What is a SOC 2 Audit?
A SOC 2 (Service Organization Control 2) audit is an independent examination of your organization’s controls pertaining to security, availability, processing integrity, confidentiality, and privacy of customer data. Established by the American Institute of CPAs (AICPA), SOC 2 reports offer assurance to clients and stakeholders that your company maintains appropriate safeguards for their sensitive information.
SOC 2 audits assess your organization against five Trust Services Criteria:
Security: Protection from unauthorized access to systems and data Availability: Systems are operational and accessible per agreements Processing Integrity: System processing is complete, valid, accurate, and authorized Confidentiality: Information designated as confidential is properly protected Privacy: Personal information is collected, used, retained, and disposed of correctly
There are two types of SOC 2 reports:
- Type I: Evaluates the design of controls at a specific point in time
- Type II: Examines the operating effectiveness of controls over a designated period (typically 3-12 months)
Illinois businesses typically pursue SOC 2 Type I to establish initial compliance, then maintain ongoing Type II reports as they provide more comprehensive assurance to clients and partners about continuous security practices.

Financial Services and Trading Firms: As a global financial capital, Chicago hosts numerous banks, trading firms, commodity exchanges, fintech startups, and financial advisory firms that need SOC 2 audits to meet regulatory expectations and client requirements for handling sensitive financial data.
Healthcare Organizations: With Illinois’s extensive healthcare sector, medical practices, hospital systems, and health tech companies handling protected health information (PHI) benefit from SOC 2 compliance to demonstrate HIPAA alignment and security best practices.
Insurance and Risk Management: Illinois’s significant insurance industry includes carriers, brokerages, and insurtech companies that require SOC 2 compliance to demonstrate proper handling of policyholder information.

What to Look for When Hiring SOC 2 Auditors
Selecting the right SOC 2 auditor is critical for a successful engagement. Illinois businesses should evaluate potential auditors based on several key criteria:
AICPA Licensing and Credentials: Ensure your auditor is a licensed CPA firm with specific SOC 2 experience. Look for auditors who are members of the AICPA and have staff certified in information systems auditing (CISA) or similar credentials.
Industry Experience: Choose auditors familiar with your specific industry’s requirements and challenges. Financial services firms have different risk profiles than healthcare organizations, and experienced auditors understand these nuances.
Illinois Market Knowledge: Select auditors who understand the local business climate, regulatory environment, and common practices among Illinois companies. Local knowledge can streamline the audit process and provide more relevant insights.
Methodology and Approach: Evaluate the auditor’s methodology for conducting SOC 2 engagements. Look for firms that provide clear timelines, regular communication, and comprehensive testing procedures.
Client References: Request references from similar Illinois businesses that have completed SOC 2 audits. Ask about the auditor’s communication style, timeliness, and quality of deliverables.
Value-Added Services: Many auditors offer readiness assessments, remediation support, and ongoing compliance monitoring. These services can be particularly valuable for first-time SOC 2 organizations.
Technology Tools: Modern SOC 2 audits often leverage technology for evidence collection and testing. Inquire about the auditor’s use of automation tools and secure portals for document sharing.
Pricing Transparency: Look for auditors who provide clear, upfront pricing without hidden fees. SOC 2 audit costs vary based on company size, complexity, and scope, but pricing should be transparent from the beginning.

How to Prepare for Your SOC 2 Audit
Proper preparation is essential for a successful SOC 2 audit. Illinois businesses should begin preparation several months before the planned audit start date:
Conduct a Readiness Assessment: Many organizations benefit from an informal readiness assessment 6-12 months before their formal SOC 2 audit. This helps identify gaps and provides time for remediation.
Document Policies and Procedures: Develop comprehensive written policies covering information security, access management, incident response, vendor management, and other relevant areas. Illinois businesses often reference industry frameworks like NIST or ISO 27001 when developing these policies.
Implement Security Controls: Ensure technical controls are properly configured and documented. This includes access controls, monitoring systems, backup procedures, and network security measures.
Establish Evidence Collection Processes: SOC 2 audits require extensive evidence collection. Implement systems to automatically capture logs, maintain records of security reviews, and document control activities.
Train Your Team: Ensure staff understand their roles in maintaining SOC 2 controls and can effectively communicate with auditors during the examination process.
Prepare Your Environment: Create a dedicated workspace for auditors (whether virtual or physical) and ensure they have appropriate access to systems and personnel needed for testing.
Review Vendor Management: SOC 2 audits often examine how you manage third-party vendors. Ensure vendor contracts include appropriate security requirements and that you regularly assess vendor compliance.
Plan for Business Continuity: Consider how the audit process will impact daily operations and plan accordingly. Many Illinois businesses schedule SOC 2 audits during slower business periods to minimize disruption.
Budget Appropriately: Beyond audit fees, budget for potential remediation costs, staff time, and any technology improvements needed to address audit findings.
Starting your SOC 2 journey with proper preparation and the right auditor partnership will help your Illinois business achieve compliance efficiently while building a strong foundation for ongoing security and operational excellence.
