New York-based Beacon Security closed a $13 million seed funding round on July 16 to expand a data platform meant to give AI-driven security tools a cleaner, more trustworthy picture of enterprise environments. Notable Capital led the round, with Holly Ventures, AlphaDrive Ventures, SVCI, and Jefferies Family Office participating alongside more than 60 angel investors, including founders from Talon, Descope, Gem Security, Dig Security, and Cider Security.
Beacon’s pitch centers on a problem specific to agentic security tools. AI agents can only act as well as the data they’re given.
“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,” said Gal Tal-Hochberg, CEO and Co-Founder of Beacon.
Tal-Hochberg said Beacon was built to give organizations a trusted data foundation for deploying security agents compliantly, and that the new funding will help extend that approach into real-time posture management, detection and response, threat hunting, and broader operational analysis of security environments — at a scale existing tools haven’t matched.
The company’s platform normalizes and enriches telemetry across vendor products before routing it to security teams and their AI agents, aiming to remove the manual cleanup work that currently limits how much of that work can be automated. Beacon also ships a library of prebuilt agents for tasks like detection engineering and shadow-AI analysis.
“The real bottleneck isn’t detection; it’s trust in your own data,” said Oren Yunger, managing partner at Notable Capital, who is joining Beacon’s board.
Beacon enters an increasingly crowded field. Databahn and Abstract Security are pursuing nearly identical theses — using AI to automate telemetry normalization for security teams — while established vendors including Cribl and Fortinet have added similar agent-ready data layers to existing platforms this year.
The company says annual recurring revenue grew more than 300% in the first half of 2026, with customers spanning financial services, insurance, and technology. Beacon was founded in 2024 by Gal Tal-Hochberg, who previously built HiredScore before its $520 million sale to Workday, alongside co-founders Or Mattatia and Iddo Israely.
The capital infusion comes during a broader surge in agentic-security investment. Cybersecurity startups have closed 43 funding rounds totaling $600.3 million so far in 2026, according to a tracker maintained by FundedStartupsDaily, with two-thirds of that activity concentrated at the pre-seed and seed stage — the segment Beacon’s round falls into.
