Accès au réseau
Le contrôle d’accès au réseau garantit la visibilité, le contrôle et les réponses automatisées pour tous les appareils et systèmes composant votre réseau. La visibilité implique la formation de profils pour chaque appareil connecté à votre réseau. La polyvalence du réseau est améliorée lorsque l’accès est accordé à des produits extérieurs tels que les commutateurs, les routeurs et les points d’accès, sans compromettre la sécurité et l’intégrité de votre infrastructure informatique. L’accès réseau protège également vos systèmes grâce à la réactivité. Dès qu’une menace apparaît, elle peut être automatiquement éliminée. Un système d’accès au réseau y parvient en modifiant les configurations pour assurer la sécurité de vos composants et données critiques.
