Quadrant Information Security

Quadrant Information Security runs managed detection and response (MDR/MXDR) built around Sagan, its own multi-threaded SIEM and intrusion detection engine. Rather than reselling a third-party SIEM, Quadrant develops and maintains Sagan’s detection logic in house, with more than 7,500 internally developed attack signatures used to detect and validate malicious activity, and pairs that platform with managed risk, threat exposure, and virtual CISO advisory services aimed at middle-market organizations that can’t staff a full SOC themselves.

Founded in 2011 and headquartered in Jacksonville, Florida, Quadrant was acquired by investment firm Worklyn Partners in January 2022, shortly after Worklyn closed the first tranche of its debut fund at over $35 million. The deal was structured as growth capital to help Quadrant scale its Sagan platform and accelerate expansion rather than a strategic acquisition by a competing security vendor, and Quadrant continues to operate under its own brand and leadership with roughly 26 employees.

Building and maintaining a proprietary detection engine, rather than operating on top of a licensed SIEM, is a real differentiator for a company Quadrant’s size, and its private-equity backing gives it capital for growth without folding it into a larger security vendor’s product roadmap. Its footprint remains concentrated in the middle market rather than large enterprise, where MDR competition from bigger, more heavily-funded players is intense.
