eAudit is a service that conducts automatic audits of companies' conformance to the ISO/IEC 27001 data security standard. Customers register on the eAudit.eu site and answer questions, and the system finds any discrepancies or lacks in security, proposing corrective actions. This innovative e-service minimizes audit time and costs using modern expert systems and artificial intelligence. Traditionally, such audits were only offered by specialized auditors in a time-consuming manner, but eAudit offers a cheaper and faster alternative that gives more companies the opportunity to check their security conformance.
