❯ AI agent security company Reco adds $55 million as customer AT&T becomes a strategic investor

First, count the agentsReco works on agent security: helping large companies find which AI agents are running internally, under what identities, with what permissions and with access to what data. According to Pulse 2.0, its Reco Graph maps the relationships between agents and applications, data and workflows, and supports more than 280 app integrations, including OpenAI, Anthropic, Microsoft Copilot, Salesforce, ServiceNow and Workday.

Topping up after the Series BThe company’s CEO and co-founder is Ofer Klein. According to Reco’s blog, its total funding stood at $85 million after its Series B. TechCrunch describes the new money as an extension of that round.

AT&T as customer and shareholderThe round announced on September 29 totals $55 million. AT&T Ventures took part as a strategic investor, and Forestay and Quadrille Capital are new investors, bringing total funding to $140 million. AT&T is itself a Reco customer. The money will expand sales, partner channels and customer support.

More agents, messier permissionsOnce a company connects agents to systems such as Salesforce and Workday, each agent carries a set of permissions, and security teams often do not know the total. Reco cites a Grand View Research forecast that the agent security market will grow from $1.3 billion in 2025 to $17.8 billion by 2033. That is one firm’s view, but a customer as large as AT&T paying to take a stake at least shows demand has moved from trials to procurement.

▪ SIGNALCompanies are deploying agents faster than they can count them, so the first thing security vendors sell is not protection but an inventory.
