Security management platform vendor ReliaQuest today announced that it has purchased Austin, Texas-based attack simulation firm Threatcare. ReliaQuest plans to add Threatcare's technology to its GreyMatter security platform for security operation centers (SOCs) and security teams.

Threatcare founder and CEO Marcus Carey will join the chief technology officer at ReliaQuest, and all of Threatcare's team members will become part of Tampa, Florida-based ReliaQuest. Financial details of the deal were not disclosed.

GreyMatter integrates security data from security incident and event manager (SIEM), endpoint detection and response (EDR), firewalls, threat intelligence feeds, and other security tools, and includes analysis functions and automation. Threatcare's technology — which will become a new feature on the platform — simulates how a specific threat or attack could target an organization's network in order to determine whether its security tools and settings are or are not actually working to thwart the threats.

Brian Murphy, CEO and founder of ReliaQuest, says that adding Threatcare's function to the platform will enhance the "quality and efficacy" of organizations' automated detection and response operations. "There's something really valuable about taking rules, alerts, and dashboards and correlating them" and then adding the ability to regularly test security controls, he says.

Threatcare's Carey says the goal is to create an attack simulation when a new threat emerges: "Then push that content to GreyMatter to the security team, and automatically test it on the fly," he says.

ReliaQuest, which is privately held, to date has some 200 large enterprise customers from the Fortune 1000, according to Murphy.
