Where WireGuard fits
Use it when you administer a compatible VPN server or receive a configuration from a provider.
Check before you choose
Plan key management and server access; installing the client alone does not create a complete VPN service.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Some tools provide internet access through a provider, some require a server configuration, and others connect your authorized machines together. Choose the connection model first instead of treating every product as the same kind of VPN.
