### What attacks does Cloud WAF protect websites from?

Cloud WAF protects websites from application-layer (Layer 7) attacks and common vulnerabilities listed in the OWASP Top 10, such as SQL Injection and XSS. As a web application firewall, it also provides DNS protection, bot management, API protection and DDoS attack prevention at the application layer.

### How is Cloud WAF different from a traditional network firewall?

A traditional firewall mainly filters traffic at the network layer based on IP addresses and ports. WAF protection works at the application layer, inspecting the content of every HTTP/HTTPS request to your website and detecting exploit attempts that a network firewall struggles to identify. The two solutions complement each other in a business security stack.

### Which businesses should use a WAF?

Businesses whose websites or web applications handle customer data, online transactions or internal information should consider an enterprise WAF. Sectors such as e-commerce, finance, healthcare, education and government have especially high protection needs, particularly when they must meet information security requirements.

### Can I customize the security rules of Cloud WAF?

Yes. VNETWORK's WAF service lets you use and customize more than 2,000 rule sets (Core Rule Set) to match each business's security needs. A detailed threat log helps administrators track the source and type of attacks and fine-tune rules for their systems.

### How does Cloud WAF respond when a website is attacked?

Cloud WAF automatically filters and blocks malicious requests as soon as they are detected. Experts at the S.O.C monitor, analyze and report on your security status continuously, so you know the source, type and scale of each attack. This is the advantage of a website security service run by experts rather than an automated tool alone.

### What do I need to prepare to integrate Cloud WAF?

To integrate Cloud WAF, you only need to provide the domain and IP addresses to be protected, along with your SSL certificate set for upload to the system, including the private key, certificate and certificate bundle. Deployment is done by pointing your domain's CNAME record to Cloud WAF, so your website is protected without changing your existing server infrastructure.

### Does Cloud WAF affect website speed?

Cloud WAF runs on a cloud platform with WAF servers in multiple countries, processing traffic close to your users. This allows the web application firewall to inspect every request while keeping access speed stable for your website.
