inforcer Series C raises $50M for MSP security platform

inforcer has raised a $50 million Series C to expand its Microsoft security and AI management platform for managed service providers, the UK-based company announced. Insight Partners led the round, with existing backers Meritech Capital and Dawn Capital also participating.

The company did not disclose its valuation, revenue, headcount or customer count. It said the capital will go toward further product development and expansion of its operations and customer base.

The round is a growth-stage bet on a specific part of the security market: MSPs that manage Microsoft 365 environments for small and medium-sized businesses. For those providers, inforcer is pitching a single control plane to manage Microsoft security, compliance and AI services across multiple customers, rather than handling each customer environment separately.

What does inforcer do for MSPs?

inforcer builds software that lets managed service providers configure and oversee Microsoft 365 security, compliance and AI services for many SMB customers from one platform. The company says that helps MSPs standardise deployments and package security and AI services for clients that often lack large internal IT teams.

The company has added products including Copilot Manager, Shadow AI detection and Threat Detection & Response. According to inforcer, those tools are intended to help MSPs spot and respond to human and AI-assisted cyber threats while also managing how AI services are rolled out and governed.

CEO Jamie Daum said AI tools are changing the risk profile for SMBs, citing Anthropic’s Claude Code and Mythos as examples of technology that can reduce the skill needed to code or attack systems. He said the new funding would help inforcer broaden its platform so MSPs can better protect SMB customers from more sophisticated threats, especially those amplified by AI.

The claim reflects a broader vendor push to attach AI governance and AI-assisted threat detection to existing security workflows. inforcer’s positioning is narrower than a general cybersecurity platform: it is focused on MSPs standardising Microsoft security and AI management across customer portfolios.

Who invested in the round?

Insight Partners led the Series C, while Meritech Capital and Dawn Capital followed on from earlier investments. A Series C is usually a later private financing round used to scale sales, product and operations after a company has shown demand, though terms vary by company and market.

inforcer said it has seen rapid global adoption over the past two years, driven by MSP demand to consolidate Microsoft security and AI management. The company did not provide figures to support that adoption claim.

The next test is whether inforcer can turn that MSP demand into durable distribution. Security vendors are rushing to repackage AI governance, shadow AI monitoring and AI-assisted threat response, and Microsoft-focused MSPs are a logical channel for SMB buyers. The $50 million raise gives inforcer more room to build for that channel, but the company has not disclosed the operating metrics needed to benchmark the round against peers.
