CIS Controls v8.1 · CIS Control 15: Service Provider Management

15.3 Classify Service Providers

Classify service providers using one or more factors such as data sensitivity and volume, availability needs, applicable regulation, inherent risk and mitigated risk, and revisit classifications yearly or after significant change. Implementation Groups: IG2 and IG3 (not in the IG1 baseline; applies from IG2 upward). Asset type: Users. Security function: Govern.

Source: CIS Controls v8.1, 15.3. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open CIS Controls v8.1 in the compliance library.

Scope: Implementation Groups: IG2, IG3. Security function: Govern; asset type: Users.

Each safeguard shows its Implementation Groups. IG1 is the essential baseline for every enterprise, IG2 adds to it, IG3 is all 153. Version 8.1 adds the Govern security function and asks for more processes to be documented; numbering is unchanged from v8.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

First move

No system holds this evidence for you: it is people and documents. Reminders and routing to the owner still save time. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date.
