MDR vs. EDR: What’s the difference and which is right for you?

EDR and MDR both appear in conversations about endpoint security — and the two are easy to conflate. They share overlapping goals, and MDR services frequently use EDR technology as part of their delivery. However, they’re not the same thing, and the distinction matters when you’re deciding how to protect a business or build a security service stack.

The short version: EDR is a technology. MDR is a service. One gives you the tools to detect and respond to threats. The other provides the people and processes to run those tools on your behalf. For organizations evaluating both options, and for MSPs trying to position them correctly, understanding exactly where each one starts and stops is the right place to begin.

Kaseya offers both Datto EDR as an endpoint security tool and Kaseya MDR as a fully managed SOC service, which gives us a direct view of how these two categories work together in practice across MSP and SMB environments.

What is the difference between MDR and EDR?

The clearest way to frame the difference: EDR is a software tool, and MDR is a managed service. That distinction drives almost everything else that separates them.

Endpoint detection and response (EDR)

EDR is a security platform that monitors endpoint devices continuously for signs of malicious activity. A lightweight agent installed on each device, including desktops, laptops, servers and virtual machines, collects telemetry on process execution, file modifications, registry changes and network connections in real time. When behavior deviates from a baseline, the platform detects it, alerts the security team and can take automated response actions such as isolating the affected device or terminating a malicious process.

EDR gives security teams deep visibility into what’s happening on every endpoint. Although the technology itself is highly capable, it requires someone to deploy it correctly, tune it to reduce false positives, review alerts, investigate threats and respond to incidents. That operational layer is not part of the product.

For a full breakdown of how EDR works, see our guide to endpoint detection and response.

Managed detection and response (MDR)

MDR is a service in which a third-party provider takes on the monitoring, detection, investigation and response functions that EDR technology requires. MDR providers operate a security operations center (SOC) staffed by experienced analysts who work on behalf of client organizations 24 hours a day, seven days a week.

A typical MDR service includes continuous monitoring, alert triage, threat investigation, proactive threat hunting and incident response. Most MDR providers monitor beyond just the endpoint: they ingest telemetry from network traffic, cloud workloads, identity systems and email alongside endpoint data, correlating signals across the environment to detect threats that no single tool would surface alone.

According to MarketsandMarkets, the global MDR market was valued at $6.28 billion in 2026 and is projected to reach $19.01 billion by 2031, growing at a compound annual growth rate of 24.8%. That growth reflects a fundamental shift: organizations of all sizes are recognizing that technology alone isn’t enough and that the analyst layer is where security outcomes are actually determined.

MDR vs. EDR: Key differences

EDR and MDR are not direct competitors. One is a tool category, the other is a service model. But organizations frequently face a choice between investing in EDR software and managing it themselves versus purchasing an MDR service that handles that function for them.

Technology versus service

The most important distinction in the table above is the first row. EDR is software. MDR is a service that typically includes software as a component, but the defining value is the human expertise layered on top of it.

An EDR platform deployed without competent analysts reviewing alerts, tuning detections and responding to incidents is significantly less effective than its specifications suggest. The technology is only as good as the team operating it. MDR solves this by making the analyst layer part of the service contract.

Coverage scope

Most EDR platforms are endpoint-focused by design. Some modern EDR tools have expanded their scope, but the core product monitors device-level activity. MDR services typically monitor a broader attack surface: endpoints, Microsoft 365 and cloud app activity, network traffic and identity systems are commonly included. This broader coverage is particularly relevant for multi-stage attacks that move between surfaces after initial endpoint compromise.

Internal resource requirements

Standalone EDR requires a team that can configure the platform, tune detections to the specific environment, review the alert queue, investigate confirmed threats and coordinate response. For many SMBs and lean IT teams, that capacity doesn’t exist. MDR removes that dependency. The provider’s analysts handle monitoring and response, and the internal team’s role is largely limited to initial setup, scoping and acting on recommendations.

Benefits of EDR

EDR’s strengths are most apparent for organizations that have the in-house capability to operate the technology and want direct control over their security tooling.

Full control and visibility
With EDR, the security team owns the tool and the data it produces. Alert configurations, response thresholds and forensic investigations are all managed internally. For organizations with mature security teams, that level of control is an advantage: detections can be tuned precisely to the environment, and institutional knowledge about the client estate stays in-house.

Deep endpoint forensics
EDR produces granular device-level telemetry that MDR services don’t always replicate in their reporting. The full process tree, file modification history and network connection log for a specific device are available in the EDR console. For post-incident investigation and cyber insurance documentation, that level of detail is often required.

Lower cost at scale for well-staffed teams
For MSPs with experienced security staff already managing endpoint environments, EDR’s per-endpoint licensing model can be more cost-effective than a full MDR subscription. The economics shift significantly based on team capacity: the more capable the internal team, the more value a standalone EDR deployment returns per dollar spent.

Purpose-built for MSP delivery
EDR platforms designed for MSPs, such as Datto EDR, integrate natively with RMM tools and allow a single team to manage endpoint security across dozens of client environments from one console. This multi-tenancy model is a structural advantage that most MDR services aren’t designed to replicate.

Benefits of MDR

MDR’s advantages become most apparent when the internal team’s capacity is the constraint, which is the case for most SMBs and many mid-market organizations.

24/7 expert coverage without headcount
MDR’s most direct value proposition is access to experienced security analysts around the clock without the cost and difficulty of building that capability internally. According to the ISC2 2024 Cybersecurity Workforce Study, the global cybersecurity workforce gap reached 4.8 million unfilled positions in 2024. For most organizations, hiring the analysts needed to run an effective EDR deployment is simply not achievable. MDR provides that expertise as a service.

Faster detection and response times
MDR providers operate dedicated SOC teams whose sole function is monitoring and responding to threats. Average response times from alert to containment are significantly faster through an MDR service than through an in-house team balancing security alongside other IT responsibilities. Speed of containment directly determines the scale of damage in most ransomware and lateral movement scenarios.

Proactive threat hunting
Most MDR services include regular threat hunting: analysts actively searching for attacker behavior that hasn’t yet triggered an automated alert. This proactive function is rarely possible for internal teams without dedicated security headcount. It’s particularly effective against advanced persistent threats that operate slowly and quietly to avoid detection.

Broader attack surface coverage
MDR services monitor beyond the endpoint. By ingesting telemetry from network, cloud and identity sources alongside endpoint data, MDR providers can detect threats that move between surfaces. An attacker who compromises an endpoint and then pivots to a cloud application using stolen credentials may be invisible in EDR alone. MDR’s broader telemetry scope can catch the full attack chain.

Compliance support
MDR providers typically deliver regular reporting: monthly threat summaries, incident documentation and compliance evidence that internal teams can present to auditors or cyber insurers. This documentation function is operationally valuable for organizations in regulated industries where continuous monitoring must be evidenced.

Why MDR and EDR are more effective together

MDR and EDR are more often complementary than they are alternatives. Most MDR services use EDR technology as the endpoint telemetry layer within their broader monitoring stack. The EDR platform collects granular device-level data, and the MDR provider’s analysts use that data alongside network, cloud and identity telemetry to investigate threats in full context.

For MSPs, this model creates a natural tiered service structure. Datto EDR can be deployed as a standalone managed EDR offering, with the MSP’s own team handling monitoring and response for clients with lower security requirements. For clients that need 24/7 SOC coverage, or for incidents that exceed the MSP’s internal capacity, Kaseya MDR provides the analyst layer: monitoring endpoints, Microsoft 365 and firewalls around the clock, triaging alerts and coordinating response.

The two products share the same platform ecosystem, which means the switch between models doesn’t require re-deploying agents or reconfiguring telemetry pipelines. An MSP can start with Datto EDR for a client, add Kaseya MDR coverage when the client’s needs or regulatory requirements change and scale back if circumstances shift. That flexibility is structurally different from purchasing standalone tools from separate vendors.

MDR vs. EDR: How to choose the right solution

The right answer depends on your team’s security capacity, the complexity of the environments you’re protecting and what level of coverage your clients or organization actually requires.

EDR is the right choice if:

• You have experienced security staff in-house who can manage alerts, tune detections and respond to incidents
• You’re an MSP building a managed endpoint security service and want direct control over the tooling and pricing
• Your clients have straightforward environments where endpoint coverage is the primary security concern
• You need a cost-effective per-endpoint solution that integrates tightly with your RMM workflow

MDR is the right choice if:

• Your team doesn’t have the capacity or expertise to operate EDR effectively without outside support
• Your clients need 24/7 coverage and you can’t staff an overnight queue
• You’re serving clients with regulatory compliance requirements that mandate continuous monitoring and documented response
• You’re dealing with environments complex enough that endpoint-only visibility isn’t sufficient

For MSPs, the most common path is both. Deploy EDR across client estates as the foundational security layer. For clients with higher requirements, or when an incident exceeds your team’s capacity, use an MDR service to extend coverage. The important thing is knowing which clients need which level of service, and having the tooling to deliver both without running two entirely separate workflows.

Stay secure with Kaseya

EDR and MDR address the same underlying problem from different angles. EDR gives you the technology to detect and respond to endpoint threats. MDR gives you the people and processes to run that technology around the clock, across a broader attack surface, without requiring you to build a SOC from scratch.

For businesses and IT teams evaluating their options, the question isn’t which tool is better. It’s whether you have the internal capacity to operate EDR effectively, or whether a managed service that handles monitoring, triage and response on your behalf is the more practical path to the same level of protection.

For MSPs, Datto EDR provides the endpoint security platform to deliver managed EDR as a scalable per-client service. Kaseya MDR extends that with 24/7 SOC-backed monitoring across endpoints, Microsoft 365 and firewalls, with Kaseya’s analysts triaging alerts and coordinating response on the MSP’s behalf. Both are designed to work together and to scale as requirements grow.

Security maturity is a journey, not a binary choice. Start with the right tools, add the right services when the need is there, and build toward a stack that actually matches what you’re protecting.
