Stop guessing. Know your web filters work.
FilterGuard runs continuous automated tests from inside your network and alerts you the moment a filter drifts — before threats get through.
How FilterGuard works
Deploy the agent
A lightweight agent runs inside your network. Outbound-only — no inbound ports required.
Automated test jobs run
FilterGuard sends test requests through your filter on a schedule you control.
Get instant alerts
When a filter drifts — blocked URLs pass or allowed URLs break — your team is notified immediately.
Built for security teams
Continuous validation
Tests run automatically on your schedule. No manual spot checks.
Drift detection
Know within minutes when your filter configuration changes unexpectedly.
Multi-channel alerts
Receive notifications via Teams, Syslog, Splunk, or any webhook endpoint.
Full audit trail
Every test result is recorded. Export history for compliance reviews.
