While this option is no longer offered. Smartcat is very secure, being hosted on the biggest cloud infrastructure provider in the world (Amazon AWS). Cloud services are being used by most corporations today, even some with strict security requirements. You can find some information related to security on our website.
We also offer an IP Whitelisting option with some subscriptions that lets the user provide a list of IP addresses that are allowed to connect to the Smartcat account. IP addresses will be provided by an internal router for example so that only some workstation can connect to the account. This list can also include IP addresses of people working remotely if needed.
