Reco raises $55M as AI agent security market heats up

Reco has raised $55 million to secure AI agents operating inside enterprise networks, joining a growing number of startups trying to solve what chief information security officers are calling “AI sprawl.” The round, reported by TechCrunch, comes as companies roll out large numbers of agents across internal systems, creating new risks and compliance challenges.

The funding follows several recent deals in the same area, suggesting a market that is both growing and splitting into smaller segments. Island raised $400 million just days ago at a $6.4 billion valuation, while Outerlimit, Rig Security, and Kontext have all secured funding in the last month to address different parts of the same problem: stopping AI agents from acting unpredictably, leaking data, or being taken over. AIR, another startup in this group, raised an undisclosed amount earlier in September to track agent behavior.

Reco’s approach focuses on runtime enforcement, stepping in to block unauthorized actions as they happen. This differs from competitors that rely on after-the-fact audits or decentralized security layers. The distinction could matter to enterprises tired of adding more monitoring tools to their existing setups. But it remains to be seen whether runtime enforcement alone will be enough to justify Reco’s valuation, especially as larger players like Island expand into similar areas with browser-level controls.

The timing of these rounds reflects a shift in how enterprises adopt AI. Early deployments were experimental, but as agents move from pilot projects to full use, security teams are rushing to add governance to systems that weren’t built for it. The result is a group of startups each targeting a specific angle—identity security, decentralized risk prevention, browser isolation—to avoid direct competition. It’s unclear whether these specialized approaches can support standalone businesses; consolidation may be coming, especially if investors start favoring scale over niche focus.

For now, Reco’s $55 million suggests confidence in its approach. But with Island’s massive round setting a new standard, smaller players face pressure to prove they can outpace not just cyber threats, but each other. The next few quarters will show whether this market values deep specialization or broader solutions—and whether CISOs will prefer multiple tools or a single, integrated platform. Either way, treating AI agents as a security afterthought is no longer an option.
