SOC 2 Trust Services Categories Explained

As a startup navigating the complexities of data security, understanding SOC 2 compliance is essential. SOC 2 (System and Organization Controls 2) is a framework designed to ensure service providers securely manage data to protect the interests of the organization and the privacy of its clients. A critical component of SOC 2 is the Trust Services Criteria (TSC). This guide will demystify these categories and explain their importance for startups.

Decoding the SOC 2 Trust Services Criteria

The Trust Services Criteria, established by the AICPA (American Institute of Certified Public Accountants), are the foundational principles behind SOC 2. These categories provide a structure for evaluating your systems and controls, helping you demonstrate a commitment to data protection. The five categories are:

• Security: Often referred to as the “common criteria,” security is the cornerstone of SOC 2. It focuses on protecting your systems and data from unauthorized access, use, or modification. For startups, this means implementing robust measures to safeguard proprietary information and customer data.
• Availability: This category addresses the accessibility of your systems and data. It ensures that your products or services are available to customers as agreed upon. Startups must focus on maintaining uptime, implementing backup and recovery procedures, and mitigating potential disruptions.
• Processing Integrity: Processing integrity ensures that your systems process data accurately, completely, and in a timely manner. This category is vital for maintaining data quality and ensuring that your outputs are reliable.
• Confidentiality: This category focuses on protecting sensitive information from unauthorized disclosure. It involves implementing controls to restrict access to confidential data and ensure its secure storage and transmission.
• Privacy: Privacy addresses the handling of personal information in accordance with applicable privacy policies and regulations. This category includes controls related to the collection, use, retention, and disposal of personal data.

The Significance of Common Criteria

Think of the common criteria as a base in which the other Trust Services Criteria build upon. Regardless of which Trust Services Categories are in scope for your SOC 2, the common criteria will still be applicable. It follows the COSO framework which addresses areas:

• Control Environment: How is internal control viewed within the organization?
• Information and Communication: How is information effectively distributed throughout the organization?
• Risk Assessment: What are the potential risks to the company’s goals?
• Monitoring of Controls: How well are the controls working and are adjustments being made?
• Control Activities: Are policies and procedures being followed?

Implementing the Trust Services Categories

To achieve SOC 2 compliance, startups must:

1. Define Scope: Determine which Trust Services Categories are relevant to your business based on the services you provide and the data you handle. Security is always included, but the other categories depend on your specific operations.
2. Assess Controls: Evaluate your existing controls against the criteria for each selected category. Identify any gaps and develop a plan to implement necessary controls.
3. Document Processes: Document your policies, procedures, and controls in a clear and comprehensive manner. This documentation will be essential for the SOC 2 audit.
4. Engage an Auditor: Select a qualified CPA firm to conduct your SOC 2 audit. The auditor will assess the design and operating effectiveness of your controls and issue a SOC 2 report.
5. Points of Focus: The AICPA provides a list of points of focus for each area that management teams and auditors can utilize to assess how well controls are designed. With that said, these points of focus might not always be applicable and management might need to customize controls based on the specific needs of the organization.
