What SOC 2 P4.3 requires

Secure disposal of personal information is one of 18 criteria in the Privacy (P) series of the Privacy category. Personal information is securely disposed of to meet the entity's privacy objectives. Because this sits outside the Common Criteria, it is only tested when Privacy is in the scope of your engagement — check your report scope before building evidence for it.

Audit evidence assessors look for

When preparing for a SOC 2 audit against P4.3, gather artefacts such as:

  • PI disposal procedures
  • Deletion execution logs across systems and backups
  • Certificates of destruction
  • Verification that disposal covers third-party copies

ISO 27001 mapping

P4.3 corresponds to the following ISO 27001:2022 Annex A control(s): A.8.10. If you already run an ISO 27001 ISMS, map your existing evidence for these controls to P4.3 rather than duplicating work.

Frequently asked questions

Is P4.3 required for a SOC 2 report?

Only if the Privacy category is in scope. The Common Criteria (CC1–CC9) are mandatory for every SOC 2, but P criteria are tested only when you elect to include Privacy in the engagement. Scope is your choice, usually driven by customer contracts.

How does an auditor test P4.3?

In a Type 1 report the auditor assesses design only — does a control exist at a point in time that would meet P4.3 if it operated. In a Type 2 report they also test operating effectiveness by sampling evidence from across the review period, typically 3 to 12 months. That difference is why Type 2 evidence has to be continuous rather than assembled the week before fieldwork.

What happens if P4.3 fails testing?

A control that fails becomes an exception, which the auditor describes in the report along with management's response. Exceptions do not automatically make a report "failed" — a SOC 2 report is an opinion, not a pass/fail certificate — but a qualified opinion is what customers notice, so remediate and re-test before fieldwork closes where you can.

Does SOC 2 P4.3 map to ISO 27001?

Yes — P4.3 aligns with ISO 27001:2022 Annex A control(s) A.8.10. If you already run a certified ISMS, re-point that evidence rather than building a parallel set; the underlying control is the same and only the reporting format differs.
