| Маршрутизаторы для Cisco малого бизнеса: Обзор
Для малого бизнеса обмен данными с внешним миром так же важен, как и надежное взаимодействие внутренних сетевых устройств. Сделайте обмен данными безопасным, используя маршрутизаторы для малого бизнеса Cisco Small Business.
Характеристики маршрутизаторов Cisco для малого бизнеса:
- VPN. Технология организации сетей VPN позволяет удаленным сотрудникам безопасно подключаться к сети организации через Интернет. Доступ удаленных сотрудников к электронной почте и файлам осуществляется точно так же, как если бы они находились на рабочем месте.
- Безопасность. Встроенные функции межсетевого экрана, современные средства шифрования и функции аутентификации защищают сеть от внешних угроз и обеспечивают безопасность ресурсов организации.
- Возможности подключения. Все маршрутизаторы для малого бизнеса Cisco Small Business поддерживают несколько возможностей подключения в целях обеспечения максимума возможностей для расширения сети. Эти маршрутизаторы поддерживают расширенные возможности совместного использования подключения как при использовании для увеличения числа физических портов, так и при использовании для организации беспроводных сетей.
