AI Hacking Requires Penetration testing Supported by AI
Most organisations conduct a penetration test once or twice a year. The report lands, the critical findings get patched, and the medium and low findings sit in a backlog. Three months later, a new CVE drops, a misconfiguration creeps into a deployment or an unpatched legacy system gets forgotten. The test that was supposed to validate your security posture no longer reflects reality.
This is not a criticism of penetration testing. It's a criticism of how it's been delivered as a point-in-time exercise in an environment that changes continuously. This point-in-time approach is compounded by attackers only using the latest attacks that work while your IT team has to patch using out of date test results. The NodeZero pentesting & security platform from Horizon3.ai can help you keep up by continuously testing for vulnerabilities and verifying the fixes work.
The Problem with Prioritising by Severity Score
When a vulnerability scanner returns 400 findings, security teams inevitably triage by the Common Vulnerability Scoring System (CVSS) score. The problem with these severity scores is they measure theoretical risk, not actual exploitability in your specific environment. A critical-rated Common Vulnerabilities and Exposures (CVE) finding on a system that isn't reachable from any attack path is less urgent than a medium-rated misconfiguration that chains into full domain compromise.
The gap between "what a scanner says is critical" and "what an attacker would actually use" is where organisations get breached. Attackers don't wait for a list to be updated for permission to use an attack path. The NodeZero pentesting & security platform from Horizon3.ai can help prioritise by the real exploitable threats not just theoretical threats.
Continuously Test Systems. Prioritise Fixes by Exploitability
NodeZero, from Horizon3.ai, takes a fundamentally different approach to pentesting and security. Rather than producing a list of vulnerabilities, it autonomously executes real attack techniques in your live production environment. With no agents and no disruption it maps the full attack paths an adversary could actually follow and exploit. It then tells you which attack paths or vulnerabilities matter the most because it has proved they're exploitable end-to-end. It's not theory.
When you fix something, NodeZero retests it. You actually get evidence that the fix worked and not just an assurance. You have a genuine way to audit the fixes are working and show compliance.

With 225,000+ pentests run in production and customers who are in Government, Defence and the Fortune 500, NodeZero has become the benchmark for organisations that want continuous, evidence-based security validation rather than an annual report with a checklist.
If you're still relying on periodic manual testing to understand your security risks, it's time to see what continuous autonomous pentesting looks like with OneDot61.
