Production hardening is a focused engineering sprint that fixes the highest-risk issues an audit identifies, before a launch, a handoff, or a fundraising round.
It's the fix to an audit's diagnosis. An audit tells you what's wrong and in what order it matters; a hardening sprint is the work that actually resolves it.
What typically gets hardened is whatever the audit's PRISM score flags first: commonly consolidating duplicated auth checks, adding missing failure paths, fixing secrets and deploy configuration, and cleaning up duplicated logic.
It's most useful for founders and agencies who got a concerning audit score and want the fixes handled by someone who already understands the codebase, rather than bringing in a new engineer from zero context.
Yes, hardening fixes what an audit finds. Skipping straight to hardening means guessing at priorities instead of fixing what's actually highest-risk first.
It depends on what the audit finds and how much needs fixing. Scoped individually after the audit, not sold as a fixed package upfront.
