Our verdict on Net Bright Firewall Rule Optimizer
Net Bright Firewall Rule Optimizer analyzes firewall configuration files to identify shadowed, redundant, mergeable, overly permissive, and unused rules. It is aimed at teams that need to review accumulated policies, prepare for audits, migrate firewalls, or assess proposed changes. The browser-based tool supports Palo Alto, Fortinet, Cisco ASA/IOS, Check Point, and pfSense/OPNsense, giving it a multi-vendor scope for organizations working across those platforms.
Rule hygiene is the central strength. Findings map to CIS and PCI-DSS, and the tool provides a security score with a grade and breakdown. Teams can examine zone-to-zone exposure through a heatmap, compare configuration changes, and check exposed services against CISA KEV entries. A what-if rule simulator and packet tracer add ways to assess proposed rules; optimized configurations, HTML/PDF reports, and rule CSVs support follow-up analysis. According to the vendor, configurations remain in the user's browser rather than being uploaded.
The published plan is Free Firewall Rule Optimizer at $0, described as a free tool, but access must be requested through Net Bright. This is analysis and optimization rather than change-control software: the listed capabilities do not automate policy changes. Teams looking for rule review across the supported vendors, compliance mapping, or migration analysis may find the scope appropriate. Organizations that need automated enforcement or a system to manage policy changes should look for a broader change-control product instead.
