NodeZero Test Types

Internal Pentesting
Run a pentest against your internal network. NodeZero runs on a Docker Host within your private network.
External Pentesting
Discover your public-facing assets and run a pentest against them. NodeZero runs the pentest from the Horizon3.ai cloud – no Docker Host required.
Cloud Pentesting
Run a pentest across your cloud and on-prem environments. NodeZero connects to both to identify and exploit hybrid attack paths.
AD Password Audit
Audit your users’ Active Directory passwords. NodeZero will reveal weak, breached, and re-used passwords.
Phishing Impact Testing
Discover what an attacker can do with phished credentials in your environment. NodeZero leverages phished credentials in order to validate user access and damage to the environment.
Rapid Response to CISA Kevs
Identify and act on emerging threats fast. NodeZero alerts you to zero-day and N-day risks in your environment and enables targeted testing and remediation before attackers can exploit them.
Fix Actions
Prioritize what matters most. NodeZero highlights the exact steps your team should take to remediate real, exploitable threats—so you fix what attackers would exploit first.

Horizon3.ai and NodeZero are critical in helping us focus on actual threats, improve ROI, and continuously enhance our security posture.

NodeZero use cases

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.

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.

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.

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.

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.
