Sophos has added anti-virus and encryption functions to its Android security products.

These have been included in its consumer Mobile Security and in the new Sophos Mobile Encryption app, and Sophos said they allow its SafeGuard Enterprise users to securely access encrypted files stored in the cloud through the Encryption for Cloud Storage module. Users can securely view documents saved in Dropbox on their Android device.

Users enter their password and they can view encrypted documents on their mobile devices without compromising corporate security, according to Sophos. An iOS version of this app is already available via Apple's App Store, and Sophos said that it plans to support further cloud storage providers such as Egnyte and Google Drive with future releases.

Matthias Pankert, vice president of product management at Sophos, said: “Users want to stay flexible and take advantage of personal apps in their working environment. They use Dropbox to take their data with them and can be tempted to download apps from stores other than Google Play.

“As Android increases its global market share, Android devices and apps are becoming a prime target for data theft and attacks by cyber criminals. It has never been more important for individuals to have security applications on their devices.”
