Beacon Security Raises $13 Million to Build AI-Focused Cybersecurity Platform

Beacon Security, a cybersecurity startup specializing in AI-driven security operations, announced it has raised $13 million in seed funding. The round was led by Notable Capital, with participation from Holly Ventures, AlphaDrive Ventures, SVCI, Jefferies Family Office, and over 60 cybersecurity founders and CISOs, including founders from Talon, Descope, Gem Security, Dig Security, and Cider Security.

The company plans to use the funding to expand its AI-native platform, which sits between an organization's security data sources and the tools used by analysts. The platform normalizes, enriches, and organizes data from multiple vendors, providing a cleaner and more reliable data foundation for detecting, investigating, and responding to cyberthreats. This approach is designed to address the growing challenge of data trust in security operations, especially as AI agents become more prevalent.

Founded in 2024, Beacon Security is led by CEO Gal Tal-Hochberg, who previously founded HiredScore (acquired by Workday for $520 million). He co-founded the company with Or Mattatia and Iddo Israely, who bring expertise in cyber defense, offensive security, and large-scale data infrastructure.

The company reports rapid early adoption among enterprise customers in financial services, insurance, technology, healthcare, and hospitality. Its annual recurring revenue grew more than 300% in the first half of 2026, though exact figures were not disclosed.

Beacon's platform includes a data layer for fusing and cleaning security telemetry, an environment for building and running AI-driven security workflows, and a library of specialized security agents. Future agents will focus on shadow-AI analysis, alert triage, and investigations.

"The acceleration of AI agents in the enterprise is creating a distinct need for a legible context layer for cyber defenders," said Tal-Hochberg. "We built Beacon to provide the trusted data layer that allows organizations to deploy security agents compliantly and effectively."

Oren Yunger, managing partner at Notable Capital and a Beacon board member, added: "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. The data-trust gap is exactly what Beacon is bridging in the AI era."

This funding round follows the launch of Beacon's agentic data layer, which automates the normalization and enrichment of security data, reducing the engineering work required to prepare data for security operations.
