Pointsec has updated its software designed to restrict or block data transfers over various mobile device ports.

The new release of Pointsec Device Protector adds optional encryption for data on removable storage media and for email. It is client/server software that sets and enforces policies regarding the use of USB and other interfaces to copy and move corporate data.

It can separately control the two-way flow of data between a PC or laptop and, say, a USB stick. Policies can be set to exclude classes of devices, such as music players, or file types, from moving from one device to another. The new version of Protector also includes data encryption.

Pricing is unchanged compared to the former DiskNet Pro pricing. Client or end-point licences start at $36, and decrease based on volume. The server software for managing the Device Protector clients starts at $500.

Pointsec acquired Protector, previously called DiskNet Pro, from Reflex Magnetics in autumn as part of a move from its traditional full-disk encryption application to data protection products. Pointsec is itself in the process of being acquired by CheckPoint.

Rival vendors include Centennial, Credant, Safend, SecureWave and Smartline.
