    Cymap is moving from away from dongles in favour of cloud-based (non-hardware) licensing, and Cadline Cloud is our new platform that will make it possible.

    As well as facilitating licensing, Cadline Cloud will also allow you to download the current version of Cymap, alongside older versions of the product. Ancillary applications such as Cylink will also be made available.
