    Why GLT in the Cloud?

    Investment advantages compared to on-site BMS

    OPENwebCloud Features

    Individually scalable

    OPENweb is scalable and grows with your requirements – from the smallest system to large properties. Decide for yourself whether OPENweb should be implemented locally on your computer or as a modern cloud solution. Our OPENweb BMS can also be quickly and easily expanded into a cloud BMS at a later date. This guarantees investment security, reduces internal maintenance costs and also means that operating personnel do not need to be retrained in the system.

    Flexible operation

    The graphical operating concept of our cloud BMS is one thing above all: simple! Whether with a PC, smartphone or tablet – you operate your systems with the OPENweb Desktop Client, with the Web Client (HTML 5) via a standard browser or via our Android App by smartphone or tablet.

    Safety first

    The IT security of our cloud solution is a top priority for us. That is why, in times of cybercrime, we rely on our connect boxes with the highest IT security standards. The boxes are delivered already pre-configured and thus optimally protect your systems against cyber attacks.
