Fencepost watches logs for hostile behavior and blocks the sources — and each installation contributes anonymized signals to a shared reputation network that protects all the others.

Worth knowing before you commit:

  • Parsers exist for common services; custom formats take a scenario file.
  • Blocking decisions run locally; the network only shares reputations.
  • Remediation supports firewalls, proxies and cloud APIs.
