How It Works

1

Add Your Key

Store your Email API key in ShieldKey's AES-256-GCM encrypted vault. It's never stored in plaintext.

2

Issue Shield Tokens

Generate revocable proxy tokens for each team member. Set IP restrictions, spend limits, and rate caps per token.

3

Proxy Requests

Your team uses Shield Tokens instead of the real key. ShieldKey decrypts in-memory and forwards to the provider.

4

Revoke Instantly

When someone leaves, revoke their token in one click. No key rotation, no downtime, no redeployments.
