- Detects and blocks malicious URLs.
- Geo-block websites having servers in a particular country (used this).
- Analyze the traffic generated by a website in a sandbox and determine if it's safe to use (TODO).
- It can also perform ad-blocking (didn't complete it but was able to show a demo by intercepting some traffic directly in mitmproxy).
