CalypsoAI, founded in 2018, specializes in protecting AI systems against emerging attack methods, including prompt injection and jailbreak attacks.<\/p>\n<p>\u201cAI is redefining enterprise architecture and the attack surface companies must defend,\u201d said Fran\u00e7ois Locoh-Donou, F5\u2019s president and CEO. The company plans to integrate CalypsoAI\u2019s capabilities into its Application Delivery and Security Platform to create what it describes as a comprehensive AI security solution.<\/p>\n<p>Companies are embedding AI into products and operations at an unprecedented pace, but this rapid adoption has created compliance gaps and heightened regulatory scrutiny. CalypsoAI addresses these challenges through what the company calls \u201cmodel-agnostic\u201d security, providing protection regardless of which AI models or cloud providers enterprises use. <\/p>\n<div class=\"ad ad--inline_1 \">\n<div class=\"ad__inner\"> <span class=\"screen-reader-text\">Advertisement<\/span> <\/div>\n<\/div>\n<p>The platform conducts automated red-team testing against thousands of attack scenarios monthly, generating risk assessments and implementing real-time guardrails to prevent data leakage and policy violations.<\/p>\n<p>\u201cEnterprises want to move fast with AI while reducing the risk of data leaks, unsafe outputs, or compliance failures,\u201d said CalypsoAI CEO Donnchadh Casey. The company\u2019s approach focuses on the inference layer where AI models process requests, rather than securing the models themselves.<\/p>\n<p>The acquisition comes during <a href=\"https:\/\/cyberscoop.com\/zscaler-red-canary-acquisition\/\">a flurry<\/a> <a href=\"https:\/\/cyberscoop.com\/varonis-slashnext-acquisition-ai-email-security\/\">of similar moves<\/a> <a href=\"https:\/\/cyberscoop.com\/rubrik-predibase-acquisition-agentic-ai\/\">by established companies<\/a> in the cybersecurity space that are looking to <a href=\"https:\/\/cyberscoop.com\/cato-networks-acquires-ai-security-startup-aim-security\/\">add AI-powered offerings<\/a> to their customers. <\/p>\n<p>F5 has also been active this year with what it considers strategic purchases. The company acquired San Francisco-based Fletch in June and observability firm MantisNet in August, demonstrating a pattern of building capabilities through acquisition rather than internal development.<\/p>\n<p>The deal is expected to close by Sept. 30. <\/p>\n<p><\/body> <\/p>\n<footer class=\"single-article__footer\" readability=\"3.9423407917384\">\n<div class=\"author-card\" readability=\"14\">\n<div class=\"author-card__avatar\">\n<figure class=\"author-card__image-wrap\"> <img data-recalc-dims=\"1\" decoding=\"async\" class=\"author-card__image\" src=\"https:\/\/i0.wp.com\/ddi.mohflo.net\/wp-content\/uploads\/2025\/09\/f5-to-acquire-ai-security-firm-calypsoai-for-180-million-1.jpg?w=640&ssl=1\" alt=\"Greg Otto\"> <\/figure>\n<\/p><\/div>\n<p><h4 class=\"author-card__name\">Written by Greg Otto<\/h4>\n<p> Greg Otto is Editor-in-Chief of CyberScoop, overseeing all editorial content for the website.
