$110M Inforcer Series C Run Crowns the MSP Security Bet

$110 million in 18 months is the real story behind Inforcer’s $50 million Series C. The funding suggests investors are betting that small and medium-size businesses won’t manage the next phase of AI and security risk directly. Their managed service providers will.

London-based Inforcer announced the round Thursday, led by Insight Partners, according to TechCrunch. The company builds software that lets MSPs manage Microsoft 365 accounts for multiple SMB clients from one platform.

XOOMAR analysis: the Inforcer Series C is not just another cybersecurity raise with AI language attached. It points to a more practical shift. Security spending for smaller firms is moving toward operational infrastructure: tools that let outsourced IT providers configure, monitor, and respond across many Microsoft environments without treating every client as a one-off project.

That matters because the SMB problem is brutally simple. TechCrunch reports that most small businesses can’t afford an in-house IT department. They outsource to MSPs. AI and faster cyber threats make that outsourcing model more important, but also harder to run.

Inforcer Series C puts $50M behind the MSP layer of SMB security

Inforcer’s core product, 365 Manager, gives MSPs a single platform to manage Microsoft 365 accounts across multiple small and medium-size business customers. That sounds mundane. It’s also exactly where the pressure is building.

Smaller companies still need security controls, account governance, policy management, and threat response. They just don’t usually have the staff to keep tuning those controls as risks change. Inforcer is selling into that gap.

The company’s recent product work shows where it thinks the market is going:

• Shadow AI detection: Tools to detect when employees use unauthorized AI tools on company devices.
• Threat detection and response: A product designed to catch cybersecurity risks as they happen.
• Microsoft 365 focus: Inforcer says it will remain focused on the Microsoft suite, because so many SMBs still use it.

Jamie Daum, Inforcer’s co-founder and CEO, told TechCrunch that business has been growing 300% year-over-year. He also said the company doubled its valuation between its Series B and Series C, though he declined to share the figure.

That last detail matters less than the sequence. Three rounds in 18 months, totaling $110 million, means Inforcer is raising as if the window is open now, not later.

The 18-month funding burst: $110M raised, 300% growth, one clear thesis

Inforcer’s investors include Insight Partners, Dawn Capital, and Meritech Capital. The Series C follows earlier rounds that, together with the new financing, bring the company’s 18-month total to $110 million, according to TechCrunch.

The funding is tied to a specific operating thesis: MSPs need more infrastructure because IT has become too complex for many smaller clients to manage internally. AI sharpens that need.

William Connor, Inforcer co-founder and chief community officer, told TechCrunch that attacks now take minutes to execute rather than months to plan. Attackers are using AI to analyze what to attack and LLMs to craft more convincing phishing emails.

“For SMBs, that means facing threats that are more automated, more scalable and harder to defend against than we’ve ever seen before,” Daum added.

XOOMAR analysis: this is why the Inforcer Series C lands differently from a generic security funding announcement. The customer pain is not only detection. It’s repeatability. MSPs need to apply controls across many tenants, prove work to clients, and keep up as AI tools enter daily workflows.

That is also why this story connects to the broader AI security debate XOOMAR has tracked in pieces like Nvidia AI Security Alliance Leaves OpenAI Off Roster and Escaped AI Agent Hits Hugging Face in OpenAI Security Test. Inforcer is operating at a narrower layer: the channel tools that make AI risk manageable for SMBs using Microsoft 365.

AI turns Microsoft 365 management into a control problem for MSPs

Inforcer is staying close to Microsoft 365, rather than spreading across every productivity suite. Connor told TechCrunch that Microsoft has historically focused on platforms for larger enterprises, leaving room for specialized vendors serving smaller, more segmented customers.

“We see ourselves as complementary to Microsoft rather than competing with them,” Connor said.

That positioning is smart. It avoids a direct fight with Microsoft while giving MSPs software designed around their actual workflow: many clients, many tenants, recurring policy work, and limited time.

The AI angle is not abstract. Inforcer has already built Shadow AI detection for unauthorized AI tools on company devices. Connor also said organizations now need to plan around how they govern and protect company data, including the use of AI and agents inside businesses.

XOOMAR analysis: AI raises the cost of weak configuration. If employees connect tools without review, use unauthorized services, or expose company data through poorly governed workflows, the MSP becomes the first line of cleanup. Inforcer’s pitch is that MSPs need a shared control plane before those problems multiply across their client base.

From 365 Manager to threat detection, Inforcer is changing how it charges

Inforcer’s product shift is also changing its business model. TechCrunch reports that 365 Manager was priced per client. With the new threat-detection tool, Inforcer is moving toward a per-user model that better matches how MSPs sell these tools to customers.

Daum also said future AI products could become consumption or token-based.

XOOMAR analysis: pricing is a strategic tell. Per-client pricing fits a management console. Per-user pricing fits ongoing security coverage. Token-based pricing would fit AI features that vary by usage. That evolution suggests Inforcer wants to move from administrative tooling into a broader MSP security platform.

Investors, MSPs, SMB owners, and attackers see four different stories

For investors, Inforcer sits at the intersection of three sourced facts: SMBs outsource IT to MSPs, AI and cyber threats are making that work harder, and Inforcer says revenue growth is running at 300% year-over-year. That is a clean venture narrative.

For MSPs, the value is operational. They need tools that reduce manual work, standardize controls, and support many customers from one place. CRN’s related source material said Inforcer had grown to about 800 MSP partners from about 300 last fall, with the team expanding to 120 employees from 50.

For SMB owners, the message is uncomfortable. They are being pushed toward AI adoption while also being warned that AI tools can create governance and data protection risks. Many won’t have internal teams to sort those tradeoffs.

For attackers, Connor’s comments suggest speed is the advantage. If attacks can execute in minutes and AI improves phishing quality, smaller companies with limited security capacity become harder to defend.

Through 2026, secure defaults will matter more than AI branding

Inforcer says it plans to expand further in the U.S. It is also investing capital into product development, including Shadow AI detection and threat detection and response.

The next proof points are practical:

• Product depth: Can Inforcer move beyond Microsoft 365 account management into durable AI governance and threat response?
• MSP adoption: Can it keep growing partners without making the platform harder to operate?
• Microsoft risk: Does Microsoft leave enough room for specialized SMB-focused vendors?
• Pricing fit: Do per-user or future token-based models make MSP margins easier, or more confusing?

XOOMAR view: the winners in SMB cybersecurity won’t be the vendors with the loudest AI branding. They’ll be the ones that make secure defaults easy enough for small teams and MSPs to maintain every week. The Inforcer Series C is a bet that this control layer becomes more valuable as AI spreads through ordinary business software. The evidence to watch is whether MSPs keep standardizing around platforms like Inforcer, or whether Microsoft absorbs more of the workflow itself.

The Bottom Line

• Inforcer’s $50 million Series C signals strong investor demand for infrastructure that helps MSPs secure smaller businesses.
• SMBs often lack in-house IT teams, making outsourced security management more critical as AI and cyber risks accelerate.
• Tools like 365 Manager could make Microsoft 365 security more scalable across many small-business environments.
