Managed Detection and Response Software Options 2026

Cyberattacks do not wait for office hours, and most organisations without a dedicated round the clock security operations centre are effectively blind between the point an attacker gets in and the point someone notices. Industry estimates still put average dwell time at around two weeks, and for many mid-sized organisations building an internal SOC to close that gap is neither affordable nor realistic.

This guide sets out the leading managed detection and response (MDR) providers on the market in 2026, across enterprise-scale platforms and mid-market and SME-focused services. Viewpoint Analysis is a Technology Matchmaker, helping IT and security buyers find and select the right technology fast - aiming to be the place buyers go to understand the software and technology market before speaking to vendors.

Several vendors covered here, including CrowdStrike, SentinelOne, and Sophos, also appear in our Endpoint Security Software Options 2026 post under different products - MDR is a managed service layered on top of detection technology, and the two are worth evaluating together rather than in isolation.

Included Vendors

This guide covers the following MDR providers, evaluated independently across enterprise and mid-market and SME tiers. Our viewpoint on each vendor follows below.

What is Managed Detection and Response (MDR) Software?

Managed detection and response is a service, not just a piece of software, that provides an organisation with remotely delivered security operations centre functions. A provider's analysts monitor telemetry from endpoints, networks, cloud environments, and identity systems around the clock, investigate anything suspicious, and take agreed action to contain a threat rather than simply raising an alert for an internal team to deal with.

MDR differs from managed EDR in scope. Managed EDR focuses mainly on endpoint detection, while MDR typically covers a wider set of surfaces and includes genuine investigation and response, not just monitoring. For a broader view of where MDR fits alongside firewalls, SIEM, and endpoint protection, see our IT Operations Technology page.

How to Find MDR Software

If you want a fast, personalised shortlist, our free Longlist Builder - powered by HUEY, the Viewpoint Analysis AI Technology Analysis Agent - generates a tailored longlist matched to your company size, location, and requirements in minutes.

If you would rather have vendors come to you, the Technology Matchmaker Service works like Dragons' Den or Shark Tank for technology buying. We interview your team, write a Challenge Brief, and invite qualified vendors to pitch directly to you.

Enterprise MDR Software Options 2026

CrowdStrike Falcon Complete Next-Gen MDR

CrowdStrike's Falcon Complete Next-Gen MDR runs on the same Falcon platform that underpins the company's endpoint security business, giving its analysts a single source of telemetry across endpoint, cloud, identity, and a growing list of third-party data sources. The service is fully managed, meaning CrowdStrike's own team investigates alerts and takes response action inside a customer's environment rather than simply flagging activity for an internal team to act on. Falcon Complete has built a reputation for fast detection and containment times, backed by a breach warranty that reimburses customers for costs if an attack occurs while the service is properly deployed. AI-native detection models sit alongside human analysts, with the platform correlating signals across surfaces before anything reaches a customer as an alert. CrowdStrike's scale means a large body of threat intelligence feeds directly into detection logic, drawn from the many millions of endpoints already running the Falcon agent worldwide. The service is priced and positioned for organisations that want a fully outsourced SOC function built on a single, unified platform.

Our Viewpoint: A strong fit for organisations already running or considering the Falcon platform who want fully managed detection and response with a genuine breach warranty behind it.

SentinelOne Singularity MDR

SentinelOne delivers MDR through its Vigilance service, built on top of the Singularity platform and its autonomous AI agents that can act even when a device is disconnected from the network. The platform's one-click rollback feature restores an endpoint to its state before an attack, which can turn a ransomware incident into a short operational interruption rather than a lengthy recovery project. Vigilance analysts provide 24/7 human oversight on top of the automated response, stepping in for more complex containment and forensic work that requires judgement. SentinelOne positions the service around flexibility, with no long-term lock-in and the ability to scale coverage up or down as an organisation's estate changes. Detection spans endpoint, cloud, and identity, with the underlying platform designed to anticipate attacker techniques rather than only reacting to known signatures. Pricing is transparent relative to some competitors, offered as a per-endpoint add-on to existing Singularity licences.

Our Viewpoint: A good option for organisations that already run or are evaluating SentinelOne's endpoint platform and want managed response layered directly on top of it.

ReliaQuest GreyMatter

ReliaQuest GreyMatter takes a different position to most of the vendors on this list, operating as a security operations platform that sits across an organisation's existing multi-vendor security stack rather than replacing it with a single proprietary agent. The platform pulls telemetry from whatever tools a customer already runs, including endpoint, SIEM, cloud, and identity products from other vendors, and layers detection content, automation, and response orchestration on top. This makes GreyMatter a strong option for large enterprises that already have an internal security team and existing security investments they do not want to strip out and replace. ReliaQuest's own analysts provide 24/7 monitoring and investigation, with automated response actions that can be executed directly inside a customer's existing tools rather than a separate console. The model is closer to augmenting an in-house SOC than fully outsourcing it, which suits organisations that want to keep security decision-making internal while adding scale and coverage. GreyMatter has built strong recognition among large enterprises running complex, multi-vendor security environments.

Our Viewpoint: Particularly well suited to large enterprises with an existing SOC and a multi-vendor security stack who want to add coverage and automation rather than replace what they already have.

Red Canary

Red Canary built its reputation as a specialist MDR provider rather than a security platform vendor that added managed services later, and that focus still shows in how the service operates. The platform is intentionally telemetry-source agnostic, integrating with a customer's existing endpoint, cloud, identity, and SaaS tools rather than requiring a single proprietary agent across the estate. Detection engineering is a particular strength, with Red Canary publishing detailed threat research and maintaining a large library of detection logic that its analysts continuously refine. The service includes 24/7 monitoring, investigation, and response, with clear documentation of what the team will and will not do without customer sign-off, which larger organisations often value during procurement. Red Canary is frequently selected by enterprises that already run a strong internal security programme and want a specialist partner for continuous monitoring and threat hunting specifically, rather than a broader platform play. Reporting is detailed and built for security teams that want to understand exactly why a detection fired.

Our Viewpoint: A strong choice for enterprises with a mature internal security function who want a specialist MDR partner focused purely on detection quality and threat hunting.

Sophos MDR

Sophos completed its acquisition of Secureworks in February 2025, bringing the well regarded Taegis XDR and MDR platform, its Counter Threat Unit research team, and Secureworks' identity threat detection capabilities under the Sophos brand. The combined business is now the largest pure-play MDR provider by customer count, supporting organisations from SMBs through to large enterprises across two distinct service lines. Sophos MDR remains the more turnkey, broadly accessible service, while Taegis continues to operate as an open platform that works across a customer's existing security tools rather than requiring Sophos products throughout. Sophos Endpoint is now natively included with Taegis subscriptions at no extra licence cost, reducing the total cost of running the combined stack for customers who adopt both. Integration work between the two businesses is ongoing through 2026, and buyers evaluating either Sophos MDR or Secureworks Taegis should check current roadmap and integration status as part of due diligence given the pace of change. Combined threat intelligence from both organisations now feeds a single research function, Sophos X-Ops, strengthening detection content across the portfolio.

Our Viewpoint: Worth close consideration for organisations already using Sophos Endpoint, and for larger enterprises attracted to Taegis as an open, multi-vendor MDR and XDR platform.

MDR Software for Mid-Market and SME Buyers

Arctic Wolf

Arctic Wolf is the largest MDR provider by revenue in the commercial mid-market, built around its Concierge Security Team model that pairs each customer with named security engineers rather than a rotating pool of analysts. The service covers endpoint, network, cloud, and identity telemetry, delivered through Arctic Wolf's own platform alongside 24/7 monitoring and guided response. A large managed service provider channel gives Arctic Wolf broad reach into organisations that buy security through an existing IT partner rather than directly. The Concierge model extends beyond pure detection and response into ongoing risk guidance, with the assigned security team providing regular reviews and recommendations rather than only responding when something goes wrong. Arctic Wolf has consistently been positioned as a Leader in independent analyst evaluations of the MDR market, reflecting its scale and maturity. The service is built for organisations that want a genuinely managed relationship rather than a purely technical integration.

Our Viewpoint: A strong fit for mid-market organisations that want an ongoing, named relationship with their security team rather than a purely automated or ticket-based service.

Rapid7 MDR

Rapid7 built its MDR service on top of its existing InsightIDR platform, giving customers a natural upgrade path if they already use Rapid7 for vulnerability management or SIEM. The service adds 24/7 monitoring, investigation, and response from Rapid7's own analyst team, with detection content informed by the company's broader research into attacker behaviour and exposure management. Rapid7 positions MDR as one part of a wider exposure management story, connecting detection and response back to vulnerability data so customers can see not just what was detected but what made the attack path possible in the first place. The service supports a wide range of telemetry sources beyond Rapid7's own products, including common EDR, cloud, and identity tools already in use. Response actions are agreed with the customer in advance through a documented playbook, giving security teams clarity on what Rapid7 will act on directly versus escalate. Rapid7 is a familiar, established name for security teams already invested in its broader product family.

Our Viewpoint: A logical choice for organisations already using Rapid7 for vulnerability management or SIEM who want detection and response from the same vendor and data set.

eSentire

eSentire positions itself around speed of response, publishing mean time to contain figures as a core part of its pitch to buyers comparing MDR providers. The service is built to be telemetry agnostic, working across a customer's existing endpoint, network, cloud, and identity tools rather than requiring a specific technology stack. eSentire's analysts operate from Security Operations Centres that provide continuous coverage, with documented response actions that can isolate a host or disable an account without waiting for customer approval when a threat meets pre-agreed criteria. The company has built a specific reputation in regulated mid-market sectors including financial services, legal, and professional services, where compliance requirements shape how security operations need to be documented and run. eSentire also offers digital forensics and incident response as an extension of its MDR service, useful for customers who want one provider across both routine monitoring and a serious incident. Threat intelligence is shared across the customer base, with findings from one investigation informing detection logic applied to others.

Our Viewpoint: Worth shortlisting for mid-market organisations in regulated sectors that want fast, pre-authorised containment actions and a provider comfortable working across a mixed security stack.

Expel

Expel built its MDR service around transparency, giving customers direct visibility into the detection logic, alert reasoning, and response actions its analysts take rather than treating the investigation process as a black box. The platform, Expel Workbench, is provided to customers alongside the managed service, so internal security staff can see exactly what Expel's analysts are looking at in real time rather than only receiving a summary after the fact. Expel is deliberately built to work across a wide range of existing security tools, including common EDR, cloud, SaaS, and identity platforms, rather than pushing customers toward a proprietary agent. Response actions are automated where an organisation has pre-approved them, with Expel able to act directly inside a customer's existing tools rather than requiring a separate console. The company has a strong reputation for clear, readable reporting that a smaller security team, or a team with no dedicated security headcount at all, can act on without extensive translation. Expel is commonly selected by organisations that want an outsourced SOC function but still want to understand and retain oversight of how decisions are made.

Our Viewpoint: A strong option for organisations that want full transparency into how their MDR provider reaches decisions, rather than a service that operates as a closed system.

Huntress

Huntress was built specifically for organisations without an internal security team, and that focus runs through the product rather than being an afterthought layered onto an enterprise platform. The service combines managed EDR, identity threat detection, and 24/7 human-led threat hunting from its own SOC, aimed at closing gaps that automated tools alone tend to miss. Huntress is a common choice for managed service providers supporting small and medium-sized business clients, since the platform is built for multi-tenant management across many customer environments from a single console. Pricing is transparent and scales predictably by endpoint, which suits smaller organisations that need to budget precisely rather than negotiate a custom enterprise contract. The company has expanded beyond pure endpoint coverage into Microsoft 365 identity protection and security awareness training, giving smaller buyers a wider net of coverage from one vendor relationship. Huntress analysts investigate and validate detections before they reach a customer, reducing the alert noise that a lean IT team would otherwise have to triage itself.

Our Viewpoint: A strong starting point for smaller organisations and IT teams without dedicated security headcount who need genuinely managed detection without enterprise-level complexity or cost.

How to Select MDR Software

Telemetry coverage and technology fit: Check whether the provider requires its own proprietary agent across your estate or works across the endpoint, cloud, and identity tools you already run. A telemetry-agnostic provider can be a better fit if you have existing security investments you do not want to replace.

Response authority and playbook: Ask exactly what actions the provider can take without waiting for your approval, such as isolating a host or disabling a compromised account, and get this documented. The gap between a provider that monitors and alerts versus one that actually contains a threat can be the difference that matters most in a real incident.

SOC model and communication: Some providers assign a named team who get to know your environment over time, while others operate a more ticket-based model. Consider whether you want direct visibility into the provider's own tooling and investigation process, or whether a summarised report after the fact is sufficient for your team.

Compliance, reporting, and guarantees: For regulated sectors, check what audit-ready reporting the service produces as standard, rather than on request. A small number of providers back their service with a breach warranty or defined response time SLAs, which is worth factoring into a like-for-like comparison.

Structured processes such as Rapid RFI, Rapid RFP, and 30-Day Selection - all delivered through our Technology Selection Services - can shorten this evaluation considerably. For a deeper reference on selection methodology, see our Enterprise Software Selection Playbook 2026.

Summary

The MDR market has consolidated around a small number of models. CrowdStrike, SentinelOne, and Sophos deliver MDR as a managed layer on top of their own endpoint platforms, ReliaQuest and Red Canary operate as specialist, multi-vendor SOC augmentation services, and Arctic Wolf, Rapid7, eSentire, Expel, and Huntress each serve the mid-market and SME end of the buyer spectrum with different strengths in relationship model, transparency, or affordability.

The Sophos and Secureworks merger is worth watching closely if either Sophos MDR or Secureworks Taegis is on your shortlist, since integration between the two businesses is still underway through 2026. Beyond that specific development, the most useful filter for narrowing this list is whether you want a fully outsourced SOC function or a service that augments a security team you already have in place.
