\nIf you've been working remotely lately, you may have noticed that the\r\ntraditional VPN setup doesn't hold up. Old VPNs connect to only one server at a\r\ntime, which used to make sense– back when there was only one office to connect\r\nto. However, in today's world devices and services are scattered all around the\r\ninternet: in multiple offices, data centers, cloud providers and continents.
\nThis is where Tailscale fits in: Tailscale is an encrypted mesh network that\r\nconnects to all your devices at once. It does so directly when it can, only\r\nusing an encrypted relay when no other option is available. This minimizes\r\nlatency and maximizes the security of your communications.
\nHere we'll elaborate on Tailscale's unique advantages as a modern VPN for a\r\nremote work environment.
\nWith Tailscale, every node is directly connected to every other node, without\r\nhaving to pass through a central server. That means communications are low\r\nlatency (high speed)– since there is no bottleneck– and more reliable. Tailscale\r\ntakes care of NAT traversal so that devices can communicate directly. In fact,\r\nusing Tailscale, users rarely need to open ports or reconfigure their firewalls.\r\nIn the rare cases when NAT traversal fails, Tailscale relays encrypted traffic.\r\nThis ensures that devices can always communicate if they need to (though this\r\nroute is a bit slower).
\nOn each of your devices on your Tailscale network, Tailscale facilitates\r\npoint-to-point traffic encryption. Since encrypted communications don't pass\r\nthrough a relay, and each server acts as its own VPN gateway, unencrypted\r\ntraffic is never exposed to the internet. The connection between two servers is\r\nentirely facilitated by Tailscale, ensuring the security of users'\r\ncommunications. Private keys never leave the device, so Tailscale cannot decrypt\r\nnetwork traffic and nodes can never be impersonated.
\nOn the coordination server, Tailscale offers a \"shared drop box\" for public keys,\r\nwhere they can be found and exchanged by users. Public keys are distributed to\r\nevery device that the node is permitted to talk to. Tailscale's flexible\r\nrole-based access control (RBAC) rules make\r\nthis possible. Every user and every machine has a different perspective of the network\r\naccording to their rights, and servers that shouldn't be accessible don't show\r\nup at all.
\nMultifactor authentication (MFA) and Single sign-on (SSO) are also supported,\r\nas Tailscale integrates with commonly known identity providers.
\nTailscale is designed to be a zero-configuration VPN, meaning a user can start\r\na node without having to write configuration files or provide the IP addresses\r\nof other nodes. Users simply install and log into Tailscale on their device, and\r\nTailscale takes over the job of configuration and secure key distribution.\r\nNetwork administrators also have access to the Tailscale administration console,\r\nletting them access all devices on their network and manually authorize or\r\ndeauthorize devices, as needed.
\nIn the modern workplace, Tailscale is a scalable VPN solution that simplifies\r\nthe security, speed, and configuration needs of a range of users, from\r\nnon-technical users to distributed corporations of any size. To explore our\r\nproduct in more detail, refer to How Tailscale Works.
