How to Choose the Right MDR Provider for Your MSP or IT Team
By N‑able
Ransomware doesn’t wait for you to staff a 24/7 SOC. With ransomware now present in 44% of breaches and exploitation timelines shrinking to days, the window between vulnerability disclosure and attack has never been smaller (Verizon DBIR 2025).
For MSPs managing dozens of client environments and corporate IT teams stretched thin, Managed Detection and Response (MDR) represents the difference between containing threats in minutes versus discovering breaches months later. The challenge: distinguishing genuine MDR providers who actively hunt and contain threats from vendors repackaging basic monitoring tools under the MDR label.
This guide breaks down the criteria that separate real TDIR (threat detection, investigation, and response) capabilities from marketing hype, the essential questions that reveal true operational delivery, and how to evaluate providers based on your specific operational needs.
MDR Basics: Service Model vs. Technology Platform
MDR delivers remote SOC functions: threat detection, investigation, and response. The critical distinction is active threat containment by the provider rather than passive monitoring.
Legacy MSSPs monitor and alert; your team responds. MDR providers investigate alerts and execute containment on your behalf while you maintain visibility.
MDR Coverage Types: MEDR, MNDR, and MXDR
MDR services differ in scope and data sources. Managed Endpoint Detection and Response (MEDR) focuses exclusively on endpoint telemetry, providing deep visibility into workstation and server activity. Managed Network Detection and Response (MNDR) monitors network traffic patterns and east-west movement to catch threats that bypass endpoint agents. Managed Extended Detection and Response (MXDR) correlates signals across endpoints, network, cloud, identity, and email for unified threat visibility. Most MSPs and mid-market IT teams benefit from MXDR’s broader coverage, though MEDR may suffice for organizations with mature network security infrastructure already in place.
Why MDR Matters for MSPs and IT Teams
The Capacity Math Doesn’t Work
SOCs face overwhelming alert volumes, and the backlog is mathematically impossible to clear with manual processes alone. The cybersecurity industry faces a 4.8 million professional workforce gap, with 67% of organizations reporting staffing shortages (ISC2 2024). Alert investigations require significant analyst time, guaranteeing most threats slip through unexamined without automation assistance.
The Economics Create Undeniable ROI
Here’s the thing: the average data breach now costs $4.88 million, while organizations with security staffing shortages face $1.76 million in additional breach costs (IBM 2024). Organizations using AI and automation extensively in security operations save $2.2 million per breach. MDR services achieve faster mean time to detect compared to SOC-only operations, translating to significant cost savings per incident.
Zero-Day Reality Changed Threat Timelines
The gap between vulnerability disclosure and mass exploitation continues to shrink while median remediation timelines remain measured in weeks. CISA’s Known Exploited Vulnerabilities catalog grew 20% in 2025, with federal agencies now required to remediate critical vulnerabilities within 15 days. This gap is impossible to close without continuous automated monitoring backed by expert analysis.
Bottom line: manual-only security operations accept extended breach detection timelines and substantial preventable costs.
Key Criteria for MDR Providers
Not all MDR is created equal. These deal-breakers separate real TDIR capabilities from repackaged monitoring.
Human-Driven Detection vs. Technology-First Offerings
The distinction: genuine human-driven MDR with complete TDIR capabilities versus repackaged monitoring tools. Quality MDR uses AI to augment analyst capabilities rather than replace human expertise. MDR’s key value proposition is the human interpretation of security incidents, not autonomous AI decision-making.
Turnkey TDIR Capabilities with Defined Response Boundaries
Real MDR providers deliver turnkey TDIR:
- Detection rules already tuned for your environment
- Investigation procedures that don’t require your input
- Response playbooks they execute without waiting for your approval
Here’s what accountability actually looks like: “What response types are provided as a component of the MDR service, and what is the limit of those response activities?” This forces vendors to specify exactly where their responsibility ends, revealing whether you’re buying alert notification, guided remediation where you execute their recommendations, or automated response where they execute containment actions.
Monitoring Coverage Beyond Endpoints
What this looks like in practice: providers must extend beyond network and endpoint monitoring:
- Hunt for exposed credentials in identity systems
- Scan SaaS misconfigurations
- Correlate cloud infrastructure vulnerabilities with threat intelligence
MDR providers increasingly focus on threat exposures rather than reactive detection alone.
Performance Metrics with Financial Accountability
Demand actual performance data, not just SLA commitments. Strong providers specify:
- Critical alerts triaged within 15 minutes
- Investigations within 30 minutes
- Containment within two hours
- Meaningful service credits for breaches
Top-tier MDR providers maintain high SLA compliance rates verified through transparent dashboards.
Transparent Service Portal and Compliance Alignment
Industry analysts formally score providers on portal capabilities including real-time incident status visibility, historical trend analysis, and persona-based information organization. For MSPs, customizable reporting for client-facing deliverables is critical. For corporate IT teams, executive-ready dashboards that translate security metrics into business impact matter most.
Providers must demonstrate verifiable compliance beyond marketing claims. For healthcare-focused organizations, HITRUST CSF certification consolidates HIPAA, NIST, and ISO controls.
Request actual SOC 2 Type II attestation reports; SOC 2 Type II demonstrates controls operating effectively over time rather than point-in-time compliance like Type I.
10 Essential Questions to Ask MDR Vendors
Here’s how to cut through vendor marketing claims. These questions distinguish genuine capabilities from promotional messaging and reveal operational delivery.
Detection Engineering and Technology Stack
1. What data sources and telemetry does your MDR service monitor across endpoints, networks, cloud, and identity systems? Demand exact log sources, not vague assurances.
2. How do you develop and maintain detection rules: vendor-supplied signatures only, or custom detection engineering? This distinguishes mature programs from signature-only approaches.
3. What is your approach to reducing false positives while maintaining detection efficacy? Request specific false positive rates and tuning methodologies.
4. What security technologies form your MDR platform (EDR, NDR, SIEM, XDR) and how does your service integrate with existing security infrastructure? This prevents vendor lock-in.
Operational Delivery and Team Expertise
5. What is your mean time to detect (MTTD) and mean time to respond (MTTR) with actual performance data? Quality MDR providers achieve significantly faster detection compared to SOC-only operations.
6. Do you provide 24/7/365 coverage across regional SOCs, or single-location teams working overnight shifts? This reveals true operational capacity.
7. What are the qualifications, certifications, and experience levels of your security analysts?
Service Level Agreements, Reporting, and Accountability
8. What are your SLAs for alert triage, investigation initiation, and incident containment by severity level, what happens when SLAs are missed, and what reporting do you provide? Strong providers offer meaningful service credits for missed SLAs.
Compliance and Risk Assessment
9. What security certifications do you maintain (SOC 2 Type II, ISO 27001) and can you provide actual attestation reports for verification? Request actual attestation reports.
Data Retention and Threat Hunting
10. How long do you retain security telemetry and log data for threat hunting and forensic investigation? Providers analyzing 30 days of data miss persistent threats that quality threat hunting uncovers. Look for minimum 90-day retention with options for one-year historical analysis; this enables detection of advanced persistent threats and supports post-incident forensic investigations.

Making the MDR Decision
The decision comes down to operational capacity, not technology. If you have 24/7 analyst coverage in-house, you can run EDR/XDR platforms directly. If you don’t, you need MDR.
For MSPs, prioritize tool flexibility, analyst-to-client ratios, ticketing integration, and contract terms that let you add or remove client sites without penalty.
For corporate IT teams, focus on integration with existing infrastructure, compliance reporting for your industry, and executive dashboards that translate security metrics for board conversations.
Bottom line: exploitation timelines keep shrinking, ransomware keeps showing up in breaches, and alert backlogs keep growing. MDR delivers enterprise-grade protection without enterprise-level headcount.

Frequently Asked Questions
What’s the difference between MDR and traditional managed security services?
Traditional MSSPs monitor security infrastructure and send alerts to customer teams who investigate and respond. MDR providers actively investigate alerts and execute containment actions, taking ownership of complete threat detection, investigation, and response rather than notification.
How much does MDR typically cost compared to building an internal SOC?
Internal security operations face significant skills shortage cost penalties, while MSSP/MDR partnerships reduce breach costs substantially, creating meaningful cost differentials favoring MDR services.
What mean time to detect should I expect from a quality MDR provider?
Quality MDR providers achieve significantly faster mean time to detect compared to SOC-only operations. Providers should commit to specific detection timelines in SLAs with historical performance data demonstrating consistent achievement.
Can MDR providers work with my existing security tools or do they require their own platform?
Quality MDR providers support Open XDR integration with diverse security tools including existing EDR, SIEM, and network monitoring platforms. Providers should support Open XDR to use advanced security technologies and more effectively detect and respond to threats with automated response action triggering and 24/7 security monitoring with advanced threat analytics.
How do I verify a provider offers genuine MDR versus repackaged EDR?
Ask: “What response types are provided as a component of the MDR service, and what is the limit of those response activities?” This forces vendors to specify where their responsibility ends, revealing whether you’re buying alert notification, guided remediation where you execute recommendations, or automated response where they execute containment actions.
