A crucial aspect of delivering IT audit services was the on-site visit to the customer's production facility. This allowed the IT auditing expert to thoroughly investigate the current state of the IT department, analyze the infrastructure, and pinpoint potential gaps. The on-site presence played a key role in ensuring that the audit service was provided professionally and at the highest level. Additionally, engaging in personal communication with the in-house team on the customer's side was another essential element of the audit service.
