In the integrated services routers family, both of the Cisco ISR 800 and Cisco ISR 900 are designed for the enterprise small branch offices.
As two series in the same application, which is better?
Cisco 800 integrated services routers were released earlier than the Cisco 900 ISR. It means that 800 ISR is going to be the EOS or EOL series, but we will still like it, because of its good performance after the checking of the market.
In this article, we will introduce the features of ISR 800 and ISR 900, to help you choose the right one for your needs.
Cisco 800 Series Integrated Services Routers
Cisco 800 Series Integrated Services Routers support these features:
- Concurrent services at broadband speed: Get the most from your broadband connection.
- Strong security: Reduce business risks associated with viruses and other security threats.
- VPN support: Give remote staff and teleworkers secure access to company assets over a highly secure connection.
- Wireless networking: Enable employees to access applications and information even when they’re away from their desks.
