AI Identity vs Portkey

Portkey is a powerful LLM gateway for routing and observability. AI Identity adds what Portkey is missing: per-agent identity, tamper-proof audit trails, and compliance-ready governance.

Where Portkey Falls Short for AI Agents

Portkey optimizes LLM calls. It does not govern the agents making them.

No Per-Agent Identity

Portkey uses team-level API keys shared across agents. When one key leaks, every agent is compromised. You cannot revoke access for a single agent without rotating keys for the entire fleet.

No Tamper-Proof Audit Chain

Portkey logs requests but does not cryptographically chain them. Logs can be altered without detection, making them inadmissible for compliance audits or legal disputes.

No Compliance Dashboards

Portkey offers no built-in assessments for EU AI Act, SOC 2, or NIST AI RMF. Teams must build their own compliance reporting layer on top of raw logs.

No Chain-of-Thought Forensics

When an agent misbehaves, Portkey cannot replay the reasoning steps that led to the action. You see the input and output, but not the decision-making process in between.

Why Teams Choose AI Identity

Purpose-built identity and governance for autonomous AI agents.

Cryptographic Agent Identity

Every agent gets a unique aid_sk_ key tied to a verifiable identity. Revoke, rotate, or scope credentials per agent without disrupting your fleet.

Immutable Audit Trails

HMAC-SHA256 hash-chained logs that cannot be altered after the fact. Every action is cryptographically linked to the previous one, creating courtroom-grade evidence.

Built-In Compliance

One-click assessments for EU AI Act, SOC 2 Type II, and NIST AI RMF. Export audit-ready reports instead of building compliance tooling from scratch.

Fraction of the Cost

AI Identity Pro starts at $79/mo with up to 50 agents. Portkey Pro is $59.99/mo but lacks identity, compliance, and forensics — the features that matter most in production.
