For many Series B SaaS companies, achieving SOC 2 Type II compliance is no longer just a security milestone—it’s a business requirement. Enterprise customers, financial institutions, healthcare organizations, and government contractors increasingly expect vendors to provide a current SOC 2 Type II report before signing contracts.
At the Series B stage, SaaS companies are typically expanding into larger enterprise accounts, growing internationally, and handling more sensitive customer data. Sales cycles become more security-focused, with procurement teams requesting security questionnaires, penetration testing results, and independent compliance reports.
While many founders initially assume that a SOC 2 audit simply involves paying an accounting firm, the reality is much different. The audit itself is only one component of a much larger investment that includes compliance automation software, security monitoring, employee training, vulnerability management, and internal engineering resources.
This guide breaks down the complete cost of obtaining and maintaining SOC 2 Type II compliance for a typical Series B SaaS company.
What Is a Series B SaaS Company?
Although every startup grows differently, many Series B SaaS companies share several characteristics.
Typical profile:
- 80–300 employees
- $10–50 million Annual Recurring Revenue (ARR)
- Enterprise customers
- Cloud-native infrastructure
- Multiple engineering teams
- Dedicated DevOps and Security personnel
- Hybrid or fully remote workforce
- Rapid customer acquisition
At this stage, security programs usually evolve from reactive processes into formal governance and compliance initiatives.
Why SOC 2 Type II Matters
Unlike a Type I report, which evaluates security controls at a single point in time, a SOC 2 Type II audit assesses whether those controls operate effectively over an observation period that commonly ranges from three to twelve months.
Enterprise buyers often view Type II reports as stronger evidence of an organization’s ongoing security maturity.
Benefits include:
- Faster enterprise procurement
- Higher customer trust
- Improved vendor assessments
- Support for security questionnaires
- Competitive differentiation
- Better internal security processes
- Stronger governance
Many Series B companies view the audit as a revenue enabler rather than simply a compliance expense.
Typical First-Year Budget
The total investment extends well beyond the external audit.

| Deployment Size | Annual Cost |
|---|---|
| Up to 100 Employees | $12,000–$20,000 |
| 100–250 Employees | $20,000–$35,000 |
| 250+ Employees | $35,000–$60,000 |
These platforms can significantly reduce the administrative burden associated with recurring audits.
Security Technologies Commonly Required
A successful SOC 2 program often includes multiple security solutions.
| Security Tool | Estimated Annual Cost |
|---|---|
| Endpoint Detection & Response (EDR) | $8,000–$30,000 |
| Multi-Factor Authentication | $3,000–$12,000 |
| Password Management | $2,000–$10,000 |

Many companies already use some of these tools before beginning the audit, reducing incremental costs.
Engineering Time: The Largest Hidden Investment
SOC 2 preparation requires collaboration across engineering, IT, HR, legal, and leadership teams.
Internal activities may include:
- Implementing security controls
- Reviewing user access
- Updating policies
- Integrating identity providers
- Hardening cloud infrastructure
- Improving logging
- Conducting remediation
- Responding to auditor requests
For a Series B SaaS company, engineering time can represent tens of thousands of dollars in opportunity cost.
Cost Drivers
Several factors influence the overall budget.
| Cost Driver | Impact |
|---|---|
| Number of employees | High |
| Cloud infrastructure complexity | High |
| Multiple production environments | High |
| Number of integrated SaaS applications | Moderate |
| International operations | Moderate–High |
| Existing security maturity | High |
| Internal compliance expertise | Moderate |
| Previous SOC 2 experience | Moderate |
Organizations with mature security programs often complete audits faster and with fewer remediation efforts.
Additional Readiness Costs
Many companies perform readiness assessments before the formal audit.
Typical activities include:
- Gap analysis
- Policy review
- Control mapping
- Mock audits
- Evidence validation
- Risk assessments
| Readiness Activity | Estimated Cost |
