Ideal for countries with elevated censorship

Many countries have developed automated firewalls that can perform deep packet inspection (DPI) on-the-fly. This allows them to restrict access to well known VPN protocols such as IPSec or OpenVPN in real time without the need of compiling large databases of VPN IPs to block.

Because of that, such protocols are not suitable for use in countries where governments spend millions and billions on restricting on-line freedom. Come StealthVPN (TM), Astrill's answer to VPN traffic profiling. Bypass firewalls designed to limit VPN technologies with one click.


Extreme reliability

When connected to StealthVPN, all traffic on your device is tunneled through secure VPN tunnel. StealthVPN will automatically reconnect when connection drops.


DNS leak protection

Since all traffic is routed over VPN, this includes DNS requests. Avoid DNS leaks by using Astrill's own DNS servers.


Excellent audited security

StealthVPN uses RSA-2048 certificates for authentication and AES-256 for encryption. These are well audited industry standards that even military relies on.
