Secure Access Service Edge (SASE)

Secure Access Service Edge (SASE) is a network architecture that combines wide-area networking (WAN) capabilities with comprehensive security functions delivered through a cloud-based service.

SASE integrates technologies like SD-WAN, Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Zero Trust Network Access (ZTNA), and firewall-as-a-service (FWaaS) into a unified platform. This approach ensures secure, high-performance access to applications and data from any location, whether users are working on-premises or remotely.

Key features of SASE include:

  • Combining networking and security in a single, cloud-native service
  • Providing secure access to applications and data from anywhere
  • Enforcing security policies through integrated tools like CASB, ZTNA, and SWG

Implementing SASE involves:

  • Converging network and security functions into a single platform
  • Enforcing consistent security policies across users and devices
  • Optimising network performance with SD-WAN and other technologies

SASE enhances security and simplifies management by providing secure, scalable access for modern, distributed workforces.
