Problem / agitation / control

A gateway evaluation must cover access, routing, safety, cost, and evidence.

Provider compatibility alone does not resolve master-key exposure, application access, budget enforcement, sensitive-data policy, or durable call accountability.

Model route

Select provider deployments by alias, health, fallback order, rate, and budget state.

Virtual-key access

Keep vendor master credentials encrypted while applications receive revocable broker keys.

Gateway guardrails

Inspect request and response text for PII, secrets, and denied content by scope.

Durable evidence

Record scope, provider, model, tokens, spend, latency, policy decisions, and outcome.

Control capability matrix

Gateway controls must work as one operating path.

Compare the documented LiteLLM product focus with verified Agent Access Manager gateway capabilities.

Control domain	Enterprise requirement	LiteLLM	Agent Access Manager
Gateway	Multi-provider LLM routing and fallback Maintain provider resilience without changing application endpoints.	Native Multi-provider proxy routing, retry, and fallback are documented core capabilities.	Native in current source Alias-based model routing, load balancing, health cooldown, and cross-vendor fallback are implemented in the gateway path.
Gateway	Virtual access keys, budgets, and rate policy Separate application access from provider credentials and constrain spend.	Native Virtual keys, teams, budgets, and rate limits are documented gateway features.	Native in current source Revocable virtual keys, scoped token and currency budgets, and distributed RPM/TPM limits are implemented.
Governance	Organization, team, and project scopes Attach access, budgets, rate limits, and guardrails to accountable enterprise scopes.	Native Teams, users, organizations, and key metadata provide documented gateway governance context.	Native in current source Virtual keys carry organization and optional team/project membership through the governance scope chain.
Security	Pre-call and post-call guardrails Apply consistent PII, secret, and denylist policy before prompts leave and before responses return.	Native Pre-call and post-call guardrail integrations are documented gateway capabilities.	Native in current source Per-scope, per-direction detectors support allow, flag, redact, and block decisions.
Credentials	Encrypted vendor credentials behind virtual keys Keep master LLM vendor credentials out of applications while preserving provider choice.	Native Provider credentials are centralized behind gateway-issued virtual keys.	Native in current source Provider credentials are AES-256-GCM encrypted at rest and resolved only for the selected upstream route.
Evidence	Call-level audit, usage, and security evidence Connect virtual key, scope, provider, model, tokens, cost, guardrail result, latency, and outcome.	Native gateway telemetry Model request logs and spend context are documented; validate retention, export, and security analytics requirements.	Native in current source Postgres is the durable audit and usage record; optional SIEM and SOAR consume normalized governance events.

Migration path / controlled evaluation

Evaluate the operating model without a blind rewrite.

Start from the routes, providers, applications, and controls your platform team already runs. Then test virtual-key mapping, aliases, limits, guardrails, and evidence against explicit acceptance criteria.

Architecture FAQ

Agent Access Manager vs LiteLLM

Is Agent Access Manager a LiteLLM fork?+

No. Agent Access Manager is a separate Java and Spring Modulith on-prem gateway with its own provider adapters, routing, governance, analytics, SIEM, and SOAR modules.

Can LiteLLM and Agent Access Manager coexist?+

A phased evaluation can keep an existing proxy while selected applications move to an Agent Access Manager endpoint and virtual keys. Final topology depends on client compatibility and operational ownership.

What is the main architectural difference?+

Both cover LLM gateway concerns. Agent Access Manager is one modular Spring Boot deployable with Postgres as the durable system of record and optional OpenSearch, Valkey, and Keycloak capabilities.
