LiteLLM vs Portkey vs AWS GenAI Gateway: Centralized AI Gateway Comparison for Security Teams
A practical comparison of LiteLLM, Portkey, and AWS multi-provider GenAI gateway patterns for security teams centralizing model access, policy, logging, and token controls.
LiteLLM vs Portkey vs AWS GenAI Gateway
Security teams should not let every product group manage its own model keys, logging, budgets, and provider policy. A centralized AI gateway gives the organization one control plane for model access, cost discipline, auditability, and safer agent adoption.
Quick comparison
| Option | Best fit | Security value | Watch-outs |
|---|---|---|---|
| LiteLLM | Teams that want open, provider-flexible routing and policy | Virtual keys, budgets, routing, logging, caching, and model abstraction | Needs careful deployment, secret handling, and gateway hardening |
| Portkey | Teams wanting a managed AI gateway and observability layer | Centralized logs, routing, guardrails, analytics, and provider controls | Review data retention, tenant boundaries, and enterprise controls |
| AWS GenAI Gateway pattern | AWS-heavy organizations standardizing multi-provider access | Private architecture, AWS-native controls, IAM, networking, and operational ownership | Requires more engineering ownership than a pure SaaS approach |
What security teams should require
- Centralized API keys or virtual keys with owner, purpose, and expiration.
- Provider allowlists by team, app, environment, and data sensitivity.
- Prompt and response logging with redaction rules and retention limits.
- Budget controls to prevent runaway agent loops and uncontrolled token spend.
- Clear separation between development, preview, and production model access.
- Gateway-level policy for sensitive data, code, secrets, regulated data, and customer content.
- Incident response procedures for leaked keys, malicious prompts, and compromised agents.
Recommended decision
Use LiteLLM when engineering teams need flexibility and are ready to operate the gateway securely. Consider Portkey when managed observability and faster adoption matter more. Use an AWS-native gateway pattern when the organization already standardizes on AWS controls and wants deeper network, IAM, and logging ownership.
The right answer is less about brand and more about operating model. If the gateway has no owner, no logs, no budget policy, and no incident path, it is not a security control. It is just another proxy.
