An ultra-low-latency reverse proxy that intercepts, secures, and optimizes every LLM transaction inside your VPC — with zero changes to existing application code.
Developers change a single environment variable. Cairn runs as a Kubernetes service in your cluster, speaking the native wire protocol of every major provider. No SDK changes. No wrappers. No migration risk.
# Before: unmanaged, direct to providerimport boto3 client = boto3.client( 'bedrock-runtime', region_name='us-east-1' )# After: routed through Cairn (zero code changes)
Three-layer defense
Intercepts prompts and matches against verified enterprise data caches. Known queries bypass LLM inference entirely — reducing per-call cost to $0.00.
Routes tasks to the cheapest capable model first. Escalates to frontier models only when confidence is low — automatically, without developer intervention.
Every response is evaluated before it reaches users. Non-compliant outputs are blocked and every decision is signed into an immutable audit certificate.
Cairn deploys as a standard Kubernetes service — not a sidecar. Traffic is intercepted via a Mutating Admission Webhook. Ships with a Helm chart, full NetworkPolicy manifests, and RBAC config. Works anywhere Kubernetes runs.
Cairn mirrors VPC egress to discover every hidden AI call leaving your perimeter — including calls from teams who never told you they were using AI. No code changes required for detection.
Works with your existing providers
Kubernetes-native. Deploys anywhere.
Cairn runs as a sidecar or gateway inside your existing Kubernetes environment. No agents to install, no traffic leaves your network.
