Glossary Control and oversight
Guardrails
Technical rules that bound the input, output and actions of a system.
What is Guardrails?
Guardrails are the technical bounds around a model: filters on input and output, permitted and forbidden topics, checks before tool calls, budget and step limits, and fixed output formats. They act outside the model and are therefore auditable and versionable.
They do not replace a risk assessment. Filters can be bypassed, and rules that are too strict make a system unusable. The approach only becomes solid when every guardrail maps to a concrete threat, its effect is measured, and the remaining residual risk is documented.
