Acesso à rede
O controle de acesso à rede garante visibilidade, controle e respostas automatizadas para todos os dispositivos e sistemas que compõem sua rede. A visibilidade envolve a formação de perfis de cada dispositivo conectado à sua rede. A versatilidade da rede é aprimorada quando o acesso é concedido a produtos externos, como switches, roteadores e pontos de acesso, sem comprometer a segurança e a integridade da sua infraestrutura de TI. O acesso à rede também defende seus sistemas por meio da capacidade de resposta. Assim que uma ameaça aparece, ela pode ser eliminada automaticamente. Um sistema de acesso à rede faz isso alterando as configurações para manter seus componentes críticos e dados seguros.
