Polygraf AI today announced the appointment of Darren Lee to its Board of Directors. Lee brings decades of enterprise cybersecurity leadership experience, including senior executive roles at Proofpoint, where he helped scale global threat protection, identity defense, and compliance security platforms used by regulated organizations worldwide.
Lee’s appointment comes as Polygraf AI continues its rapid growth following major industry recognition, including being named “Most Innovative AI Usage Control for Security and Compliance” at the Global InfoSec Awards during RSA Conference 2026, and securing a core U.S. patent for its Content Source Detection AI technology.
During his 14-year tenure at Proofpoint, Lee served in multiple executive leadership roles, most recently as Executive Vice President and General Manager of the Threat Protection Business. In that role, he led global teams building and scaling technologies across email security, identity protection, human risk management, threat intelligence, and digital compliance. His leadership directly shaped enterprise security platforms deployed globally across financial services, healthcare, government agencies, and other highly regulated sectors.
Polygraf AI delivers preemptive, on-premise enforcement of data protection and compliance controls through its proprietary compute-lite AI Behavioral Control Plane, enabling organizations to detect and prevent sensitive data exposure across AI tools, enterprise workflows, and user environments. Its edge-AI architecture uses proprietary Small Language Models (SLMs) that run entirely on local hardware with as little as 1.3 GHz CPU and 40MB of RAM, eliminating the need to send data externally. This minimal energy footprint cuts operational & infrastructure costs by removing reliance on expensive cloud GPUs, while delivering a more sustainable alternative to carbon-intensive Large Language Models (LLMs).
The company’s recently launched Desktop Overlay extends these capabilities directly to desktop endpoints with zero integration requirements, providing real-time guidance that prevents data leakage before it occurs.
Lee’s addition to the Board strengthens Polygraf AI’s strategic leadership at a time when enterprises are accelerating AI adoption across mission-critical operations. His deep background in enterprise cybersecurity product development, governance technologies, and large-scale SaaS security platforms aligns closely with Polygraf AI’s focus on enabling safe and auditable AI deployment across regulated industries.
