F5 AI Guardrails deploys as a proxy between users and AI models. Wormke describes it as being inserted as a proxy layer at the “front door” of AI interaction, between AI applications, users and agents. It intercepts prompts before they reach the model and analyzes outputs before they return to users. The system applies policy rules to actual content rather than transport-layer characteristics.
Policy enforcement covers several categories. Guardrails blocks prompts that attempt jailbreaks or injection attacks, scans outputs for sensitive data patterns, and enforces compliance requirements including GDPR and the EU AI Act.
Red Team automation creates continuous testing
AI Red Team automates adversarial testing against AI systems. It maintains a database of attack techniques that grows by 10,000 entries monthly as researchers discover new vulnerabilities.
Results from Red Team testing feed directly into Guardrails policies. When Red Team discovers a vulnerability pattern, security teams create corresponding guardrails to block similar attacks in production.
“It’s a very synergistic pairing wherein with AI Red Team you can send a team of agents to discover vulnerabilities in AI systems, and with AI Guardrails you can transform those insights into threat-informed defenses,” Wormke said.
NGINXaaS delivers enterprise load balancing as a managed service
F5 acquired NGINX back in 2019 and has been expanding the capabilities of the web server platform ever since.
