Executive Abstract
Empirical review of zero-day vulnerabilities targeted in SSL-VPN, firewalls, and edge infrastructure throughout 2026.

Detailed Threat Intelligence Breakdown

Perimeter network appliances remain prime targets for pre-authentication remote code execution (RCE) exploits. Attackers leverage heap memory corruptions to spawn root shells.

Key Findings & Strategic Observations

  • Pre-auth RCE flaws in edge firewalls
  • Memory safety issues dominate zero-day zero-clicks
