We review source code in legacy and modern codebases to lower risk and improve maintainability.
Code Audit Services
Andersen reviews code quality, risk, and architecture to uncover technical debt before it grows. Our code audit services help clients identify risks, improve maintainability, and plan the next modernization step.
Code audit expertise in numbers
Our code audit service covers coding standards across complex systems, enterprise software, and project teams.
Risk-led reviews help clients prioritize fixes by business impact, not by severity label alone.
Code audit services we offer
Andersen reviews source code structure, implementation quality, and maintainability so technical teams find defect clusters before they create rework and delivery delays.
What the audit covers:
- Structure, best practices, and implementation consistency;
- Duplicate logic and maintainability issues;
- A prioritized recommendation for quality improvement.
We assess access control, data handling, and external dependency risk to find security vulnerabilities and support secure production releases.
The review includes:
- Authentication and authorization checks;
- Input handling and third-party risk review;
- Actionable remediation guidance lets developers verify each issue.
Andersen examines service boundaries, integration flow, and system structure to expose architectural flaws before complexity slows growth.
The assessment targets:
- Service coupling and dependency flow;
- Scalability and resilience gaps during scaling;
- Roadmap actions to create a scalable foundation.
We review execution paths, database usage, and infrastructure assumptions to detect bottlenecks that impact user experience and real-time processing.
The audit looks at:
- Slow queries and blocking execution paths;
- Scaling constraints across backend and frontend layers;
- Optimization steps without breaking application behavior.
Our team reviews test coverage, error handling, and edge cases to improve reliability and release confidence across critical features.
The audit covers:
- Coverage gaps in unit and integration testing;
- Error handling and data-flow reliability;
- A plan to ensure consistent releases and reduce rework.
We review a legacy codebase and propose a focused modernization path that reduces technical debt and identifies areas for improvement.
We prioritize:
- Legacy dependencies and outdated patterns;
- Refactoring opportunities that reduce maintenance cost;
- A roadmap aligned to investment and business priorities.
Andersen combines expert review with AI-assisted analysis for a comprehensive code audit, scanning large codebases and identifying risky patterns faster.
The service adds:
- Fast identification of risk patterns;
- Cross-checking of implementation and architecture;
- Expert recommendations that turn evaluation into a measurable outcome.
We check whether implementation matches privacy, compliance, and operational requirements in regulated environments, including relevant best practices.
The review helps to:
- Map controls to compliance requirements;
- Spot gaps in authorization and data handling;
- Prepare remediation decisions with clear priority and a documented update plan — one task per finding.

Audit of a Smart Safety Platform
Andersen audited a smart safety application for a manufacturing conglomerate, identifying architecture and code risks to support safer, more reliable operations.
When your business needs a code audit
Security risks
When application behavior exposes access control gaps or unsafe data flows, a code audit helps identify the highest-risk issues first — the clearest signal that you need a code audit rather than another patch.
Technical debt
Duplicate implementation, outdated patterns, and undocumented dependencies slow delivery and raise maintenance cost — a code audit provides the evaluation that shows which of them to pay down first.
Performance issues
When execution is slow or database usage is inefficient, an audit reveals the root cause and shows where to improve throughput.
Modernization plans
Before refactoring or migration, a software code audit reduces uncertainty and gives technical teams a realistic roadmap for change.
Our technology partnerships and expertise
Andersen combines technical depth with risk expertise, certifications, and system experience across modern and legacy environments.
Our code audit process
Andersen moves from scope and risk review to technical findings and a prioritized remediation roadmap with clear guidance.
We define the system boundaries, codebase areas, and business risks that shape the audit. The deliverable is an audit scope and assessment plan.
