Why it matters
Defenders operating LLM applications need practical defense-in-depth patterns because provider safety training alone leaves residual jailbreak and prompt-injection failure modes that reach production traffic.
DeepInspect's blog describes a layered defense pattern for LLM jailbreaks in production, combining input-side classifiers (model-based and rule-based), output-side classifiers that catch leaked system prompts, PII/PHI, unsafe code, and prompt injection aimed at downstream systems, and an identity-aware policy layer that scopes tools and data at the request boundary. The piece frames provider-side safety training as insufficient alone and advocates layered controls that each produce an audit signal.
