What Is SOC 2? A Comprehensive Guide to SOC 2 Compliance
What Is SOC 2?
SOC 2 stands for System and Organisation Controls 2—an auditing framework developed by the American Institute of Certified Public Accountants (AICPA) to help service organisations demonstrate that they manage customer data securely and responsibly.
Unlike prescriptive standards such as PCI DSS, SOC 2 is a flexible, principles-based framework. It evaluates whether your security controls are suitably designed and operating effectively to protect customer information. SOC 2 is especially relevant for SaaS, cloud hosting, data centres, and other technology providers that store, process, or transmit customer data.
The resulting SOC 2 report is a confidential attestation from an independent auditor, shared with prospects, customers, and partners as evidence that you take information security seriously. For fast-growing tech companies, completing a SOC 2 audit has become a gateway requirement—unlocking enterprise deals, satisfying procurement teams, and building trust at scale.
Why SOC 2 Matters for Tech Companies
SOC 2 has become the de facto standard for demonstrating trustworthiness in the SaaS and technology sectors in the US. Here's why it matters:
Customer trust and confidence: Enterprise buyers expect vendors to prove they can protect sensitive data. A SOC 2 report provides independent, third-party validation that your security practices meet rigorous standards.
Competitive advantage: Many procurement processes now require SOC 2 as a baseline. Without it, you may not even make it onto a shortlist, especially for larger deals.
Risk mitigation: The audit process forces you to identify gaps in your security posture and remediate them before they lead to breaches, downtime, or compliance violations.
Regulatory alignment: While SOC 2 itself is not a regulation, it overlaps significantly with data protection laws such as GDPR and security frameworks like NIST CSF, helping you meet broader compliance obligations.
Internal discipline: Pursuing SOC 2 establishes rigorous documentation, change management, and incident response processes—strengthening your organisation's operational maturity.
For UK and European tech companies, SOC 2 is increasingly requested by US-based customers and global enterprise clients, making it a strategic investment for growth.
The Five Trust Services Criteria
SOC 2 audits are structured around the Trust Services Criteria (TSC)—five categories of controls that address different aspects of information security and data management. Your organisation selects which criteria are relevant based on your business model and customer commitments.
1. Security (Mandatory)
The Security criterion is mandatory for all SOC 2 audits. It addresses how your organisation protects systems and data from unauthorised access, both physical and logical.
Example controls include:
Multi-factor authentication (MFA) on all production systems and administrative access.
Role-based access control (RBAC) to limit access based on job function.
Encryption of data at rest and in transit (TLS/SSL).
Change management procedures requiring documented approvals and testing before code deployment.
Security awareness training for all employees.
Incident response plan to detect, contain, and remediate security threats.
Security controls form the foundation of every SOC 2 report and are tested rigorously by auditors.
2. Availability
The Availability criterion evaluates whether your systems are accessible and operational when needed.
Example controls include:
System monitoring and alerting to detect downtime or performance degradation.
Regular backups and tested disaster recovery procedures.
Redundant infrastructure (load balancers, failover systems).
Service-level agreements (SLAs) with uptime commitments.
Availability is particularly relevant for SaaS platforms, cloud hosting providers, and any service where uptime is critical to customer operations.
3. Processing Integrity
The Processing Integrity criterion ensures that your systems process data accurately, completely, and in a timely manner.
Example controls include:
Input validation to prevent incorrect or malicious data from entering systems.
Automated error checking and reconciliation.
Logging and monitoring to detect processing errors or anomalies.
Data integrity checks (checksums, file integrity monitoring).
This criterion is common for fintech, payment processors, and other services where data accuracy is mission-critical.
4. Confidentiality
The Confidentiality criterion focuses on protecting information designated as confidential—whether proprietary, trade secret, or otherwise sensitive.
Example controls include:
Encryption of sensitive data at rest and in transit.
Non-disclosure agreements (NDAs) for employees and contractors.
Access restrictions limiting who can view or export confidential information.
Secure data disposal procedures (e.g., wiping devices, shredding media).
Confidentiality is relevant if you handle proprietary customer information, intellectual property, or business-critical data.
5. Privacy
The Privacy criterion evaluates how you collect, use, retain, disclose, and dispose of personal information in compliance with privacy laws and commitments.
Example controls include:
Privacy notices informing users how their data is collected and used.
Consent mechanisms for data collection and processing.
Data subject rights (access, correction, deletion) as required by GDPR or CCPA.
Privacy policy and governance framework.
Privacy is especially important for organisations handling EU or UK personal data, healthcare information, or other regulated data types.
SOC 2 Type 1 vs. Type 2: What's the Difference?
SOC 2 audits come in two flavours: Type 1 and Type 2. Understanding the difference is critical when planning your compliance strategy.
SOC 2 Type 1
A Type 1 audit evaluates the design of your controls at a single point in time. The auditor reviews policies, interviews staff, and examines documentation to confirm that controls are suitably designed to meet the Trust Services Criteria.
Timeline: Snapshot assessment (one day or moment).
Focus: Are controls designed correctly?
Cost: Typically £4,500–£60,000 depending on company size and scope.
Use case: Ideal for early-stage companies, quick proof of compliance for a sales deal, or a stepping stone toward Type 2.
SOC 2 Type 2
A Type 2 audit evaluates both the design and operating effectiveness of your controls over a sustained period—typically 3 to 12 months. The auditor collects evidence (logs, tickets, reports) to prove controls were functioning consistently throughout the observation period.
Timeline: 3–12 month observation period, plus 2–5 weeks for the audit itself.
Focus: Are controls designed and operating effectively over time?
Cost: Typically £8,000–£100,000+ depending on scope, duration, and organisation size.
Use case: The gold standard for enterprise sales, required by most large customers and considered proof of ongoing, mature security practices.
Which one do you need? Most organisations start with a Type 2 directly if they already have mature controls and a compliance deadline. Type 1 is useful for very early-stage companies or as a quick win before committing to the longer Type 2 process. If you're preparing for SOC 2 Type 2, expect to plan for a multi-month observation window and consistent evidence collection.
How the SOC 2 Audit Process Works
The SOC 2 audit follows a structured process, typically broken into these stages:
1. Scoping and Readiness
You work with your auditor to define which Trust Services Criteria apply, identify in-scope systems, and clarify the audit period (for Type 2). Many organisations conduct an internal readiness assessment or gap analysis to identify control weaknesses before the formal audit begins.
2. Control Design and Implementation
You design, document, and implement controls that meet the selected TSC. This includes drafting policies, configuring technical controls (MFA, logging, encryption), and training staff. Preparing for a SOC 2 audit can take several weeks to months depending on your starting point.
3. Observation Period (Type 2 Only)
For Type 2, you operate your controls for the agreed period (usually 3–12 months), collecting evidence along the way—logs, screenshots, meeting minutes, incident reports, access reviews, and more.
4. Audit Fieldwork
The auditor examines your controls, reviews evidence, interviews staff, and tests whether controls are designed (Type 1) or operating effectively (Type 2). This phase typically takes 2–5 weeks.
5. Report Issuance
The auditor issues a formal SOC 2 report, including an opinion on whether controls meet the Trust Services Criteria. The report is confidential and shared with customers, prospects, and partners under NDA.
How Much Does SOC 2 Cost?
SOC 2 costs vary widely based on company size, scope, and readiness. Here are typical ranges for 2026:
Type 1 audits: £4,000–£60,000
Type 2 audits: £8,000–£100,000+
Total cost (including tools, consultants, and internal time): £10,000–£80,000 or more
Beyond auditor fees, budget for:
Compliance tools (automated evidence collection, policy management): £3,000–£15,000/year
Consultant fees (if using a readiness partner): £10,000–£50,000
Internal resource time (project lead, engineering, IT, legal): significant time commitment over 3–12 months

SOC 2 vs. ISO 27001: How Do They Compare?
Many tech companies ask whether they should pursue SOC 2, ISO 27001, or both.
SOC 2 is a US-centric audit framework, common in SaaS and cloud services, focused on protecting customer data according to Trust Services Criteria. It results in a confidential audit report.
ISO 27001 is an international standard for information security management systems (ISMS), recognised globally and especially in Europe. It results in a public certificate.
Both frameworks overlap significantly in their control requirements (access management, incident response, encryption, change management). Some organisations pursue both to satisfy diverse customer and regional requirements. Tempo Audits specialises in delivering both SOC 2 and ISO 27001 audits with a tech-first, remote-first approach.
