F5, a global leader in application delivery and security, has announced plans to acquire CalypsoAI, a recognized innovator in enterprise AI security. CalypsoAI’s award-winning platform delivers real-time threat defense, large-scale red teaming, and advanced data security, helping enterprises accelerate the safe adoption of generative and agentic AI. Once the acquisition closes, these capabilities will be integrated into the F5 Application Delivery and Security Platform (ADSP) to create one of the most comprehensive solutions for securing AI inference.
“AI is redefining enterprise architecture—and the attack surface companies must defend,” said François Locoh-Donou, President and CEO of F5. “Traditional firewalls and point solutions can’t keep up. The addition of CalypsoAI will give enterprises the confidence to innovate faster and better protect critical data as they rely on F5 to deliver and secure apps, APIs, and AI models across their environment.”
As enterprises embed AI deeper into products and operations, they face an increasingly complex attack surface spanning applications, agents, APIs, models, and data stores. Traditional security controls are struggling to keep pace with evolving AI-driven threats. At the same time, rising regulatory requirements and the growth of shadow AI adoption are creating new compliance and risk management challenges. Organizations now need a model-agnostic, purpose-built solution that delivers security guardrails for AI while providing unified visibility across their infrastructure.

According to Gartner®’s Market Guide on AI Trust, Risk and Security Management (TRiSM), “The AI TRiSM market is distinguished by its independence from frontier model provider solutions that also support trust risk and security management. Enterprises must retain independence from any single AI model or hosting provider to ensure scalability, flexibility, cost control and trust, as AI markets rapidly mature and change.”
F5’s integration of CalypsoAI is designed to directly address these market needs by enabling:
-
Adversarial threat protection: Real-time defense against prompt injection, jailbreaks, and other emerging AI threats, supported by continuous red-teaming against more than 10,000 new attack prompts monthly to generate accurate risk scores.
-
Data security at runtime: Guardrails to prevent sensitive data leakage and enforce policies while auditing AI interactions across diverse models.
-
Centralized governance and observability: Unified monitoring, policy enforcement, and audit logs to simplify compliance with GDPR, the EU AI Act, and other global standards across hybrid, on-premises, and SaaS environments.
“Enterprises want to move fast with AI while reducing the risk of data leaks, unsafe outputs, or compliance failures,” said Donnchadh Casey, CEO of CalypsoAI. “Our customers rely on us to pressure test AI systems at scale, set inference layer guardrails that adapt as models change, and to gain visibility and auditability across their AI estate. F5 and CalypsoAI are more than the sum of their parts: high performance application delivery and AI security that enable businesses to deliver innovation faster without increasing risk.”
