Reco, a security startup that maps and protects SaaS and AI platforms, said Tuesday it has raised $55 million in new funding, an extension of the $30 million Series B it announced in February. AT&T, already a Reco customer, participated through its venture arm, along with Forestay and Quadrille Capital. The round lifts Reco's total capital raised to $140 million.
The company has repositioned itself around a broader product that uses a context graph to link AI agents to apps, people, accounts, and permissions. That gives security teams visibility into what an agent can reach and the ability to cut off access it does not need. Reco co-founder and CEO Ofer Klein said the shift responded to companies building and deploying agents faster than they can track them.
Reco points to findings at customer deployments to illustrate the problem. At one Fortune 100 customer, Klein said, the platform discovered 21,000 agents the company did not know existed. At a large financial services customer, Reco claims it found an agent created by a former employee that could reach Salesforce and share data with a domain the company could not see.
Klein said demand for agent security now covers the entire ecosystem end-to-end rather than the agent alone. Other vendors describe similar urgency. HiddenLayer co-founder and CEO Chris Sestito said this month that once agents reach production, cost and risk scale from theoretical to full scale quickly, and that more than 50 of his customers run agents in production that touch critical systems and sensitive assets. Cymphony said it found roughly 85,000 files accessible to AI tools and agents at one U.S. public company.
Investor interest in agent security has grown crowded. Public Crunchbase and PitchBook profiles show at least two dozen companies selling some form of it, with offerings that include vetting agent tools, controlling data reach, device-level detection and response, and finding unapproved AI use. The products differ, but their promises around discovery and governance share common themes such as knowledge graphs, continuous monitoring, runtime security, tool access, and MCP vetting.
Reco is betting that its existing coverage of SaaS apps and the agents those apps now offer will distinguish it. The company integrates with more than 280 apps, and Klein said new integrations can be added within days. He said the platform uses browser and network signals to find agents outside directly connected apps and includes controls to inspect prompts and tool calls.
Klein said Reco's valuation has more than doubled since the February Series B and estimated it in the high hundreds of millions of dollars, without giving specifics. Annual recurring revenue is in the double-digit millions, he said, and he expects it to triple this year. Reco has more than 100 customers, with financial services accounting for about 40% of the business. The new funding will go toward hiring, sales, partnerships, and customer support.
