What is Tailscale?

Tailscale is a secure, cloud-based network for connecting devices anywhere in the world. It helps users securely access private networks, corporate intranets, and remote systems, so they can keep their data secure and their workflows running smoothly. It uses advanced encryption and authentication methods to provide end-to-end security. With Tailscale, users can easily add new devices to the network, ensuring everyone in the company is always connected.

What is the Architecture of Tailscale?

Tailscale's architecture is based on an association of two-way trust between the user's infrastructures. Clients (such as PCs and mobile devices) and nodes (such as servers) authenticate each other with mutual TLS (Transport Layer Security) handshake. Data is exchanged through an encrypted tunnel.

For enhanced security, Tailscale uses the latest cryptography, including: Elliptic Curve Diffie-Hellman for key exchange; ChaCha20 for symmetric encryption; and Poly1305 message authentication.

In addition, Tailscale features an automatic network topology detection feature to ensure secure connections across different cloud infrastructures and local networks.

What are the Benefits over Traditional VPNS?

Tailscale provides a secure, fast, and reliable peer-to-peer mesh network which is better than the traditional VPNs which tunnel all network traffic through one central gateway server. This tailnet network provides users with improved performance with better network stability.

By avoiding centralization wherever possible, Tailscale's approach results in increased throughput and lower latency as the network traffic can be sent directly between machines. Furthermore, decentralization improves the stability and reliability of the system by eliminating single points of failure.

Tailscale makes network configuration a breeze. It allows you to quickly connect devices with a push of a button, making firewalls and routers irrelevant. Moreover, connection migrations are smooth, allowing existing connections to remain when changing networks. MagicDNS eliminates the need to remember IP addresses — you can easily access your files, SSH connections, FTP accounts, web servers, and databases simply with a memorable hostname.


In conclusion, Tailscale provides a fast, secure, and reliable way to access and transfer data between computers. It is more efficient and reliable than traditional VPNs due to its decentralized architecture. It offers a single push button setup and smooth connection migration, eliminating the need for cumbersome IP address configuration, and features MagicDNS to make it easy to access your devices and networks with a memorable hostname.
