Reco has raised an additional USD $55 million, with participation from AT&T Ventures, bringing the security software company's total funding to USD $140 million.
The round also includes backing from Forestay and Quadrille Capital. Reco will use the funding to expand sales, partnerships, channels and customer support as large companies broaden their use of AI agents across internal systems and business applications.
The funding comes as businesses face a growing challenge in tracking software agents that can access corporate data, applications and workflows. These tools are being deployed across collaboration platforms, browsers, copilots and automated processes, often through OAuth grants, API connections, service accounts and embedded AI features in software already used by staff.
Reco focuses on what it calls agentic security, a category aimed at helping companies understand which AI agents are active, what identities and permissions they use, what systems and data they can access and what actions they can trigger. Its software is designed to help security teams identify excessive access and remove or reduce it.
Industry forecasts cited by Reco point to a rapid rise in the number of agents used by large organisations. Gartner predicts the average global Fortune 500 enterprise will have more than 150,000 agents in use by 2028, up from fewer than 15 in 2025, according to the company.
That projected growth is contributing to investor interest in tools that govern AI use inside large organisations. Reco cited Grand View Research figures valuing the global agentic AI security market at USD $1.3 billion in 2025, with a projection that it will reach USD $17.8 billion by 2033.
AT&T backing
AT&T's involvement is notable because it is both an investor and a customer. The telecoms group said Reco gives it greater visibility into agent security risks, access management and third-party integrations across its enterprise software environment.
"As both an investor and customer, AT&T recognizes the growing importance of helping organizations understand and manage how AI agents interact with business applications and data," said Vikram Taneja, Head of AT&T Ventures. "Reco's approach to visibility and governance aligns with the needs we are seeing across enterprises as agent adoption continues to evolve."
Rich Baich, Chief Information Security Officer at AT&T, described the software's practical use inside the company.
"Reco helps AT&T strengthen governance across our enterprise apps and AI ecosystem by providing greater visibility into agent security risk, access management, and third-party integrations," said Rich Baich, Chief Information Security Officer at AT&T. "This insight enables better decision-making, improves audit readiness, and supports our commitment to securing innovation across the enterprise."
Enterprise demand
Demand is being driven by Fortune 500 companies seeking ways to manage the spread of AI agents across business ecosystems. Reco's software connects with more than 280 applications and includes integrations with providers and platforms such as OpenAI, Anthropic, Microsoft Copilot, Salesforce, ServiceNow and Workday.
Its system is built around what it calls the Reco Graph, which maps relationships between agents, identities, applications, permissions, data and workflows. The goal is to give security teams a clearer picture of how access is connected across an organisation and where risk may lie.
That matters because a single agent may appear low risk on its own while still holding connections that open paths into customer data, source code, finance systems, service tickets, documents or internal communications. In large organisations, those overlapping permissions can create a broader security issue than a conventional application review might reveal.
Ofer Klein, Chief Executive Officer and Co-Founder of Reco, said the pace of AI adoption is outstripping many companies' ability to map those connections.
"Agents are gaining access to business applications and data faster than many organizations can map or govern those connections," said Ofer Klein, Chief Executive Officer and Co-Founder of Reco. "AT&T's participation as both a customer and strategic investor reflects the need for security that follows agents across enterprise ecosystems. This funding will help Reco expand sales, partnerships and customer support as more large enterprises move agents into production."
The platform is intended to help businesses avoid choosing between restricting AI adoption altogether and accepting unmanaged exposure. It can be used to reduce excessive permissions, revoke outdated access, disable risky integrations and apply policy controls without interrupting legitimate workflows.
Reco's latest funding round underlines how quickly governance and oversight tools are becoming part of enterprise AI spending as companies move from limited trials to broader deployment of agents across their operations.
