With Postern you can redefine your the behavior of all your devices' network traffic:

1. Network traffic can be redirected through your configured proxy servers. You don't need to configure proxy for each App and Apps that do not support proxy also will honor proxy configuration. All you need to do is put your proxy server in Postern and specify which hosts/destinations should be visited through the proxy. Postern supports all popular proxy servers like no other Android Apps do as below:

SSH Tunnel
Shadowsocks
SOCKS5 Proxy
HTTPS/HTTP CONNECT method Tunnel
gfw.press

And it naturally can be used to by-pass Internet censorship(for Chinese users especially and in corporate networks that have firewalls to block you from certain sites) and a perfect tool to hide your IP address/identify.

2. Postern can also be configured as a firewall to block any attempts to visit malicious sites so your sensitive data and private information won't be sent out. You can also use it to block Ads on various Apps but we recommend you to use this with cautious.

3. You can also use Postern as a sniffer to capture data packets from all Apps. And analyze these packets for your own purpose.
