Horizon3.ai (NodeZero) FAQ
How does NodeZero help organizations validate their security posture against real-world attacks?
NodeZero autonomously executes real attack techniques against a production environment, showing exactly how an attacker would move and what they could access. It provides evidence-based results that enable teams to prioritize the fixes that matter and instantly verify that remediation is effective.
How does NodeZero differ from Intelligence Node in testing security vulnerabilities?
While Intelligence Node focuses on retail analytics, NodeZero is an autonomous penetration testing platform that directly attacks a production environment to find exploitable vulnerabilities. Unlike Intelligence Node, NodeZero provides clear, evidence-based attack paths and zero downtime, making it suitable for high-security environments.
What are the main trade-offs when using NodeZero for penetration testing?
NodeZero requires production environment access, which may not be feasible for all organizations. Additionally, its autonomous testing may not replace manual penetration testing for complex, bespoke scenarios that require human creativity and nuanced judgment.
Which teams benefit most from using NodeZero for continuous security validation?
Security teams in government agencies and major enterprises benefit most from NodeZero, as it is trusted in high-security environments and provides continuous validation that adapts to every environmental change. Teams that need to eliminate noisy vulnerability lists and focus on proven attack paths will find NodeZero especially valuable.
How is NodeZero priced, and does it include a free tier?
NodeZero is a paid product and does not include a permanently free tier. Organizations interested in using it should contact sales for pricing details.
Can NodeZero run tests in production without causing disruption?
Yes, NodeZero is designed to safely run in production environments with zero downtime, as demonstrated by its track record of zero downtime across all production tests. It does not require agents and executes attacks without disrupting operations.
How does NodeZero help teams verify that vulnerabilities have been fixed?
NodeZero provides instant verification of remediation by retesting the environment after fixes are applied. It shows exactly whether the attack paths have been closed, allowing teams to confirm that their efforts are effective.
How does NodeZero adapt to changes in the production environment over time?
NodeZero uses AI to learn and adapt with every test, so it continuously validates security as the environment changes. This ensures that new vulnerabilities introduced by updates or configuration changes are identified and addressed promptly.
