GOAD (Game Of Active Directory) is an intentionally vulnerable cyber range used by pentesters and defenders to explore common attack techniques in a Windows Active Directory environment. It's chock full of real-world misconfigurations and vulnerabilites, the type we see all the time in client environments. As such, it's a great way to understand the capabilities…

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…

Vulnerability management started with scanning — identify assets, fingerprint software, and match scan findings to known CVEs. Then came “risk-based” approaches that promised smarter prioritization. But in practice, most programs still just patch what scores the highest. Risk is inferred, not proven. Fixes are assumed to work. And security teams are left guessing what actually…

Scanning and patching aren't enough. Learn the critical difference between being vulnerable and being exploitable—and why it's the key to preventing real-world breaches.
