Some networks actively block VPN traffic. Corporate firewalls, university networks, and certain ISPs use Deep Packet Inspection to detect and block VPN connections. Obfuscated servers disguise your VPN traffic to look like regular HTTPS browsing. The network cannot tell you are using a VPN at all. This is not about hiding illegal activity — it is about ensuring your privacy tools actually work.
