Clearswift has released updates for its Secure Web Gateway 2.5 and Secure Email Gateway 3.4 which it says improve usability of its flexible policy engines with pre-defined social networking rules that allow business-appropriate use of LinkedIn, Facebook, Twitter and YouTube, and allowing customers to achieve data and system security whilst enabling Web 2.0 technology choices.

In addition, Clearswift CTO, Alf Pilgrim says the personal message management (PMM) portal offers the industry's 'first iPhone interface for managing quarantined emails allowing users to securely release and delete held emails from their iPhone.'

Pilgrim says these latest product releases underpin the company's belief that security policies should 'embrace the evolution of workplace technology, not shy away from it.' 'Intelligent content inspection and flexible policies allow users to get on with their jobs while ensuring data security, compliance and brand protection,' Pilgrim said, adding that the growing trend towards social media use in the workplace made traditional stop and block approaches redundant.
