F5 AI Guardrails
Define and deploy agile data security, threat management, and governance for AI models, apps, and agents.
Secure AI systems and connected data—from pilot to production
Threat actors discover new ways to attack, models find new paths to harmful outputs, and users find new ways to break policy. F5 AI Guardrails secures AI models and agents against malicious threats, data leakage, and harmful outputs with industry leading efficacy and unmatched deployment flexibility.
Benefits
Combat adversarial attacks
Safeguard AI systems from evolving threats like prompt injection and jailbreaks
- Prompt Injection Defense: Protect against prompt injection attacks, data exfiltration, and jailbreak attacks without excessive false positives
- Threat-Informed Protection: Backed by the preeminent AI threat library with over 10,000 attack patterns added monthly, F5 Labs Threat Research ensures threat protection outpaces emerging attack techniques
- CASI Model Risk Leaderboard: Inform model selection with detailed testing into the risk profiles unique to the most prominent models

Secure AI data
Detect and prevent data leakage, compliance failures, and policy violations at runtime
- Model-agnostic policy enforcement: Secure the millions of public and proprietary models with consistent policy enforcement and privacy
- Custom policy creation: Rapidly create bespoke, policy-driven security controls tailored by use case, region, and industry through an intuitive natural language interface
- Day 1 Compliance Controls: Expert-built guardrails for PII leakage, EU AI Act alignment, PCI, and PHI protection

Govern responsible AI usage
Obstruct harmful outputs, and enforce restrictions on model and agent privileges
- F5 AI Guardrails helps teams adapt security as requirements change
- Secure AI Agents: Prevent excessive agency and privilege escalation by enforcing guardrails on agent actions and tool use
- Content Moderation: Align AI outputs to enterprise-specific definitions of biased, toxic, or harmful content

Simplify AI observability
Maintain continuous visibility and traceability across all models, users, and agent interactions
- Audit-ready logging: Explain and trace every enforcement action with detailed analysis and guardrail attribution
- Agent Visibility: Observe and log system prompts, instructions, model reasoning, and tool calls for single- or multi-agent systems.
- Performance Dashboard: Continuously monitor performance metrics, usage trends, and recent enforcement actions in a unified dashboard or exported to a third-party SIEM

FAQs
AI guardrails are frameworks of policies, technologies, and controls designed to ensure that AI systems operate securely and responsibly within defined boundaries. In the enterprise context, this includes mitigating risks such as adversarial attacks, data leakage, and compliance failures. The requirement for AI guardrails must go beyond merely preventing undesired behavior to proactively flagging risks, protecting sensitive data, and enabling trust across complex, multi-model systems.
F5 AI Guardrails applies content moderation filters and custom policy controls at runtime to inspect model outputs before they reach users. You can deploy out-of-the-box safeguards or create custom guardrails using natural language to detect and block toxic, biased, or harmful content. If a particular hallucination category has been observed at high frequency, F5 AI Guardrails lets you define rules that constrain model responses to avoid high-risk topics and prevent outputs that deviate from acceptable parameters.
F5 AI Guardrails includes out-of-the-box policy controls aligned to PCI, PHI, and EU AI Act prohibited-risk categories. It secures multiple sensitive data patterns at runtime and logs every enforcement action with transparent reasoning. These audit-ready logs simplify reporting for compliance teams and support enterprise governance requirements.
Model provider guardrails are typically a baseline protection designed to meet the provider’s compliance obligations and risk appetite rather than protections extensible to all enterprise use cases, and risk definitions. In recent SecureIQLab testing of foundational models’ built-in guardrails against sophisticated AI attacks, roughly 13% of attacks were successfully blocked. Model providers may offer limited security controls but the efficacy of those controls does not meet the standards of most enterprise workloads and often restricts those controls to specific models rather than the full breadth of an organization’s AI inventory.
Open-source AI security tools offer a starting point but require significant internal expertise to configure, deploy, and maintain. They're community-driven, which often means slower updates, limited compliance-ready templates, and gaps in audit trails required for regulated industries. Commercial AI security tools provide enterprise-grade capabilities including dedicated threat research, regular updates against emerging attack techniques, and out-of-the-box compliance controls needed for enterprise AI workloads.
