Capabilities

LLM & Security Gateway capabilities

App / agent: a request with PIIPII detector: names, phones, addresses, cardsObfuscation: PII → stable tokens + session mapGateway: routing, budgets, semantic cache, guardrailsLLM provider: receives only anonymized textModel response: with tokens instead of PIIDe-obfuscation: tokens → original values via the session mapUser: a response with real data; PII never left the perimeter

A two-way PII protection contour in LLM & Security Gateway. The application request passes through a PII detector that replaces personal data with stable tokens and stores a session mapping. The anonymized request, with routing, budgets and cache applied, goes to the chosen LLM. The model response returns with the same tokens, is de-obfuscated via the session map — tokens are substituted back to their original values — and the user gets a response with real data that never left the perimeter and never entered the provider's logs.

PII obfuscation before sending to the model

Names, phones, addresses and card numbers are replaced with stable tokens before sending; the model and its logs never get real customer data, removing GDPR fine risk

De-obfuscation in the response

Tokens in the model's response are restored to original values via a session map — the user sees real data that never left the perimeter

Model routing by price and quality

Cheap requests go to light models, complex ones to frontier; costs drop 45-85% with no noticeable quality loss

Budgets and limits per team and project

Token limits per key, team and project stop overspend before the provider bill — an end to surprises of 40% over forecast

Fallback and load balancing across providers

If one model fails or slows down, traffic shifts automatically to a backup — the AI service does not go down with the provider

Observability and cost attribution

Every request is logged with model, tokens, latency and cost via OpenTelemetry — you see who spends how much and where quality degrades

Semantic cache

Repeated requests are served from cache (40%+ hit rate in production) — lower bill and latency with no loss of answer quality

Unified key and access management

Provider keys are stored in the gateway; teams get virtual keys with instant revocation — secrets never leak into application code

Guardrails on input and output

Prompt injection detection and content filtering before and after the model reduce leak risk and toxic responses in production

Approach

How we implement LLM & Security Gateway

Without modifying the core

We don't fork or patch the LLM & Security Gateway core. LLM & Security Gateway stays on the standard, upgradable version — we move business logic into separate microservices alongside it, so platform updates don't break your customizations.

International Standards, Not Homegrown Hacks

Where a mature international solution exists, we use it instead of inventing our own protocol or platform. Before writing code, we study how the problem is already solved in the industry.
