Stop unsafe AI outputs inreal time,before it reaches a user.
Block prompt injection, jailbreaks, sensitive-data exposure, and harmful content at the moment they occur. Every policy decision is automatically preserved as evidence.

AI risk happens at runtime. Your controls should too.
Every production AI system can encounter malicious prompts, sensitive data, unsafe tool requests, and harmful outputs. Static reviews and pre-launch testing cannot anticipate every interaction once the system reaches real users.
Organizations need to show which controls were active, how each interaction was evaluated, and what happened when a violation occurred. That evidence must come from the system enforcing the policy, not from documentation assembled afterward.

Documenting a policydoesn't enforce it.
GRC tools document what an AI system is allowed to do, but they do not apply those rules to live inputs, outputs, and agent actions. Traditional security tools can monitor infrastructure, network activity, and sensitive data without evaluating the full context of an AI interaction.
Without runtime guardrails, prompt injection, data exposure, harmful responses, and unauthorized tool use may reach a model or user before security teams can intervene.
No control at the moment of interaction.
Detection often occurs after the request has reached the model or the response has reached the user. Nothing is positioned to inspect and stop the violation inline.
Traditional security controls were not designed for AI behavior.
Infrastructure and data-security tools can detect known threats without fully evaluating prompt injection, jailbreaks, agent actions, model responses, and conversational context.
Protection is inconsistent across AI systems.
A guardrail configured for one application does not protect every model, agent, or provider. Without shared controls, coverage depends on each team remembering to build and maintain its own safeguards.
Enforce policy, not just document it.
Openlayer applies governance policies directly to live AI interactions. Violations are blocked, redacted, escalated, or routed for review, with every decision recorded as evidence.
Guardrails use the same test definitions as evaluation and monitoring. What you test is what you enforce, and evidence is generated automatically.
Real-time protection for every AI interaction
Inline PII/PHI blocking
Detect and block sensitive data in prompts and responses before it reaches a model, external provider, application, or user.
Prompt injection defense
Identify and stop prompt-injection and jailbreak attempts as requests flow through.
Harmful and toxic output filtering
Block toxic, harmful, and malicious content inline based on configurable policy.
Audit evidence by default
Record every policy evaluation, enforcement action, exception, and outcome with a timestamp, system version, owner, and supporting trace.
“For the first time, the same AI policies are being enforced consistently across every team and application.”

Guardrails are real-time checks that inspect AI inputs and outputs as they happen and block sensitive data exposure, prompt injection, jailbreak attempts, and other unsafe behavior before it reaches a model or a user.
A test evaluates a system before or after the fact, on a schedule or in CI/CD. A guardrail intervenes in the moment, in the live request path, before an unsafe input or output goes any further.
Guardrails are built to catch prompt injection attempts, jailbreak attempts, and the exposure of sensitive data such as PII or PHI in prompts, retrieval context, or model outputs.
Guardrails run inline within the request path and are designed to add minimal latency, so they can operate in production without materially changing the user experience.
Guardrail policies can be configured to reflect an organization's own rules, such as which categories of sensitive data to block or which topics a customer-facing assistant should avoid.
Guardrails apply at the point where AI traffic is routed through Openlayer, so they can protect systems regardless of the underlying framework or model provider.
A blocked request or response is logged with the reason it was flagged, giving security and compliance teams a record of what was stopped and why.
Guardrails are commonly enforced through the Gateway, which gives them visibility into traffic across every application and model provider routed through it. They can also be applied directly through the SDK.
Guardrail activity feeds directly into compliance evidence, since a blocked policy violation is recorded the same way a passed or failed test would be.
Pre-launch testing cannot cover every scenario a live system will encounter. Guardrails provide a second layer of protection that continues to enforce policy after a system is already in production.
