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.

Polygraf AI today announced the launch of its Desktop Overlay, a new product designed to provide continuous, real-time guidance for compliance operations and data protection directly at the user interface level, as a personal compliance assistant. Built for highly regulated and government agencies, the Desktop Overlay runs at the edge and preemptively warns users of sensitive data exposure while they are writing, before the data is sent to third-party models, external systems, or leaves device endpoints  – and requires no integration.

As AI adoption accelerates across everyday workflows, organizations face a growing challenge: sensitive information is increasingly shared unintentionally through chat tools, AI assistants, email, and browser-based applications. Traditional Data Loss Prevention (DLP)  tools rely on post-exposure audits, endpoint monitoring, or reactive controls that introduce friction and often fail to stop human error in the moment. Polygraf AI’s Desktop Overlay addresses this gap.

Data Protection at the Edge.

Operating directly at the desktop interface, across all applications, the Overlay identifies and flags sensitive information within 100 milliseconds, as users type. Using intuitive color-coding, it highlights confidential data, such as employee IDs or contact information, in yellow, and critical regulatory data, like Social Security numbers, API keys, or protected health information, in red, providing immediate visual feedback so users can correct mistakes before data leaves the organization.

Unlike legacy DLP systems, the Overlay does not wait for data to be transmitted or logged. It proactively highlights sensitive content in real time using Polygraf’s task-specific Small Language Models. These models run entirely within customer infrastructure, requiring as little as 1.3 GHz CPU and 8GB RAM while consuming just 40-120MB RAM giving organizations complete control, visibility, and auditability over AI interactions. 

The result is a shift from reactive enforcement to continuous protection and education.

Additionally, with the Overlay, Polygraf provides real-time behavioral training for employees. Rather than blocking workflows or relying solely on annual compliance trainings, the Desktop Overlay serves as an always-on security coach. As employees see real-time highlighting across email, chat, AI tools, and internal systems, they develop a practical understanding of what constitutes sensitive information within their organization. Over time, this builds lasting security awareness while reducing accidental exposure. During the pilot testing, customers saw up to a 72% decline in their DLP (Data Leakage Prevention) triggers within 4 weeks of Overlay adoption. 

For organizations operating under SOC2, HIPAA, GDPR, NIST-RMF, or other compliance frameworks, the Overlay combines immediate safeguards with long-term improvements in workforce behavior. It enables productivity while strengthening governance.

This shift toward preemptive control is becoming imperative as organizations struggle to govern  autonomous AI deployments. According to Gartner, “By 2027, 40% of agentic AI projects will be canceled due to high costs, unclear value, and inadequate controls.” Polygraf AI directly addresses the “controls” gap by embedding security into the user’s natural workflow, ensuring AI initiatives move from pilot to production safely.

Over the past year, Polygraf AI has expanded its footprint across the defense, financial services, insurance, and healthcare sectors, where data sovereignty and compliance are mission-critical. The company’s premise-agnostic AI Behavioral Usage Control Layer provides explainable, auditable controls that align with strict regulatory and operational requirements, offering organizations a practical alternative to opaque, cloud-dependent AI security tools.

With the launch of the Desktop Overlay, Polygraf extends its AI security platform directly to the individual user, embedding protection into daily workflows without disrupting productivity. The company will showcase the Desktop Overlay and its broader AI usage control platform during the RSAC Conference, where attendees can see how the technology protects AI interactions in real time across enterprise environments.

Polygraf AI, based in Austin, Texas, announced the closing of their $9.5M seed round led by Allegis Capital and participation from Alumni Ventures, DataPower VC, Domino Ventures and previous investors to accelerate their mission to bring clarity and trust to enterprise AI. The latest round of funding will fuel product expansion, R&D, and go-to-market efforts focused on enterprise, defense and intelligence sectors. This investment in Polygraf AI comes at a critical moment for AI and cybersecurity intersection as high-stakes environments are leaving black-box AI solutions in-search for on-prem, explainable and auditable AI tools.

Technology pioneer Yagub Rahimov, co-founder and CEO of Polygraf AI, announced the company’s new funding today at the Techcrunch Disrupt in San Francisco to an audience of investors, business leaders, startup-founders and AI innovators.

As enterprises accelerate AI adoption to automate workflows, organizations face unprecedented risks from data leakage, shadow AI operations, deepfakes, and other synthetic threats. Polygraf’s proprietary Small Language Models (SLMs) offer an innovative multi-dimensional AI Security layer, one that protects not only data, but also the integrity of decisions, communications, and content produced by AI systems. Gartner, Inc. predicts that by 2027, organizations will implement small, task-specific AI models, with usage volume at least three times more than those of general-purpose large language models (LLMs).

Over the past year, Polygraf AI has experienced rapid growth across defense, financial services, insurance and healthcare niches, where data privacy and compliance are paramount. Running on as little compute power as 8Gb Ram and 1.3 Ghz CPU, Polygraf’s locally deployed AI modules have been credited with reducing deepfake fraud attempts, exposing insider risks, and providing actionable intelligence in mission-critical environments.

Polygraf’s innovations have been recognized by major industry events and media. In 2025, Polygraf AI was named Best in Show at SXSW, Best Insurtech/Fintech at Summerfest Tech, and recognized as the Top AI & Data Product by Products That Count. The company was also recently selected as one of the Top 10 Cybersecurity Startups at TechCrunch’s 2025 Battlefield 200, joining the ranks of the world’s most promising early-stage innovators

Security and compliance teams face growing regulatory pressure and a major increase in AI-driven attacks; Polygraf AI addresses these challenges with its proprietary SLM stack. These SLMs not only detect risks but also explain their decisions, support compliance audits, and align with strict data-sovereignty requirements. With this funding round, the company aims to expand their MSP (Managed Services Providers) & SI (System Integrators) base and to bring SLM’s to more enterprises.
