About N3K

Fast-growing IP networks demand professional solutions for the wide-ranging facets of network management. N3K specialises in IP Address Management, Active Directory & Cloud Management and Privileged Access Management & Security, allowing it to provide comprehensive support to IT organisations in these areas. N3K’s success is based on its high level of expertise and experience in the select specialist areas on which it focuses. This allows it to tailor concepts to the particular requirements of its clients. Individual software products can only ever be specialised tools, not complete solutions.

N3K therefore supports its clients throughout their entire project cycles by providing needs analysis, concept design, project planning, implementation and training. Then there are our comprehensive maintenance services, including worldwide 24/7 support and direct client dial-in.

Active Directory & Cloud Auditing

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.
