A behavioral antivirus & EDR for Windows 11 that catches what malware does — so zero-day threats with no signature still get caught and killed.
Measured against Atomic Red Team on a clean Windows 11 VM. The attack tools report their own failure — “process failed to start”, “Failed to get process handle”. Prevention, not just alerts.
Seven behavioral sentinels watch processes, the network, files, the registry and DNS — and act the moment something turns hostile.
Catches techniques, not hashes. Novel and zero-day malware with no known signature still trips the sentinels.
Suspends or kills the culprit, deletes persistence, and freezes ransomware mid-encryption — automatically.
Every finding maps to a MITRE technique and carries a CVSS score — ready for triage and reporting.
Event-driven sentinels sleep until something fires. You will not hear the fans or feel the lag.
Killed files go to a locked vault. The engine restarts itself if an attacker tries to shut it down.
Throttles while a full-screen game runs, then snaps back to full protection the second you exit.
A selection of the techniques FlewHaul detects, each tested with real tooling — not a generic feature list.

A security tool should never become the hole in your defenses. The FlewHaul agent never opens a listening port and never sends your data anywhere — so it cannot be reached, hijacked, or turned against you.
