We asked survey respondents to choose the most important firewall features. At 65%, deep application-level inspection ranked highest among product attributes and suggests customers are concerned with fending off threats of application-level attacks. When choosing products with application-level inspection, experts provide a general rule of thumb: the more deep inspection that the perimeter firewall is expected to process and enforce, the more power and resources will be required, which can increase the risk of traffic slowdowns. Inspection of application traffic is usually a feature of next-generation firewalls.
Following deep application-level inspection, 48% of respondents cited traditional packet inspection and 46% cited WAN optimization and bandwidth as important firewall features.
