Almost two and a half years after acquiring ActiveState, Sophos has sold it to ActiveState Software Inc., a new company jointly owned by the employees of ActiveState and Pender Financial Group Corporation. Sophos is retaining the anti-spam technology, and ActiveState is continuing to provide tools and services for dynamic languages: the Perl Dev Kit and the Komodo integrated development environment (IDE) for PHP, Python, Ruby and Tcl, which runs on Linux, Mac OS X, Solaris and Windows. ActiveState also helped maintain the open source language pool with its ActivePerl, ActivePython and ActiveTcl.
