NodeZero for pentesters & consultants

Recon. Asset discovery. Credential testing. Working through an Active Directory attack graph by hand.

All of that work is necessary. None of it differentiates you. It is the breadth work that gets in the way of the depth your clients remember.

NodeZero handles the breadth.

You deploy NodeZero at the start of an engagement — from a Docker host or OVA inside the network for internal work, from Horizon3’s cloud for external — and let it run. It handles discovery, enumeration, credential testing, and autonomous chaining of weaknesses into full attack paths. The Real-Time View lets you watch the operation unfold and inject credentials you find manually as the test proceeds.

While NodeZero grinds through the breadth work, you focus on depth. You chase the interesting finding it surfaced early in the run. You reverse engineer the custom application nobody else has looked at. You pivot into the weird segment NodeZero flagged. You build the narrative that turns a list of findings into a story the client’s board will remember.

At the end of the engagement, the report structure is already there. Every attack path NodeZero executed is documented with evidence, step by step, mapped to MITRE ATT&CK. You add your custom findings and the analytical depth that justifies your day rate. The client gets a more thorough assessment than either you or NodeZero could have produced alone, in less time.

Engagement cycle time drops. The breadth work that used to fill the opening days runs autonomously while you work on depth. That is either more capacity to take on more engagements, or more time per engagement to go deeper on the findings that matter.

Coverage improves. A human pentester can realistically chase a handful of attack paths in the available time. NodeZero works through the paths it can reach systematically, at machine speed. Things that get missed on rushed engagements — the abusable AD trust relationship, the Kerberoastable service account, the forgotten host still running default credentials — are the kind of weakness it is built to find and chain.

Retesting becomes a standard service. Instead of retesting being a separate engagement clients often skip, Quick Verify re-runs the exact attack path against an internal finding to confirm the fix closed it (verification for external findings is on Horizon3’s roadmap). You deliver the pentest, the client remediates, you retest, you confirm closure. That can become part of your standard offering.

Your value proposition shifts upward. You are no longer selling hours of reconnaissance. You are selling judgement, depth of analysis, custom attack research, narrative, and advisory — the things clients genuinely value and the things automation does not replace.

If you run a pentesting practice, NodeZero changes the unit economics. Senior pentesters stop doing junior work. Junior pentesters learn by watching real attack paths unfold in real environments, with their seniors teaching them where to dig deeper. Client work scales with headcount rather than being throttled by the availability of the most experienced staff.

If your firm offers, or wants to offer, continuous testing or managed pentesting services, talk to us about how NodeZero could fit your practice.

The skilled pentester’s value has never been in running the tools. It is in knowing where to look, what questions to ask, how to read an environment, how to string together findings into a story that changes a client’s behaviour. NodeZero does the execution work at speed and scale — Horizon3 reports it was the first AI to fully solve the Game of Active Directory, end-to-end, in 14 minutes. Your value sits above that layer: the judgement about what to chase, the contextual awareness of the client’s business, the research into custom applications, the advisory conversation that turns a report into a program of work.

Pentesters who work with NodeZero rather than compete with it are the ones positioned for what the industry is becoming. The commodity layer is getting automated. The judgement layer is where practices grow from here.
