Polygraf AI

Polygraf AI is an enterprise AI security and zero-trust governance platform for regulated organizations that need to control how employees, agents, and AI systems handle sensitive data.

Key capabilities include:

• Real-time inspection, detection, and redaction across AI tools and enterprise channels (including email, browsers, and Slack) to prevent PII, credentials, and regulated data from leaving security boundaries.
• Desktop Overlay guidance that flags sensitive information in about 100 ms with color-coded severity (for example, confidential vs. critical data) to reduce accidental disclosure during day-to-day work across applications.
• Secure LLM proxy workflows that remove confidential fields before sending prompts to external models (such as ChatGPT or Claude) and restore data after processing, supporting safer use of third-party LLMs.
• API-first deployment for developers, with containerized options that run air-gapped, zero-trust, or cloud environments (Kubernetes/Docker and major clouds), plus audit logs, shadow AI visibility, and real-time threat detection for prompt injection, jailbreaking, and data exfiltration.

Pricing: Freemium; Free tier (2.5K monthly tokens), Premium at $41.63/month (billed yearly), and API Agent at $5.00/month (plus usage fees). Custom pricing is available for Enterprise.

What makes it notable: Polygraf uses a proprietary for explainable, auditable governance, supports deployments for sensitive government data handling, and has reported customer outcomes including up to a after Desktop Overlay adoption.
