Overmind raises €2.3 million to secure AI agents
Former MI5 officer turned entrepreneur has raised €2.3 million in seed funding for Overmind, a security startup focused on protecting AI agents and autonomous software systems. The round underscores growing investor concern that the rapid deployment of artificial intelligence is outpacing traditional cybersecurity tools and policies.
A new security layer for autonomous AI
Overmind is building a dedicated security platform for organisations deploying autonomous agents, such as code-writing bots, workflow orchestrators and AI-driven decision tools. Instead of defending only networks or endpoints, the company focuses on monitoring and controlling what AI agents can access, change and trigger inside corporate systems.
The platform is designed to detect abnormal behaviour, prevent data exfiltration and block malicious prompts or instructions that could cause agents to act against business or regulatory rules. With enterprises increasingly integrating large language models into core processes, the startup positions itself as a critical safeguard against misconfigurations, abuse and supply‑chain style attacks on AI infrastructure.
Intelligence background shapes threat model
Drawing on experience from the UK’s domestic intelligence service, the former MI5 officer behind Overmind applies national‑security style threat modelling to commercial AI deployments. The company treats AI agents as both powerful assets and potential insider threats, requiring granular access control, continuous monitoring and clear audit trails.
This intelligence-led approach is aimed at sectors such as financial services, critical infrastructure, and technology companies that are early adopters of AI automation but face strict compliance and risk requirements.
Rising demand for AI-native security
Investors are betting that AI-specific security will become a core layer of the enterprise stack, comparable to identity management and cloud security. As regulators in Europe and beyond introduce new frameworks for trustworthy AI, tools that can demonstrate control, explainability and resilience of AI systems are expected to see accelerated demand.
With fresh capital, Overmind plans to expand its engineering team, deepen integrations with leading AI platforms and run pilot projects with large enterprises seeking to deploy autonomous agents safely at scale.
