Both LiteLLM and Kong provide baseline AI security controls, including prompt guardrails, filtering, and PII-related protections.
Kong's AI PII Sanitizer enforces DLP at the gateway across 20+ PII categories and 12 languages, on both prompts and responses, with synthetic replacement, optional restoration, and block-on-detect under one audit trail. This provides customers with unified platform-level control and makes it easier to mitigate any compliance gaps.
LiteLLM relies on Presidio plus a catalog of partner guardrails like Aporia, Lakera, Bedrock, and PANW Prisma AIRS, but behavior and audit detail vary by integration. This means LiteLLM teams have to reconcile those differences or accept inconsistent DLP across models and consumers.
Even more differences start to show up once the gateway becomes shared infrastructure, including how the platform handles identity, access, and policy across production AI traffic.
Kong supports a broader enterprise auth surface, including OIDC, mTLS, WebSocket OIDC and mTLS at handshake, ACL enforcement, and multi-cloud IAM integrations across AWS, Azure, and GCP. LiteLLM is more centered on API key and bearer-token access. That distinction becomes notable for service accounts, non-human identities, and organizations that already need to fit AI traffic into an existing IdP or IAM model.
Finally, Kong keeps more of the safety and governance model in the gateway and platform layer itself, including NeMo Guardrails, ai-prompt-guard, and a custom guardrails framework for third-party APIs. LiteLLM does provide safety controls too, but it leans more on integrations, provider controls, and project or key-level guardrail assignment.
For buyers evaluating security in production, the more useful distinction is not whether a safety feature exists, but whether auth, guardrails, and policies can be enforced centrally across the core traffic patterns of the business.
