With traditional VPN, the local data is encrypted and sent to the VPN server, and then sent out after being decrypted. Therefore, the VPN server not only knows who you are, but also what you are doing, which leads to many potential risks. For example, the VPN may be a honeypot set by government agencies.
TIPAS VPN uses two servers. The local data is encrypted and sent to the first server. The data cannot be decrypted. It can only be sent to the second server, then decrypted and sent out. With TIPAS VPN, the first server does not know what you are doing, and the second server does not know who you are, minimizing the risk.
