What is CalypsoAI?
CalypsoAI is a pioneering AI security company founded in 2018 that provides the only full-lifecycle platform to secure AI agents and applications at the inference layer. Headquartered in Dublin, Ireland with operations in New York, CalypsoAI has established itself as a leader in enterprise AI security through its innovative 'Agentic Warfare' approach to protecting organizations from evolving AI threats. The company's technology deploys a comprehensive 'test–defend–observe' stack that protects applications, APIs, models, and agents throughout the AI lifecycle.
CalypsoAI has earned significant industry recognition, including being a Top-Two Finalist in the 2025 RSAC Innovation Sandbox contest and one of Fast Company's Most Innovative Companies in AI for 2025. The company secured over USD 40 million in venture funding from prominent investors including Paladin Capital Group, Lockheed Martin Ventures, and Hakluyt Capital, demonstrating strong confidence in its security-first approach to AI.
In September 2025, F5 Networks acquired CalypsoAI for USD 180 million, positioning F5 as the first major vendor to embed comprehensive AI-native security directly into application delivery infrastructure. CalypsoAI's technology is trusted by global enterprises including Palantir and SGK, and the acquisition enables F5 to integrate CalypsoAI's enterprise-ready security capabilities into the F5 Application Delivery and Security Platform, providing enhanced protection for AI-powered applications at scale.
