Choosing among SOC consulting firms is not only a procurement exercise. The provider you select affects your audit scope, evidence quality, internal workload, customer deadlines, and future compliance plans.
The market includes CPA firms, specialist auditors, readiness consultants, compliance platforms, and large advisory groups. These providers don’t offer the same service. A startup preparing for its first SOC 2 Type 2 report needs a different engagement than a global company combining SOC 2 with ISO 27001, HIPAA, PCI DSS, or FedRAMP requirements.
This guide compares the main provider groups active in 2025 and 2026, explains typical costs, and shows how to select a firm based on your size, scope, budget, and required outcome.
What SOC consulting firms actually provide
SOC 2 work has several separate stages. Confusing them creates problems before the engagement starts.
A readiness consultant reviews your controls, identifies gaps, helps assign ownership, and supports remediation. The consultant may help configure policies, improve access reviews, organize evidence, and prepare your team for the audit.
An audit or attestation firm performs the independent examination. It evaluates whether your controls meet the selected Trust Services Criteria and issues the final SOC 2 report. The audit firm cannot promise a passing result before it completes its work.
Compliance software vendors support evidence collection and workflow management. Vanta, Drata, Secureframe, Sprinto, LogicGate, and similar platforms can reduce manual work. They don’t automatically replace an independent audit.
SOC 2 also isn’t a certification in the same way as ISO 27001. A qualified CPA firm issues an attestation report. Buyers should be cautious when a provider uses “SOC 2 certification” as a simple sales phrase.
The report type matters too:
- A Type 1 report evaluates whether controls are suitably designed at a specific date.
- A Type 2 report evaluates design and operating effectiveness over a review period, often three to twelve months.
- The selected Trust Services Criteria can include security, availability, processing integrity, confidentiality, and privacy.
Your customer commitments should determine the scope. A company selling a hosted application may need security and availability. A healthcare provider may also need privacy and confidentiality controls. A payment service may need SOC 2 alongside PCI DSS.

How this 2025 and 2026 comparison was assessed
This comparison uses provider visibility across 2025 and 2026 market listings, stated service models, known specialization, customer segment, and reported pricing ranges. It does not treat a ranking as proof that one firm is better for every buyer.
The firms are grouped by operating model:
- Specialist SOC and security audit firms.
- Mid-market accounting and advisory firms.
- Large professional services firms.
- Readiness consultants and compliance platforms.
The practical criteria are more important than a simple ranking. Buyers should assess:
- Whether the provider can issue the required attestation report.
- Experience with your industry and technology stack.
- Type 1 and Type 2 delivery experience.
- Ability to support adjacent frameworks.
- Independence between readiness work and audit work.
- Auditor availability and review-period timing.
- Evidence requirements for cloud, application, identity, and infrastructure controls.
- Total cost, including software, consulting, remediation, and audit fees.
- The level of internal effort required from security, engineering, HR, legal, and finance teams.
A provider may be well known and still be a poor fit. A large enterprise firm may bring useful regulatory experience but create unnecessary cost for a 40-person SaaS company. A low-cost specialist may be efficient but lack experience with a complex environment or multinational control structure.
Specialist SOC audit firms to consider
Specialist providers focus heavily on SOC reports, security assessments, and related compliance work. They often have clearer processes for technology companies and more predictable engagement structures than large generalist firms.
Schellman
Schellman is one of the most recognised specialist names in the US SOC 2 market. Its work covers SOC 1, SOC 2, SOC 3, ISO 27001, PCI DSS, HITRUST, and other assurance programs.
The firm is often considered by cloud providers, software companies, and larger technology businesses that need a recognised audit brand. It can suit buyers with several customer assurance requirements and a mature security function.
Published 2026 comparisons place Schellman in a broad specialist pricing band, with estimates around $20,000 to $100,000 and timelines of roughly three to twelve weeks. These figures are market estimates, not quotes. Scope, report period, system complexity, and evidence quality can change the final price.
A-LIGN
A-LIGN provides compliance, cybersecurity, privacy, and risk services. It is frequently listed among leading SOC 2 providers and has a technology-enabled delivery model.
A-LIGN may suit companies that need SOC 2 alongside ISO 27001, HIPAA, PCI DSS, or privacy assessments. It is also a practical option for organisations that want a structured audit process and a provider with broad compliance coverage.
Some 2026 market comparisons place its estimated pricing around $15,000 to $50,000, with timelines of three to twelve weeks. A-LIGN’s own service information should take priority during procurement. Buyers should ask whether the quoted timeline covers readiness, fieldwork, report review, or the complete engagement.
See A-LIGN’s compliance and cybersecurity services for its current service scope.
Linford & Company
Linford & Company is a specialist audit firm known for SOC and HIPAA work. It is often considered by technology businesses that want a focused provider rather than a general advisory firm.
The firm’s fit depends on your required report, customer expectations, and need for related frameworks. A specialist audit firm can offer direct technical experience, but procurement teams should still check availability for the requested audit period.
Ask for examples involving your hosting model, such as AWS, Microsoft Azure, Google Cloud, or a hybrid environment. Also ask how the firm handles software development, privileged access, vulnerability management, incident response, and vendor risk evidence.
KirkpatrickPrice
KirkpatrickPrice is a specialist security compliance firm with a strong presence in SOC 2 audit services. It is frequently associated with startups, SaaS providers, and growth-stage technology companies.
Published estimates for 2026 place its typical range around $12,000 to $45,000, with timelines of three to eight weeks. The actual timeline depends on whether the company is audit-ready and whether the review is Type 1 or Type 2.
KirkpatrickPrice can be a useful option when the buyer wants a focused audit provider and a defined compliance process. The buyer still needs to confirm auditor independence, peer review status, report acceptance among key customers, and experience with the company’s control environment.
BARR Advisory
BARR Advisory supports SOC 1, SOC 2, and other security and compliance programs. It is often considered by technology and service organisations that need audit support with broader information security requirements.
Market estimates place BARR Advisory around $15,000 to $50,000, with longer reported timelines of eight to sixteen weeks. That longer schedule may reflect more involved planning, review, or scope requirements.
The firm may be suitable when the buyer wants SOC 2 combined with ISO 27001 or a wider security program. Ask how much work the internal team must complete before fieldwork begins. A low quoted fee can become expensive if control owners spend months preparing evidence manually.
Thoropass
Thoropass combines compliance software with audit services. This model can help companies manage evidence, policy workflows, and audit communication in one environment.
Thoropass is often positioned toward startups and growth-stage companies that want a more managed process. Published 2026 comparisons list estimated pricing around $12,000 to $30,000 and timelines of two to six weeks.
The software-plus-audit model needs careful review. Confirm which platform features are included, whether the audit is performed by the same organisation, and how the provider handles independence. Also confirm what happens if you later move to another auditor or compliance platform.
Johanson Group and Prescient Security
Johanson Group is a specialist provider associated with SOC and ISO work. It may suit smaller companies that need a focused assessment without a large advisory structure.
Prescient Security also appears frequently in specialist audit lists. Its services cover SOC 2 and other security assessment requirements. One market source attributes more than 3,500 SOC 2 audits to the firm, but buyers should verify current figures and ask for references that match their environment.
Specialist firms can be efficient. They are not automatically interchangeable. The best option depends on your required report, customer deadline, control maturity, industry, and internal capacity.
Mid-market and enterprise providers
Large accounting and advisory firms can be appropriate when SOC 2 is part of a wider governance or regulatory program.
RSM US, Armanino, BDO, Grant Thornton, WithumSmith+Brown, Protiviti, Coalfire, and ControlCase appear in 2025 and 2026 market discussions. These providers may offer audit, risk advisory, technology consulting, privacy, internal audit, and regulatory services.
RSM is often considered by mid-market organisations that need more support than a small specialist can provide. Armanino may suit companies that want accounting, risk, and compliance services from one firm. BDO, Grant Thornton, Withum, and Protiviti can support broader internal control and risk programs.
The Big Four firms, Deloitte, PwC, EY, and KPMG, are usually considered by larger enterprises. They can support complex international structures and multiple frameworks. Their costs are usually higher, and the engagement may involve more formal governance, documentation, and review layers.
Published 2026 estimates place mid-tier SOC 2 work around $25,000 to $110,000. Big Four engagements can range from roughly $45,000 to more than $400,000, depending on scope. These numbers are broad market ranges. They aren’t suitable for budgeting without a formal proposal.
The main reason to choose a large firm is not brand recognition alone. It is the ability to manage connected risks across business units, regions, systems, and regulatory programs.
Readiness consulting versus audit execution
A readiness consultant and an audit firm have different responsibilities. Your procurement process should separate them.
Readiness work usually covers control mapping, policy development, risk assessment, evidence planning, remediation support, staff interviews, and audit preparation. The consultant may work directly with your security and engineering teams.
The audit firm performs independent testing. It reviews evidence, interviews control owners, tests samples, evaluates exceptions, and issues the report. It should not make management decisions for you or operate the controls it later tests.
Some companies hire one provider for readiness and another for audit. This can create a stronger separation of duties and give the audit firm greater independence. Other companies use a combined platform and audit model for speed and lower coordination overhead.
Neither model is automatically correct. A small company with limited compliance experience may need hands-on readiness help. A mature security team may only need an audit firm. A fast-growing SaaS company may need software to collect evidence and assign control ownership.
Compliance platforms can automate reminders, connect to cloud and identity systems, and store evidence. They don’t fix weak access governance, incomplete incident response, poor vendor oversight, or unclear ownership.
A readiness engagement should leave your team with working controls. It should not only produce a folder of policies before the audit.
SOC 2 consulting costs and timelines in 2026
The total cost usually includes readiness, technology, internal labour, audit fees, and remediation. A narrow audit quote is not the same as the full first-year cost.
| Engagement type | Reported 2026 market range | Common use |
|---|---|---|
| Gap assessment | A few thousand to about $15,000 | Identify control and evidence gaps |
| Readiness build | $20,000 to $75,000 or more | Build policies, controls, and evidence processes |
| Specialist Type 2 audit | $15,000 to $70,000 | Independent audit by a specialist |
| Mid-tier or national audit | $25,000 to $110,000 | Broader scope or related frameworks |
| Big Four audit | $45,000 to $430,000 | Enterprise and multi-framework programs |
| First-year total program | $30,000 to $100,000 or more | Readiness, tools, remediation, and audit |
Type 1 is usually faster because it assesses controls at one point in time. Type 2 requires an operating period, so planning must start earlier.
A company with strong controls and clean evidence may complete the audit quickly. A company with inconsistent access reviews, undocumented changes, or weak vendor records may need months of remediation.
Ask each provider to separate professional fees, software fees, expenses, retesting, and support after the report. Ask what happens if the scope changes. Ask whether the quote includes a bridge letter or only the final report.
How to choose the right provider
Start with the buyer’s requirement, not a firm’s ranking.
A startup preparing for customer security reviews may prioritise speed, clear evidence requests, and a manageable price. A mid-market company may need SOC 2 plus ISO 27001, HIPAA, PCI DSS, or privacy support. An enterprise may prioritise global delivery, regulatory experience, and a consistent methodology across subsidiaries.
Build a short list of three to five providers. Give each firm the same information:
- Company size and locations.
- Products and services in scope.
- Cloud providers and critical systems.
- Number of employees and privileged users.
- Target Trust Services Criteria.
- Type 1 or Type 2 requirement.
- Desired audit period.
- Customer or procurement deadline.
- Related frameworks already in place.
- Internal staff available for control ownership.
Then ask direct questions. Is the firm a CPA firm authorised to issue the report? Does it maintain a current AICPA peer review? Who performs fieldwork? What experience does the team have with your cloud and software development model? How are exceptions handled? What evidence is required for each major control?
Request a sample evidence list and a draft timeline. Ask for two references with similar system scope. Ask whether the same auditor will remain available throughout the review period.
Do not select a provider only because it promises a quick report. A rushed audit can expose missing controls late in the process. It can also create problems when customers review the report.
A useful comparison should score technical fit, independence, delivery model, schedule, communication, scope clarity, and total cost. Price should be one field in the assessment. It should not be the assessment.
Warning signs during procurement
Some problems appear before the contract is signed.
Be cautious when a provider promises that you will pass without reviewing your systems. No legitimate auditor can guarantee an attestation result before testing is complete.
Be cautious when the proposal uses “certification” without explaining the report type, Trust Services Criteria, review period, and issuing firm.
Be cautious when readiness and audit responsibilities are unclear. The contract should state who owns remediation, who operates controls, who tests them, and who issues the report.
Be cautious when a provider cannot explain evidence requirements in practical terms. Your team needs clear requests for access reviews, change management records, incident testing, risk assessments, vendor reviews, and security training records.
Be cautious when the price excludes common work. Confirm whether retesting, scope changes, platform fees, report updates, and customer questionnaires cost extra.
Finally, check whether the provider’s timeline matches your Type 2 period. A two-week sales timeline doesn’t mean you can obtain a Type 2 report in two weeks.
When outside security support is also needed
SOC 2 readiness often exposes a people problem. A company may have written policies but no experienced owner for identity governance, cloud security, application security, or incident response.
The audit report won’t fill that capability gap. It records whether controls were designed and operated. Your team still needs people to run the controls after the audit.
This is where specialist support can help. If your company needs a senior security hire, temporary control ownership, technical validation, or external attack-surface testing, Book A Call With Us to discuss the requirement.
The right support may be an audit firm, a readiness consultant, a compliance platform, an internal hire, or a combination. The choice should follow the actual gap.
Conclusion
The top SOC consulting firms in 2025 and 2026 fall into different groups. Schellman, A-LIGN, Linford & Company, KirkpatrickPrice, BARR Advisory, Thoropass, and Johanson Group are specialist options. RSM, Armanino, BDO, Grant Thornton, and Withum may suit mid-market buyers. Deloitte, PwC, EY, and KPMG are usually considered for larger enterprise programs.
The right provider depends on company size, scope, budget, framework needs, and service type. Confirm whether you need readiness consulting, independent audit services, compliance automation, or additional security capability. No firm can provide a legal, audit, or certification guarantee before completing the required work.
A strong provider makes the audit process clear. A strong internal program keeps the controls working after the report is issued.
