What Is Managed Detection and Response?

Gartner defines managed detection and response (MDR) services as those that provide customers with remotely delivered security operations center (SOC) functions. These functions allow organizations to perform rapid detection, analysis, investigation and response through threat disruption and containment. They offer a turnkey experience, using a predefined technology stack that commonly covers endpoints, networks, logs and cloud. Telemetry is analyzed within a provider’s platform using a range of techniques. The MDR provider’s analyst team then performs threat hunting and incident management to deliver recommended actions to their clients.
MDR offers outcome-driven security incident management that is predicated on the detection, analysis and investigation of potentially impactful security events and the delivery of active threat disruption and containment actions to respond to and mitigate the impact of cyber breaches.

What Is Gartner Peer Insights “Voice of the Customer”?

“Voice of the Customer” synthesizes Gartner Peer Insights reviews into insights for buyers of technology and services. This aggregated peer perspective, along with the individual detailed reviews, is complementary to Gartner’s expert research and can play a key role in your buying process. Peers are verified reviewers of a technology product or service, who not only rate the offering, but also provide valuable feedback to consider before making a purchase decision. You can read individual reviews and ratings on the Gartner Peer Insights page for this market.
Along with the historical peer-based perspective represented in this document, Gartner has a related expert-led Market Guide for Managed Detection and Response.
Figure 1 shows all “Voice of the Customer” eligible vendors in the market categorized into four quadrants based on scores assigned for User Interest and Adoption (x-axis), and Overall Experience (y-axis). The midpoint of each axis, labeled “market average,” represents the average score as calculated exclusively from vendors included in the document.

Methodology

A full description of the methodology can be found on the Gartner Peer Insights Voice of the Customer Methodology page.
Voice of the Customer includes vendors with products aligned to the market that have 20 or more eligible published reviews (and 15 or more ratings for “Capabilities” and “Support/Delivery”) during the 18-month consideration period ending 31 January 2026. Reviews from vendor partners or companies with less than $50 million in revenue are excluded.
In the managed detection and response market, Gartner Peer Insights published 1,914 reviews and ratings during the consideration period.
The data used in this report is drawn from reviews on Peer Insights, a free peer review and ratings platform that regularly publishes new reviews. The Voice of the Customer methodology uses a snapshot of reviews data from a defined timeframe and does not automatically update as new reviews are published. The external Peer Insights site will always have the most updated peer view of the vendors and products in this report.
The numerical ratings scores in each vendor summary graphic (shown as “Rating by Category”) are best interpreted as sample statistics with a reasonable margin for error and not as exact values.
