Reco raises $55M as AI agent security demand grows
Reco, a startup focused on securing AI agents in enterprise environments, closed a $55 million funding round on September 29, 2026, with backing from AT&T Ventures, Forestay, and Quadrille Capital. The extension to the company's Series B—which raised $30 million in February 2026—brings Reco's total funding to $140 million and signals deepening investor confidence in the agentic security market.
Growing Market for Agent Risk
TechCrunch reported that the funding round reflects "rising investor interest in AI-agent security" as enterprises deploy autonomous agents across operations. Reco positioned itself as "the leader in Agentic Security," addressing a category that barely existed two years ago but has accelerated as companies move from pilot deployments to production workloads.
The influx of capital into agent security mirrors broader enterprise anxiety about autonomous systems operating with minimal human oversight. Unlike chatbots confined to conversation, agents execute actions—making purchases, transferring funds, accessing databases, managing infrastructure. Each action creates potential surface area for fraud, data leakage, or compliance violations.
How Reco Plans to Deploy Capital
Reco announced it will deploy the $55 million toward "expansion across sales, partnerships, channels and customer support," according to the company's own funding announcement. The focus signals a shift from building product to scaling go-to-market operations—a move typically made when product-market fit has stabilized and the bottleneck becomes customer acquisition and retention.
SecurityWeek noted the round arrives as startups proliferate in the agentic security space, suggesting Reco faces intensifying competition. The company's valuation—implied to have "more than doubled" since the February Series B—positions it as a market leader by valuation, though the total enterprise TAM for agent security remains unquantified.
Enterprise Adoption Patterns
AT&T Ventures' participation is notable: the telecom conglomerate typically backs infrastructure and enterprise security plays with clear pathways to internal adoption and customer bundling. This suggests Reco may be positioning agent security as a managed service that carriers and large enterprises can integrate into existing risk and compliance programs.
The funding round closes a significant capital story in the young agent economy. Unlike agent *builders* (OpenAI, Anthropic, Databricks) competing on capability and inference cost, agent *security* vendors compete on detection speed, false-positive rates, and integration breadth—more defensible moats in a crowded AI software market.
