inforcer raises $50M Series C to scale AI security platform for MSPs

inforcer, a UK company building security and AI management tools for managed service providers, has closed a $50 million Series C. Insight Partners led the round, with existing backers Meritech Capital and Dawn Capital chipping in too. That's a meaningful vote of confidence for a company operating in the increasingly crowded intersection of Microsoft 365 security and AI governance.

The pitch is straightforward once you unpack it. MSPs juggle security and compliance for dozens, sometimes hundreds, of small and medium-sized business clients, all running on Microsoft 365. inforcer gives them one control plane to standardize that work instead of managing it customer by customer. Over the last two years, the company says it has seen rapid global adoption as more MSPs look to consolidate their Microsoft security and AI tooling rather than stitch together separate systems.

What's notable is how much of the recent product push centers on AI specifically, not just traditional security. inforcer has added Copilot Manager, Shadow AI detection, and a Threat Detection & Response tool aimed at catching both human-driven attacks and AI-assisted ones. CEO Jamie Daum framed the urgency bluntly, pointing to tools like Anthropic's Claude Code and something called Mythos as examples of how AI is lowering the bar for both legitimate coding and malicious hacking alike.

Daum's argument is that SMBs are facing a threat environment that's never been this dangerous, and that AI is the accelerant. Whether or not that's overstated, it's clearly the thesis investors are backing here. The new capital is earmarked for expanding the platform further, building out more of those Microsoft security and AI management features, and scaling the company's operations and customer base as it tries to keep pace with demand from MSPs.
