Secure Access Service Edge (SASE) is a network architecture framework that integrates wide area network (WAN) and security controls delivered from the cloud directly to edge devices. This approach eliminates the need to route traffic through a data center, making it more efficient for today's cloud-centric applications. By combining networking and security, SASE helps organizations adapt to the challenges of hybrid work and the increasing number of IoT devices.

Zero Trust Network Access (ZTNA) provides a more secure alternative to traditional VPNs by implementing least privileged access principles and granular access controls at the application level based on user identity. This means that remote workers can access applications securely without exposing the entire enterprise network, reducing risks associated with unrestricted access and protecting against web-based threats like ransomware and phishing.

Unified Secure Service Edge (SSE) offers several advantages, including improved security for cloud-based data and streamlined network management. It helps organizations monitor and control data movements to prevent breaches, supports the modernization of branch office networks by eliminating latency from traditional MPLS architectures, and provides centralized management for easier deployment. This approach empowers organizations to meet the demands of hybrid work and digital transformation while safeguarding sensitive information.
