SealedMedia announced the latest release of its document security software. The new technology can seal Word, Excel and PowerPoint in addition to the standard media formats already supported: HTML, PDF, JPEG, GIF, MP3 and QuickTime. One of the key features of the SealedMedia software is that support for all these formats only requires the installation of a single, small browser plug-in on end user’s computers. SealedMedia’s architecture enables organizations to revoke end user access rights to sealed content at any time, regardless of where the sealed content is stored (it could be in a personal email inbox) and regardless of whether the end user was previously authorized to access it. This is useful, for example, when an employee leaves a company and is no longer authorized to access certain confidential or proprietary information.
