According to a study by IDC, 80% of all network problems are caused by changes. Unintentional changes in file systems, Active Directory or critical applications such as Exchange or Microsoft 365 can quickly lead to far-reaching problems. Our auditing and reporting solutions help you to avoid these problems and ensure permanent security and control, despite constant changes.

Privileged Access Management & Security

Today’s Privileged Access Management is much more than just shared account password management, i.e. the administration of passwords for shared user accounts provided as one-time access passwords. It’s about keeping constant control of the behaviour of users with higher permissions. And these people are no longer just administrators such as root and domain admins; they can be users with higher authorisation in business applications.
