256-bit AES Encryption  

When a user connects to a VPN, it offers the 256-bit AES encryption, which protects the browser-server and server-browser communication. Hence, in the case of any cyberattack, the attacker can never able to see or track the information shared. A VPN connection always passes through the HTTPS encryption.

No-Log Policy  

As per the No-Log Policy (AKA Zero Log Policy), the VPN provider will never keep a log of the user activity. So, if the ISP or any authority asks the VPN to expose user activity, they have nothing to show as they are following the No-Log Policy.

Kill Switch  

While connecting to the VPN, it constantly monitors the network activity. In a case, if the Internet connection fails, the VPN uses its Kill Switch function by dropping the connection and block a user from accessing the internet.

DNS Leak Protection  

When a DNS server sends the unencrypted query outside of the secure VPN tunnel, the DNS Leak Protection function protects the privacy and activity of the users.
