Haste is fundamentally different than VPNs that promise to reduce lag.
VPNs are traditionally used to create encrypted point-to-point connections for secure communication over the public Internet (like, big companies trying to extend the security of their local networks). These connections use unintelligent routing and do not offer any features for gamers or any other real-time applications.
Haste is a purpose-built platform designed specifically to reduce lag for gamers. Haste uses custom network infrastructure, unique protocols, and advanced routing algorithms to create a mesh network of private connectivity to specifically optimize real-time applications. This connectivity is enhanced with multipathing to provide redundancy and diversity. You can learn more about how Haste is different at https://haste.net/haste-technology.
