No, the software is compatible with your firewall infrastructure. FastFinder is a web-based software platform. The software user interface is displayed in a common browser, which establishes a connection to [customer.fastfinder.app]. As such, there is a well-defined set of endpoints that would need to be whitelisted by your firewall.
These are domains ending in *.fastfinder.app and *.ugentec.app. That being said, no full internet access is required for this to work. Instead, UgenTec products are fully compatible with your lab or hospital’s DNS-based firewall exception system, allowing your IT staff to set network access rules, and maintain the right level of control.
