SOC 2 for the contract you're trying to close.
Your buyer won't sign without it.

Honest answer: a usable SOC 2 Type I report typically takes 4 to 6 months from a cold start — gap assessment, remediation, evidence collection, then 4 to 8 weeks of CPA audit fieldwork and report drafting. A SOC 2 Type II report requires an additional 3 to 12 month observation window after Type I, so the full Type II report is usually 9 to 15 months out from the day you start.

The practical move when a contract is blocked: tell your buyer you are "in SOC 2 readiness with a CPA engagement letter signed" and offer a written security overview, a recent penetration test report, your incident response plan, and a target Type I report date. Most buyers will conditionally proceed under that documentation if you can credibly commit to a Type I delivery date.

The deal stays moving while the audit runs in parallel.

Type I attests that your controls are designed appropriately at a specific point in time. Type II attests that those controls operated effectively over an observation window of three to twelve months.

Most enterprise customers ultimately require Type II — Type I alone is generally treated as a step toward Type II rather than a long-term destination.

The standard path is: complete Type I first (proves design, satisfies near-term review requests), then immediately enter the observation window for Type II, which closes 6 to 12 months later. Buyers who reject Type I outright usually accept a Type I report with a signed CPA engagement letter committing to Type II by a specified date.

The Security category — also called the Common Criteria — is mandatory for every SOC 2 engagement. The other four — Availability, Processing Integrity, Confidentiality, and Privacy — are scope decisions driven by customer commitments and the nature of the service.

A typical B2B SaaS handling customer PII selects Security plus Availability plus Confidentiality. A payments or financial processing platform adds Processing Integrity. A healthtech or company handling consumer personal data adds Privacy.

Choosing additional criteria carries audit cost and ongoing evidence-collection burden, so most organizations limit scope to what their customer contracts explicitly require. Over-scoping is one of the most common and most expensive mistakes in a first SOC 2.

SOC 2 audits can only be performed by licensed CPA firms registered with the AICPA, and only by firms with active SOC reporting practices. Most general-purpose CPA firms do not have SOC practices and cannot issue a SOC 2 report regardless of how long you've worked with them on tax or financial audit.

The CPA firm selection matters in another way: experienced buyers and their reviewers know which auditors are credible and which are not. Reports from boutique-but-respected SOC firms carry more weight than reports from firms with no recognizable security audit track record.

WatchUr6 does not perform the SOC 2 audit itself — that would be an independence conflict — but we coach our clients through CPA firm selection, scope negotiation, evidence package preparation, and walkthrough rehearsals so the audit fieldwork runs cleanly.

Significant overlap exists, but no two frameworks map one-to-one. HIPAA's Security Rule shares roughly 60–70% of its control surface with SOC 2's Security and Confidentiality criteria. ISO 27001's Annex A overlaps approximately 80% with SOC 2 Common Criteria. PCI DSS shares network segmentation, access control, and monitoring requirements with SOC 2 but operates at much higher prescriptive specificity for cardholder data environments.

The practical leverage: organizations with an existing ISO 27001 certification or a mature HIPAA program can often reach SOC 2 Type I in 3 to 4 months rather than 6, because the policies, procedures, and evidence trails already exist and only need to be re-organized against the SOC 2 trust services criteria.

We build a crosswalk document at engagement start so you can see exactly what reuses and what doesn't.

The observation window — typically 6 to 12 months — is the period during which the CPA auditor evaluates whether your controls operated effectively across a representative sample. Failures during the window do not automatically disqualify a Type II report, but they appear as exceptions in the final report and can damage its market value.

The most common failure modes: access reviews skipped or completed late, change management bypassed for emergency deployments, vendor reviews not completed annually, security training not delivered within the required cadence, incident response procedures executed inconsistently.

The work during the window is operational discipline more than technical engineering — controls must be performed on schedule, evidence must be captured at the time, and exceptions must be documented as they occur rather than reconstructed during fieldwork. This is where most first-time Type II programs struggle, and where we focus the sustainment engagement.
