Beacon raises $13M to give cybersecurity agents trustworthy data

Beacon Security has raised $13M to solve a problem that could limit agentic cybersecurity: autonomous systems cannot make reliable decisions when the underlying security data is duplicated, incomplete or attached to the wrong identity.

What happened

Notable Capital led the seed round. Holly Ventures, AlphaDrive Ventures, SVCI, Jefferies Family Office and more than 60 cybersecurity founders and security executives also participated.

Beacon sits between an organisation’s raw telemetry and the analysts, security tools or AI agents that need to use it. Its platform collects information from multiple products, removes low-value duplication, resolves identities and assets, and adds context before passing the data into detection and investigation workflows.

The founding team includes Gal Tal-Hochberg, whose previous company HiredScore was acquired by Workday, alongside Or Mattatia and Iddo Israely, who bring experience across cybersecurity and large-scale data systems.

Beacon says annual recurring revenue grew by more than 300% during the first half of 2026. That figure is company-reported.

Why it matters

Security teams already struggle with fragmented data from identity systems, endpoint tools, cloud platforms and network products. Adding AI agents does not remove that fragmentation. It can make the consequences worse by allowing an incorrect conclusion to be reached and acted on faster.

Beacon is therefore targeting the foundation rather than launching another general-purpose security assistant. The product aims to make security information usable by both human analysts and specialised agents.

The bigger picture

As autonomous security tools spread, data quality and entity resolution may become as strategically important as the models themselves. Organisations will need to know which user, device and application an alert actually refers to before allowing software to respond automatically.

Beacon’s challenge is proving that customers need a separate platform rather than extending existing security data lakes or information-management systems. Its opportunity is to become the trusted orchestration layer connecting those systems to the next generation of cyber-defence agents.
