Horizon3.ai NodeZero (autonomous pentesting)

What it does

NodeZero runs unlimited autonomous pentests that uncover exploitable attack paths, guide remediation and immediately verify that fixes worked, without installing persistent agents. Horizon3's AI page describes how NodeZero builds a cyber-terrain map of the environment, plans attack paths and makes decisions from what it observes, combining graph reasoning for attack planning, classical ML for classifying files and behaviours, and scoped GenAI for high-value targeting, executive narratives and data-compromise analysis. Use cases include internal, external, cloud, Kubernetes and web-app pentesting, Active Directory password audits, tripwires and rapid response to new CISA KEV exploits. Horizon3 markets a NodeZero Federal offering with FedRAMP High authorisation (vendor claim, not checked against the FedRAMP Marketplace in this run). The About page says Horizon3 is headquartered in San Francisco, CA. Pricing is not published.

Alternatives

• 
  7AI agentic security platform — Boston-based agentic security platform where swarms of specialised AI agents categorise, investigate and reach a determination on every alert, escalating only what needs a person, with optional managed service (PLAID ELITE).
• 
  Abnormal AI Security Mailbox (Abnormal AI for Government) — Autonomous agent for email security operations that triages user-reported emails, removes related malicious campaign messages across the organisation and replies to reporters; included in Abnormal AI for Government, which is FedRAMP and GovRAMP Moderate authorized.
• 
  Adaptive Security Agentic Email Security and Phish Triage — API-based 'agentic email security' that re-analyses inbound mail after native filtering with ML and LLM reasoning and removes confirmed threats across every inbox automatically (configurable human-in-the-loop thresholds). AI Phish Triage classifies employee-reported emails and acts on them, feeding Adaptive's simulations and awareness training.
• 
  Aikido Attack AI Pentesting — Belgian autonomous AI pentest: many agents map the app, test attack paths and re-exploit each finding to confirm it, with a same-day audit-grade report.
• 
  AIpentix (agentic continuous security testing and agentic red teaming, by Swipergy) — German continuous security-testing platform with an AI agent that signs in to the customer's application on its own, chooses follow-up checks and documents attack paths, with every tool run evidenced. Findings are grouped into remediation actions with owners, deadlines and Jira sync, and retests confirm fixes. Agentic red-team campaigns (recon, access, lateral and report agents led by human red teamers) are also offered for TIBER-EU and DORA TLPT style testing.
• A
  Andesite Human-AI SOC (Azimuth for Government) — Agentic SOC platform with configurable agents for alert triage, enrichment, investigation and remediation under analyst oversight; its government offering is FedRAMP High authorized.
