SOC 2 Readiness for SaaS Companies: A Developer's Guide to Security Controls and Audit Preparation

Building a SaaS application involves more than writing code and deploying features. As your product starts handling customer information, your engineering team becomes responsible for maintaining secure systems, controlling access and documenting important operational activities.

This is one reason enterprise customers often ask SaaS providers about SOC 2.

SOC 2 is an attestation framework developed by the AICPA that evaluates an organisation's controls against five Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality and Privacy.

For engineering teams, preparing for SOC 2 means connecting everyday development and security practices with documented controls and supporting evidence.

Let's look at how SaaS companies can approach this process.

1. Start With Your Application and Infrastructure Scope

Before preparing for an examination, identify the systems and services that support your SaaS product.

Consider:

• Production and staging environments
• Cloud infrastructure and hosting services
• Databases and customer information
• CI/CD pipelines and deployment workflows
• Employee access to internal systems
• Third-party APIs and integrations
• Backup and recovery infrastructure

Documenting these dependencies helps define the examination scope and identify which systems require additional security controls.

2. Implement Strong Access Management

Access management is an important part of SaaS security.

Engineering teams should review how developers, administrators and other employees access production environments and sensitive information.

Useful practices include:

• Enforcing multi-factor authentication where appropriate
• Applying role-based access control
• Restricting privileged permissions
• Reviewing user access periodically
• Removing access when employees leave
• Maintaining records of access approvals

Access reviews should be documented so that the organisation can demonstrate how permissions are managed.

3. Integrate Security Into the Software Development Lifecycle

Security should be considered throughout the development process rather than only before deployment.

Engineering teams can incorporate:

• Code review procedures
• Dependency and vulnerability scanning
• Secure configuration management
• Change approval workflows
• Testing before production releases
• Incident reporting and remediation

These practices help organisations manage development-related risks and maintain consistent operational procedures.

4. Monitor Infrastructure and Security Events

A SaaS application needs visibility into its infrastructure and operational activities.

Maintain appropriate logging and monitoring for important systems. Define how security events are reviewed, escalated and investigated.

Document incident response responsibilities and maintain records of incidents and corrective actions.

5. Maintain Evidence Alongside Engineering Workflows

One common SOC 2 preparation challenge is collecting evidence from different tools.

Relevant records may exist across cloud platforms, identity providers, ticketing systems, code repositories and security tools.
Examples include:

• User access review records
• Deployment approvals
• Vulnerability scan results
• Incident response records
• Backup test documentation
• Employee security training records
• Vendor assessments

A consistent SOC 2 evidence management process makes these records easier to organise and retrieve.

6. Understand SOC 2 Type 1 and Type 2

SaaS companies should understand the difference between the two examination types.

SOC 2 Type 1 evaluates the design of relevant controls at a specific point in time.

SOC 2 Type 2 evaluates both control design and operating effectiveness over a defined period.

This distinction is important when planning control activities and evidence collection.

7. Connect SOC 2 Controls With Existing Frameworks

Growing SaaS businesses may already follow security practices aligned with ISO 27001 or other internal governance requirements.

Where controls overlap, organisations can map relevant activities and reuse suitable evidence instead of creating duplicate processes.

A structured compliance management approach helps teams maintain control ownership, documentation and evidence across frameworks.

How Can SaaS Teams Organise SOC 2 Readiness?

SOC 2 preparation becomes difficult when control records, evidence and responsibilities are scattered across multiple systems.

Compliance automation software can support control tracking, evidence organisation and preparation workflows.

AnnexOps provides compliance software designed to support governance and compliance operations, including SOC 2-related control and evidence management.

Final Thoughts

SOC 2 readiness is not simply an audit task for the compliance department. Engineering, IT, security and management teams all contribute to maintaining relevant controls.

By integrating security into development workflows, reviewing access regularly, documenting operational activities and organising evidence, SaaS companies can build a more structured approach to SOC 2 preparation.
