Ransomware, identity-based attacks and persistent intrusions don’t slow down when your team is stretched thin. The average organization takes weeks to detect a breach — and that window costs money, data and customer trust. Managed detection and response (MDR) is designed to close that gap, putting experienced analysts and proven technology between attackers and the environments they’re targeting, around the clock.

The MDR market in 2026 is not short on options. From enterprise platforms backed by breach warranties worth millions to lean SMB-focused services that deploy in under an hour, the range is wide and the marketing claims frequently sound identical. Choosing well requires understanding what a given service actually does, who it was built for and whether its response model fits how your team operates.

According to the Kaseya 2026 State of the MSP Report, 71% of MSPs report year-over-year revenue growth in cybersecurity services, while 39% say hiring skilled security staff is getting harder each year. For most organizations, MDR isn’t just a security decision. It’s a business model decision.

This list is built around the operating reality most organizations face: MSPs managing security across multiple client environments, IT teams without dedicated security staff and SMBs that need enterprise-grade protection without enterprise-grade headcount. The enterprise-tier providers are evaluated honestly and represented on their merits, but the ranking reflects what delivers the most value for lean security operations.

What to look for in an MDR provider

Not all MDR services work the same way. Before evaluating specific providers, these are the criteria that separate genuinely effective services from those that produce alerts without closing the loop:

Active response, not just detection: “Response” should mean analysts take containment action on your behalf, including isolating compromised endpoints, disabling accounts and blocking malicious connections, without requiring your team to act first. Many services alert and call it response. The distinction matters most at 2 AM.
Coverage across the full attack surface: Endpoint-only MDR misses a large share of modern attacks. The strongest services ingest telemetry from endpoints, Microsoft 365, cloud workloads, firewalls and identity systems, correlating signals to surface multistage attacks no single tool would flag.
AI triage plus human investigation: Automation handles volume. Human analysts handle ambiguity. A service that relies entirely on automation misses sophisticated threats. A service that relies entirely on analysts doesn’t scale. Evaluate both layers.
Fast deployment: For organizations without a dedicated security team, time to coverage is a real metric. Two months spent onboarding is two months of exposure. Purpose-built SMB and MSP services can typically go live in days.
MSP-ready architecture: Multitenant support, PSA integration and per-client reporting aren’t optional for MSPs. A service designed for single-tenant enterprise deployments won’t operate efficiently across a portfolio of 50 client environments.
Predictable pricing: Variable data-ingestion pricing scales unexpectedly as environments grow. Per-endpoint or per-user models map more cleanly to how MSPs bill clients and how SMBs budget.

The top 10 MDR providers in 2026

Each provider below is evaluated on response depth, coverage breadth, deployment model, MSP suitability and fit across SMB and mid-market environments.

1. Kaseya MDR

Best for: MSPs and IT teams that need effective 24/7 managed detection and response with direct PSA and RMM integration, without requiring dedicated in-house security staff.

Kaseya MDR was rebuilt for the 2026 launch as an AI-powered detection and response platform with a redesigned interface, stronger event correlation, and improved signal quality. Coverage spans endpoints (Windows, macOS, and Linux), Microsoft 365 and Microsoft Entra ID, and firewalls and network components for lateral movement detection. The platform operates a SOC 2 and HIPAA-certified managed SOC staffed by security analysts who proactively hunt for threats, investigate and triage detected activity, and work directly with customer teams on remediation.

The operational advantage for MSPs is integration depth. Kaseya MDR connects natively with Autotask PSA, Kaseya BMS, Datto RMM and Kaseya VSA, surfacing actionable tickets directly into existing workflows rather than requiring a separate security console. AI-driven triage cuts through alert noise so analysts act on confirmed threats rather than sorting false positives. For organizations that also need compliance-grade log retention, Kaseya SIEM extends coverage in the same environment.

Key MDR capabilities:

24/7 managed SOC with SOC 2 and HIPAA-certified operations
Coverage across endpoints, Microsoft 365, Entra ID and firewalls
AI-powered triage and event correlation for noise reduction
Native PSA integration with Autotask and Kaseya BMS; RMM deployment via Datto RMM and Kaseya VSA
Proactive threat hunting and human-led incident investigation
Cloud-based deployment with no on-premises hardware required

Limitation to note: Kaseya MDR is purpose-built for MSP and SMB environments. Organizations with large, dedicated SOCs that need deep custom detection engineering or bespoke legacy infrastructure integration will find the enterprise-tier platforms below offer a higher ceiling.

2. CrowdStrike Falcon Complete Next-Gen MDR

Best for: Enterprises and regulated organizations that need deep threat intelligence, AI-accelerated investigation and a breach warranty backing every engagement.

CrowdStrike Falcon Complete is one of the most widely recognized MDR benchmarks in enterprise security evaluations. Built on the Falcon platform’s AI-native detection engine, the Threat Graph processes trillions of security events weekly across CrowdStrike’s global customer base, giving analysts threat intelligence depth that few providers match. Falcon OverWatch provides continuous proactive threat hunting, and the Falcon Complete team handles full-cycle remediation including system isolation, persistence removal, and environment restoration. The service is backed by a ransomware warranty up to $2 million, verified against CrowdStrike’s published warranty terms.

Key MDR capabilities:

AI-native detection via Threat Graph with cross-domain telemetry across endpoint, cloud and identity
24/7 Falcon OverWatch proactive threat hunting
Full-cycle remediation including system isolation, persistence removal and environment restoration
Agentic MDR with automated response playbooks at machine speed
Ransomware warranty coverage up to $2 million (AIG-backed)

Limitation to note: Enterprise pricing and operational complexity make Falcon Complete significantly less accessible for SMBs and MSPs. Policy configuration requires experienced security staff. Organizations not already on the CrowdStrike platform face meaningful onboarding investment.

3. Arctic Wolf MDR

Best for: Mid-market organizations without a dedicated internal SOC that want a named security team, an ongoing security partnership and comprehensive coverage without replacing existing tools.

Arctic Wolf earned a 2026 Gartner Peer Insights Customers’ Choice designation for MDR. Its Aurora open XDR platform ingests telemetry from over 200 integrations, monitoring whatever tools customers already have and adding a 24/7 SOC on top. Each customer gets a named Concierge Security Team that conducts regular security posture reviews and builds a structured Security Journey toward stronger defenses over time. In early 2025, Arctic Wolf acquired BlackBerry’s Cylance endpoint technology, extending its native endpoint detection capability. The service includes a breach warranty up to $3 million for qualifying bundles.

Key MDR capabilities:

Aurora open XDR platform with 200+ integrations across existing security tools
Dedicated Concierge Security Team with scheduled security posture reviews
24/7 SOC monitoring across endpoint, network and cloud
Cloud detection and response for AWS, Azure and GCP
Breach warranty of up to $3 million for qualifying bundles

Limitation to note: Arctic Wolf’s concierge model means the SOC primarily advises rather than taking direct hands-on remediation. Organizations that want fully autonomous containment without internal involvement may find the guided-operations model requires more participation than expected. Starting price around $44,000 per year makes it better suited to mid-market than SMB.

4. SentinelOne Vigilance Respond

Best for: Organizations standardized on SentinelOne that want platform-native MDR built on the same AI engine and telemetry their team already uses.

SentinelOne Vigilance Respond runs natively on the Singularity platform, providing tighter integration between detection telemetry and analyst response than overlaid services typically achieve. SentinelOne achieved 100% detection with 88% fewer alerts than the median vendor in the 2024 MITRE ATT&CK Enterprise Evaluation, giving analysts a cleaner signal to work from. Storyline technology automatically chains related events into a visual attack narrative for faster investigation, and automated remediation with rollback is available for endpoint threats.

Key MDR capabilities:

Platform-native MDR built on SentinelOne Singularity with full EDR and XDR telemetry
Storyline technology for automated attack chain visualization
100% detection rate in 2024 MITRE ATT&CK Enterprise Evaluation
Automated remediation with file rollback for endpoint threats
24/7 SOC coverage across endpoints, cloud, and identity

Limitation to note: Most effective for organizations already committed to the SentinelOne platform. In mixed-EDR environments, the native integration advantage disappears. Pricing scales with Singularity licensing and can become expensive at mid-market scale.

5. Huntress

Best for: SMBs and MSPs that need effective, human-verified MDR at a price point that works for small and mid-market environments, with transparent per-seat pricing and fast deployment.

Huntress was built by former NSA operators specifically for the MSP channel and SMB market. Analysts investigate every alert before it reaches the customer, escalating less than 1% of events as genuine incidents, which produces a sub-1% false positive rate and a reported mean time to remediation of around 8 minutes for endpoint threats. The platform covers Managed EDR, Managed ITDR for Microsoft 365 identity threats (with approximately 3-minute MTTR), Managed SIEM, and security awareness training. Partner pricing runs around $2.50 to $3.50 per endpoint per month for MSPs. Deployment takes under 30 minutes.

Key MDR capabilities:

24/7 SOC with human-verified triage; less than 1% of events escalated as genuine incidents
Managed ITDR for Microsoft 365 with approximately 3-minute MTTR for identity threats
Ransomware canaries for early-warning encryption detection
Multi-tenant architecture purpose-built for MSP delivery
Transparent published per-seat pricing; monthly contracts available

Limitation to note: Huntress is a managed service, not a self-service platform. Teams that want direct control over detection rules or raw log access will find the managed-only model limiting. No formal breach warranty. Less suited to environments with heavy cloud telemetry requirements or complex enterprise infrastructure.

6. Sophos MDR

Best for: SMBs and mid-market organizations that want flexible response options, cross-platform compatibility, and a choice between MDR coverage levels to match different budgets.

Sophos MDR is one of the largest independent MDR services by customer count, with 24/7 coverage delivered through a global analyst network. The service can run on Sophos’ own endpoint stack or ingest telemetry from third-party tools including CrowdStrike, Microsoft Defender, and SentinelOne. Two response tiers offer meaningful choice: MDR Essentials focuses on guidance and notification, while MDR Complete includes active containment and remediation by Sophos analysts. The service integrates with Datto RMM, Kaseya VSA and ConnectWise for MSP delivery.

Key MDR capabilities:

24/7 SOC with global analyst coverage
Compatible with Sophos native stack and third-party tools including CrowdStrike, Defender, and SentinelOne
MDR Essentials (guidance) and MDR Complete (active containment) tiers
Integration with Datto RMM, Kaseya VSA and ConnectWise for MSP delivery

Limitation to note: MDR Essentials is notification and guidance, not active response. Organizations should verify which tier they’re buying. Full active containment requires MDR Complete, priced accordingly.

7. Expel

Best for: Security-mature organizations with existing tool investments that want full operational transparency, EDR-agnostic coverage, and configurable auto-remediation with complete visibility into every analyst action.

Expel was named a Leader in the Forrester Wave for MDR Services Q1 2025, achieving 5 out of 5 scores in 15 of 21 criteria including cloud detection, identity coverage and metrics. The defining characteristic is transparency. Expel’s Workbench platform gives customers full real-time visibility into every analyst action, producing a different kind of trust than opaque managed services deliver. The service doesn’t require replacing existing tools, working across 130+ integrations covering endpoint, cloud (AWS, Azure, GCP, Kubernetes), SaaS, identity, email, and network. Reported MTTR for critical incidents is around 17 minutes.

Key MDR capabilities:

100% transparency via Expel Workbench with full visibility into every analyst action
Approximately 17-minute MTTR for critical incidents
Forrester Wave Leader in MDR Services Q1 2025, 5/5 in 15 of 21 criteria
130+ native integrations; works with existing tools without platform replacement
Configurable auto-remediation including endpoint isolation, account disable and cloud resource shutdown

Limitation to note: Expel’s transparency model requires customer engagement to fully exploit. Organizations that want to hand off security operations entirely may find the visibility more overhead than benefit. Incident response is not included in base MDR and is handled separately.

8. Red Canary

Best for: Security teams with strong detection engineering culture that want EDR-agnostic MDR, deep endpoint expertise, and a collaborative partner model with full visibility into how detections work.

Red Canary is vendor-agnostic, working with CrowdStrike Falcon, Microsoft Defender for Endpoint, SentinelOne, VMware Carbon Black and other major platforms. Detection-as-code workflows let customers see how detections work and contribute to detection logic. The platform reports a true positive rate of more than 99% and provides MITRE ATT&CK coverage visualization directly within the customer portal, giving security teams genuine visibility into their detection posture. Red Canary was named a Forrester Wave Leader for MDR Services in both Q1 2025 and Q2 2023.

Key MDR capabilities:

EDR-agnostic MDR with deep support for CrowdStrike, Microsoft Defender, SentinelOne, and VMware Carbon Black
99-plus percent true positive rate with detection-as-code transparency
ATT&CK coverage visualization showing active and gap detections per environment
Coverage across endpoint, identity, cloud, and SaaS

Limitation to note: Red Canary’s collaborative model requires more internal security knowledge than a pure managed handoff. Teams wanting end-to-end response with minimal involvement may find the partnership model demanding. Custom enterprise pricing places it in a similar tier to Expel.

9. Rapid7 Managed Threat Complete

Best for: Organizations that want MDR coverage paired with built-in vulnerability management and exposure intelligence, giving a more complete picture of risk than endpoint-only services provide.

Rapid7 Managed Threat Complete differentiates by combining MDR with proactive exposure management in a single service. Vulnerability context flows directly into active investigations, so analysts know which unpatched exposures an attacker could leverage next. Coverage spans endpoint, cloud, identity, email, and network through native multi-vector telemetry and third-party data ingestion, including CrowdStrike Falcon, SentinelOne, and Microsoft Defender. Pricing is endpoint-based rather than data-volume-based, avoiding the cost unpredictability that log-based pricing creates. The Managed Threat Complete Ultimate tier includes a $1 million breach protection warranty.

Key MDR capabilities:

MDR and unlimited vulnerability management in a single subscription
Vulnerability and exposure context integrated directly into active investigations
Native multi-vector telemetry across endpoint, cloud, identity, email and network
Endpoint-based pricing rather than data-ingestion pricing
$1 million breach protection warranty on Ultimate tier

Limitation to note: The value proposition is strongest for organizations that want both MDR and vulnerability management from one provider. Teams with existing vulnerability management already in place may find the bundle includes more than they need.

10. Cynet 360

Best for: SMBs and lean security teams that want maximum coverage from a single platform, with MDR included at no additional cost alongside EDR, network detection, identity analytics, and deception technology.

Cynet takes a different approach from the rest of this list. Rather than offering MDR as a service layered on top of other products, Cynet bundles its CyOps 24/7 MDR service into the platform at no additional cost, alongside next-generation AV, EDR, network detection and response, user and entity behavior analytics, deception technology, and SOAR in a single lightweight agent. The CyOps team has delivered 100% detection with zero false positives across three consecutive MITRE ATT&CK Enterprise Evaluations. Transparent published per-endpoint pricing is rare in this market and useful for SMBs trying to budget without entering a sales cycle.

Key MDR capabilities:

CyOps 24/7 MDR service included in the platform subscription at no additional cost
EDR, NGAV, NDR, UEBA, deception technology and SOAR in a single agent
100% detection, zero false positives across three consecutive MITRE ATT&CK Enterprise Evaluations
Transparent, publicly listed per-endpoint pricing
Windows, macOS and Linux support

Limitation to note: Cynet requires deploying its own agent, creating migration friction for organizations invested in CrowdStrike, SentinelOne or Defender. Not currently included in Gartner Magic Quadrant, which can complicate enterprise procurement. Strongest in SMB and mid-market deployments.

Choosing the best MDR provider for your operating model

The right MDR provider isn’t the one with the longest feature list or the most recognizable name. It’s the one that closes the specific gap your team has, at a cost and complexity level your organization can actually sustain.

Kaseya MDR is built for organizations that need 24/7 threat coverage without building a security team from scratch. The managed SOC handles detection, investigation and response around the clock, and AI-driven triage means your team only sees confirmed threats rather than a queue of raw alerts. For SMBs and internal IT teams that can’t justify a dedicated security function, that means serious protection without the overhead. For MSPs delivering security to clients, native PSA and RMM integration means incidents surface as actionable tickets in the workflows your team already uses.

For enterprises already on CrowdStrike or SentinelOne, Falcon Complete and Vigilance Respond are the natural extensions. For mid-market organizations without a dedicated SOC that want an ongoing security partner, Arctic Wolf’s concierge model delivers guidance alongside coverage. For mature security teams that value transparency and detection engineering, Expel and Red Canary serve that need well.

For organizations where cost and deployment speed matter most, Huntress delivers human-verified MDR at a price point that works for small-market budgets. Cynet 360 is worth evaluating for any team trying to consolidate its security stack while getting MDR coverage included rather than as a separate line item. Rapid7 and Sophos round out the mid-market tier for organizations that want coverage tiers that grow with their security program.

The question to ask before choosing isn’t which service has the most capabilities. It’s whether your organization will actually see fewer incidents and faster containment as a result of using it. That outcome is what MDR is ultimately paid to deliver.
