Hadrian has raised $1.4B in a Series D round, a massive infusion for the agentic AI offensive security platform. The company, which helps security teams identify and validate internet-facing vulnerabilities before they’re exploited, is now armed with capital that signals serious momentum in a crowded cybersecurity market.
The funding arrives as Hadrian leans into its pitch that AI can cut through the noise of threat detection-automating asset discovery, emulating attacker behavior, and flagging only what’s truly exploitable. With claims of 10x visibility into critical risks and an 80% faster remediation cycle, the company is positioning itself as a practical layer atop existing security stacks, not a replacement. The round’s backers weren’t disclosed, but the size alone suggests confidence in Hadrian’s enterprise traction.
