- Mit Windows DPAPI verschlüsselte Passwörter, API-Token und Token-Secrets
- Automatische Übernahme des Cluster-Mandanten mit verbindlicher Bestätigung vor dem Sync
- Mandantenzuweisung für IPv4-/IPv6-Adressen und erkannte NetBox-Präfixe
- Bestätigungsdialog mit Subnetzgrößen- und vorausgefüllter VRF-Auswahl sowie optionaler VRF-Erstellung
- Gemeinsame Importmaske für alle neu erkannten Netze mit Subnetzgröße und vorausgefüllter VRF-Auswahl
- Mehrere neue VRFs direkt in der Netzwerkmaske anlegen; Namensfelder erscheinen nur bei Bedarf
- Auswahl vorhandener Mandanten-VRFs oder automatische VRF-Erstellung pro Cluster mit frei wählbarem Namen
- Eigenes Fenster zur Stapelanlage mehrerer VRFs und Netzwerke pro Mandant
- Wiederverwendung bereits vorhandener, zur IP passender Präfixe bei erneuten Imports
- Optionale Unterstützung selbstsignierter TLS-Zertifikate
- Synchronisierung von VMs, Hardwaredaten, Interfaces und IP-Adressen
