Fight AI with AI

Prove your security.
Continuously.

NodeZero walks the attack paths a real adversary would — safely, in production, every day. You get continuous evidence of what’s exploitable, what your controls actually blocked, and what needs to be fixed. Defensible answers for your board, your auditors and the regulator, grounded in tests that were actually run. Delivered in Australia and New Zealand by Drochaid.

Not a scanner. Not an annual pentest. Continuous proof your defences hold.

What is NodeZero

An autonomous offensive security platform

NodeZero safely runs the attacks a real adversary would — against your production environment, every day. It chains misconfigurations, exposed credentials and exploitable services into complete attack paths, then shows you exactly what an attacker could reach, what your controls stopped, and what to fix first. A one-click retest proves the fix closed the path.

Hack. Fix. Verify. Repeat.

Stop guessing. Start proving.

Move from vulnerability management to closing proven attack paths — in just a few clicks.

Step 01

Hack

Knowing a weakness exists isn’t enough. Safely run real attacks in production to prove what an attacker could actually exploit.

Step 02

Fix

In an ocean of vulnerabilities, fix the ones proven to endanger your business — with proof-based remediation guidance.

Step 03

Verify

Don’t just check a box. Re-test to confirm the threat is gone and prove your risk has actually been reduced.

Step 04

Repeat

Your risk changes every time your environment does. Keep testing — every change, every day — so you stay secure.

… and repeat, continuously

Evidence, not opinion.

Don’t just take our word for it.

Horizon3.ai is trusted by global governments, Fortune 10 giants and major healthcare providers, where the need for security and safety is absolute.

…without taking an attacker’s perspective by considering actual attack vectors that they can use to get in, you really can’t be ready.

Critical infrastructure

The SOCI Act: eleven sectors where proof is now a legal obligation

The Security of Critical Infrastructure Act covers 11 sectors and 22 asset classes. If your organisation operates a registered critical infrastructure asset, you must maintain a board-approved Critical Infrastructure Risk Management Program — and under the Enhanced CIRMP Rules registered in June 2026, entities operating designated high-risk asset classes must demonstrate their cyber framework is implemented, not just documented. NodeZero produces that evidence: real attacks run against your environment, what held, what didn’t, and proof the fixes closed the paths.
