GUEST ESSAY: Testing principles to mitigate real-world risks to ‘SASE’ and ‘Zero Trust’ systems

The Last Watchdog

Each of these elements must be validated across multiple security controls, like next-generation firewall (NGFW) and data loss protection (DLP) tools. SASE architectures must be validated end to end—from users and branches, through SASE points of presence, to cloud application servers.
