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

Gartner Peer Insights logo on a light background

“Voice of the Customer” is a document that 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 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.

We believe the report categorizes vendors based on user interest, adoption, and overall experience to help security and risk management leaders understand how peers are using these technologies to strengthen their security posture.

About Adversarial Exposure Validation

Gartner defines Adversarial Exposure Validation (AEV) as technologies that deliver consistent, continuous, and automated evidence of the feasibility of an attack. These technologies confirm how potential attack techniques would successfully exploit an organization, and circumvent prevention and detection security controls. They achieve this by performing attack scenarios and modeling or measuring the outcome to prove the existence and exploitability of exposures.
