What Is Security Information and Event Management?

Security information and event management (SIEM) is a configurable system of record that collects, aggregates and analyzes security event data from on-premises and cloud environments. SIEM processes security event data for the purposes of threat detection, investigation and response. It natively supports data normalization and offers user-configurable detection content and reporting to orchestrate threat mitigation and satisfy compliance requirements. These solutions are delivered via a SaaS platform or client-hosted on-premises or private cloud.
The SIEM system must assist with:
  • Aggregating and normalizing data from various IT and operational technology (OT) environments
  • Designing and executing near real-time monitoring and alerting content
  • Enriching and investigating security events of interest
  • Supporting manual and automated response actions
  • Maintaining and reporting on current and historical event data

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 Magic Quadrant for Security Information and Event Management.
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. See Gartner Peer Insights Voice of the Customer Methodology for details.

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 security information and event management market, Gartner Peer Insights published 2,673 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 time frame 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.
