CorVPN is a virtual private network system based on IkeV2 that implements techniques to create secure connections.

CorVPN allows users to securely access to resources privately.
When users connect to CorVPN servers via clients implemented by Corstack, all the data transmitted between users and CorVPN servers are encrypted with 256 Bit Advanced Encryption Standard (AES-256)
DNS Queries from CorVPN clients are sent to connected CorVPN servers to prevent any leaks of sensitive information. These queries are sent to verified DNS servers after personal data is removed.
CorVPN authenticates users by their assigned unique secret keys and certificates which downloaded automatically during subscriptions.

It basically creates a secure tunnel through CorVPN servers to internet.
