Understanding the true cost of a SOC 2 audit requires looking well beyond the auditor’s invoice. Organisations that budget only for the CPA firm’s fees consistently find themselves surprised by the total spend — and those surprises often come at the worst possible time, midway through the engagement when scope changes and remediation work start stacking up.
This guide breaks down every cost component of a SOC 2 audit in 2026, provides realistic ranges by company size and report type, identifies the hidden expenses that catch most organisations off guard, and outlines strategies for reducing costs without cutting corners.
Total cost components
A SOC 2 audit has six distinct cost categories. Most organisations focus on the first and underestimate the rest.
Auditor fees
This is the direct cost of engaging a licensed CPA firm to perform the examination and issue the SOC 2 report. Fees vary based on your organisation’s size, infrastructure complexity, the number of Trust Service Criteria in scope, and the auditor’s market positioning.
| Report type | Typical range |
|---|---|
| Type 1 | £15,000 – £50,000 |
| Type 2 | £25,000 – £80,000 |
| Type 2 renewal | £20,000 – £65,000 |
Auditor fees are influenced by several factors: the number of controls in your control matrix, the complexity of your technology stack (multi-cloud environments cost more than single-provider setups), the number of subservice organisations in scope, and whether the firm needs to perform on-site work. Larger CPA firms with established SOC 2 practices tend to charge at the higher end but often deliver faster turnaround times and reports that carry more weight with enterprise customers.
Readiness assessment
A readiness assessment is a pre-audit review — typically conducted by your audit firm or a separate consultancy — that identifies gaps between your current controls and what the auditor will expect during the formal examination.
- Cost range: £5,000 – £25,000
- Typical duration: 2 to 4 weeks
While technically optional, a readiness assessment is strongly recommended for first-time audits. Skipping it to save money frequently backfires: organisations that go straight into a formal audit without one are far more likely to encounter exceptions in their report or need to pause the engagement for remediation.
Compliance tooling and automation
Compliance platforms automate evidence collection, policy management, control monitoring, and audit workflows. They have become a near-standard part of the SOC 2 toolkit, particularly for technology companies.
- Annual cost range: £10,000 – £60,000 per year
- Enterprise platforms: £40,000 – £100,000+ per year
The pricing model varies: some platforms charge per user, others per framework or per number of integrations. When evaluating cost, factor in implementation time (typically 2 to 6 weeks) and the ongoing effort required to maintain integrations and respond to alerts.
Internal team time
This is often the single largest cost of a SOC 2 audit, yet it rarely appears in anyone’s budget. Your internal team — security, engineering, IT, HR, and leadership — will spend significant time on policy development, control implementation, evidence gathering, auditor walkthroughs, and remediation.
| Role | Estimated hours (first audit) | Estimated hours (renewal) |
|---|---|---|
| Compliance lead / project owner | 300 – 500 | 150 – 250 |
| Engineering / DevOps | 100 – 300 | 50 – 120 |
| IT / system administration | 80 – 200 | 40 – 100 |
| HR / people operations | 30 – 60 | 15 – 30 |
| Executive sponsor | 20 – 40 | 10 – 20 |
For a first-time audit, organisations should expect 500 to 1,000+ total hours of internal effort. At a blended internal rate of £80 to £150 per hour, that translates to £40,000 to £150,000 in staff time — often exceeding every other cost category combined.
Remediation costs
Gaps identified during your readiness assessment or the audit itself require remediation. Common remediation activities include:
-
Implementing or reconfiguring technical controls (endpoint protection, encryption, logging)
-
Developing or rewriting policies and procedures
-
Deploying new tools (SIEM, MDM, vulnerability scanning)
-
Addressing infrastructure gaps (network segmentation, backup systems)
-
Cost range: £5,000 – £50,000+ depending on maturity
-
Timeline impact: 2 to 8 weeks of additional preparation time
Organisations with mature security programmes may spend very little on remediation. Those building a control environment from scratch should budget heavily for this category.
Penetration testing
While not strictly required by the SOC 2 standard, penetration testing is expected by most auditors as evidence supporting the Security criterion. Many customers also expect to see recent penetration test results alongside your SOC 2 report.
- Standard web application pentest: £5,000 – £20,000
- Network and infrastructure pentest: £10,000 – £30,000
- Comprehensive assessment (application + infrastructure + API): £15,000 – £50,000
Annual retesting is standard practice. Some organisations reduce costs by using a combination of automated vulnerability scanning (continuous) and manual penetration testing (annual).
Cost by report type: Type 1 vs Type 2
The choice between Type 1 and Type 2 has a significant impact on total cost, and the difference extends well beyond the auditor’s fee.
| Cost category | Type 1 | Type 2 |
|---|---|---|
| Auditor fees | £15,000 – £50,000 | £25,000 – £80,000 |
| Readiness assessment | £5,000 – £25,000 | £5,000 – £25,000 |
| Compliance tooling (annual) | £10,000 – £60,000 | £10,000 – £60,000 |
| Internal team time | £25,000 – £80,000 | £40,000 – £150,000 |
| Remediation | £5,000 – £50,000 | £5,000 – £50,000 |
| Penetration testing | £5,000 – £30,000 | £5,000 – £30,000 |
| Total estimated range | £65,000 – £295,000 | £90,000 – £395,000 |
The primary cost difference between Type 1 and Type 2 lies in auditor fees and internal team time. A Type 2 audit requires your team to maintain controls and collect evidence continuously over the observation period, which demands sustained effort rather than a one-time sprint. The auditor also performs more extensive testing, sampling evidence across the full observation window rather than examining a single point in time.
Many organisations pursue a Type 1 first to satisfy immediate customer requirements, then transition to Type 2 for subsequent audits. This staged approach spreads costs across two budget cycles and allows the team to build operational muscle before committing to continuous compliance.
Cost by company size
Organisation size is one of the strongest predictors of total SOC 2 cost. Larger organisations have more complex environments, more employees to train, more systems to integrate, and more controls to test.
| Category | Startup (<50 employees) | Mid-market (50–500 employees) | Enterprise (500+ employees) |
|---|---|---|---|
| Auditor fees (Type 2) | £20,000 – £40,000 | £35,000 – £65,000 | £55,000 – £100,000+ |
| Readiness assessment | £5,000 – £10,000 | £10,000 – £20,000 | £15,000 – £30,000 |
| Compliance tooling | £10,000 – £25,000/yr | £20,000 – £50,000/yr | £40,000 – £100,000+/yr |
| Internal team time | £20,000 – £50,000 | £50,000 – £120,000 | £100,000 – £250,000+ |
| Remediation | £5,000 – £20,000 | £10,000 – £40,000 | £20,000 – £80,000 |
| Penetration testing | £5,000 – £15,000 | £10,000 – £25,000 | £20,000 – £50,000 |
| Total first-year estimate | £65,000 – £160,000 | £135,000 – £320,000 | £250,000 – £610,000+ |
Startups typically benefit from simpler infrastructure (often a single cloud provider), fewer employees, and a narrower scope. The challenge is that they also have fewer people available to do the work, which means each team member carries a disproportionate compliance burden.
Mid-market organisations often face the highest cost-to-value tension. They are large enough to have complex environments but may not yet have dedicated compliance staff. Hiring or contracting a compliance lead is often cost-effective at this stage.
Enterprise organisations have the budget and headcount to absorb audit costs, but the scope and complexity of their environments drive costs significantly higher. Multiple business units, legacy systems, international data flows, and complex vendor ecosystems all increase the auditor’s workload and the internal effort required.
Cost by number of Trust Service Criteria
Every SOC 2 audit must include the Security criterion (Common Criteria). The remaining four — Availability, Processing Integrity, Confidentiality, and Privacy — are optional and add incremental cost.
| Criteria in scope | Auditor fee impact | Internal effort impact |
|---|---|---|
| Security only | Baseline | Baseline |
| Security + Availability | +10–20% | +15–25% |
| Security + Availability + Confidentiality | +20–35% | +25–40% |
| All five criteria | +40–60% | +50–80% |
The cost increase comes from additional controls that must be implemented, documented, and tested. Each additional criterion adds control objectives that require evidence, and the auditor must evaluate each one independently.
Recommendation: Start with the criteria your customers actually require. Most B2B SaaS companies need Security and Availability. Add Confidentiality if you handle sensitive customer data. Processing Integrity and Privacy are less commonly requested but may be necessary in specific industries (financial services, healthcare-adjacent services).
Hidden costs most companies miss
Beyond the obvious line items, several costs routinely catch organisations off guard:
Legal review. Your legal team or outside counsel may need to review the SOC 2 report before distribution. Some organisations also require legal review of the system description and management assertion. Budget £2,000 to £10,000 for legal involvement.
Employee training. Security awareness training is a common control requirement. Whether you use an existing platform or purchase a new one, plan for £2,000 to £15,000 annually, plus the productivity cost of employee time spent in training.
Policy development. If your organisation lacks documented security policies, developing a comprehensive policy library (information security, acceptable use, incident response, data classification, vendor management, etc.) can cost £5,000 to £20,000 when done by an external consultant.
Vendor management programme. SOC 2 requires that you assess and monitor your critical vendors. Building a vendor risk management programme — including risk assessments, contract reviews, and ongoing monitoring — has both direct costs (tooling, consulting) and ongoing operational costs.
Opportunity cost. Engineering hours spent on compliance are hours not spent on product development. For early-stage companies in particular, this trade-off is real and should be factored into the decision.
Report distribution systems. You will need a secure way to share your SOC 2 report with customers and prospects. Some organisations build an NDA-gated portal; others use third-party platforms. Either approach has a cost.
How automation reduces costs
Compliance automation platforms have become a critical cost-reduction lever for SOC 2 audits. The ROI is clearest in three areas:
Evidence collection. Manual evidence gathering — taking screenshots, exporting logs, compiling spreadsheets — is the most time-consuming part of audit preparation. Automation platforms integrate directly with your cloud providers, identity systems, HR tools, and code repositories to collect evidence continuously. This alone can save 200 to 400 hours of internal effort per audit cycle, translating to £16,000 to £60,000 in staff time savings.
Continuous monitoring. Rather than discovering control failures during the audit, automation platforms alert you to issues in real time. This reduces the risk of exceptions in your report and eliminates the last-minute scramble to remediate gaps discovered during the audit window.
Auditor efficiency. When your auditor can access organised, timestamped evidence through a platform rather than requesting it piecemeal via email, the audit moves faster. Many auditors offer reduced fees (10 to 20 percent) when the organisation uses a recognised compliance platform, because it reduces their testing time.
Estimated net savings from automation:
| Cost category | Without automation | With automation | Savings |
|---|---|---|---|
| Internal staff time | £50,000 – £150,000 | £25,000 – £80,000 | 40–50% |
| Auditor fees | £25,000 – £80,000 | £20,000 – £65,000 | 10–20% |
| Remediation (from early detection) | £10,000 – £50,000 | £3,000 – £15,000 | 60–70% |
| Platform cost | — | £10,000 – £60,000 | — |
| Net impact | £15,000 – £100,000+ saved |
The payback is strongest for mid-market organisations where internal staff time is expensive and limited. Startups benefit from the structure and speed; enterprises benefit from the scalability across multiple frameworks and business units.
How to evaluate auditor pricing
Not all SOC 2 auditor proposals are directly comparable. When evaluating pricing, look beyond the headline fee:
Scope clarity. Ensure the proposal specifies exactly which Trust Service Criteria are included, the expected number of controls, and the observation period length. Vague scoping is the most common source of cost overruns.
What is included. Confirm whether the proposal covers a readiness assessment, management letter, or only the formal examination. Some firms bundle readiness into the audit fee; others charge separately.
Change order policies. Understand how the firm handles scope changes. If your environment proves more complex than initially assessed, will you face additional charges? What triggers a change order?
Experience with your industry and tech stack. Auditors familiar with your cloud provider, industry, and typical SaaS architecture work faster and ask fewer redundant questions. This efficiency translates directly into lower internal costs even if the auditor’s fee is slightly higher.
Report turnaround time. Delays in receiving your final report can stall sales deals. Ask for a committed timeline and understand what happens if the auditor misses it.
Firm size and reputation. Top-tier firms charge more but their reports carry weight with enterprise buyers. Smaller, specialised firms often deliver excellent quality at lower cost but may be less recognisable to your customers’ procurement teams.
The cost of not having SOC 2
The decision to pursue SOC 2 is often framed as a cost. It is more accurately understood as an investment — and the cost of not having a current report is frequently higher than the audit itself.
Lost and delayed deals. Enterprise buyers increasingly require a current SOC 2 Type 2 report before signing contracts. Without one, deals worth £100,000 to £1,000,000+ can stall for months or be lost entirely to competitors who have the report ready. Even a single lost deal can exceed the total cost of the audit many times over.
Extended sales cycles. Without SOC 2, your sales team must respond to lengthy security questionnaires — often 200 to 500 questions — for every prospect. Each questionnaire consumes 20 to 80 hours of engineering and security team time. A SOC 2 report answers the majority of these questions proactively.
Higher customer acquisition costs. The sales friction created by missing compliance documentation increases your cost per acquisition and puts pressure on your go-to-market timeline.
Competitive disadvantage. In markets where SOC 2 is table stakes — B2B SaaS, cloud infrastructure, fintech, healthtech — operating without a report positions you as less mature than competitors who have one.
Partnership limitations. Technology partnerships, marketplace listings, and integration partnerships increasingly require SOC 2 as a prerequisite. Without it, your distribution channels may be constrained.
Year-over-year costs: first audit vs renewal
SOC 2 is not a one-time expense. Understanding the cost trajectory helps with long-term budgeting.
| Cost category | Year 1 (first audit) | Year 2 (renewal) | Year 3+ |
|---|---|---|---|
| Auditor fees | £25,000 – £80,000 | £20,000 – £65,000 | £20,000 – £60,000 |
| Readiness assessment | £5,000 – £25,000 | £0 – £5,000 | £0 |
| Compliance tooling | £10,000 – £60,000 | £10,000 – £60,000 | £10,000 – £60,000 |
| Internal team time | £40,000 – £150,000 | £20,000 – £80,000 | £15,000 – £70,000 |
| Remediation | £5,000 – £50,000 | £2,000 – £15,000 | £1,000 – £10,000 |
| Penetration testing | £5,000 – £30,000 | £5,000 – £25,000 | £5,000 – £25,000 |
| Total | £90,000 – £395,000 | £57,000 – £250,000 | £51,000 – £225,000 |
Key observations:
- Total costs typically decrease by 20 to 40 percent from Year 1 to Year 2 as remediation drops and internal processes mature.
- Auditor fees decrease modestly (10 to 20 percent) as the firm gains familiarity with your environment and requires less ramp-up time.
- Compliance tooling costs remain stable, representing an increasing share of the total budget over time.
- Internal team time drops significantly after the first audit, provided you maintain controls continuously rather than scrambling before each audit cycle.
- By Year 3, the total cost often stabilises. Further reductions come primarily from process maturity and automation improvements.

Tips for building your budget:
- Use the company size table above to set your initial ranges, then adjust based on your specific circumstances.
- Add a 10 to 15 percent contingency for scope changes and unexpected remediation work.
- If this is your first audit, weight your estimates toward the higher end of each range. First-time audits nearly always cost more than expected.
- Factor in the full cost of internal team time, not just the direct expenses. This is the line item most organisations underestimate.
- If you are evaluating compliance platforms, request pricing from multiple vendors and compare total cost of ownership, including implementation, training, and ongoing support.
- Plan for Year 2 costs at the time you budget Year 1. SOC 2 is an annual commitment, and building it into your operating budget from the start avoids difficult renewal conversations.
Making SOC 2 costs work for your organisation
The organisations that manage SOC 2 costs most effectively share a few common practices. They start with a narrow scope — Security only, or Security plus Availability — and expand in subsequent years as needed. They invest in automation early, recognising that the upfront platform cost pays for itself within the first audit cycle. They choose an auditor based on fit and efficiency rather than the lowest fee. And they treat compliance as a continuous programme rather than an annual project, which reduces the intensity and cost of each renewal cycle.
SOC 2 is a significant investment. It is also, for most B2B technology companies, a non-negotiable requirement for growth. The goal is not to minimise the cost — it is to maximise the return by building a compliance programme that scales with your business and pays dividends in faster sales cycles, stronger customer trust, and a more resilient security posture.
