SOC 2 Control Implementation Guide

Service Commitments

Service Description Accuracy for SOC 2

Service descriptions, RFP responses, and assurance materials accurately describe implemented capabilities, limitations, dependencies, and customer obligations.

Use this guide to put the control into operation, decide what records to retain, and check that an auditor can trace the evidence back to the work your team performed.

What this control should accomplish

Customer-facing descriptions match the service that is actually operating, including its security capabilities, limitations, dependencies, and customer obligations.

First SOC 2 program

A credible starting point

Keep an approved set of service facts covering architecture, security, availability, support, data handling, and known limitations. Require a technical and security owner to review material external claims before they are published or sent to a customer.

As the company scales

Make it repeatable

Establish an authoritative service-content library, assign subject owners by claim type, and trigger coordinated review when product releases, architecture changes, incidents, provider changes, or new commitments could make published information inaccurate.

How to implement Service Description Accuracy

  1. 1

    Inventory external descriptions

    Identify trust-center content, service descriptions, sales assurance material, security questionnaire responses, product documentation, and other statements customers rely on.

    You should end up with: A content inventory with owner, audience, location, current version, and last review date.

  2. 2

    Establish authoritative facts

    Document approved facts for important claims such as encryption, access controls, backups, monitoring, support, data location, and external dependencies.

    You should end up with: A controlled fact set linked to the systems or processes that support each statement.

  3. 3

    Validate claims with operators

    Have the people who run the service confirm that claims describe current capability and preserve qualifications, exclusions, product differences, and customer responsibilities.

    You should end up with: Dated subject-owner review with corrections and resolved questions.

  4. 4

    Approve before external use

    Route material new or changed statements through service, security, legal, and other relevant reviewers, then lock the approved version for publication.

    You should end up with: An approval trail connected to the exact content version used externally.

  5. 5

    Trigger review from change

    Connect release, architecture, incident, vendor, and contractual-change processes to a content impact check so affected descriptions are updated promptly.

    You should end up with: Change records showing which content was reviewed and what was updated or confirmed unchanged.

  6. 6

    Test consistency periodically

    Sample important claims across customer-facing channels and compare them with each other and with the current operating environment.

    You should end up with: A periodic accuracy review with discrepancies, owners, due dates, and completed corrections.

Evidence to keep, and what it should prove

Build the evidence set in three layers: what defines the control, who approved or reviewed it, and what proves it operated. Collect operating records when the work happens so they remain dated, attributable, correctly scoped, and traceable to the underlying activity.

Before sharing, remove unrelated personal or customer data, never expose passwords, tokens, or secret values, preserve enough source context to authenticate the record, and use the secure exchange approved for the engagement.

Policy / design artifacts

Documents that define the control, its scope, ownership, and expected way of working.

Trust-center content

  • Confirm what the record proves

    Published assurance claims about security, privacy, availability, and compliance reflect approved current facts and disclose relevant scope or limitations.

Weak evidence to avoid

A trust-center page claiming all data is encrypted everywhere with no service scope, qualification, technical owner, approval date, or supporting configuration reference.

Approval / review evidence

Records showing that an accountable person reviewed, approved, challenged, or accepted the work.

security questionnaires

  • Confirm what the record proves

    reviewer decisions

A ticket approved before the final edits with no record that reviewers saw the version later published to customers.

Operating / technical evidence

Dated proof that the control actually ran, such as tickets, logs, settings, exports, reports, and test results.

change history

  • Confirm what the record proves

    Material changes to service claims are traceable to the triggering product or operating change, review, approval, and publication event.

  • Include this context

    content identifier

  • Include this context

    prior and new version

  • Include this context

    triggering change

  • Include this context

    change summary

    effective date

Weak evidence to avoid

A live webpage with a recent updated date but no prior version, change summary, triggering release, or person who approved the revision.

Which records should you prepare for the audit?

Type 1

Evidence at the as-of date

Current approved trust-center content, security answer source material, service description, content-review procedure, and the latest completed approval and change history as of the examination date.

Type 2

Evidence across the review period

All trust-center, service-description, security-questionnaire, and assurance-content items newly published, delivered, or materially changed during the review period, plus all periodic accuracy reviews due in the period.

Completeness check

Reconcile externally available trust and service content plus delivered questionnaire records to approval history, then reconcile material product and architecture changes to recorded content-impact decisions.

How an auditor may test this control

Use this checklist to prepare for procedures an auditor may perform. The exact steps and sample selection depend on your engagement scope and the service auditor's professional judgment.

  • Confirm the intended control outcome

    Determine whether the control is designed to achieve this result: Customer-facing descriptions match the service that is actually operating, including its security capabilities, limitations, dependencies, and customer obligations.

  • Confirm ownership and operating cadence

    Compare the documented owner with the intended role (Service Owner / Legal / CISO), then compare dated records with the stated cadence: Ongoing; review at least annually.

  • Establish the complete audit record set

    Reconcile externally available trust and service content plus delivered questionnaire records to approval history, then reconcile material product and architecture changes to recorded content-impact decisions.

  • Prepare the as-of-date evidence for a Type 1 engagement

    Current approved trust-center content, security answer source material, service description, content-review procedure, and the latest completed approval and change history as of the examination date.

  • Prepare period evidence for a Type 2 engagement

    All trust-center, service-description, security-questionnaire, and assurance-content items newly published, delivered, or materially changed during the review period, plus all periodic accuracy reviews due in the period.

  • Inspect the policy / design artifacts

Common implementation and evidence gaps

  • Different sales, legal, trust-center, and product channels describe the same capability differently.
  • Absolute words such as always or never are used where the system has conditions, exclusions, or phased coverage.
  • Roadmap capabilities are described as current before the underlying operational work is complete.
  • A reviewer approves wording without checking the system configuration or process that supports the claim.
  • Product and provider changes do not trigger review of existing customer-facing descriptions.

Before you call this control ready

  • Can every material service claim be traced to an accountable subject owner and supporting operation?
  • Do customer-facing channels agree on security capabilities, limitations, and responsibility boundaries?
  • Does the approval record identify the exact version that was published or delivered?
  • Do material releases and architecture changes include a service-description impact decision?
  • Can the company show that discovered inaccuracies were corrected across all affected channels?
