Xorble specialises in innovative software solutions for cloud based cryptography and Public Key Infrastructure (PKI).

In an era of increasing cyber threats, we aim to provide robust tools that enhance digital security, allowing organisations to protect sensitive data and ensure secure communications. 

The Xorble KSP for Azure Key Vault finally provides a safe and secure way to use certificates within Azure without exporting and copying private keys to every virtual machine that uses them. 

The following comparison table shows different Azure Key Vault options for handling keys. When the Xorble Key Storage Provider is used with Premium Key Vault it provides the most cost effective HSM based solution on the Azure platform.

NOTES

  • Key Vault Standard and Premium costs depend on operations and keys.
  • Xorble costs depend on VM size,
    • ~$175/month (PKI server, 4 CPU core 16GB of RAM)
  • Managed / Cloud / Dedicated HSM are always-on hourly services
    • (~$4.8/hour ≈ $3300/month)

Key Vault Premium + Xorble KSP provides the best balance of cost, security and Windows integration – The most cost-effective way to provide a FIPS-backed HSM service with true native Windows KSP integration for Azure VMs is Xorble KSP for Azure Key Vault.

Managed / Cloud / Dedicated HSM are justified where strict single-tenant isolation is required.
