Beacon Security raises $13 million to build AI-focused cybersecurity platform

Beacon Security, a cybersecurity startup specializing in AI-driven security operations, has secured $13 million in seed funding. The investment 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, including founders from Talon, Descope, Gem Security, Dig Security, and Cider Security.

The company, founded in 2024 by CEO Gal Tal-Hochberg (former founder of HiredScore, acquired by Workday for $520 million), Or Mattatia, and Iddo Israely, aims to build an AI-native cybersecurity platform. The platform sits between an organization’s security data sources and the tools used by analysts, normalizing, enriching, and organizing data from multiple vendors. This provides a cleaner, more reliable data foundation for both human analysts and AI agents to detect, investigate, and respond to emerging threats.

Beacon reports rapid early adoption among enterprise customers in financial services, insurance, technology, healthcare, and hospitality. The company’s annual recurring revenue grew over 300% in the first half of 2026, though specific figures were not disclosed.

The funding will be used to expand Beacon’s agentic data layer, which automates the normalization and enrichment of security data, reducing engineering overhead for security operations. Future plans include developing specialized AI agents for shadow-AI analysis, alert triage, investigations, and threat hunting.

“The acceleration of AI agents in the enterprise is creating a distinct need for a legible context layer for cyber defenders,” said CEO Gal Tal-Hochberg. “We built Beacon to solve these challenges by providing the trusted data layer that allows organizations to deploy security agents compliantly and effectively.”

Oren Yunger, managing partner at Notable Capital and Beacon board member, emphasized the data-trust gap: “Every CISO knows the real bottleneck isn’t detection; it’s trust in your own data. That problem doesn’t get easier when you add agents; it gets less forgiving. Beacon is bridging that gap in the AI era.”

The investment underscores the growing demand for AI-powered cybersecurity tools that can handle increasing alert volumes and expanding attack surfaces while ensuring data quality and reliability.
