Positioning guardrails
Best for
- Security teams that need proof of exploitability rather than another vulnerability list
- Regulated enterprises and government agencies validating controls across on-prem, cloud and hybrid estates
- Organizations that must evidence penetration testing for PCI DSS, SOC, DORA, GDPR, NIST or CMMC audits
- Teams replacing or supplementing periodic manual pentests with continuous autonomous testing
Ideal size: Security team of 5+ people · Mid-market to enterprise with a dedicated security function
Not for
- Buyers who need a published, fixed list price before purchase
- Environments that cannot allow any active exploitation testing against production systems
- Small IT teams with no capacity to remediate findings
- Teams looking for a passive vulnerability scanner or a SIEM replacement

Frequently asked questions
What does NodeZero actually do?
NodeZero autonomously executes real attack techniques against your production environment to prove which exposures are genuinely exploitable, prioritizes what matters, and offers 1-click verify retests so you can show remediation. Horizon3 positions it as an alternative to static scanners and periodic, opinion-based risk scores.
How is NodeZero priced?
Horizon3 does not publish list prices. NodeZero is sold as an annual subscription across four packages: Flex (autonomous episodic pen testing), Core (continuous pen testing), Pro (adds Tripwires and Rapid Response) and Elite (adds risk-based exposure management features). WebApp Pentesting and Enhanced or Premier support are add-ons. Expect a quote-based evaluation.
Is it safe to run against production systems?
The vendor states NodeZero runs safely in production without agents or disruption and has achieved zero downtime across all production tests, which it says earned trust in high-security environments. Buyers in clinical or regulated networks should still validate scope and change-control requirements during a pilot.
Which compliance frameworks does it support?
Horizon3's compliance offering explicitly lists PCI DSS v4.0 and updated SAQs, SOC, DORA, GDPR, CIS, NIST and CMMC, delivered with OSCP-certified pentesters plus the NodeZero platform. Customers get a penetration test report, prioritized fix actions, dashboard access and 1-click verify proof of remediation for auditors.
Does NodeZero offer an MCP server?
Yes. The NodeZero MCP Server is listed as a capability in every published package, from Flex through Elite, so it is available without upgrading to the top tier.
What support is included?
Support is included with every NodeZero subscription, with community access and self-service resources. Enhanced support adds faster response, live-agent chat, quarterly engagement, remediation advisory and an assigned customer success manager; Premier adds highest-priority support, monthly engagement, architecture guidance and an optional designated support engineer.
