Prove and sustain least-privilege access across your firewall estate.
Find unused, duplicate, and over-permissive rules. Automate recertification with approvals. Reduce your attack surface and prove it, quarter over quarter.
Why least-privilege firewall program is hard to get right.
Firewall rules accumulate over time. A rule is added to enable a new application or temporary vendor connectivity; months later, the application is retired or the vendor is replaced, but the rule remains. Others are shadowed or superseded by newer, broader rules, yet both stay active. Some rules are so permissive they are effectively dead weight. Together, unused and over-permissive rules bloat your rule base, increase audit burden, and expand your attack surface. Finding them manually is slow and subjective; proving they can be deleted safely requires business sign-off that spans teams and vendors. Without a structured recertification process, the same bloat grows back.
Unused and shadowed rules are scattered across multiple firewalls and vendors; no automated way to spot them.
Over-permissive rules — any-to-any or excessive port ranges — are hard to quantify and justify for removal.
Recertification requires sign-off from business owners, but tracking who approved which rules and when is manual and fragile.
Without continuous monitoring, rule cleanup is a one-time project that decays as soon as the next change goes in.
Where OpClerk fits, point by point.
A direct, auditable line from each requirement to the capability that satisfies and evidences it.
Your rule base is the detailed blueprint of who can access what. OpClerk analyzes and stores this data inside your environment, so your firewall policy and recertification records never leave your perimeter.
Common questions.
OpClerk correlates policy rules with actual network traffic observed across your firewalls and cloud platforms over a rolling window (typically 90+ days). Rules with no matching traffic are flagged as unused — confirmed during scoping against your environment.
No. OpClerk identifies candidates and initiates recertification workflows with business approvals. Your team makes the final delete decision and applies it through your existing change process.
Yes. OpClerk normalizes policy from Palo Alto, Fortinet, Cisco, Check Point, Juniper, and cloud platforms, so one recertification cycle covers your entire multi-vendor estate.
