Beacon Security Raises $13 Million to Expand Agentic Cyber Defense Platform

Beacon Security has secured $13 million in seed funding led by Notable Capital, with participation from Holly Ventures, AlphaDrive Ventures, SVCI, the Jefferies Family Office, and more than 60 founders and CISOs. The company announced in a press release that the funds will support its goal to provide security teams with a trusted data layer for both human and AI agents.

Beacon’s platform enables autonomous and human security operations through an agentic structure that supports prevention, detection, and response. Its data layer integrates telemetry from multiple vendors, automates normalization, and provides context for security teams to identify threats across systems. The platform includes a library of production ready agents built to assist with investigation, posture analysis, and detection engineering.

The company reported adoption by enterprises across fintech, healthcare, and hospitality sectors, achieving more than 300 percent annual recurring revenue growth in the first half of 2026. Beacon was founded in 2024 by Gal Tal-Hochberg, Or Mattatia, and Iddo Israely, who have backgrounds in intelligence, offensive security, and large scale data infrastructure.

The latest funding follows the launch of Beacon’s agentic data layer, which automates enrichment and normalization of security data to reduce engineering workload and improve visibility. Beacon stated that its technology is already trusted by Fortune 500 organizations working in highly regulated industries.
