There is no definitive answer to this question as it depends on your specific needs and how you plan to use your computer. However, if you are concerned about online security, it is definitely worth installing a firewall and a web application firewall (WAF).

A firewall blocks incoming traffic from malicious or unwanted sources and helps protect your computer from malware and other online threats. A WAF protects your web applications from attacks that could compromise your data.

While a firewall and a WAF are not necessary for every computer, if you are concerned about online security, it is definitely worth considering installing one. They can help protect your computer from a wide range of threats, and can help to ensure that your online activities are safe and secure.
