Built secureby default

Military-grade encryption, zero-trust architecture, and comprehensive controls — every layer of the stack is hardened out of the box.

Security Layers

Encrypted Storage

  • AES-256 encryption for all sensitive data at rest.
  • Per-tenant encryption keys with automatic rotation.
  • Zero plaintext secrets stored anywhere.

JWT Authentication

  • Short-lived access tokens with secure refresh flow.
  • Signed with RS256; keys rotated automatically.
  • Instant token revocation on logout or ban.

Hardware Binding

  • Licenses bound to device fingerprint (HWID).
  • Cryptographic checks prevent cloning and sharing.
  • Configurable device limits per license.

API Security

  • API keys with per-key scopes and IP allowlists.
  • Timestamped requests to block replay attacks.
  • TLS 1.3 enforced on every endpoint.

Request Signing

  • HMAC-signed payloads verify request integrity.
  • Tamper detection on every client → server call.
  • Signature secrets never leave the server.

Rate Limiting

  • Per-key and per-IP limits with burst protection.
  • Automatic throttling and abuse detection.
  • Configurable rules per application.
