SikkerKey

Product: SikkerKey is a secrets manager and vault for application and infrastructure credentials.
Machine authentication: Machines authenticate by signing each request with an Ed25519 private key that remains on the host.
Secret types: The platform supports standard, structured, managed, leased, certificate, canary and TTL secrets.
Integrations: SikkerKey integrates through its CLI, SDKs or signed HTTP with CI/CD, containers, app platforms, serverless functions, servers and on-premise systems.
SDKs: Official SDKs are available for Go, Python, Node.js, .NET, Kotlin and PHP.
CLI platforms: The packaged CLI supports Linux x64 and ARM64, macOS Intel and Apple Silicon, and Windows x64.
AI access: Its MCP server gives AI agents a separate identity class that cannot retrieve plaintext secret values.
Encryption: Secrets use three-layer envelope encryption with per-secret AES-256-GCM data keys, per-project master keys and a separate root key.
EU hosting: SikkerKey says its vault, secrets and audit trail stay in the European Union and are operated from Denmark.
