Choosing an MDR partner is a high-stakes decision. For lean security teams, the right provider needs to do more than detect threats; it needs to strengthen resilience, reduce operational burden and help the organisation get more value from the security technology it already has.

That makes independent market analysis useful, particularly in an MDR landscape where providers can sound increasingly similar on paper.

In its new report, IDC MarketScape: Worldwide Managed Detection and Response Service for Midmarket 2026 Vendor Assessment, IDC says the MDR market is “undergoing a structural transformation that goes well beyond incremental capability improvements”.

Against that backdrop, IDC has assessed 20 providers specifically against the needs of mid-market organisations, evaluating both current capabilities and future strategy. Quorum Cyber has been positioned as a Major Player.

For customers, the significance is not simply the recognition itself, It is what sits behind it: deep Microsoft security expertise, integrated incident response, proactive exposure management, faster containment, and investment in securing the next generation of AI-enabled environments.

Choosing a partner with deep Microsoft expertise helps organisations get more value from the security investments they have already made, rather than adding more tools and complexity. Quorum Cyber integrates and optimises capabilities across Sentinel, Defender, Purview, Entra and Security Copilot to improve visibility, detection and response while reducing total cost of ownership.

With Quorum Cyber’s managed security services, customers receive 24/7 monitoring and detection integrated with incident response and threat hunting. In the event that an organisation needs to negotiate with cybercriminals during a crisis, our experienced Digital Forensics and Incident Response (DFIR) team can provide specialist support.

Moving beyond detection to measurable risk reduction

For years, we’ve helped organisations in the private, public and not-for-profit sectors reduce cyber risk by combining a threat-led approach with Microsoft’s security ecosystem, managed detection and response, and continuous optimisation. Our services bring together capabilities across Sentinel, Defender, Purview and Security Copilot to give customers a clearer view of their security posture and prioritise the actions that matter most.

We help organisations change the conversation from “What threats did we detect?” to “Where is our greatest risk, what action should we take, and how much have we reduced it?”

Crucially, we can demonstrate that reduction through measurable risk reduction. Customers have consolidated and displaced competing security tools, reduced total cost of ownership, accelerated incident response, and strengthened regulatory compliance.

The emerging AI security challenge

As more organisations race to deploy AI agents to conduct all manner of tasks, the AI itself needs to be safeguarded from cyber-attacks. In our view, without cyber security there is no AI.

As adoption of Microsoft 365 Copilot, Copilot Studio, and custom AI agents accelerates, organisations need greater visibility, oversight, and control.

Without a robust governance framework, it can be difficult to understand which agents exist, who owns them, what data they can access, and whether they meet business, security, and compliance requirements. As the agent landscape expands, so does the risk of unmanaged deployments, inconsistent controls, and unintended data exposure.

That’s why we’ve developed the Agent 365 Readiness Accelerator to help organisations move from AI experimentation to effective agent governance. By establishing visibility, clear ownership, lifecycle management, and operational controls, we create the foundations needed to scale AI agents securely, compliantly, and with confidence.

Organisations in any sector can gain a complete view of their AI agent landscape, reduce the risks associated with unmanaged or orphaned agents, and establish the governance framework required to deploy Microsoft 365 Copilot, Copilot Studio, and agentic AI securely across their enterprise.

As IDC explains, “A strategically notable capability within Quorum Cyber’s MDR portfolio is Agent 365, an MDR service component that extends monitoring into Microsoft Agentic AI infrastructure, providing security posture management for AI agents deployed within customer Microsoft environments.”
