Minimize cybersecurity risk. Focus on what matters.


NodeZero™ provides continuous autonomous penetration testing as a true SaaS offering. With NodeZero, cybersecurity teams proactively find and fix internal and external attack vectors before attackers can exploit them.


External Penetration Testing with NodeZero

With a combined view of external and internal pentests, you’ll understand your complete cyber risk profile across your entire environment.

How NodeZero Works

NodeZero is a true self-service SaaS offering that is safe to run in production and requires no persistent or credentialed agents. You will see your enterprise through the eyes of the attacker, identify your ineffective security controls, and ensure your limited resources are spent fixing problems that can actually be exploited.

Critical Impacts

There are 2 types of security problems: issues that require you skip lunch and cancel plans with your family to fix, and everything else that gets added to your backlog of work. With NodeZero, we identify “Critical Impacts” that must be urgently fixed, or you’ll become the next news headline.



Attackers chain together misconfigurations + harvested credentials + vulnerabilities + dangerous product defaults into attack vectors. NodeZero helps you understand the attack vectors that lead to a critical impact, so you know exactly what to fix in order to disrupt the kill chain.



Tired of dealing with false positives? With NodeZero, the next time you alert your team to a serious cybersecurity problem, you will have proof-of-exploit in hand.

Best Practices


Best Practices

We don’t want to just PWN you. Our Best Practices view helps you understand your security posture across several dimensions that we, as security practitioners, believe are important. Why wait for a breach to prove to your boss that you’re secure?



You may be secure today, but what about tomorrow when your environment has changed? Continuously assess your security posture, and quickly compare NodeZero results to see what new weaknesses have been added or fixed.



NodeZero is designed to be safe to run in production. Define the scope of the operation – IP ranges it should stay within, IP ranges it should avoid – or let it intelligently identify the scope for you. You also have the ability to enable or disable specific attacks, if you want to be extra cautious.



This is how long it took NodeZero to compromise a large financial institution.

No humans. No custom scripts.

Let our experts walk you through a demonstration of NodeZero, so you can see how to put it to work for your company.

Why NodeZero?

Like APTs, ransomware, and other threat actors, NodeZero discovers and fingerprints your internal and external attack surface, identifying the ways exploitable vulnerabilities, misconfigurations, harvested credentials, and dangerous product defaults can be chained together to facilitate a compromise.


NodeZero will help you focus on fixing problems that can actually be exploited, saving you and your team from chasing down unexploitable vulnerabilities and false positives.


You’re up and running an autonomous penetration test in minutes using our self-service portal or API. There are no credentialed agents to install or attack scripts to write.


You can assess your entire organization in a matter of hours, versus waiting weeks or months for consultants to manually run scans and produce reports.


With NodeZero, you can assess your entire network from the attacker’s point of view, not just a sample. Our algorithm fingerprints your external, on-prem, IoT, identity, and cloud attack surfaces.


Our goal is to create a bias for action – helping you quickly find, fix, and verify that an exploitable problem is no longer a threat. The Red and Blue teams must work together, and NodeZero sets the conditions for a Purple Team culture!
