A budget-conscious buyer’s guide to picking a SOC 2 auditor without overpaying for a name you don’t need.
| Before You Shop SOC 2 reports must come from a licensed CPA firm; the report itself is not more “official” because the firm is bigger or pricier.Boutique and mid-market CPA firms routinely deliver the same Type 1 and Type 2 reports as the household names, often at a fraction of the cost and with far more direct access to the actual auditor.Get at least three quotes. Scope, trust services criteria selected, and company size swing pricing more than brand name does. |
What Is a SOC 2 Audit, and Why Does the Bill Vary So Much?
SOC 2 is an attestation, built by the AICPA, that checks a service organization’s controls against five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. Security is mandatory; the rest depend on what a company’s customers actually ask for. A Type 1 report checks whether controls are designed properly at a single point in time. A Type 2 report checks whether those controls held up over an observation window, usually three to twelve months, and is what most enterprise buyers want to see before they sign a contract.
Only a licensed CPA firm can issue the report, but licensure says nothing about price. A small, focused audit shop and a national firm can both be fully AICPA-accredited. The difference in the invoice usually comes down to overhead, brand premium, and how much of the work gets handed to junior staff instead of the senior auditor a company actually talked to on the sales call.
Why It Pays to Shop Around
Growing SaaS companies often assume the safest move is the biggest, most recognizable audit brand. In practice, a SOC 2 report from a smaller, properly accredited CPA firm carries the same legal weight with enterprise security reviewers. What changes is the price tag, the turnaround time, and whether a company is talking to the person actually running its audit or a rotating account team. For a cost-conscious SaaS company trying to close its first few enterprise deals without blowing the compliance budget, that difference is real money.
Top 8 SOC 2 Audit Firms to Compare
Best for: SaaS companies that want auditors who actually understand cloud architecture, not just a checklist.
Compass Assurance Team is a fully licensed CPA firm, recognized by the AICPA and the State of Rhode Island, that specializes specifically in SOC 1, SOC 2, and SOC 3 attestation reporting. It operates as an affiliate of Compass IT Compliance, a nationwide cybersecurity and compliance firm whose staff includes penetration testers, vCISOs, and security engineers who work with modern SaaS environments every day. That proximity matters during an audit: control walkthroughs and evidence requests come from people who recognize how cloud infrastructure, CI/CD pipelines, and shared-responsibility models actually function, rather than treating the environment as a black box.
At the same time, the two organizations are structured as distinct entities, with the Assurance Team issuing the actual SOC report and Compass IT Compliance handling the broader security and readiness work. That separation keeps the attestation independent while still giving a client a technically fluent audit team that already speaks the language of its engineering staff. For a SaaS company that will eventually need a pen test, a vCISO, or an ISO 27001 certification alongside its SOC 2 report, that combination of independence and technical depth is worth asking about directly.
2. Johanson Group, LLP
Best for: startups and mid-market SaaS companies that want a fixed scope and a fast report.
Johanson Group is a Colorado Springs CPA firm built around SOC 1, SOC 2, SOC 3, ISO 27001, HIPAA, GDPR, CCPA, and PCI DSS work, with a remote, globally distributed audit team. It delivers final SOC 2 reports within four to six weeks and pairs each client with a dedicated auditor and customer success contact rather than a rotating team.
Johanson’s SOC 2 pricing tends to run below the specialist-firm average, which makes it a common pick for seed-to-Series-B SaaS companies working through Drata, Vanta, or Secureframe and looking for a right-sized first audit rather than an enterprise-scale engagement.
3. Render Compliance
Best for: B2B SaaS companies in the 200 to 2,000 employee range who want senior auditors and transparent pricing.
Render Compliance is a Seattle-based, fully licensed CPA firm staffed by CISA- and CPA-certified auditors who specialize specifically in SOC 1 and SOC 2 attestations for B2B SaaS companies. Pricing is published rather than quoted behind a sales call, and reports go out within three weeks of completed fieldwork.
Its differentiator is direct access to senior auditors from kickoff through report delivery, with no handoffs to junior staff mid-engagement. It also offers SOC 2+ reports that map to ISO 27001, HIPAA, or HITRUST in a single audit, along with Microsoft SSPA assessments for companies in the Microsoft partner ecosystem.
4. Decrypt Compliance
Best for: founder-led SaaS companies who want Big 4-trained auditors without a Big 4 invoice.
Decrypt Compliance is a San Jose, California CPA firm founded by Raymond Cheng, whose team includes alumni of EY, PwC, Deloitte, Google, Salesforce, and Tencent. The firm is AICPA-accredited, passed its 2025 AICPA peer review, and is also an accredited ISO 27001 auditor and authorized HITRUST assessment provider.
Decrypt is independent rather than private-equity-owned, unlike some of its larger competitors, and Cheng stays on every engagement from start to finish. The firm works alongside existing Vanta or Drata evidence rather than asking clients to start over, and it serves B2B SaaS, fintech, healthcare-adjacent software, and AI companies.
5. 360 Advanced
Best for: SaaS companies that want SOC 2 bundled with a broader cybersecurity and privacy program.
360 Advanced is a St. Petersburg, Florida-based firm operating as a licensed CPA firm (360 Advanced, Inc.) alongside an affiliated cybersecurity practice, registered with the PCAOB. It covers SOC 1, SOC 2 Type 1 and Type 2, SOC 2+ add-ons for HIPAA, HITRUST, CSA STAR, and FFIEC, plus ISO 27001, PCI DSS, FedRAMP, and CMMC.
The firm markets a platform-neutral, relationship-focused approach and serves clients ranging from early-stage startups to Fortune 500 companies. Client testimonials on its site highlight long-term continuity across multiple audit cycles rather than a one-and-done engagement.
6. Constellation GRC
Best for: early-stage SaaS companies that want speed and a low-friction evidence process.
Constellation GRC is a California-based, AICPA peer-reviewed CPA firm whose team draws on Big 4 audit experience. It focuses specifically on removing friction from the SOC 2 process, with automated evidence collection and fast scheduling and turnaround built for startups.
Reviews cite direct, responsive communication with the firm’s audit lead throughout the engagement, and the firm frequently picks up clients referred through Vanta’s partner network. It is a fit for companies chasing a Type 1 quickly to unblock a deal, with less emphasis on serving large, complex enterprises.
7. Insight Assurance
Best for: SaaS companies with international customers who need a report that satisfies both U.S. and overseas due diligence.
Insight Assurance is a Tampa, Florida-founded firm built by former Big 4 professionals, with audit operations now spanning the Americas, EMEA, and APAC. It holds accreditations across SOC 1, 2, and 3, ISO 27001, PCI DSS as a Qualified Security Assessor, HITRUST, CMMC (as a C3PAO), and FedRAMP (as a 3PAO).
It weaves the AICPA Trust Services Criteria into an ISAE 3000-aligned report, which lets a SaaS company satisfy both U.S. enterprise buyers and international customers from a single engagement. Insight Assurance serves close to 2,000 clients globally and has appeared on the Inc. 5000 list of fastest-growing companies.
8. PYA
Best for: SaaS companies that want a nationally recognized, employee-owned firm with audit depth beyond SOC 2 alone.
PYA is a nationally recognized, privately held CPA and consulting firm that has been named an INSIDE Public Accounting Top 100 firm for ten consecutive years. Its SOC 2 practice serves cloud and SaaS companies specifically, with auditors who hold both CPA and CISA credentials, and it can layer in additional frameworks such as NIST for companies in regulated industries.
PYA’s independence, it is privately owned rather than investor-backed, is part of why clients get thorough, unhurried audit work instead of a checklist exercise. The firm offers a readiness assessment ahead of the formal audit to flag gaps before fieldwork begins, plus ongoing support for annual renewals.

How to Compare Quotes Without Overpaying
- Get an itemized scope: A vague quote is a red flag. Ask for pricing broken out by readiness assessment, Type 1 or Type 2 fieldwork, and report delivery.
- Ask who actually does the work: Ask whether the person on the sales call is the person doing the audit, or whether the work gets handed to a junior team after signing.
- Check platform familiarity: If a company already uses Drata, Vanta, or Secureframe, confirm the firm has real experience pulling evidence from that specific platform.
- Account for the observation period: A first SOC 2 Type 2 typically needs a three to twelve month observation period before fieldwork even starts. Factor that into the total cost of getting a report in hand, not just the audit fee.
- Ask about bundling: If a company plans to pursue ISO 27001, HIPAA, or PCI DSS later, ask what a combined or SOC 2+ engagement would cost compared to hiring separate firms for each one.
Frequently Asked Questions
Does a bigger audit firm mean a more credible SOC 2 report?
Not inherently. A SOC 2 report only carries weight because it comes from a licensed, AICPA-accredited CPA firm. A boutique firm’s report satisfies the same enterprise security reviewers as a report from a much larger firm, as long as the firm is properly accredited.
How much should a first SOC 2 audit cost?
Pricing depends heavily on company size, the number of Trust Services Criteria selected, and system complexity. Boutique and specialist firms often quote noticeably less than large national firms for a comparable first-time Type 1 or Type 2 engagement, so it is worth collecting more than one quote before committing.
Is SOC 2 Type 1 or Type 2 better for closing enterprise deals?
Type 1 proves controls are designed correctly at a single point in time and can unblock a deal quickly. Type 2 proves those controls operated effectively over a period of months and is what most enterprise buyers ultimately require for a renewal or a larger contract.
Can one firm handle SOC 2 plus other frameworks like ISO 27001 or HIPAA?
Many of the firms above offer combined or mapped audits, sometimes called SOC 2+, that address multiple frameworks in a single engagement. That can be considerably cheaper than hiring a separate firm for each certification a company eventually needs.
Do compliance automation platforms replace the need for an audit firm?
No. Platforms like Drata, Vanta, and Secureframe help collect and organize evidence, but the actual SOC 2 report still has to be issued by an independent, licensed CPA firm. Most of the firms above work directly with these platforms rather than competing with them.
