Corporate Investigation Mistakes Undermine SOC 2 Evidence and Regulatory Audits
What Happened — In a Help Net Security video, BlackBerry’s VP and Chief Security Advisor Christine Gadsby outlines four common errors organizations make during the early stages of a corporate investigation: treating the event as a purely technical issue, losing track of sensitive conversations, assuming knowledge of who receives information, and limiting the chain of custody to devices and logs while ignoring interviews and executive communications.
Why It Matters for Compliance & Audit Readiness
- The first hours set the foundation for the SOC 2 Incident‑Response (CC6.1‑CC6.3) and Communication (CC7.1‑CC7.2) controls; missteps can break the audit trail and invalidate evidence.
- Incomplete chain‑of‑custody documentation can trigger regulator scrutiny, as seen in the > $2 B in SEC penalties since 2021.
- Mapping these investigation practices to a continuous‑compliance framework ensures you have defensible evidence for future SOC 2 audits.
Who Is Affected — Financial services firms (the sector with the most SEC penalties), large enterprises in technology, healthcare, and any organization subject to SOC 2 or other regulatory audits.
Recommended Actions
- Designate an incident commander before any evidence is collected.
- Choose communication channels that generate immutable logs (e.g., secure email with DLP, approved collaboration tools).
- Maintain a living register of all participants, interviews, and executive briefings.
- Extend the chain of custody beyond devices to include interview notes, meeting recordings, and decision logs.
- Align these steps with your SOC 2 control map and capture evidence in a centralized repository.
