Edge Decay: How a Failing Perimeter Is Fueling Modern Intrusions

This report warns that the enterprise perimeter—edge devices such as firewalls, VPN concentrators, and load balancers—has become a primary target for attackers who exploit zero-day vulnerabilities, automation, and firmware implants to gain persistent access, harvest credentials, and pivot into identity infrastructure; it cites cases involving F5 BIG-IP, Check Point, Cisco ASA (ArcaneDoor/RayInitiator/LINE VIPER) and mentions APT actors and relay networks, urging a shift from perimeter assumptions to continuous validation and attack-lifecycle visibility.
