Horizon3.ai

Horizon3.ai NodeZero. Autonomous pentesting that validates attack paths continuously and turns exploitable exposure into an actionable remediation queue.

What NodeZero is

NodeZero is a platform for autonomous internal, external, cloud, Kubernetes and Active Directory pentesting. It is designed to validate attack paths with controlled exploitation rather than treating every scanner finding as equally urgent.

How autonomous pentesting works

1. Hack: test the defined scope with real, bounded attack techniques.
2. Fix: prioritise the weaknesses that create a usable attack path.
3. Verify: retest remediation and confirm whether the path is closed.
4. Repeat: run the validation again as infrastructure, identities and exposure change.

The platform can operate without agents installed on every system. The deployment model and test profile must be designed carefully for production, legacy and OT-sensitive environments.

Technical coverage

• Internal pentesting: privilege escalation, lateral movement and access to sensitive resources.
• External pentesting: public domains, services, exposed assets and associated credentials.
• Cloud and Kubernetes: IAM, exposed storage, excessive permissions, RBAC and container escape paths.
• Active Directory: weak credentials, unsafe delegation, service accounts and privilege paths.
• Third-party exposure: validate the paths created by supplier relationships and external dependencies.

When NodeZero is useful

It is relevant for organisations with regulatory pentesting requirements, large vulnerability backlogs, post-incident validation needs and MSSPs that want to offer continuous exposure validation to customers.

NodeZero compared with a scanner

A scanner reports potential weaknesses. Autonomous pentesting validates whether a weakness can be chained into a meaningful attack path in the customer’s environment. The two controls can coexist: scanning gives breadth, while attack-path validation improves prioritisation.

Frequently asked questions

Can autonomous testing disrupt production?

Testing must use an approved scope, safety profile and escalation process. Destructive actions should be excluded, and sensitive assets should be handled with conservative controls.

Does it replace a formal manual pentest?

Not always. A manual assessment may still be required by a regulator or contract. NodeZero complements that assessment with continuous validation between formal tests.

Does it require pentesting specialists?

The platform is designed to make findings actionable for security and IT teams, while scope, safety and remediation decisions still require qualified ownership.
