ReliaQuest MDR is an outsourced security-operations service covering continuous monitoring, threat detection, investigation, and incident response. Its overview describes real-time 24/7 coverage, with providers able to hunt proactively for unknown threats. The service works with GreyMatter, an agentic AI security-operations platform for detection, containment, investigation, and response across cloud, hybrid, and on-premises technologies. GreyMatter connects with more than 300 technology partners, including SIEM, EDR, network-security, and cloud tools, and can unify connected sources without moving their data. ReliaQuest offers proof-of-value engagements with trial periods and success criteria agreed before work begins. GreyMatter pricing is per endpoint for the core platform, with additional capabilities priced by covered scope rather than token usage. ReliaQuest says log data is retained for 72 hours for investigations and 30 to 90 days for hunt campaigns, configured by the customer. Pricing is available on request.
