Zero-Trust Infrastructure for Agentic Workflows
Autonomous agents are your biggest assets—and your biggest risks. Ephos secures sensitive API credentials using Zero-Knowledge Architecture, scoped tokens, and cryptographic revocation.
The NHI Gap
Traditional secret managers weren't built for autonomous code.
Credential Leakage
Autonomous agents and IDE extensions often require broad API access. One compromised log file or misconfigured agent means your master secrets are gone.
Ulimited Blast Radius
Most API keys provide full access. A raw OpenAI or GitHub key has no intrinsic guardrails. If stolen, an attacker has full access to your account until you manually rotate the key.
Zero Traceability
Who used the key? When? To hit which endpoint? Legacy logs don't provide agent-level attribution.
How It Works
Ephos creates a secure execution tunnel between your agent and the target API.
Raw keys are encrypted locally and stored as Phantom Keys. Our platform operates on a zero-knowledge basis; we never see your plaintext secrets.
Provision scoped Ephos Tokens for specific agent identities, restricted by domain and TTL.
Requests are processed in Ephemeral RAM. Credentials exist for milliseconds before being scrubbed from volatile memory.
Security Features
Engineered for the highest compliance and security standards.
Identity Tokenization
Leverage 1:N tokenization to scale security. Derive identity-specific Ephos Tokens from a single Phantom Key to enforce granular permissions without risking raw credentials.
Cryptographic Rotation
Terminate access instantly. Use the UI or CLI to revoke specific agent tokens without the need to rotate your underlying Master Identity Secrets.
Domain Whitelisting
Lock down agent communication. Ensure your data stays where it belongs by restricting API calls to authorized providers and blocking unauthorized egress.
Forensic Audit
Achieve total operational visibility. Every API request is logged and mapped to a unique agent identity for immutable auditing and compliance.
Threat Model
Why Ephos is objectively safer than standard integrations.
Threat: Prompt Injection
An attacker attemps to steal an Ephos Token from an agent's memory or config.
Ephos Mitigation
Agent only has scoped tokens; master key is never exposed and all responses are scrubbed.
Threat: Server Compromise
An attacker gains access to the Ephos database.
Ephos Mitigation
Zero-knowledge storage; encrypted blobs are useless without user passphrase.
Threat: Token Theft
Stolen key used for abuse.
Ephos Mitigation
Domain whitelisting prevents use on unauthorized endpoints. Tokens can be revoked instantly upon suspected misuse.
Use Cases
Deploy with confidence across any workflow.
Autonomous Agents
Safely give agents access to Stripe, AWS, or Slack without risking the entire account.
Team Delegation
Let developers use production keys via the proxy without them ever seeing the raw secret.
MCP Integration
Standardized protocol for connecting AI tools with enterprise-grade security.
