Exposure Assessment

The CVE Exposure Window Calculator

The next critical vulnerability isn't the problem. The time it takes to protect against it is.

Select your firewall vendor and estimate the operational cost, exposure window, and patching burden created by critical firewall vulnerabilities.

1

Firewall patching burden

The labor your team spends keeping the firewall appliances themselves current, triage, testing, HA choreography, and fleet-wide rollout.

Illustrative baseline for routine, non-emergency patch pushes. Does not include Critical/KEV vulnerabilities — those are always treated as immediate, out-of-cycle patches regardless of this setting.

$0 / year

Unplanned Maintenance vs. Cato

+0.0 hrs

Low risk

0 remediation hours / yr

Cato delivers FWaaS and patches the platform for you, so there is no appliance fleet to triage, stage, or roll out. This burden drops to near zero.

2

System exposure during the patch cycle

Cato's Agentic CVE Mitigation (IPS Virtual patching) virtually patches in as fast as 45-min, protecting everything behind the Cato SASE Platform, giving your team time to assess risk and patch.

Did you know?

More attacks get in, fewer are fully closed, and closing them takes longer — so the exposure window keeps widening.

31% Initial Access

Exploiting vulnerabilities is now the #1 way attackers break in.

up from 20% last year

26% Remediation

Only a quarter of known exploited vulnerabilities are fully remediated.

down from 38% last year

43 days Time to Fix

And the median time to fully close a critical vulnerability keeps growing.

Methodology

This assessment loads a generated public-source CVE count file and combines it with user-provided environment assumptions. It estimates operational remediation burden; it is not a formal security assessment or guarantee of exposure reduction.
