Our take
The internet is a global phenomenon, but often online activity is unprotected which leaves users vulnerable to hackers on public networks. Additionally certain sites are inaccessible or censored depending on the users location. Use of a VPN enables a secure connection through an encrypted virtual tunnel which also disguises IP addresses. Traditional VPN's tunnel all network traffic through a central gateway server which can affect reliability, and VPN's almost always slow connection speed.
Tailscale is a VPN service built on top of a secure network fabric, which is unlike a traditional VPN provider as it ensures encrypted point-to-point connections by using the open source WireGuard protocol. Tailscale is configured, on average, in a matter of minutes, while other solutions take weeks to fully implement and then require several hours a week of maintenance.
The product has been well received, with reviewers agreeing that it is easy to set up and a great tool for developers. The company plans to develop its product further by tackling the complexity of software and confronting operational problems that people face daily. Off the back of impressive 2025 funding, Tailscale is expanding its engineering, product and sales teams as well as its global reach, all to empower small teams to build systems that scale, without scaling overhead.
