A customer security review, an insurance renewal and a formal certification project can ask similar questions while expecting different evidence. We begin with the request, the systems it concerns and the date by which your business needs to respond. That gives the technical work a defined purpose.
For a smaller office, the first phase may be finding out who controls the email accounts, which computers are maintained and whether important information can be recovered.
A more extensive request may also need application providers, internal managers or a qualified compliance adviser involved. We identify those dependencies before describing the review as complete.
If the request covers only one business unit or application, we keep that scope visible. Findings from a limited review should not be presented as assurance about every system in the company. The resulting plan explains what was examined, what remains unknown and which decisions need someone else's input.
