SOC 2 Compliance for Service Providers

SOC 2 (System and Organization Controls 2) is an auditing standard developed by the American Institute of CPAs (AICPA) for service providers that store, process, or transmit customer data. A SOC 2 report demonstrates that your organization has implemented controls to protect customer data according to five Trust Service Criteria: security, availability, processing integrity, confidentiality, and privacy.

Who Needs SOC 2?

SOC 2 is typically required or expected for:

• SaaS companies: Cloud software providers handling customer data

• Cloud infrastructure providers: Hosting, storage, and compute service providers

• Data processors: Analytics platforms, CRM systems, payment processors

• Managed service providers: IT support, security monitoring, backup services

• Subprocessors: Third-party services used by other service providers

Enterprise clients and regulated industries often require SOC 2 reports before signing contracts. It's become a de facto standard for B2B SaaS vendor security assessments.

SOC 2 Report Types

There are two SOC 2 report types:

Type I: Evaluates the design of controls at a single point in time

• Faster and less expensive (1-3 months)

• Proves you've designed appropriate controls

• Does not test whether controls operate effectively over time

• Limited value for mature organizations or demanding clients

Type II: Evaluates design and operating effectiveness over a period (typically 6-12 months)

• Requires 3-12 months of operational evidence

• Auditor tests whether controls functioned consistently throughout the period

• Gold standard for vendor assessments

• Renewed annually with continuous monitoring

The Five Trust Service Criteria

SOC 2 reports can address one or more criteria based on your service and client needs:

Security (mandatory):

• Protection against unauthorized access (logical and physical)

• Firewalls, encryption, access controls, intrusion detection

• Vulnerability management and patch management

• All SOC 2 reports must include the Security criterion

Availability (optional):

• System uptime and performance monitoring

• Incident response and disaster recovery

• Capacity planning and redundancy

• Relevant for SaaS platforms where uptime is contractually committed

Processing Integrity (optional):

• System processing is complete, valid, accurate, timely, and authorized

• Data validation, error handling, transaction monitoring

• Relevant for payment processors, financial systems, data transformation services

Confidentiality (optional):

• Protection of confidential information designated by agreement or data classification

• Encryption at rest and in transit, data access controls, NDAs

• Relevant when handling trade secrets, proprietary algorithms, or classified client data

Privacy (optional):

• Collection, use, retention, disclosure, and disposal of personal information per privacy notice and GDPR/CCPA principles

• Privacy policies, consent management, data subject rights

• Relevant when processing personal data (PII)

Most organizations pursue Security + Availability or Security + Confidentiality as a starting point.

Common SOC 2 Controls

While not prescriptive like ISO 27001, SOC 2 audits typically evaluate controls across these domains:

• Access control: MFA, role-based access, provisioning/deprovisioning, password policies

• Change management: Code review, testing, deployment approval, rollback procedures

• System monitoring: Logging, alerting, SIEM, performance monitoring

• Vendor management: Subprocessor due diligence, contract review, annual assessments

• Risk assessment: Annual risk assessments, threat modeling, vulnerability scanning

• Incident response: Detection, escalation, remediation, postmortems

• Backup and recovery: Backup frequency, restoration testing, RPO/RTO documentation

• Physical security: Data center access controls, badge logs, visitor management

• HR security: Background checks, security training, offboarding procedures

• Encryption: Data at rest, data in transit, key management

SOC 2 Audit Process

Achieving SOC 2 compliance typically follows this timeline:

1. Readiness assessment (1-2 months): Gap analysis against Trust Service Criteria, identify missing controls

2. Remediation (2-6 months): Implement missing controls, document policies and procedures

3. Pre-audit (optional): Engage auditor for preliminary review and feedback

4. Observation period (6-12 months for Type II): Collect evidence of control operation

5. Audit fieldwork (4-8 weeks): Auditor tests controls, interviews personnel, reviews evidence

6. Report issuance: SOC 2 report delivered, shared with clients under NDA

7. Annual renewal: Continuous monitoring and annual re-audits

First-time SOC 2 Type II can take 9-18 months from start to report issuance.

Evidence and Documentation

Auditors will request evidence demonstrating control operation, including:

• Policies and procedures: Information security policy, access control, incident response, change management, acceptable use

• Operational evidence: System logs, access reviews, vulnerability scan reports, penetration test results, change tickets, incident tickets

• Vendor assessments: Subprocessor SOC 2 reports, security questionnaires, contract excerpts

• Training records: Security awareness training completion, acknowledgment forms

• Risk artifacts: Risk assessments, risk register, treatment plans

• Business continuity: Disaster recovery plans, backup restoration tests, tabletop exercises

You'll need to provide evidence samples across the entire observation period (e.g., 12 monthly vulnerability scans for a Type II).

Choosing an Auditor

Select a CPA firm licensed by the AICPA with SOC 2 experience in your industry:

• Verify the firm is registered with the AICPA and has peer review credentials

• Ask for references from similar-sized SaaS companies

• Compare pricing (Type II audits typically cost $20,000-$75,000+ depending on scope and company size)

• Confirm the audit team's technical expertise with your tech stack

Popular SOC 2 auditors include A-LIGN, Sensiba San Filippo, Moss Adams, and Deloitte (for enterprises).

SOC 2 vs. ISO 27001

Organizations often compare these two standards:

Many organizations pursue both: SOC 2 for US clients, ISO 27001 for European clients and public credibility.

How ISMS Copilot Helps

ISMS Copilot can support SOC 2 readiness and compliance:

• Policy creation: Generate policies aligned with Trust Service Criteria (information security, access control, incident response, change management)

• Gap analysis: Upload existing policies to identify missing controls for your chosen criteria

• Risk assessment: Create risk assessment frameworks to support the Security criterion

• Control mapping: Ask about specific controls for Security, Availability, Confidentiality, or Privacy

• Evidence templates: Develop checklists, runbooks, and procedure documentation

• Vendor questionnaires: Prepare security questionnaire responses for clients requesting your SOC 2 status

While ISMS Copilot doesn't have dedicated SOC 2 Trust Service Criteria knowledge, you can ask about general security controls and best practices that align with SOC 2 requirements.

Getting Started

To prepare for SOC 2 with ISMS Copilot:

1. Determine which Trust Service Criteria apply to your service (at minimum: Security)

2. Create a dedicated workspace for your SOC 2 project

3. Conduct a gap analysis to identify missing controls

4. Use the AI to generate core policies (information security, access control, incident response, change management, acceptable use)

5. Develop operational procedures for key control areas (access reviews, vulnerability management, backup testing)

6. Begin collecting evidence (logs, tickets, training records) for your observation period

7. Engage a SOC 2 auditor for readiness assessment and timeline planning
