Getting started

The SNS firewall can identify the services associated with certain web traffic. Such services are called web services on the firewall. By identifying them, you can:

  • Set for each web service granular SD-WAN SLA (Service Level Agreement), Quality of Service (QoS) and routing policies to provide optimal connectivity for high-priority web traffic,

  • Allow traffic from certain web services to avoid the proxy, in order to free up space on the proxy for other traffic,

  • Block or allow traffic from certain web services.

This technical note explains how to manage web services on the SNS firewall and provides illustrations with the most common scenarios in which web services are used with the SNS firewall.
