Quick answer
Secure Access Service Edge (SASE) combines networking (such as SD-WAN) and security services (secure web gateway, cloud access security broker, zero-trust network access and firewall-as-a-service) into a cloud-delivered service. It suits organisations with remote workers and cloud applications, replacing the old model of routing all traffic through a central data centre.
How to Adopt SASE#
Map users, sites and applications, start with zero-trust access for critical apps, consolidate tools gradually and monitor performance and policy coverage. For application-level security, pair SASE with secure development and testing. See our VAPT security testing and DevOps & cloud services.
