what a certificate does and does not show

Read this before a customer asks you for one.

A certificate shows that an auditor looked at your system and what they found at that time. It does not show that you comply with a law.
who asks for it

service companies whose customers ask for it in sales questionnaires

what it asks of you

a licensed auditor's report on your controls

what it asks, and ways to meet it

The rule says what must be true in the company. It names no tools or methods: you choose them, and the people implementing it and the board answer for the choice. Under each requirement are the controls that usually deliver it. That grouping is our reading of the rule, not a list from the act.
