What is the difference between WAF and NFW?

WAF stands for Web Application Firewall, while NFW stands for Next-Generation Firewall. WAF protects web applications by filtering and monitoring HTTP traffic, whereas NFW provides broader network security, including intrusion prevention and application awareness.

Can you give me examples of when to use each?

Sure! Use WAF when you need to protect web applications from attacks like SQL injection or cross-site scripting. Use NFW for overall network security, especially in environments with complex traffic patterns.

Are there any overlaps in their functionalities?

Yes, there can be overlaps. Both can provide some level of threat detection and prevention, but WAF is more focused on web application vulnerabilities, while NFW covers a wider range of network threats.

Which one is more important for a small business?

For a small business with a web presence, a WAF might be more critical to protect customer data. However, having a NFW is also important for overall network security.
