SOC 2 for startups: what it is and how to get ready

SOC 2 for startups usually starts with one email: a larger customer sends a security questionnaire and asks for your SOC 2 report. A SOC 2 report is an independent CPA firm's opinion on how well your controls protect the system your customers rely on. It is not a certificate you buy, and it is not something a tool can produce for you. It is evidence that your team does what its policies say.

This guide explains what SOC 2 is, how a Type 1 report differs from a Type 2, when a startup really needs one, how to choose the scope, which engineering controls carry most of the work and how to pick an auditor. If the controls themselves are the gap, our DevOps implementation services are where we help.

What SOC 2 is, and what it is not

SOC stands for System and Organization Controls, a suite of reports defined by the American Institute of Certified Public Accountants (AICPA). The AICPA's SOC suite page describes them as reports CPAs provide so that customers can assess the risks of outsourcing a service. In a SOC 2 examination, the auditor reviews your description of your system and the controls you run against the AICPA's Trust Services Criteria.

Those criteria cover five areas: security, availability, processing integrity, confidentiality and privacy. As Microsoft's SOC 2 documentation sets out, the examination is performed under the AICPA's attestation standards, its SOC 2 guide and the 2017 Trust Services Criteria. The result is an attestation report with the auditor's opinion, not a pass mark or a certificate.

A SOC 2 report is detailed, so its use is generally restricted to customers and partners who need it. Large providers share theirs through a customer portal behind a sign-in. The AICPA's SOC 3 page explains the public option: a SOC 3 report addresses the same areas with less detail, so it is a general use report that can be freely distributed.

SOC 2 Type 1 vs Type 2

The two report types answer different questions. Google Cloud's SOC 2 page puts it simply: a Type 1 report covers the design of your controls at a specific point in time, while a Type 2 report covers their design and operating effectiveness over a period. Microsoft adds that Type 1 audits do not look back over a period of performance. In short, a Type 1 report checks the design at one date, and a Type 2 report checks design and operation over time. The drawing on this page places the documents a buyer may see by the time they cover and the independent assurance they carry: your own security questionnaire answers, a bridge letter, a Type 1 report and a Type 2 report. The table shows what the two reports mean for a buyer.

A Type 1 report can be a useful first step, because it can be issued once the controls exist. It is optional, though. If your buyers will only accept a Type 2, the time spent on a Type 1 may be better spent running the controls well from the start of the observation period.

When SOC 2 for startups makes sense

No law makes a startup get a SOC 2 report. The trigger is commercial: a customer, usually a larger company, wants independent evidence before it trusts you with its data. The clearest signals are a deal that stalls in security review, a procurement form that asks for your latest report, or the same long questionnaire arriving from several prospects.

It can wait when your customers are small businesses or consumers, when no one in your pipeline has asked, or when your product does not store or process customer data. In that case, put the effort into the controls themselves. Good access control, backups and change history help you whether or not an auditor ever looks.

Buyers who ask for SOC 2 often ask about security testing too. Our guide to penetration testing for startups covers when a test makes sense and how to prepare for one.

Choosing your scope and criteria

Scope decides how much work SOC 2 for startups turns into. You describe the system the report covers, which is normally your product, the infrastructure it runs on and the people and processes that operate it. A tight scope that matches what customers buy keeps the evidence manageable. We usually suggest starting with security first, and adding another category only when a customer contract promises it, such as uptime commitments for availability.

Your cloud provider is part of the picture, but it does not carry your controls. AWS's shared responsibility model separates security of the cloud, which AWS runs, from security in the cloud, which is yours: your data, your encryption choices, your operating systems and who has access. Some controls, such as physical security of the data centres, you inherit from the provider.

Read your provider's own SOC 2 report as well. Microsoft notes that its reports end with user entity responsibilities, the controls customers must run themselves if the system as a whole is to meet the criteria. Your auditor will expect you to have covered them.

The engineering controls that carry most of the work

Policies matter, but most of the evidence in a young company comes from how engineering runs day to day. These are the controls a small team usually owns, and the ones worth getting right before the observation period starts.

• Access control. Least-privilege access to production, single sign-on with multi-factor authentication, and access removed on the day someone leaves. Access reviews on a set schedule, with a record of each one.
• Change management. Every production change goes through a pull request, a review and an automated pipeline, so the change history shows who changed what and who approved it.
• Logging and monitoring. Logs from your app and infrastructure kept in one place, with alerts that reach a person and a record of how each alert was handled.
• Backups and recovery. Backups that run on a schedule and restores that are tested, with the test results kept.
• Vulnerability and dependency management. Dependency scanning in the pipeline and a record of how findings were fixed. Recent package attacks show why: see npm supply chain attack patterns from 2026.
• Vendors and incidents. A list of the vendors that touch customer data, and an incident response plan your team has actually practised.

The common thread is evidence. In a Type 2 examination the auditor samples records from across the period, so a control that ran but left no trace is hard to prove. Automate what you can, so access, logging and backups produce their own records.

How to get ready for a SOC 2 report

The path is similar for most startups, from scope to the bridge letter between reports.

1. Set the scope. Name the system, the criteria (security first) and the people and vendors involved.
2. Run a gap assessment. Compare what you do today against the criteria and list every missing control or missing record.
3. Fix the gaps. Write the policies you will follow, then build the controls: access, logging, backups, change history and the rest.
4. Get a Type 1 report, if it helps. It confirms the design at one date and gives buyers something early.
5. Run the observation period. The controls run, evidence kept, for the period agreed with your auditor.
6. Receive the Type 2 report. The auditor tests samples from the period and issues the opinion on design and operation.
7. Use a bridge letter between reports. Reports cover past periods, so buyers may ask for a bridge letter for the months since. Microsoft describes these as self-attestations by the service organization, not reports based on an auditor's examination.

SOC 2 is not a one-off. Large providers keep their periods back to back: as of October 2026, Microsoft examines a rolling 12-month period for Office 365 every year and issues bridge letters each quarter, and Google Cloud issues its Type 2 reports quarterly. A startup does not need that pace, but buyers will expect a current report each year.

Choosing an auditor, and what the AICPA flagged in 2026

SOC reports are issued by CPA firms, and the choice matters more than it used to. In May 2026 the Journal of Accountancy reported that the AICPA's Peer Review Board had alerted peer reviewers to SOC 2 engagements that do not respond to each client's own risks. The warning signs it named include identical reports, risk assessments, sample sizes and testing procedures across clients, often at firms that rely heavily on third-party SOC platforms. As of October 2026, the AICPA's SOC suite page also carries a notice that it is looking into anonymously published allegations about the business practices of a compliance vendor that offers SOC services.

For a startup, the lesson is practical. A report that looks like every other report may not satisfy a careful buyer. Ask a prospective auditor how they tailor the risk assessment to your system, how they choose samples, and who on their team will do the testing. Compliance software can help you collect evidence, but the controls and the judgment still have to be real.

How we help startups get ready for SOC 2

We do not issue SOC 2 reports; your CPA firm does. We help with the part that decides how the audit goes: the controls. Our DevOps work adds the controls auditors and enterprise customers ask about, including least-privilege access, secrets management, dependency scanning, tested backups and a change history you can show, built into the way your team already ships.

When the gap is in the code rather than the infrastructure, our code security audit finds and ranks the weaknesses first. Buyers may also run technical due diligence before a large contract or an investment, and the same evidence answers both. The work is led by Thanos Gkanas, our Head of Engineering. Every engagement is under an NDA, and the IP is always yours.
