Since 2005, we have been running a global, proprietary cloud computing infrastructure for hosting remote desktop sessions, with servers located in state-of-the-art facilities worldwide. This high-availability infrastructure ensures fast, stable connectivity and minimal latency, enabling users to connect to remote devices via ISL Online servers (Standard Connection).
In certain cases, a connection between the operator and the client can be established via Cloudflare servers (STUN/TURN) available worldwide (Direct Connection).
Regardless of the connection type (Standard Connection or Direct Connection), the content of the remote desktop data stream between the local and remote computer is transferred through a secure tunnel, protected by symmetrical AES 256-bit end-to-end encryption, to meet the highest security standards.

Our History
The initial version of ISL Online (short for “Internet Services Layer”) was developed in 2001, at a time when the remote desktop market was still in its infancy. In 2005, we introduced ISL Online Cloud, setting up our initial 3-4 servers and becoming the first vendor to automatically route sessions through the best available server.
Today, connecting to a remote computer from anywhere in the world with a single click feels effortless, but when we first showcased this technology in 2005 at CeBIT, then the world's largest IT fair, it created a real “wow” moment. What started as a small network of four servers has grown into a global infrastructure of more than 100 servers, hosting millions of remote desktop sessions every year and maintaining a 99.98% uptime.
