Your VPN is visible on the internet. To users, scanners, and attackers alike.
Your VPN is visible on the internet. To users, scanners, and attackers alike.
Shodan and automated scanners continuously map public services: VPNs, access gateways, and login portals. When a new vulnerability appears, attackers do not need to find targets manually. They already have lists of exposed systems.
Secfense Ghost removes the problem at the source by making protected services stop responding to unauthorized traffic.

Traditional VPN defense
VPN exposed to the internet 24/7
Shodan indexes IP, model, and version
Scanners see open ports and services
Zero-days can be exploited before patching
Maintenance windows extend exposure
