What Acuvity does
Acuvity was an AI-native security and governance company that built the RYNO platform to help enterprises safely adopt generative AI. Founded in 2023 by Satyam Sinha and Antoine Mercadel and headquartered in Sunnyvale, California, the company provided runtime visibility, intent-based monitoring, and policy enforcement across AI interactions including copilots, autonomous agents, embedded AI in SaaS applications, and Model Context Protocol (MCP) servers. Its proprietary intent-based detection technology analyzed prompts and responses to identify adversarial behavior, data oversharing, prompt injection, agentic privilege escalation, and zero-click attacks, while supporting compliance monitoring across GDPR, HIPAA, and SOC 2 frameworks.
The company operated an enterprise subscription model with annual billing and quote-based pricing negotiated at the organizational level, targeting CISOs and security teams through a direct field sales motion with 'Request a demo' as the primary call-to-action. Customer segmentation was horizontal, focused on large enterprises deploying generative AI tools and AI agents, with no publicly named customer logos and no disclosed revenue or ARR figures.
In September 2024 Acuvity emerged from stealth with $9 million in seed funding led by Foundation Capital, scaling to 24 employees by early 2026. On February 12, 2026, Proofpoint acquired Acuvity and rebranded the technology into three product lines: Proofpoint AI Access Security (securing AI usage by people), Proofpoint Agentic AI Security (governing AI agents), and Proofpoint AI MCP Security (enforcing authentication and content inspection at the MCP boundary). Following the acquisition Acuvity operates as a wholly-owned subsidiary with its capabilities distributed through Proofpoint's global channel, technology alliance, and MSP partner networks.
