How AI is used
Eleidon is a security service designed for AI agents using email. While standard protocols like SPF and DKIM verify servers and domains, Eleidon is designed to verify the identity of the agent itself using cryptographic keypairs.
The tool is for developers and operations managers deploying AI agents that handle business tasks via email. It supports agents signing outgoing messages so recipients can verify the sender's identity and check if the content was altered in transit.
For inbound email, the service provides a verification endpoint that returns a confidence score. This may help prevent AI agents from executing commands—such as canceling orders or changing account details—based on fraudulent or spoofed emails.
Buyers should consider their monthly verification volume when choosing a plan, as signing is unlimited but verification is metered. Technical stacks should be checked against available SDKs for Python, TypeScript, or the Model Context Protocol.
Key Features
Outbound Email Signing
Adds a cryptographic header to outgoing emails using a private key, which allows recipients to verify the agent's identity.
Inbound Email Verification
An API endpoint that verifies inbound emails and returns an agent identity and confidence score.
Confidence Scoring
Provides a numerical value indicating the likelihood that a message is authentic and has not been tampered with.
Agent Registration
Supports generating keypairs and registering public keys with claimed inboxes to establish a verified identity.
Developer SDKs
Includes libraries for TypeScript, Python (PyNaCl-powered), and the Model Context Protocol (MCP).
Use Cases
Reducing Risk of Fraudulent Agent Actions
Verifying inbound email authenticity before an AI agent processes a request to help prevent actions based on spoofed addresses.
Authenticating Agent Communications
Signing outbound notifications, such as shipping confirmations, so recipients can verify the message came from a legitimate agent.
Establishing Cryptographic Proof
Using cryptographic identity to maintain a record of which agent sent or received a specific communication.
