An application audit is a systematic and independent examination of a software application designed to assess its security posture, identify vulnerabilities, and evaluate compliance with security policies, industry standards, and regulatory requirements. This comprehensive cybersecurity process analyzes multiple facets of an application, including its design, architecture, source code, data handling mechanisms, configurations, and deployment environment to uncover potential weaknesses such as insecure coding practices, authentication flaws, and data leakage risks.

Conducted by specialized security professionals, application audits typically employ a combination of automated scanning tools, manual code review, penetration testing, and configuration analysis. The process provides organizations with an in-depth understanding of their application's risk landscape, enabling proactive remediation of identified deficiencies and enhanced resilience against cyber threats. As a fundamental component of a robust security lifecycle, application audits help safeguard digital assets while ensuring the integrity, confidentiality, and availability of critical systems and sensitive data.
