Guardrails for LLM applications and AI agents that are designed, built and tested by a team that spends its time trying to break them.
Almost every AI application ships with some form of guardrail: a system prompt telling the model what not to do, a content filter from the model provider, or a keyword block list. In our testing, these controls are often bypassed within minutes using prompt injection, role-play, encoding tricks or instructions hidden in documents the model reads. Once past them, an attacker can extract data, misuse tools or make the application say things that damage your brand.
White Knight Labs AI Safety & Guardrail Engineering takes a layered approach. We design controls that do not depend on the model obeying instructions, implement them with your engineering team, and test them with the same adversarial techniques our red team uses against production AI systems.
Detection and handling of prompt injection, jailbreak attempts and malicious content in user input and in retrieved documents, emails, web pages and files the model processes.
Filtering and validation of model output for sensitive data, policy violations, unsafe content, hallucinated references and malformed structured data before it reaches users or downstream systems.
Allowlists, parameter validation, rate limits and human confirmation steps for agent actions, so that a manipulated model cannot take high-impact actions on its own.
Permission-aware retrieval and response filtering that enforce the user’s actual access rights, independent of what the model is asked to do.
Enforcement of business rules about what the application should and should not discuss, tuned to reduce false positives that frustrate legitimate users.
Defined behavior when a guardrail triggers or a model provider is unavailable, including user messaging, escalation to a human and logging for review.
We begin with a threat model of your application: who uses it, what data and tools it can reach, and what a successful attack would look like. From there we select and design the right combination of controls, which may include provider features, open-source guardrail frameworks, custom classifiers and deterministic checks in your application code.
Every control is tested adversarially before we consider it done. We maintain a growing library of attack techniques and evaluation datasets, and we can integrate these into your CI/CD pipeline so guardrails are regression-tested whenever prompts, models or code change.
We map the application’s data, tools, users and abuse cases, and define what the guardrails must prevent.
We design a layered control architecture and recommend tools that fit your stack, latency budget and cost constraints.
We build or configure the controls alongside your engineers, with documentation and tuning guidance.
We attack the finished controls, measure bypass rates and false positives, and refine until they meet agreed thresholds.
Optionally, we set up automated evaluation suites that run in your pipeline and alert when a change weakens protection.
