Firewall Monitoring and Configuration Drift: Why One-Off Reviews Are Not Enough

A firewall can pass a review and still become risky weeks later. Emergency changes, vendor access, temporary troubleshooting, migrations, and undocumented object updates can all create configuration drift after the original audit is complete.

One-off reviews are useful, but recurring checks create a stronger operating rhythm. They help teams identify what changed, whether the change introduced new exposure, and whether previous remediation work has stayed in place.

ConfigSentry supports both manual audits and continuous monitoring workflows, making it easier to move from occasional evidence gathering toward regular firewall security visibility.
