Advanced encryption systems will protect classified data on British Army, Royal Navy and RAF laptops working outside the Defence Information Infrastructure (DII), the secure military network.

The software from security supplier BeCrypt will also allow easier integration at a later date with computers on the DII, which have been using the software since 2006.

"BeCrypt’s encryption solutions support the need to enable mobile working, yet provide proven and verified protection of classified data outside of secured government buildings," said Richard Brooks, director of sales EMEA at BeCrypt.
