CC2.2

Communicates with External Parties

SOC 2 · 2017 TSC (2022 Revised Points of Focus) · Last verified August 2026

Objective

Communicate relevant information with customers, regulators, vendors, and other external parties, and provide channels for receiving information from them.

Points of focus

  • Provide external parties accurate information about commitments and controls
  • Maintain channels for reports, complaints, and security concerns
  • Route external information to responsible internal owners

Implementation notes

Maintain owned channels for security reports, privacy requests, status incidents, and vendor notices; define response clocks and ensure customer-facing claims are reviewed against actual production controls. Operationalize provide external parties accurate information about commitments and controls in ticketing, IdP, or GRC workflows with named owners — not only in a static policy PDF. Retain trust center, status page, and customer security communications with reviewer identity, population scope, dates, and remediation outcomes auditors can sample. A recurring failure mode is that the status page omits a material outage affecting contractual commitments Revisit after material architecture, vendor, data-flow, or leadership changes and document the decision.

Audit tip: Sample trust center, status page, and customer security communications with dates and named reviewers. Be ready to walk through how you detect and correct: the status page omits a material outage affecting contractual commitments

Evidence auditors typically request:

  • Trust center, status page, and customer security communications
  • Published vulnerability-reporting channel and triage records
  • Vendor notices and customer complaint escalation logs

Common gaps

  • The status page omits a material outage affecting contractual commitments
  • Security reports sent to a public mailbox are not assigned or tracked

Frequently Asked Questions

Communicates with External Parties applies to the systems and commitments in your Trust Services Criteria scope. Translate the requirement into concrete operating workflows — provide external parties accurate information about commitments and controls — with evidence stored where auditors and customers can sample it.

Lead with trust center, status page, and customer security communications and pair it with published vulnerability-reporting channel and triage records. Samples should show who performed the control, when, against which population, and what changed as a result.

Teams often fail because the status page omits a material outage affecting contractual commitments Close the loop with dated operating records and test the control on a realistic production path.

Control operation can often be shared across SOC 2, ISO 27001, GDPR, and HIPAA — but each framework uses different vocabulary and accountability. Maintain an explicit crosswalk rather than assuming equivalence.

Review at least annually and after material product, vendor, or data-flow changes. High-risk or privileged paths may need quarterly sampling even when the criterion does not prescribe a cadence.
