Free Security Tools

Browser-based utilities from Cynfi that run entirely client-side — nothing you load is uploaded anywhere. Built to solve practical firewall and network security problems.

Firewall Rule Risk Analyzer

Parses a firewall configuration and scores every enforced rule for exposure risk — plain-English risk breakdowns, logging gaps, and default-allow detection. The combined analyzer auto-detects your vendor, or pick your platform directly below.

Runs entirely in your browser — no configuration data is stored on the server before, during, or after analysis. Source and documentation: github.com/cynfi/fwrra.

Fortigate to PanOS NGFW Rulebase Conversion Tool

Convert a FortiGate (FortiOS) firewall rulebase into equivalent Palo Alto PAN-OS NGFW policy — mapping objects, services, and security rules to speed up platform migrations.

Runs entirely in your browser — no configuration data is stored on the server before or after conversion. Maps interfaces to PAN-OS zones, converts objects, services, security policy, and NAT (VIPs & IP pools), and flags low-confidence conversions for review.
