Beacon Security, a cybersecurity startup developing tools for AI-driven security operations, has raised $13 million in seed funding as companies look for ways to manage growing risks tied to artificial intelligence. The round was led by Notable Capital, with participation from Holly Ventures, AlphaDrive Ventures, SVCI, Jefferies Family Office and more than 60 cybersecurity founders and chief information security officers. Investors include founders from Talon, Descope, Gem Security, Dig Security and Cider Security. Beacon said it will use the funding to expand its platform, which is designed to give security teams and AI agents a cleaner and more reliable data foundation for detecting, investigating and responding to cyberthreats. The company, founded in 2024, says it has seen rapid early adoption among enterprise customers in sectors including financial services, insurance, technology, health care and hospitality. Beacon said its annual recurring revenue grew more than 300% in the first half of 2026, though it did not disclose revenue figures. Beacon is led by co-founder and CEO Gal Tal-Hochberg, who previously founded HiredScore, an HR technology company acquired by Workday for $520 million. He founded Beacon with Or Mattatia and Iddo Israely, who have backgrounds in cyber defense, offensive security and large-scale data infrastructure. “The acceleration of AI agents in the enterprise is creating a distinct need for a legible context layer for cyber defenders, which is fueling a fundamentally new security architecture,” Tal-Hochberg said. “We built Beacon to solve these challenges by providing the trusted data layer that allows organizations to deploy security agents compliantly and effectively.” Beacon’s platform sits between a company’s security data sources and the tools used by analysts. It is intended to normalize, enrich and organize data from multiple vendors so both human analysts and AI agents can work from a more complete and reliable picture. The company
