SOC 2 for startups: when you need it and how to approach it
By Kike Gandia · Co-Founder & CEO, OSCP
SOC 2 is, by far, the security requirement most likely to stall an enterprise deal for a SaaS startup. It isn't a law or a regulatory obligation: it's an audit standard that your large clients demand as proof you handle their data responsibly. This guide explains when to start, which report type you'll be asked for, and what to expect from the actual process.
Type I vs Type II: the difference that decides the timeline
A SOC 2 Type I report assesses whether your controls are well-designed at a single point in time: it can be achieved in weeks. A Type II assesses whether those controls operated effectively over an observation period, typically 3 to 12 months. Most mature enterprise clients end up asking for Type II, but Type I is a valid starting point while you build the track record needed for Type II.
When your startup genuinely needs it
The clearest signal is when a prospect or enterprise client includes SOC 2 as a requirement in their vendor security questionnaire, or demands it outright as a contract clause. Chasing the certification before that real demand exists is usually a premature expense; very early-stage startups (pre-Series A) rarely need it yet.
What the process actually involves
Selecting the applicable Trust Services Criteria (security is mandatory; availability, confidentiality, processing integrity and privacy are optional depending on your product), implementing controls (access management, monitoring, change management, incident response), the observation period for Type II, and an audit by a licensed CPA qualified to issue SOC 2 reports.
Realistic cost and timeline
For a small startup on a standard cloud stack, a Type I is usually achievable in 2-3 months, with consulting plus audit costs between €15,000 and €40,000. A Type II adds the observation period (3-12 months) before the report can be issued. Compliance automation platforms can reduce preparation time, but they don't eliminate the observation period the standard requires.
Type I and Type II side by side
Laid out in a table, the choice stops being a technical question and becomes a commercial calendar decision:
| Type I | Type II | |
|---|---|---|
| What it assesses | Control design at a single point in time | That controls actually operated over a period |
| Time window | One day | Typically 3 to 12 months |
| Evidence the auditor asks for | Configurations, policies and permissions as they stood that day | Samples spread across the period: real joiners and leavers, change tickets, access reviews |
| Commercial use | Unblocking a client who needs to see movement; buying time | Closing mature enterprise deals; the standard answer in questionnaires |
| Main risk | The client replying "this is not enough, I need Type II" | A control failing mid-period and surfacing as an exception |
The operational consequence of Type II is the one that surprises teams most: during the observation period the controls have to be genuinely executed and leave a trace. If the quarterly access review is documented but nobody ran it in Q2, that cannot be fixed afterwards — it appears as an exception in the report.
What to show while you do not have the report yet
Months pass between a client asking and the report existing, and the contract does not wait. What tends to work, in order of credibility: a letter of engagement naming the observation period start date and signed by the audit firm you have hired; a recent pentest report with critical findings already remediated; and documentation of the controls already operating (access management, change management, incident response). One detail worth knowing in advance: once you do have a Type II, a gap opens between the end date of the period covered and the moment a client asks for it. That gap is covered by a bridge letter, issued by your own management — not the auditor — stating that there have been no material changes to the controls since the report closed. It is standard practice and most buyers accept it, but it only covers a few months: it does not replace the next report.
FAQ
Is SOC 2 legally required?
No. It's a voluntary audit standard (AICPA) that your clients require contractually, not a regulatory obligation like GDPR or NIS2.
Can I show a pentest instead of SOC 2?
A recent pentest often helps and sometimes suffices for less demanding clients, but most mature enterprise buyers specifically ask for the SOC 2 report, not a substitute.
What happens if I fail the surveillance audit?
SOC 2 isn't a permanent certification: each report covers a specific period. You need to repeat the audit cycle periodically (usually every 12 months) to keep reports current.
Our cloud provider already has SOC 2. Does that cover us?
It doesn't vouch for you, but it is one piece of the process. Your provider's SOC 2 report covers their infrastructure, not your application or how you manage access, and your auditor will ask for evidence that you review that report as part of vendor management — including reading the complementary user entity controls section, where the provider lists what it expects you to do. Ignoring that section is one of the most common sources of exceptions in a first Type II.
Can we show the SOC 2 report to anyone?
No. A SOC 2 report is restricted-use: it is shared with clients, prospects and their auditors under a confidentiality agreement, not published on your website. What you can publish is the fact that you hold the report and will make it available under NDA. It pays to have that flow ready (who sends it, under which NDA) before the first prospect asks, because in practice they ask mid-negotiation.
What will we have to give the auditor during the period?
Read access to or screenshots of your identity systems, code repository, ticketing tool and cloud console, plus the HR records needed to test joiners, leavers and training. The auditor does not need admin access or access to your customers' data; they work from samples. The real burden is not access, it is collection: if evidence is not captured as the period goes along, reconstructing it at the end is where the cost blows up.
What if the report comes back with exceptions?
A report with exceptions is still a valid report and can be shared; it is not a fail. The auditor describes the exception and management adds a response explaining what was fixed. Most buyers accept it when the exception is contained and remediation is documented. What does raise flags is a qualified opinion on a core control such as access management.
