ReliaQuest Reviews, Ratings & Features 2026 | Gartner Peer Insights

The security threat intelligence products and services market refers to the combination of products and services that deliver knowledge (context, mechanisms, indicators, implications and action-oriented advice), information and data about cybersecurity threats, threat actors and other cybersecurity-related issues. The output of these products and services aims to provide or assist in the curation of information about the identities, motivations, characteristics and methods of threats, commonly referred to as tactics, techniques and procedures (TTPs). The intent is to enable better decision making and improve security technology capabilities to reduce the likelihood and impact of a potential compromise. Threat intelligence (TI) products and services support the different stages of a TI process life cycle. In particular, this involves defining the aims and objectives, collecting and processing intelligence originating from various sources, analyzing and disseminating it to different stakeholders within the organization, and regularly providing feedback on the entire process. These products and services support ongoing security investigations and assist in preventing future breaches by prioritizing infrastructure hardening. TI tools and services are most commonly cloud-based products and services, but can also be delivered “as a service.”

This platform has a lot of potential but requires some dedicated resources to get the most out of the tools. Additionally, the value is low unless you buy multiple integrations. 

Operations Associate

The overall experince with RQ/GM has been great. It is easy to make changes, to talk to their engineers and to run playbooks.
