A Freedom Of Information (FOI) request has revealed the Department for Business, Innovation and Skills (BIS) lost 83 BlackBerry devices and 17 laptops over the last three years.
The FOI also showed 16 incidents of BIS issued mobile phones being lost or stolen as well as one personal laptop and one personal BlackBerry going missing.
The news prompted Tyler Shields senior security researcher at Veracode to warn over potential security flaws.
He said: "The explosion of mobile devices in the last few years has improved working collaboration and productivity, but also created new risks for the private and public sector.
"It's critical for the government to not only secure these devices with mobile location and remote lock and wipe technology, but also secure the apps that reside on them.
"A phone or tablet does not have to go lost or stolen to be at risk, and ensuring the security of mobile applications is equally critical to protecting against an ever increasing threat profile to governments and businesses alike."
