Replace a single-key HSM with T-of-N distributed signing. No single party can sign alone; compromising T-1 parties does not compromise the key.

Run Herzberg share refresh on a schedule so that compromising the same T parties over time still does not reveal the key.

Operate a national or industry PKI where the root of trust is held by a quorum of institutional parties rather than a single operator.

Sign build artifacts at release time using threshold keys held outside CI. Compromising CI does not compromise the signing key.
