Autonomous pentesting

Full suite of penetration and operational tests. Assess at scale across on-prem, cloud, and hybrid infrastructure.

Test without scope, perspective, or frequency limitations.

Integrated threat detection

Auto-dropped honeytokens add protection against exploitable exposure with proven downstream business impact.

Get aircover without the overhead or noise.

Zero- and N-day alerting

Emerging threat intelligence and early alerting backed by Horizon3.ai’s expert attack team.

Stay ahead of bad actors— and out of the news.

Unified risk reporting

Unified data from continuous, comprehensive testing proves how your security posture evolves— over time and against peers.

See org-wide risk and trends like never before.

Transform offensive security with autonomous pentesting.

See how NodeZero gives you continuous, comprehensive risk assessment so you can manage exposure using proof, not probability.

NodeZero use cases

Replaced traditional scanning with NodeZero for real-world attack simulation. Enabled continuous testing with attacker’s perspective.

Keep up as risk continuously evolves

Penetration testing is the best sensor to understand risk: what’s exploitable and the business impact that’s at stake. Yet the cost and speed of manual testing can’t scale.

Enter autonomous penetration testing. Unlike automated solutions, NodeZero dynamically traverses your networks to chain together exposure just like a real-world adversary.

Integrated CTEM into MSSP services for always-on threat exposure management.

Streamline CTEM adoption

CTEM matures security teams beyond periodic scans to continuous, validated threat exposure insights and aligns remediation to business goals.

Accelerate CTEM outcomes by unifying the threat exposure discovery, validation, and prioritization into one NodeZero workflow centered on real production risk.

Simulates phishing, credential misuse, and lateral movement tactics.

Detect and contain bad actors

Overwatch for known vulnerabilities and other weaknesses in your environment ensures that you can reduce the blast radius of malicious activity.

Whether a fix is in-flight or you're accepting risk, NodeZero Tripwires slashes the overhead of threat deception and detection by auto-dropping precision honeytokens against critical exposure.

Get ahead of the news cycle

As emerging threats surface, you’re in a race against bad actors—but not all headlines apply to you. Time spent on Zero- and N-day threats that aren’t exploitable is time lost.

NodeZero Rapid Response delivers world-class attack research with tailored alerting for the emerging threats relevant to your unique environment, often before they’re in the news.
Evaluated third-party integration risks in cloud environment.

Don’t settle for self-reports

Vendors, partners, and connected third-party systems are often stepping stones for attackers to breach higher-value targets. If they lack security maturity, you’re exposed.

Assess third-party environments quickly and at scale with autonomous pentests. Get proof of exploitability so your suppliers and vendors can remediate their risk—and yours.

Validate security controls across 1,700+ IPs, uncovering network gaps and exploitable vulnerabilities monthly.

Get your money’s worth

Investments in your security stack—like firewalls, EDR, and IAM—are core to your defensive strategy. Yet, a best-in-class solution that’s misconfigured can’t earn its keep.

With production testing, NodeZero gives you concrete validation of whether your security controls are effective, and where they need to be tuned to deliver the value you expect.
