Vireo Sentinel is an AI visibility and data privacy platform for teams of any size. A lightweight browser extension monitors how your team uses ChatGPT, Claude, Perplexity, Gemini, and 40+ additional AI platforms. When someone is about to share sensitive data with an AI tool, they see a real-time intervention with four options: cancel the prompt, redact the sensitive content, edit their message, or override with a business justification. Detection uses deterministic pattern matching across 100+ sensitive data types including personal information, financial data, credentials, and legal content. No AI is used for detection. Employee data is never sent to a cloud service for analysis. Everything is processed in the browser. The admin dashboard shows usage patterns, risk trends, platform breakdowns, and activity heatmaps. One-click compliance reports map to EU AI Act, ISO 42001, and Australian Privacy Act requirements. Pricing starts at $55 AUD/month for up to 5 users with a sliding scale for larger teams. 14-day free trial available.
