About
Calypso AI — rebranded as F5 AI Guardrails following its acquisition by F5 — is a comprehensive AI security platform designed to protect AI models, applications, and agents at runtime. As enterprises scale AI deployments from pilot to production, the attack surface grows significantly, and Calypso AI addresses this by providing dynamic, agile guardrails that adapt to evolving threats and shifting business needs. The platform combats adversarial attacks such as prompt injection and jailbreaks, allowing security teams to choose from preset guardrail policies or craft bespoke rules tailored to specific use cases. It actively detects and prevents data leakage, compliance violations, and policy breaches before they impact the business. Governance capabilities ensure responsible AI usage by enforcing restrictions on model and agent privileges, blocking harmful outputs, and supporting regulatory compliance frameworks. Calypso AI also offers deep AI observability, giving teams continuous visibility and traceability across every AI interaction — a critical capability for auditing, incident response, and risk management. It translates discovered vulnerabilities into dynamic protections that remain effective as new models are introduced or operational requirements change. The solution is purpose-built for security engineers, AI/ML operations teams, and enterprise architects who need to maintain a strong security posture without sacrificing the workflow automation benefits that AI delivers. It integrates within F5's broader application delivery and security ecosystem, making it a natural fit for organizations already leveraging F5 infrastructure.
Key Features
- Adversarial Attack Protection: Defends AI systems against prompt injection, jailbreaks, and other evolving adversarial threats using preset or custom guardrail policies.
- Runtime Data Security: Detects and prevents data leakage, compliance failures, and policy violations in real time as AI models and agents process requests.
- AI Governance & Compliance: Enforces responsible AI usage by restricting model and agent privileges, blocking harmful outputs, and aligning with regulatory requirements.
- Continuous AI Observability: Provides end-to-end visibility and traceability across all AI interactions for auditing, monitoring, and incident response.
- Dynamic Policy Management: Translates discovered vulnerabilities into adaptive protections that update automatically as new models or business needs are introduced.
Use Cases
- Protecting large language model (LLM) APIs from prompt injection and jailbreak attacks in production environments
- Enforcing data privacy and compliance guardrails to prevent PII or sensitive data leakage through AI responses
- Monitoring and auditing all AI agent interactions for traceability and regulatory reporting
- Governing agentic AI workflows by restricting model and agent privileges to prevent privilege escalation or misuse
- Dynamically updating AI security policies as new models are deployed or threat landscapes evolve
Pros
- Comprehensive Threat Coverage: Addresses a wide range of AI-specific attack vectors — from prompt injection to data exfiltration — in a single unified platform.
- Flexible Guardrail Configuration: Teams can use out-of-the-box policies or define custom guardrails tailored to specific use cases and risk tolerances.
- Enterprise Ecosystem Integration: Backed by F5's robust application delivery and security infrastructure, enabling seamless integration with existing enterprise deployments.
Cons
- Enterprise-Focused Pricing: As an F5 enterprise product, pricing is not publicly disclosed and may be out of reach for smaller teams or startups.
- Complexity for Smaller Deployments: The platform's breadth of features and enterprise architecture may be more than necessary for lightweight or early-stage AI use cases.
