Service Encryption for Microsoft 365

Microsoft 365 Customer Key under your authority

Use Microsoft’s Customer Key path so Microsoft cannot unlock regulated content alone.

The problem

Customer Key still depends on hardware you do not operate

Traditional HSMs add cost and operational drag to M365 service encryption.

Organisations adopting Microsoft 365 Customer Key need independent key control, but hardware modules are slow to scale, hard to evidence and still concentrate unwrap authority in one place.

  • HSM lead time

    Racks, firmware and staff delay Customer Key programmes.

  • One unwrap device

    A single module remains a single point of compromise.

  • Who held the key

    Auditors ask who could unwrap production Customer Key material.

  • Key volume

    Workloads grow faster than hardware you can rack.
