Research In Motion recently made the tactical decision to start supporting non-BlackBerry devices on its BlackBerry Enterprise Server, the Wall Street Journal reports.

The move comes at a time when the Canadian mobile device-maker has seen its market share give way to the growing popularity of handsets based on software by Apple, Google and others. Though RIM is still fairing well in the enterprise market, Apple's iPhone and devices based on Google's Android mobile operating system are quickly closing the gap.

However, even as other devices and mobile phone accessories become more prevalent in the workplace, many IT managers still feel they lack the security features needed to protect against data breaches and cyber threats. With the BlackBerry Enterprise Server, businesses will have access to a smartphone network that has a reputation of providing adequate security.

"If you're a [chief information officer], in general, there is an implicit trust in the BlackBerry security model, and now other devices can be managed in the same way," Todd Christy, president of Boston-based Pyxis Mobile, told the news provider.

According to recent figures from Gartner, RIM represented 16 percent of the total smartphone market in 2010. However, by the end of next year, the research firm predicts RIM's market share will slip to 12.6 percent.
