How to Become a SOC 2 Auditor: Career Path and Requirements

How do you become a SOC 2 auditor?

You build audit skills in IT audit, risk advisory, or security controls testing, then join a licensed CPA firm that performs SOC 2 examinations and work on its engagements under supervision. No personal credential makes someone a SOC 2 auditor on their own, because only a licensed CPA firm signs the report.

1. Study accounting, information systems, cybersecurity, or a related field. Employers set the degree requirement, and some accept equivalent experience.
2. Take an entry role that includes IT general controls testing: internal audit, IT audit, risk advisory, or a security controls team. This is where you learn to inspect evidence, test samples, and write workpapers.
3. Learn the SOC 2 workflow: scoping the system, walkthroughs, sampling, evaluating exceptions, and documenting the result. The AICPA’s Trust Services Criteria are the standard you test against, and our Trust Services Criteria guide summarizes them. The AICPA also sells a basic self-study course, SOC 2 and SOC 3 Planning, Executing, and Reporting, and a SOC 2 Report Walkthrough webcast that lists service auditors with 0 to 2 years of experience among its audience (checked on 2026-10-20).
4. Add a credential that fits the role you want next (see the comparison below).
5. Join a CPA firm’s SOC practice and build supervised experience on real engagements.
6. Pursue CPA licensure if the role you want carries sign-off responsibility. Confirm the rules with your state board of accountancy and the hiring firm.

Does CISA or any other credential let you issue a SOC 2 report?

No. SOC 2 is an AICPA attestation examination, and the AICPA describes SOC reports as issued by a licensed, independent CPA (checked on 2026-10-20). CISA, CISSP, a SOC 2 training certificate, or a Big Four job title does not change who signs.

People without a CPA license still do much of the engagement work. They scope the system, request and inspect evidence, test controls, and draft the write-up, all under the supervision and quality controls of the issuing firm. The buyer’s side of the same rule is in our guide on who can issue a SOC 2 report, and the credential hub compares what each credential proves.

Where does SOC 2 attestation work happen?

It happens at CPA firms, and most of them are not Big Four members. Our directory lists 187 firms that can issue SOC 2 reports, split like this:

Full-service CPA firms treat SOC 2 as one practice among several. Assurance specialists center their practice on SOC 2 and related information assurance. For a job seeker, most employers sit outside the Big Four: full-service CPA firms, where SOC 2 is one practice among several, and assurance specialists, where it is the core. Our directory shows where the work is done, not how many roles are open or what they pay, so treat it as a list of employers to research. You can browse every firm in the SOC 2 auditor directory.

Some firms offer more than SOC 2. 87 firms appear on our SOC 1 auditors list, and 23 are also accredited ISO 27001 certification bodies, listed on our SOC 2 and ISO 27001 page. Working at one of them can expose you to several kinds of assurance engagement. Ask in the interview how staff are assigned across them, since a firm can offer a service without staffing every new hire on it.

Should you start from an accounting or an IT background?

Either works, and each side has a gap to close. Accounting and finance graduates know attestation standards, risk assessment, and workpaper documentation, and need to learn cloud infrastructure, network security, and how software gets built and changed. IT and security professionals know the systems and can talk to engineers, and need to learn audit documentation, test procedures, and the AICPA’s attestation requirements.

The two common first roles teach different things. IT audit or risk advisory inside a public accounting firm puts you in front of many clients and control environments quickly. Internal audit at a technology company shows one complex environment in depth, including how its controls are built and monitored, which helps when you later audit other companies. Both start with IT general controls: user access reviews, change management, and IT operations. Those map onto the Common Criteria, which every SOC 2 report covers. On an engagement you then request evidence, test a sample of it, record the result in a workpaper, and discuss exceptions with the client. Our evidence request list shows what that evidence looks like, and the guide to internal control procedures shows how the tests fit together.

Which credentials are worth getting?

The one that closes the gap between your current experience and the role you want next, and none replaces supervised engagement experience.

ISACA’s CISA rules, as of 2026-10-20: candidates pass the exam, then apply within five years of passing, with five years of information systems auditing, control, or security experience gained in the ten years before they apply. You can sit the exam before you have the experience. ISACA also allows some education to substitute for part of the experience, so check the current application form before you plan your timeline. CPA licensure varies by state in its education, exam, and experience requirements. Our credential hub covers verification, renewal, and what each credential does and does not show.

How do you land the first SOC 2 role?

Target firms whose SOC practice you can name, which the auditor directory helps with, and describe your credential status exactly: licensed, certified, exam passed, or studying. Show work you performed, such as evidence inspection, IT-control testing, or workpaper documentation, without client details.

Ask each employer who supervises new staff, how soon you would work on SOC 2 engagements, and whether the firm supports CPA licensure. A firm’s peer review result also tells you something about its quality system, and our peer review guide explains how to read it. For pay, compare current postings with disclosed salary bands for your location and the type of role. Pay differs between internal audit, advisory, and external attestation, so a single national figure would mislead.
