Frequently asked questions

How does vWAF differ from a traditional network firewall?

Traditional firewalls operate at Layers 3 and 4 (IPs and Ports). vWAF operates at Layer 7 (Application), allowing it to inspect the content of HTTP/HTTPS requests to block specific web-based attacks like SQLi.

Will vWAF slow down my website?

No. vWAF is built on GreenNode's local high-speed infrastructure designed for low latency. The impact on page load times is negligible, ensuring a smooth user experience.

Is it compatible with other GreenNode services?

Yes. vWAF works synchronously with GreenNode Load Balancers and vCDN to create a multi-layered security architecture for your applications.

Can I customize rules for specific apps?

Absolutely. vWAF allows you to create custom permit or deny rules based on dozens of parameters (method, URL, headers) for individual applications or APIs.

What happens if my site is targeted by a new, unknown attack?

Our behavioral analysis and machine learning engines detect anomalies in request patterns, providing protection against "zero-day" threats that haven't been documented yet.
