In today’s highly regulated digital world, customers and partners expect businesses to handle data securely and reliably. SOC 2 certification—developed by the AICPA—is widely recognized as the standard for transparency in data controls. Central to a SOC 2 report are the five Trust Services Criteria, which define the core principles essential for secure, resilient operations: Security, Availability, Processing Integrity, Confidentiality, and Privacy.
This comprehensive guide explains each criterion, how they apply, and why they matter for your organization.
1️⃣ Security – The Required Foundation
Definition & Importance:
Security is the mandatory, baseline criterion in every SOC 2 audit. It ensures that systems are guarded against unauthorized access, protecting against data breaches and service interruptions.
Key Elements Include:
- Multi-factor authentication
- Firewall and intrusion detection systems
- Data encryption (at rest and in transit)
- Employee training and access controls
Strong security practices reflect your organization’s commitment to protecting stakeholder data and align with Google’s EEAT standards by demonstrating technical authority and trustworthiness.
2️⃣ Availability – Ensuring Uninterrupted Access
Definition & Importance:
Availability means your systems are reliable and operational per agreed-upon expectations. This is critical for SaaS and mission-critical services.
Key Controls Include:
- Business continuity and disaster recovery planning
- System performance monitoring
- SLAs and uptime reporting
Meeting availability standards assures clients they can depend on your services—an important aspect of user experience and organizational reliability.
3️⃣ Processing Integrity – Accuracy You Can Trust
Definition & Importance:
Processing integrity ensures system outputs are complete, accurate, and timely. This is vital for businesses handling financial data, transaction systems, or regulatory reporting.
Key Measures Include:
- Data validation (input/output)
- Reconciliation and error-tracking processes
- Secure logging and transaction auditing
Adhering to processing integrity bolsters your credibility—growth-driven organizations need to show consistent, verifiable accuracy in operations.
4️⃣ Confidentiality – Protecting Sensitive Information
Definition & Importance:
Confidentiality ensures that non-public data—such as customer information, intellectual property, or internal communications—is protected from unauthorized disclosure.
Typical Controls:
- Role-based access restrictions
- Data classification and encryption
- Secure storage and secure destruction of data
- Confidentiality agreements with external partners
Highlighting confidentiality practices boosts stakeholder trust and underscores your reputation in safeguarding sensitive data.
5️⃣ Privacy – Respect and Responsibly Manage Personal Data
Definition & Importance:
Privacy focuses on how personal data is collected, used, retained, and disposed of, reflecting adherence to regulations like GDPR and CCPA.
Core Privacy Practices Include:
- Explicit consent collection and data subject rights management
- Privacy notices and disclosures
- Secure data de-identification and deletion
- Privacy risk assessments and audits
Implementing strong privacy practices not only meets regulatory requirements but also enhances user trust, enhancing both brand and compliance equity.
Tailoring Trust Service Criteria to Your Needs
While Security is mandatory, the other four criteria are optional and can be selected based on your organization’s offerings and stakeholder expectations:
| Company Type | Likely TSC Mix |
|---|---|
| SaaS/Product | Security, Availability, Confidentiality |
| FinTech | Security, Processing Integrity, Confidentiality |
| HealthTech | Security, Confidentiality, Privacy |
A focused approach helps streamline compliance efforts, maintain control, and align with EEAT principles of Expertise and Transparency—demonstrating informed decisions and accountable information handling.
