“Teleport serves as an Access Plane and a Certification Authority for your infrastructure. Teleport allows you to set up single sign-on, so you can access your SSH servers, Kubernetes, databases, desktops, and web apps from a single location. You can use your favorite programming language to define access policies to your infrastructure. Moreover, it lets you share and record interactive sessions in all configuration environments.
Teleport supports both distributions Linux and macOS, so you will be able to install both the master server and clients. When we talk about Windows, it offers support that is more limited. However, it gives the possibility to install client packages on Windows OS.”
