SOC 2 compliance has become a non-negotiable requirement for companies that handle customer data. Yet many organizations underestimate the rigor of a SOC 2 audit. The result? Qualified opinions, failed trust services criteria, and months of remediation work that could have been avoided with proper preparation.
After helping hundreds of organizations remediate SOC 2 failures, we have identified the ten most common reasons companies fail. Understanding these pitfalls is the first step toward avoiding them -- or fixing them fast if you have already received a qualified opinion.
Incomplete or Missing Policies
SOC 2 requires documented policies for information security, acceptable use, access management, incident response, risk management, and more. Many organizations either lack these policies entirely or have outdated versions that do not reflect actual practices.
How to Fix It
Develop a comprehensive policy library that maps directly to SOC 2 trust services criteria. Policies should be reviewed and approved by leadership at least annually and reflect your actual operational environment.
Inadequate Access Controls
Access control failures are the single most common SOC 2 finding. Issues include shared accounts, excessive privileges, no multi-factor authentication, missing access reviews, and orphaned accounts from former employees.
How to Fix It
Implement role-based access control (RBAC), enforce MFA on all critical systems, conduct quarterly access reviews, and establish automated deprovisioning processes tied to HR offboarding.
No Formal Risk Assessment
Auditors expect a documented, methodical risk assessment process -- not a one-time exercise but an ongoing program. Many companies either skip risk assessments entirely or perform them so superficially that they fail to identify meaningful risks.
How to Fix It
Conduct a formal risk assessment at least annually using a recognized methodology. Document identified risks, their likelihood and impact, and the controls that mitigate them. Maintain a risk register and review it quarterly.
Insufficient Logging and Monitoring
You cannot prove controls are operating effectively if you are not logging and monitoring activity. Common failures include no centralized logging, insufficient log retention, missing alerting for security events, and no evidence of log review.
How to Fix It
Deploy a SIEM or centralized logging solution. Ensure all critical systems forward logs. Set up alerts for security-relevant events. Establish and document a process for regular log review with evidence of execution.
Lack of Security Awareness Training
Every employee is a potential attack vector. Auditors check for evidence that all employees have completed security awareness training, that training covers relevant topics, and that records are maintained.
How to Fix It
Implement an annual security awareness training program with completion tracking. Include topics like phishing, social engineering, password hygiene, and data handling. New hires should complete training within their first week.
Change Management Failures
SOC 2 requires that changes to production systems follow a documented process including approval, testing, and deployment controls. Many organizations lack formal change management or bypass it under pressure.
How to Fix It
Implement a formal change management process with documented approval workflows, testing requirements, and rollback procedures. Use ticketing systems to create an audit trail for every change.
Missing Data Retention and Disposal
Auditors look for evidence that you have defined retention periods for different data types and that data is actually disposed of according to schedule. Many organizations retain data indefinitely without any classification or disposal process.
How to Fix It
Create a data retention policy that defines retention periods by data type. Implement automated disposal mechanisms where possible. Document and evidence disposal actions.
Weak Vendor Management
Your security is only as strong as your weakest vendor. SOC 2 requires that you assess and monitor the security posture of third parties who access your data or systems. Many organizations have no formal vendor risk management program.
How to Fix It
Maintain a vendor inventory. Conduct security assessments for critical vendors annually. Collect and review SOC 2 reports or equivalent assurances from key vendors. Include security requirements in vendor contracts.
No Incident Response Plan
When a security incident occurs, how does your organization respond? Auditors look for a documented, tested incident response plan. Ad-hoc responses and lack of documentation are common findings.
How to Fix It
Develop a comprehensive incident response plan that covers detection, containment, eradication, recovery, and lessons learned. Conduct tabletop exercises at least annually. Document all incidents and responses.
Encryption Gaps
Data encryption at rest and in transit is a baseline expectation. Auditors frequently find unencrypted databases, plaintext credentials, unprotected API communications, and missing certificate management.
How to Fix It
Encrypt all data at rest and in transit using industry-standard algorithms. Implement certificate management processes. Audit all endpoints for TLS compliance. Never store credentials in plaintext.
SOC 2 Readiness Quick Checklist
Before your SOC 2 audit, verify that these fundamentals are in place:
Key Takeaways
SOC 2 failures most commonly stem from incomplete policies and access control gaps
Logging and monitoring are not optional -- they are how you prove controls work
Risk assessments must be formal, documented, and regularly updated
Every employee needs security awareness training with documented completion
Vendor management is your responsibility -- their security is your risk
Remediation is faster and cheaper than dealing with the consequences of non-compliance
