What are the steps?
Client Security Posture Handoff (Handoff)
- 01
Freeze the security scope in writing before the final delivery call
List every asset the agency touched (repos, ad accounts, CRM records, model endpoints) and mark each as in-scope or explicitly out-of-scope. Ambiguity here is where liability disputes start.
- 02
Transfer credentials through a vault, never through email or chat
Rotate every key the agency held, then hand over the new set via a shared vault with an expiry date. A documented case of a vibe-coded app with exposed keys produced a $4,000 OpenAI bill charged to the client, which is the cheapest version of this failure.
- 03
Deliver a findings register with severity, owner, and due date per item
A scanner such as Sentrint produces a weighted grade and severity-sorted findings; convert that output into a client-owned action list rather than a PDF that gets filed and forgotten.
- 04
Walk the client through the residual risk statement line by line
State plainly which threats remain unmitigated and why. No agency can promise absolute security against evolving attack surfaces, and saying so on the record protects the retainer relationship.
- 05
Confirm the client's incident contact and escalation window
Name the person who answers at 2am, the channel they monitor, and the maximum time the agency will stay on a bridge call post-handoff. Put the number in the document, not in someone's memory.
- 06
Schedule the 30-day post-handoff verification check
Book it before the kickoff call ends. The check confirms credential rotation actually happened and that the client's team closed the high-severity items, or surfaces that they did not while the agency still has context.
- 07
Archive the handoff record against the account for the next engagement
Store the scope document, findings register, and verification notes where the delivery team can retrieve them. The next security scoping call starts from this file, not from zero.
