Reco Secures $55 Million to Expand AI Agent Security Platform

AI security startup Reco has raised $55 million in new funding as enterprises deploy AI agents faster than their security teams can identify and govern them. The round brings Reco’s total capital raised to $140 million and follows a $30 million Series B announced in February.
AT&T, a Reco customer, invested through its venture arm alongside Forestay and Quadrille Capital. Reco co-founder and CEO Ofer Klein said the company’s valuation has more than doubled since the Series B, placing it in the high hundreds of millions of dollars, without disclosing a specific figure.
Security teams face an AI agent inventory problem
Reco had primarily sold software for mapping and securing SaaS and AI platforms. It is now positioning its offering as a broader agent-security platform built around a context graph that connects agents to applications, people, accounts and permissions.
The stated aim is to show security teams what an agent can reach and enable them to remove access that is not required. Klein said the shift reflects the pace at which organisations are building and deploying agents without maintaining a complete inventory.
At one Fortune 100 customer, Reco said its platform identified 21,000 agents that the company did not know about. At a large financial-services customer, the company said it found an agent created by a former employee that could access Salesforce and share data with a domain the organisation could not see.
Context and runtime visibility become central
AI agent security has become a crowded category. Vendors are addressing different parts of the problem, from checking the tools agents use and controlling data access to endpoint detection, response controls and the discovery of unauthorised AI use. Their approaches often include continuous monitoring, runtime security, tool access controls and MCP vetting.
Reco’s platform integrates with more than 280 applications, and Klein said new integrations can be added within days. For agents outside applications connected directly to the platform, Reco uses browser and network signals for discovery. It also includes controls to inspect prompts and tool calls.
The company has more than 100 customers, with financial-services organisations accounting for about 40% of its business. Klein described annual recurring revenue as being in the double-digit millions of dollars and said he expects it to triple this year.
Funding supports expansion
Reco plans to use the new capital for hiring, sales, partnerships and customer support. Its bet is that existing visibility into SaaS applications, along with the AI agents those applications increasingly provide, can differentiate it in a market with many competing agent-security claims.
For businesses, the immediate implication is practical: agent adoption should be paired with a current inventory of agents, their connected applications, permissions, tool calls and accessible data, so access can be limited before agents reach critical systems.
