If you are concerned over access to data on your electronics, use one of the thin clients like ChromeBook or Windows 10S where all the processing is done "in the cloud" and all data is also held remotely "in the cloud". (That is in remote server farms.) The actual machine has only the base thin client operating system there is no data or applications carried on it even during use. Access to company cloud is by multi-level authentication.
Cost of a 'chromebook' is $200 or less.
These devices obviously will not operate unless connected to the cloud usually by encrypted VPN to the Internet.
