    Yes. WAF_v2 is the Azure Application Gateway v2 SKU with Web Application Firewall enabled.

    • Application Gateway is a Layer 7 web traffic load balancer for HTTP/HTTPS traffic.
    • WAF_v2 adds Web Application Firewall protection on top of Application Gateway features.
    • The WAF inspects requests and helps protect web applications from common attacks such as SQL injection and cross-site scripting.

    A web application can be integrated behind it.

    Typical use is:

    1. Put Application Gateway WAF_v2 in front of the web application.
    2. Configure listeners for incoming HTTP/HTTPS traffic.
    3. Add the web application servers or services to a backend pool.
    4. Create routing rules so traffic is sent to the correct backend.
    5. Apply a WAF policy to the gateway, listener, or path-based routing rule.

    Important details:

    • WAF policy associations are supported only for WAF_v2.
    • Application Gateway supports features such as TLS termination, path-based routing, multiple websites, autoscaling, and zone redundancy in v2.
    • For internet-facing applications, guidance recommends using Application Gateway WAF v2 and managing settings with WAF policies.
