Perimeter Service Exposure
Detecting legacy protocols, unpatched service banners, and active ports that should never be facing the public internet. A database port open to the world, an ancient FTP server still answering requests, or a remote management interface visible outside the firewall are not theoretical findings. They are the first things an automated scanner picks up on any routine sweep.
We document every externally reachable service, identify its version and protocol, flag what is unnecessarily exposed, and give your IT team the specific firewall rules needed to close each one.
What we look for
- Open database ports (MySQL, MSSQL, PostgreSQL) reachable from the public internet
- Exposed remote desktop and remote management interfaces (RDP, VNC, SSH on non-standard ports)
- Legacy file transfer services (FTP, Telnet) with version banners still active
- Administrative web interfaces visible outside the network perimeter
- Unintentionally exposed internal services identified through service banner analysis
