For small and mid-sized businesses comparing managed detection and response providers, ESET and Sophos almost always make the shortlist. Both run round-the-clock security operations, both pair human analysts with automation and both promise to detect and stop the threats that slip past preventive tools.

But the two services are built on different philosophies. ESET leads with research-grade threat intelligence and a single unified platform, while Sophos leads with ecosystem breadth, flexible response control and a financial breach warranty.

This guide breaks down how they compare on tiers, speed, coverage, intelligence, pricing and real-world fit, so you can match the right service to your environment.

Key takeaways

• ESET MDR is built on the ESET PROTECT platform and reports a six-minute detection-to-response time, with its research pedigree as the standout strength.

• Sophos MDR protects more than 39,000 organizations, offers three threat response modes and includes a breach protection warranty of up to $1 million on its Complete tier.

• ESET offers two tiers, PROTECT MDR for SMBs and MDR Ultimate for enterprises, while Sophos splits MDR Essentials from the fuller MDR Complete.

• Sophos provides more than 350 third-party integrations and works across mixed vendor stacks, whereas ESET MDR is strongest inside its own platform.

• Both hold strong analyst recognition, with ESET a KuppingerCole MDR Leader and Sophos a 2026 Gartner Peer Insights Customers’ Choice.

ESET MDR overview

ESET delivers managed detection and response on top of the ESET PROTECT platform, the same cloud console that powers its endpoint protection. MDR sits as the top tier in a five-tier lineup that runs Entry, Advanced, Complete, Elite and MDR, so customers can scale into managed services from an existing ESET deployment. The service blends AI-driven detection with human-led threat hunting, drawing on indicators of compromise, indicators of attack and user behavior analytics, with extended detection and response powered by ESET Inspect.

ESET offers two managed tiers. ESET PROTECT MDR targets small and mid-sized businesses and is available from a low device count, without the high endpoint minimums that some enterprise MDR vendors impose, while MDR Ultimate is aimed at enterprises and layers on dedicated threat hunting and digital forensic incident response. ESET reports a detection-to-response time of six minutes, which it positions as one of the fastest in the category.

Its credibility rests on deep research. ESET is part of the CISA-led Joint Cyber Defense Collaborative, fields more than 100 threat hunters and runs a telemetry network of over 100 million sensors across 11 R&D centers, backed by more than 35 years of malware research. It was named a Market and Product Leader in the 2024 KuppingerCole Leadership Compass for MDR and protects more than 500,000 businesses worldwide. For businesses that want fast research-led detection under one roof, ESET MDR scales from SMB to enterprise without switching vendors.

Sophos MDR overview

Sophos MDR is a fully managed service that protects more than 39,000 organizations worldwide, which Sophos says is more than any other MDR provider. It runs on the Sophos Central cloud console and draws intelligence from the Sophos X-Ops threat research unit, with telemetry compounded across the company’s 600,000-plus total customers. Sophos operates nine regional security operations teams for follow-the-sun global coverage.

The service comes in two tiers. MDR Essentials provides 24/7 monitoring, investigation and threat containment, but leaves cleanup and remediation to the customer, while MDR Complete adds full-scale incident response, root cause analysis, a dedicated incident response lead and the breach protection warranty. A defining feature is the choice of response style, delivered through three threat response modes that control how much the Sophos team does on your behalf.

Sophos backs its service with hard proof points. It posted 100 percent detection in the 2025 MITRE ATT&CK evaluation, offers more than 350 third-party integrations across endpoint, network, cloud, identity, email and business applications, and following its 2025 acquisition of Secureworks, it also offers the enterprise-grade Taegis MDR.

Service tiers and what is included

ESET keeps its tiering simple. PROTECT MDR covers the core managed service: continuous threat monitoring, triage and response, expert-led and active campaign threat hunting, a global threat intelligence team, a behavior patterns library and standard weekly or monthly reporting. MDR Ultimate builds on that with retrospective and customized threat hunting, attack vector visibility, digital forensic incident response, a dedicated incident response lead and advanced custom reporting, which makes it the enterprise option.

Sophos splits its service on the depth of response rather than the depth of hunting. MDR Essentials handles monitoring, investigation and threat containment, but the customer owns cleanup and remediation. MDR Complete is the fuller package, adding full-scale incident response at no extra cost, root cause analysis, a dedicated incident response lead and the $1 million breach protection warranty, which makes Complete the tier most SMBs without security staff will want.

Detection and response speed

Speed is ESET’s headline claim. It reports a six-minute detection-to-response time, positioning the service among the fastest in the market. Sophos takes a more contractual approach, publishing a 60-minute response-time SLA for 90 percent of high-severity cases on MDR Complete, alongside a reported 38-minute average case closure time.

These figures measure different points in the incident lifecycle, so they are not directly comparable. ESET’s number reflects how quickly it moves from detection to response, while Sophos’s SLA is a guaranteed contractual commitment with service credits attached. If raw speed is your priority, ESET’s claim is the stronger marketing point. If a contractually guaranteed SLA matters more, Sophos puts that promise in writing.

Threat response, control and incident handling

Sophos gives buyers unusually granular control over how incidents are handled through three threat response modes. In Notify Only, the team simply alerts you; in Collaborate, they investigate and act only with your consent, and in Authorize, they contain and remediate threats on your behalf and inform you afterward. Collaboration is the default, and MDR Complete customers in Authorize mode get full neutralization handled for them.

ESET takes a more uniformly analyst-led approach across both tiers, with its team performing containment and eradication as part of the service. Where ESET pulls ahead is deep incident work on MDR Ultimate, which includes digital forensic incident response and a dedicated incident response lead who can drive an end-to-end resolution. Sophos matches the dedicated IR lead on MDR Complete, so at the top tiers, both cover serious incident handling, just packaged differently.

Coverage, integrations and deployment

This is the clearest split between the two. Sophos is built for mixed environments, with more than 350 integrations spanning endpoint, network, cloud, identity, email and business applications, plus an XDR Sensor that ingests third-party telemetry and the deepest Microsoft 365 and Defender coverage of any MDR provider. It works for organizations already running CrowdStrike, SentinelOne, Microsoft, or other tools.

ESET MDR is platform-native. It is fastest to deploy and cleanest to run for organizations standardizing on ESET PROTECT, since the agent, console and managed service all come from one vendor. The trade-off is less flexibility for heavily mixed stacks, though ESET counters with broad operating system support across Windows, macOS, Linux, Android and iOS, plus a SOC 2 Type 2 certified service that appeals to compliance-focused buyers.

Threat intelligence and research

Both vendors invest heavily here, but in different ways. ESET’s strength is research depth: more than 35 years of malware research, 11 R&D centers, a 100-million-sensor telemetry network, and membership in the CISA-led Joint Cyber Defense Collaborative give its analysts early sight of emerging campaigns and advanced persistent threats.

Sophos counters with operational scale. Its X-Ops unit unifies threat intelligence, and that intelligence compounds across more than 600,000 protected organizations and nine regional security operations teams. The Secureworks acquisition added further threat research and the Taegis platform. In short, ESET’s edge is pedigree and original research, while Sophos’s edge is breadth of telemetry and around-the-clock operational coverage.

Pricing, breach of warranty, and contracts

Both services are quote-based, so your cost depends on endpoints, tier, and contract length. ESET MDR is sold through the ESET PROTECT platform, where entry tiers start in the low hundreds of dollars per year for a handful of devices, and the top MDR tier is priced on request. It can be bought online for up to 100 devices and through sales for larger deployments. Third-party estimates put Sophos MDR in the range of roughly $5 to $20 per asset per month, depending on tier.

The decisive difference is the warranty. Sophos MDR Complete includes a breach protection warranty covering up to $1 million in response expenses, at up to $1,000 per breached endpoint, with no separate cost. It is limited to a single claim and excludes the first 60 days of a subscription, but it remains a genuine financial backstop that ESET does not publicly match. For buyers who weigh cyber insurance alignment heavily, that warranty can tip the decision.

Analyst recognition and customer proof

Both services are well regarded by analysts and customers, which lowers the risk of either choice. ESET was named a Market and Product Leader in the 2024 KuppingerCole Leadership Compass for MDR, a Leader in the 2024 IDC MarketScape for Modern Endpoint Security, and a Top Player in Radicati’s APT protection quadrant for five consecutive years.

Sophos has been recognized as a Gartner Peer Insights Customers’ Choice for MDR, scoring 4.8 out of 5 from 290 customer reviews in the March 2026 Voice of the Customer report as the most-reviewed vendor in the category, and a Leader in the IDC MarketScape for Worldwide MDR Services. It also posted a perfect 100 percent detection result in the 2025 MITRE ATT&CK evaluation.

Where each service fits best

Choose ESET MDR if you value fast research-led detection, want a single platform that scales cleanly from a small business to an enterprise, already run or plan to run ESET endpoint protection, or need multi-language and GDPR-aligned operations. Its low entry threshold also makes it accessible to smaller teams that larger enterprise vendors tend to price out.

Choose Sophos MDR if you run a mixed vendor environment that benefits from 350-plus integrations, want granular control over how incidents are handled, or treat a built-in breach warranty as a must-have. Its Microsoft 365 depth makes it especially strong for Microsoft-centric organizations.

The verdict

ESET MDR and Sophos MDR are both credible, analyst-recognized services, so neither is a wrong choice for a mid-sized business. ESET wins on detection speed, research pedigree, and platform simplicity, making it the better fit for teams that want fast intelligence-led protection under one roof with the option to scale to enterprise-grade forensics.

Sophos wins on integration breadth, response flexibility, and financial protection, making it the better fit for mixed environments and buyers who want a contractual SLA and a breach warranty. The smartest move is to scope a trial of each against your actual stack, then judge them on detection quality and how clearly they communicate during a live incident.
