Not Only Matter-Compliant, but Ready for Matter 1.5

  • DAC covers cameras and closures, supporting secure attestation across video streaming and OTA updates.

  • PKI / CLM centralize certificate operations for device fleets, with clear paths into EV charging and home storage.

  • KMS with HSM strengthens governance for keys and signing as deployments scale.

Not Just HSM Deployment, but a Key and Signing Hub

  • Keys are generated, stored, and used inside the HSM, keeping private keys off application servers.

  • KMS manages the key lifecycle and orchestrates Code Signing workflows for firmware releases.

  • Compatible with multiple HSM vendors, letting you reuse existing modules while leaving room for future expansion.
