The NodeZero® platform empowers your organization to continuously find, fix, and verify your exploitable attack surface. Reduce your security risk by autonomously finding weaknesses in your network, knowing how to prioritize and fix them, and immediately verifying that your fixes work. NodeZero delivers production-safe autonomous pentests and other key assessment operations that scale across your largest internal, external, cloud, and hybrid cloud environments. No required agents, no code to write, and no consultants to hire. 

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants.
