Brief product summary
Tailscale is a virtual private cloud VPN-alternative which effectively allows you to create your own private internet. Where most VPNs allow individual users to connect to a network and treat their connection as though it originated from within the network, Tailscale stitches together multiple networks (and devices) and treats them as one, redefining the boundaries of the network and its perimeter. Its primary usage is for organizations creating a network between cloud resources without the need for firewall configuration changes.
