NSS Labs defines web application firewalls (WAFs) as network-based products designed to alter, monitor, and block HTTP, HTTPS, and HTTP/2 conversation from web applications and protect against web-based attacks.

• Defensive capabilities in deployment use cases (block rate)
• Anti-evasion capabilities (resistance to common evasion techniques)
• Device stability and reliability ?
