Access sprawl is still one of the most common inherited problems
Too many client environments still rely on long-lived keys, manual account handling, uneven offboarding, and undocumented access paths. That works until turnover, audit pressure, or a security incident exposes how weak the access model really is.
SSH certificates give operators a cleaner way to control identity, validity windows, and access issuance without managing a mess of permanent keys on every system.
This is exactly the sort of modernization clients will pay for
Most clients will never ask for SSH certificates by name. They will ask for cleaner onboarding, safer privileged access, simpler offboarding, and an environment that passes review without a scramble. MSPs should translate the technical mechanism into those business outcomes.
This is also a strong wedge service. Once you are trusted to modernize access, you are already in position to improve broader identity, endpoint, and infrastructure discipline.
