What does a SOC 2 compliance consultant do?
A compliance consultant builds and runs your compliance program: scoping, control design, policy, evidence, and remediation, frequently across SOC 2 plus ISO 27001, HIPAA, or PCI at the same time. They make you audit-ready and keep the program running; the SOC 2 report itself still comes from an independent CPA firm.
A platform and a consultant are not alternatives, they do different jobs. A GRC platform (Vanta, Drata, Secureframe) automates evidence collection and cross-maps controls; the consultant designs the program, sets scope, writes policies that match how you actually operate, and manages the auditor. Most companies need both. If you only need an audit-focused gap assessment, a readiness firm may be the lighter fit; if you want to understand the role before you shortlist, the compliance-consultant guide walks through it.
When should you hire a consultant instead of going direct to an auditor?
Hire a compliance consultant when you need the program built and operated, not just assessed, or when you are running multiple frameworks and want one team to de-duplicate the work. Go direct to an auditor when controls are already operating and you only need the report.
The multi-framework case is where a consultancy earns its fee. Because SOC 2, ISO 27001, and HIPAA share most of their underlying controls, a common-control approach runs three frameworks for roughly 1.4 to 1.6 times the cost of one rather than three times. Most engagements that start as pure SOC 2 touch ISO 27001 within the first year anyway, once a European enterprise deal appears. The constraint to respect throughout: whoever designs, implements, or operates your controls cannot also be the firm that audits them, so keep the consultancy and the CPA firm separate.
How should you compare compliance consultancies?
Compare on scoping depth, engagement model, and independence. A useful proposal scopes from your architecture rather than a template, names the frameworks covered, says what is one-time versus ongoing, explains how remediation is tracked, and commits to a clean hand-off to an independent auditor.
Fixed-price on a defined scope beats hourly, which rewards scope creep. Ask for a sample gap report and remediation plan, confirm whether the same senior people stay on after kickoff, and check that the firm has taken companies through SOC 2 specifically, not only adjacent frameworks. Treat "audit-ready in two weeks" and "we guarantee you will pass" as warnings: the first means templates rather than a program, and the second misunderstands that the audit is independent.
