Transform Exposure Management
Move from vulnerability management to closing proven attack paths.
Hack
Prove exploitability with real attacks.
Knowing a vulnerability exists isn’t enough. You need to know if it’s actually exploitable.
Fix
Prioritize what actually matters.
In an ocean of vulnerabilities, prioritize the ones that are proven to endanger your business.
Verify
Close the loop on every fix.
Don’t just check a box. Re-test to confirm the threat is gone and prove your risk has actually been reduced.
Repeat
Prove continuous resilience.
Your risk changes every time your environment does. Continuously find weaknesses before attackers do — so you stay secure through every change, every day.

The State of Assumed Security
Most organizations measure activity, not resistance. This report reveals where security assumptions break and real exposure begins.
Report
Mythos didn't break cybersecurity
Mythos didn’t create new risk—it exposed how quickly vulnerabilities can become real attack paths.
Proactively prove that you’re resilient.
NodeZero® isn’t a scanner. We show you the real risk and impact on your business. Know exactly where you stand so you can stop guessing and start proving your security posture with confidence.
