SASE
SD-WAN or (Software-Defined Wide Area Network).	SASE or (Secure Access Service Edge).
Manages and optimizes wide-area networks.	Trust Access is Not inherently supported.
