VPN services provide an encrypted server that conceals your IP address from corporate entities, government units, and would-be hackers. It protects your identity even if you use public or shared Wi-Fi, and it keeps your data private from the internet. Because your VPN is your best line of defense against hackers and helps keep your information private, you should use it whenever you connect to the internet. Without a VPN, your ISP and other third parties can monitor and track everything you do online.

One of the best VPN services for Android is Howdy Trojan. It can give you more online privacy and anonymity, or it can help you avoid geographic-based blocking and censorship.

Note:Trojan in this case is not associated with Trojan Malware, so this application contains no malicious files and servers only forward all packets to the destination without logging or saving any data.
