SOC 3
SOC 3 is a general-use, public summary of a SOC 2 engagement over the Trust Services Criteria. It delivers a high-level assurance statement without detailed controls/testing, making it suitable for websites and marketing. It’s typically issued alongside or after SOC 2 Type II.
What is SOC 3’s target audience & industries?
Prospects, customers, and partners who need a public attestation summary; common for SaaS and cloud services.
Does it apply to my organization?
You likely need a SOC 3 audit if you:
You sell SaaS/managed services/cloud and want an easy-to-share proof of security controls without exposing detailed test procedures (that’s SOC 2).
You already completed (or plan to complete) a SOC 2—ideally Type II. SOC 3 is typically issued from the same scope/period.
Your marketing, partnerships, or procurement teams want a trust signal that accelerates early-stage conversations.
What are the benefits of conducting a SOC 3 Audit?
Shareable public report (no NDA)
Reinforces trust early in the sales cycle
Complements SOC 2 by reducing disclosure risk
What are the core SOC 3 requirements?
Underlying SOC 2 basis: Completed SOC 2 (typically Type II) over defined TSC and scope.
Auditor’s public opinion: High-level assertion of controls suitability/effectiveness without detailed tests/results.
Consistent scope/period: SOC 3 must align to the same systems, TSC, and audit period as SOC 2.
Public release readiness: Sanitized system overview suitable for general use; versioning and date clarity.
Annual refresh: Reissue after each SOC 2 cycle; retire outdated reports.
What are the general guidelines for executing a SOC 3 report ?
Complete SOC 2 Type II for the same scope/period as the basis.
Request SOC 3 from your auditor, ensuring TSC scope matches the SOC 2.
Review language: Confirm the public summary contains no sensitive details.
Publish responsibly: Host latest SOC 3 on your site; version and date clearly.
Align marketing: Use accurate badges/claims; link to SOC 3 and provide a path to request SOC 2 under NDA.
Renew cadence: Update after each SOC 2 cycle; remove expired reports.
What are estimated timelines to complete a SOC 3 audit?
Startup: 1–2 weeks once SOC 2 Type II is done
Small to Large Companies: Incremental to SOC 2 (usually Type II): 2–4 weeks to produce the public report
What are the typical costs?
Costs vary by size, scope, and readiness by organizations: (T1 / T2)
Startups: 1 - 25 employees, single product, 1 prod environment, 1 region, few to no vendors - (incremental): $2k–$8k
All other companies: Incremental: $5k–$15k once SOC 2 is complete.
SOC 3 is a general-use summary; most work happens in the SOC 2.
(Ranges include typical readiness + audit/assessment (and operating period where applicable). Costs are USD and combine internal enablement/consulting + external auditor/assessor/cert body where relevant).
