OpenBao + DuoKey SD-HSM
Same Vault API. Zero application code changes. No per-token licensing.
The Cockpit
State, latency, remote key status and full lifecycle history for every vault you run, Securosys CloudHSM, software, or hybrid.


Add an MPC vault next to your HSMs: key shares split 2-of-3, with state, latency and lifecycle tracked like any other vault.
The problem
BSL 1.1 and per-client-token pricing turn secrets into a recurring tax.
Enterprises that grew on HashiCorp Vault now face unsustainable run-rate as every workload token becomes a billable client. The pressure is commercial and operational, not cryptographic.
The MPL cost model teams budgeted against is gone.
Every workload token shows up as a billable client.
Seal-wrap still assumes a hardware budget you may not want.
Leaving Vault usually means touching application code.
