Zyston

Zyston, LLC operates as a managed security service provider (MSSP) delivering end-to-end cybersecurity solutions. The firm was established in May 2016 in Dallas, Texas, by a group of security and IT veterans, including Craig Stamm, who currently serves as President and CEO. Stamm, with a background that includes serving as president of brand protection firm Authentix and CFO of CareerBuilder, identified a significant market opportunity in the rapidly growing cybersecurity sector. He assembled a founding team with experience from prominent roles at companies like Fujitsu and PwC to address the complex security challenges faced by mid-market companies.

The company's business model is centered on providing a comprehensive portfolio of services that help clients build, operate, and mature their information security programs. Zyston targets companies with annual revenues typically ranging from $100 million to $2 billion, offering them services that might otherwise be out of reach. Revenue is generated through a combination of managed services, consulting and advisory services, and talent acquisition support. This multi-faceted approach addresses the three core pillars of cybersecurity: people, processes, and technology. A key differentiator is the assignment of a dedicated Cybersecurity Program Manager (CPM) to each client, who acts as a liaison between the client's IT team and Zyston's Security Operations Center (SOC), ensuring clear communication and effective remediation.

At the core of its service offering is CyberCAST, a proprietary, AI-driven software platform for cybersecurity program management. This solution provides clients with a quantifiable security score, risk assessments, and a strategic roadmap for improving their security posture over time. The platform translates complex security metrics into business-level reporting, making the information accessible to executive decision-makers. Services include 24/7 managed detection and response (MDR) from its Dallas-based SOC, vulnerability management, and managed SIEM. A significant milestone was the July 2023 strategic growth investment from Sverica Capital Management, aimed at accelerating growth. This was followed by the strategic acquisition of Blue Lava in October 2023, a move intended to enhance Zyston's CyberCAST platform and its security performance management capabilities.
