How to Secure Branch Networks Against Machine-Speed, AI-Driven Cyber Threats
Zscaler, Wednesday, September 23rd, 2026
Zscaler argues Anthropic's Mythos disclosure means unpatched device backlogs can now be chained into AI-built attacks.
Zscaler cites Anthropic's April Mythos disclosure, in which a frontier AI model without cybersecurity-specific training autonomously found and wrote exploits for thousands of zero-days, as proof that backlogged CVEs on unpatchable branch devices are now exploitable at machine speed.
Firewalls, VPN concentrators and OT controllers each have different vendors and patch cycles, and some can't be patched at all, so teams have long triaged by severity and left the rest.
The Cloud Security Alliance responded with eleven priority actions for getting "Mythos Ready," covering governance as well as architecture.
Zscaler argues a cloud-proxied Zero Trust branch model removes the attack surface these AI-composed chains rely on.
