Telos Appoints Executive VP Mark Griffin as CEO Amid Federal Cyber Expansion
Telos Corp. has promoted 42-year company veteran Mark Griffin to chief executive officer, transitioning long-standing CEO John Wood to executive chairman. The leadership pivot follows a 50 percent revenue surge in 2025 driven by heavy Department of Defense and federal cyber defense commitments.
Telos Corporation has restructured its executive leadership, promoting 42-year company veteran Mark Griffin to Chief Executive Officer while long-serving CEO John Wood transitions to Executive Chairman of the Board. Wood, who assumed the chief executive role in 1994, will now concentrate on the cybersecurity vendor's overall product roadmap and long-term sales strategy. Griffin previously served as Executive Vice President, spending the last five years heading Telos' security solutions unit, where he oversaw the development and operational management of the firm's core intellectual property portfolio.
The C-suite transition comes on the heels of a notable financial turnaround for the defense and federal technology provider. Telos generated $164.8 million in revenue for fiscal year 2025, representing a 50 percent year-over-year expansion, while narrowing its full-year net loss from $52.5 million in 2024 down to $36.5 million. The firm’s revenue structure remains deeply anchored in federal mission support: government contracts accounted for 91 percent of overall 2025 revenue, with the Department of Defense alone generating 58 percent of total sales. The remaining 9 percent was generated across state and local government agencies and commercial markets.
For defense acquisition leadership and federal prime contractors, Griffin's elevation reflects a deliberate focus on operational execution and enterprise intellectual property commercialization across critical government networks. Telos maintains an influential footprint in high-assurance federal systems, notably serving as one of three primary contractors powering the Transportation Security Administration’s (TSA) PreCheck identity verification program. By bifurcating executive duties—placing Griffin over operational performance and financial strategy while assigning Wood to drive product direction—Telos positions itself to aggressively capture mid-tier DoD cybersecurity posture modernization and zero-trust identity architectures.
The move reinforces a broader trend across federal systems integrators: prioritizing internal domain expertise over outside leadership swaps during critical organic growth phases. Griffin’s three decades of executive operational experience provide direct continuity for ongoing defense cyber defense task orders. As federal agencies intensify requirements for secure multi-cloud access, credentials management, and critical infrastructure safeguards, Telos' recalibrated executive structure aims to sustain top-line momentum while accelerating its path to full operational profitability.
