Beacon is an AI-powered security platform that helps security teams and AI agents prevent, detect, and respond to threats automatically. The platform gives defenders real-time visibility, important context, and security insights, helping them move faster and better protect their systems.

Since its launch, Beacon has seen rapid growth and adoption among dozens of enterprises across industries such as fintech, healthcare and hospitality. The company’s annual recurring revenue (ARR) grew by more than 300% in the first half of 2026.

Companies are adopting Beacon because traditional security systems were not designed for a world where AI can become both a target and a threat. As AI driven attacks grow faster, security teams need smarter tools to detect and respond quickly. Beacon helps organizations stay ahead of these evolving risks.

This funding comes after Beacon reached several key milestones, including the launch of its agentic data layer. The technology helps automatically organize and improve security data, making it faster, more flexible, and easier to manage without heavy engineering work.

Beacon is already used by Fortune 500 security teams in highly regulated industries. The platform helps companies find hidden threats, close security gaps, and protect their systems against modern attacks at greater speed and scale.

"Every CISO knows the real bottleneck isn't detection; it's trust in your own data. That problem doesn't go away when you add agents; it gets less forgiving," said Oren Yunger, Managing Partner, Notable Capital and Beacon board member. "The data-trust gap is exactly what Beacon is bridging in the AI era, bringing context to the security teams and their agentic workforce."

"We are growing fast, and Beacon lets our security data keep pace," said Olindo Verillo, Director, Detection and Response, Cerebras. "It gives us the agility to evolve on our own terms, and it has become part of how we run security day to day, increasingly with our agents doing that data work autonomously. Beacon is a core part of how we are building security for what comes next."
