Quadrant Information Security
Jacksonville-based MDR provider whose proprietary Sagan SIEM and IDS engine, backed by over 7,500 internally developed detection signatures, anchors its managed threat detection service.

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.
Innovation Matrix Assessment
Sagan's detection-signature library has grown to over 7,500 internally developed signatures, indicating ongoing content development, though no major platform re-architecture or new product line was found since the Worklyn investment.
Over a decade of operating history, a proprietary detection platform maintained in house rather than licensed, and continued independent operation post-acquisition under Worklyn Partners point to solid operational maturity for a middle-market MDR provider.
The 2022 Worklyn Partners growth investment, tied to the first close of Worklyn's $35M+ debut fund, is a real capital-driven momentum signal, though no more recent (2024-2026) growth or funding news was found.
MDR services layered on a proprietary SIEM/IDS engine is a proven, established model; Quadrant's differentiation is depth of in-house signature development rather than a structurally new approach to detection.
The scale of Sagan's signature library (7,500+) is independently documented, but no third-party MDR benchmark, MITRE ATT&CK evaluation, or named breach-prevention case study was found to validate real-world detection efficacy.
Middle-market organizations that can't build an internal SOC remain a large, underserved segment for managed detection and response, and that is precisely who Quadrant is built to serve.
Why CISOs Should Care
Gives middle-market organizations that can't staff a 24/7 SOC access to a purpose-built, actively maintained detection engine (Sagan) and MDR service, backed by growth capital rather than folded into a larger vendor's roadmap after acquisition.
What Makes It Different
Maintains its own proprietary SIEM/IDS detection engine (Sagan) rather than reselling or white-labeling a third-party platform, giving it more control over detection logic than most MDR providers of similar size.
The Matrix Verdict
52/100 — INCREMENTAL INNOVATOR
A solid, decade-plus middle-market MDR provider with a genuinely proprietary detection engine and private-equity backing for growth; it competes in a crowded MDR field without the scale or brand visibility of larger managed detection vendors.
Editorial Note: Claims vs. Verified Findings
The Worklyn Partners acquisition, fund size, and Quadrant's Sagan signature count are independently confirmed via MSSP Alert, Help Net Security, and PRWeb coverage of the deal. Specific efficacy or detection-rate claims for Sagan were not found and are not independently verified.
