What each report tells a buyer
A Type 1 report describes whether your controls are suitably designed, as of a specific date. It answers: "Do you have the right controls in place today?"
A Type 2 report covers the same design question and adds operating effectiveness across an observation period, commonly three to twelve months. It answers: "Did those controls actually work, consistently, over time?" Many enterprise buyers ask for Type 2 for that reason.
The Trust Services Criteria
SOC 2 is organized around the AICPA Trust Services Criteria. The Security category is required and forms the common criteria (the "CC" controls) that every report includes. The other categories are optional and should be chosen based on what your customers need:
- Availability: uptime commitments, capacity planning, backup and recovery
- Processing integrity: complete, valid, and accurate processing of customer data
- Confidentiality: how confidential information is identified, protected, and disposed of
- Privacy: personal information handling across its lifecycle
Adding categories increases the number of controls and the testing burden. Add them because a customer needs them, not because they sound thorough.
What auditors actually test
For a Type 2 report, the CPA firm samples evidence across the observation period. The samples are where most companies struggle. Typical test areas include:
- Access provisioning and deprovisioning, with timely offboarding evidence
- Quarterly or periodic access reviews, signed off by an owner
- Change management tickets with approvals and testing records
- Vulnerability scanning and remediation tracking
- Vendor risk reviews for critical suppliers
- Incident response tests and lessons-learned records
A practical path
If a customer needs a report this quarter, a Type 1 can serve as a credible milestone, and it gives you a design review before the observation period starts. Do not assume a buyer will accept it in place of a Type 2. Confirm that in writing first. Once the controls are stable, run the Type 2 observation period and keep evidence as you go. Retroactively assembling evidence for a sample is slower and riskier than collecting it in the normal course of work.
Mistakes that extend the timeline
- Scoping too narrowly, then discovering a buyer expects a production system that was left out
- Writing policies nobody follows, which auditors detect quickly in sampling
- Reviews that happen but are not documented with dates and sign-offs
- Offboarding delays that show up as exceptions in the sample
Start the Type 2 observation period as soon as your controls are operating reliably. The observation period cannot be shortened after the fact, so every week of delay pushes the report date back.
Frequently asked questions
What is the difference between SOC 2 Type 1 and Type 2?
A Type 1 reports on control design at a point in time. A Type 2 reports on control design and whether the controls operated effectively over an observation period, usually three to twelve months.
How long does a SOC 2 Type 2 take?
The observation period is typically three to twelve months, plus time for readiness work beforehand and the auditor's testing and report.
Do I have to include all five Trust Services Criteria?
No. Security is required. Availability, processing integrity, confidentiality, and privacy are optional and should be added based on customer requirements.
Is a SOC 2 report valid for a year?
Buyers generally treat a SOC 2 report as current for about twelve months after the period it covers. Some ask for a bridge letter if the report is older.
