5,732 Firewalls in One Year — The Misconfigurations I See on Almost Every Box
Last year, our team audited 5,732 firewalls. That’s not a round number I picked for effect—that’s the actual count from our deployment and audit logs. FortiGates, Palo Altos, Sophos, Cisco ASAs, a few niche vendors. Enterprise data centres, bank branches, hospital campuses, manufacturing plants, multi-site retail chains. Every single one had at least one misconfiguration.
