Awareness doesn’t equal defense. Threat Actor Intelligence helps you go beyond the headline: “Are these attackers using techniques that would actually work in our environment?”

Horizon3.ai’s NodeZero® delivers $6.78M annual cost avoidance by replacing pentests, reducing scanner costs, and boosting security ops.

Pentesters and red teams share a common goal: improving an organization’s security posture. But their objectives, scope, and methods differ. NodeZero® helps both teams succeed by showing what’s truly exploitable, so you can cut through the noise and continuously validate your security posture.

Vulnerability management wasn’t designed to deal with real attackers. That’s the problem. Most programs drown in scan data, chase vulnerabilities with high CVSS scores with no context, and still can't answer a simple question: Are we exposed? This isn’t just another dashboard. You’ll see how NodeZero: If you're tired of measuring risk with guesswork, this…

Enterprises are racing to harness AI to automate workflows, secure infrastructure, and accelerate decision-making. But here’s the uncomfortable truth: AI that doesn’t see your environment through an attacker’s eyes is operating blind.

When we set out to build the first version of the NodeZero MCP Server, we had two guiding principles: Most Model Context Protocol (MCP) servers today are overpowered and underdefended. They often: We didn’t build ours that way. The NodeZero MCP Server is a constrained, API-native runtime designed to give agents safe, structured access to…
