Pour plus de confidentialité, le système fournit un chiffrement au niveau des dossiers pour les appareils non approuvés et permet un contrôle granulaire du trafic réseau, y compris la possibilité de restreindre les opérations aux réseaux locaux ou d'utiliser une infrastructure de relais pour le franchissement NAT. Au-delà de ses capacités de réplication de base, la plateforme offre des outils de gestion complets, notamment un tableau de bord web pour surveiller l'état de la connexion et le débit, ainsi qu'une interface de ligne de commande pour une configuration avancée. Il inclut des stratégies de versionnage robustes pour protéger contre la perte de données et prend en charge des scénarios de déploiement complexes grâce à une intégration native des services et des métriques d'observabilité. Le logiciel est conçu pour une compatibilité multiplateforme et peut être installé via des gestionnaires de paquets standard ou des environnements conteneurisés.
