# Horizon3.ai NodeZero: Pricing, Features & Alternatives (2026)

Autonomous production attack-path testing.

## Overview

Horizon3.ai's NodeZero autonomously runs real attack techniques in production without agents, then shows how an attacker would move and what to fix. The company says NodeZero is not a scanner and that it has recorded zero downtime across its production tests.

## Pricing

horizon3.ai does not list a price. AWS Marketplace lists a 12-month NodeZero Core package for 500 assets at $25,000, Pro at $32,500, and Elite at $42,500. Flex, a one-time test of 1,000 assets, is $15,000. A comment on the linked r/Pentesting thread says standard-tier MSRP is $50 per asset and Flex is $15 per asset, which matches that list math, but the contract prices above are the ones on the marketplace page.

## What users say

A commenter on r/Pentesting describes NodeZero's standard tier as continuous testing priced per asset, with room to negotiate.

On r/cybersecurity, a commenter who used NodeZero said it was disappointing, weak on web apps, and loud once it had a foothold. They treat it as a supplement to a human tester.

- “I'd disagree, I was a bit disappointed with NodeZero. A comparison to Burp isn't even realistic though, since NZ doesn't have web app capabilities at this point (unless it's a public PoC for a particular software).”Reddit · u/MouseMajor1337

- “H3's standard tier MSRP is $50 per asset, but that price can be negotiated. Standard tier gets you continuous (unlimited) testing for all Assets along with other features.”Reddit · u/FrerBear
