SOC 2 Type I vs Type II: Cost & Timeline

SOC 2 Type I and SOC 2 Type II are security audit reports that evaluate a company’s internal controls using the AICPA Trust Services Criteria.

SOC 2 Type I assesses whether security controls are properly designed at a specific point in time.
SOC 2 Type II evaluates whether those controls operate effectively over a period of time, usually three to twelve months.

Most enterprise buyers expect a SOC 2 Type II report because it demonstrates that controls are consistently followed, not just documented.

In practice, many startups complete a SOC 2 Type I first to show early progress toward compliance, then move to a Type II once their controls have been operating long enough to support an observation period. Companies selling to large enterprises often go directly to Type II. AI startups often face accelerated timelines because enterprise buyers require assurance around model security and data governance — our SOC 2 for AI companies guide covers the specific considerations.

SOC 2 Type I vs Type II Summary

Key takeaway

A SOC 2 Type I confirms that your security controls are designed properly.
A SOC 2 Type II confirms that those controls actually operate effectively over time.

What SOC 2 Actually Measures

SOC 2 audits evaluate how a company protects customer data using the Trust Services Criteria, a framework created by the American Institute of Certified Public Accountants (AICPA).

The framework includes five criteria:

• Security
• Availability
• Confidentiality
• Processing Integrity
• Privacy

Security is required for every SOC 2 report. The other criteria are optional depending on the company’s services and risk profile. For a detailed breakdown of what auditors expect, see our SOC 2 requirements guide.

Auditors evaluate whether your organization has appropriate policies, systems, and processes in place to protect customer data based on these criteria.

Which SOC 2 Report Do Most Companies Need

In most situations, companies ultimately need a SOC 2 Type II report.

Enterprise customers, procurement teams, and security reviewers typically want proof that controls operate consistently over time. A Type II report provides that assurance because auditors test real activity across an observation period.

A SOC 2 Type I report can still be useful for early stage startups. It demonstrates that your controls are designed properly while you build the operating history required for a Type II.

Cost Differences Between Type I and Type II

SOC 2 audit costs vary based on company size, scope, and auditor, but the typical ranges are:

Several factors can increase audit costs:

• Including Trust Services Criteria beyond Security such as Availability or Privacy
• Operating in a regulated industry
• Having a complex infrastructure across multiple cloud providers
• Needing significant remediation work before the audit begins

Using a compliance platform such as Secureframe or Sprinto can reduce audit costs by automating evidence collection and reducing the amount of manual testing required.

Timeline Differences Between Type I and Type II

One of the biggest differences between SOC 2 Type I and Type II is the timeline required to complete the audit.

A Type I can be completed relatively quickly because auditors only evaluate the design of controls on a specific date.

A Type II requires an observation period during which auditors confirm that the controls operate consistently. This additional testing period makes the audit longer but also more credible.

For a detailed explanation of the process, see our SOC 2 audit timeline guide.

What a SOC 2 Type I Report Evaluates

A SOC 2 Type I report evaluates whether your security controls are properly designed at a specific point in time.

Auditors review documentation, systems, and policies to determine whether your organization has implemented controls that meet the Trust Services Criteria.

Typical areas reviewed include:

• Documented security policies and procedures
• Access control systems and permissions
• Encryption and infrastructure security configuration
• Monitoring and logging systems
• Risk assessment processes

The auditor does not test whether the controls operated consistently over time. Instead, the report reflects the state of the environment on the audit date.

Because of this limited scope, a Type I report can often be completed quickly. Startups sometimes pursue a Type I when they need to demonstrate progress toward compliance while preparing for a longer Type II audit.

Companies often use this phase to finalize policies and identify gaps before starting a full observation period. Our SOC 2 readiness checklist explains the preparation steps in more detail.

What a SOC 2 Type II Report Evaluates

A SOC 2 Type II report evaluates both the design of controls and their operating effectiveness over a defined observation period.

Instead of reviewing a single snapshot, auditors examine evidence from real activity across the observation window.

Examples of what auditors typically review include:

• Access reviews performed on schedule
• Security alerts investigated within defined response times
• Employee background checks completed before granting access
• Change management approvals for production deployments

Auditors review samples of real activity from across the observation period to confirm that procedures were followed consistently.

Because it demonstrates ongoing control operation, a Type II report carries significantly more weight with enterprise buyers, regulated industries, and security teams.

When Startups Choose Type I First

Many startups pursue a SOC 2 Type I before beginning a Type II audit.

Common reasons include:

Speed to close a deal

If a prospect requires a SOC 2 report and the company has none, a Type I can often be completed in one to three months.

Limited operating history

If the company recently launched its product or security program, there may not be enough historical evidence to support a Type II observation period.

Budget constraints

Type I audits are usually 30 to 50 percent less expensive than Type II audits.

Internal readiness

Some teams use a Type I audit as a structured preparation step before beginning a longer Type II engagement.

The trade-off is that many enterprise buyers treat a Type I report as temporary and expect a Type II within the next audit cycle.

If you are using a compliance automation platform such as Drata or Vanta, your auditor can often structure the engagement so the Type I transitions smoothly into a Type II.

---

When Companies Go Straight to Type II

Some companies skip Type I and begin directly with a SOC 2 Type II audit.

This approach often makes sense when:

• Security controls have already been operating for several months
• The sales pipeline includes enterprise buyers that require Type II
• A compliance automation platform is already collecting evidence
• The company’s auditor recommends starting with a full observation period

Going directly to Type II can also reduce long term costs because you avoid paying for two separate audit engagements.

If your controls are mature enough and your timeline allows for the observation period, starting with Type II is often the more efficient path.

---

How the Observation Period Works

The observation period is unique to SOC 2 Type II audits and is often misunderstood.

What it is

A defined period of time during which your security controls must operate effectively.

How long it lasts

The minimum is usually three months. Many auditors and enterprise customers prefer six months. Some regulated industries expect a full twelve month period.

When it starts

The observation period begins once your controls are fully implemented and the auditor agrees the environment is ready.

What happens during the period

Your team operates normally while following documented procedures for security reviews, change management, incident response, and access control. Evidence from these activities is collected continuously.

What happens if controls fail

A small number of exceptions is common and usually manageable. Repeated or serious failures can result in qualified opinions or other findings in the final report.

After the observation period

Once the observation window closes, the auditor performs final testing and prepares the report. This stage typically takes two to six weeks.

SOC 2 Type I vs Type II FAQ

What is the biggest difference between SOC 2 Type I and Type II?

The main difference is what the auditor evaluates. SOC 2 Type I tests whether security controls are properly designed at a specific date. SOC 2 Type II tests whether those controls operate effectively over a defined period of time.

Can a company skip SOC 2 Type I?

Yes. Many companies go directly to SOC 2 Type II if their controls have already been operating long enough to support an observation period.

Can I start with a Type I and upgrade to a Type II?

Yes. Many startups complete a Type I first and begin the Type II observation period immediately afterward. Some auditors offer bundled pricing for this approach.

Do enterprise customers accept Type I reports?

Some organizations accept a Type I during early vendor evaluation, but most enterprise buyers ultimately require a Type II report.

How long is a SOC 2 Type II report valid?

SOC 2 reports are generally considered current for about 12 months. Most companies perform a new audit each year to maintain an up-to-date report.

Can I choose which Trust Services Criteria to include?

Yes. Security is mandatory for all SOC 2 reports. Availability, Confidentiality, Processing Integrity, and Privacy are optional depending on the company’s services.

Is a Type II harder to pass than a Type I?

Type II audits are more rigorous because auditors test whether controls operate consistently over time. Type I audits evaluate only control design at a single point in time.
