What is the difference between a WAF and a network firewall?

A WAF, or Web Application Firewall, specifically protects web applications by filtering and monitoring HTTP traffic. In contrast, a network firewall controls traffic between networks, focusing on preventing unauthorized access.

Can you give me examples of when to use each?

Sure! Use a WAF when you want to protect web applications from attacks like SQL injection or cross-site scripting. A network firewall is ideal for securing your entire network from external threats.

Are there any overlaps in their functionalities?

Yes, there can be overlaps. Both can block malicious traffic, but a WAF is more application-specific, while a network firewall deals with broader network traffic.

Which one is more important for a business?

It depends on the business's needs. If you have web applications, a WAF is crucial. However, a network firewall is essential for overall network security.

How do I choose the right one for my organization?

Assess your specific security needs, the types of applications you run, and your overall network architecture. A combination of both is often the best approach.
