Inforcer Raises $50M Series C to Arm MSPs Against AI-Era Security Threats

Inforcer, a London based company that builds security and AI management software for managed service providers, has closed a 50 million dollar Series C round led by Insight Partners, with existing backers Meritech Capital and Dawn Capital also participating.

The raise brings Inforcer's total funding to 110 million dollars across three rounds completed within just 18 months, a pace that reflects both rapid product expansion and growing investor appetite for tools that help small and medium sized businesses manage increasingly complex security and AI requirements without an in house IT team.

Most small businesses cannot justify hiring a dedicated security staff, so they outsource that responsibility to managed service providers, commonly known as MSPs. Inforcer builds the software those MSPs rely on to manage Microsoft 365 accounts for all of their small business clients from a single control plane, allowing them to standardize deployments, enforce security policy, and deliver services consistently across dozens or hundreds of customer environments at once.

Led by chief executive Jamie Daum, the company describes its platform as a scalable, multi‑tenant system that lets MSPs consolidate, standardize, secure, and monetize Microsoft 365 and AI services at scale. Recent additions to that platform include Copilot Manager, a tool for overseeing how Microsoft's AI assistant is deployed and governed across client organizations, along with Shadow AI detection and a Threat Detection and Response module the company calls Inforcer TDR.

Shadow AI detection in particular addresses a problem that has become increasingly common as employees at small businesses adopt AI tools on their own, often without their employer's knowledge or approval. Inforcer's tooling is designed to help MSPs identify when unauthorized AI applications are being used inside a client's environment and respond before that unmonitored use turns into a security or compliance issue, whether the underlying threat comes from a human actor or an AI assisted one.

The company frames its growth within a broader shift in how small businesses are approaching technology risk. As AI adoption accelerates and cyber threats grow more sophisticated, running IT and security in house has become increasingly complicated even for organizations that previously managed with minimal support. That complexity is pushing more companies toward MSPs, which in turn need more capable infrastructure themselves to manage a growing number of clients while keeping pace with how quickly the underlying technology stack is changing.

Inforcer plans to use the new funding to expand further into the United States, building on a customer base that Daum has said already spans more than 800 organizations across the US, EMEA, and Asia Pacific regions as of its most recent funding milestone. The company maintains offices across the US, UK, Netherlands, Denmark, and Australia and has grown its team past 100 employees.

Alongside the new capital, Inforcer is adjusting how it prices its products. Its original 365 Manager tool was priced per client, but the newer threat detection product is moving toward a per user model that the company says better reflects how MSPs actually sell these services to their own small business customers. Daum has indicated that future products could shift further still, potentially adopting consumption or token based pricing as the platform leans more heavily into AI capabilities.

On the question of competition from Microsoft itself, Inforcer executives have expressed relatively little concern. The company's view is that Microsoft has historically focused its own tooling on large enterprise customers, leaving a gap for specialized vendors that build purpose made products for the small and medium business segment MSPs primarily serve. That focus on staying within the Microsoft ecosystem, rather than expanding into other platforms, has been a deliberate choice for Inforcer even as its feature set grows more sophisticated.

The company's rapid funding pace mirrors its reported growth, with Inforcer citing 300 percent year over year expansion since its 2023 founding. Inforcer previously raised 35 million dollars in a Series B round in mid 2025 led by Dawn Capital, which itself came just months after a 19 million dollar Series A completed in autumn 2024 led by Meritech Capital, an investor with a track record backing companies including Salesforce, Meta, Huntress, Rewst, and Datadog.

Taken together, the succession of raises points to a company scaling quickly to meet demand in a category that sits at an increasingly important intersection: MSPs are becoming the practical enforcement layer for AI usage policy across a long tail of small businesses that will never build that capability themselves, and Inforcer is betting that owning the Microsoft 365 control plane at that layer gives it a durable head start before larger platforms move to absorb the category.
