What happens if I miss evidence during my SOC 2 observation period?
What Happens When Evidence Is Missing
When an auditor can't find evidence for a control during the observation period, they record an exception. An exception means the control didn't operate as described in your policy for that instance.
Exception Severity
| Situation | Impact |
|---|---|
| Missed one quarterly access review | Minor exception — unlikely to affect opinion |
| Skipped access review for the entire period | Major exception — affects opinion |
| One hotfix without documentation | Minor exception — normal for startups |
| Multiple undocumented direct pushes to main | Pattern of control failure |
| Missing incident response for a known incident | Serious — control design questioned |
| No evidence for an entire control area | May result in qualified opinion |
Will It Cause a Qualified Opinion?
One or two isolated exceptions typically don't cause a qualified opinion. Auditors use professional judgment: Was this an isolated oversight or a systemic failure?
Isolated exception: "We missed the Q2 access review because the CTO was on leave, but Q1, Q3, and Q4 reviews were completed."
Systemic failure: "We wrote a policy saying quarterly access reviews but never conducted any."
How to Prevent Missing Evidence
- Calendar reminders: Set quarterly reminders for access reviews, vendor reviews, and policy updates
- Evidence checklist: Maintain a list of recurring evidence tasks with due dates
- Early collection: Start collecting evidence from day one of the observation period
- Automation: Use tools that continuously collect evidence rather than relying on manual snapshots
What to Do If You Already Missed Something
- Don't fabricate evidence. Backdating screenshots or creating fake review documents is worse than the original gap.
- Document the gap. Write down what was missed, why, and what you've done to prevent it from happening again.
- Discuss with your auditor. They may have suggestions for compensating evidence or alternative procedures.
- Fix the process. Implement the calendar reminders and checklists so it doesn't happen again.
