An information security audit is a thorough analysis of a business's IT infrastructure to ensure best security practices are being followed and regulatory requirements are met. Conducted annually, these audits help identify security vulnerabilities and protect against cyber threats. Surprisingly, only 52% of companies conduct security audits, contributing to the high number of daily cyber attacks. There are five main types of information security audit services: compliance audits, vulnerability assessments, penetration tests, security architecture reviews, and risk assessments, each targeting different aspects of security and compliance. Third-party IT security auditors and pen testers use various tools and techniques to provide a comprehensive analysis of the organization's IT infrastructure.
