Enterprise DRM products protect documents from prying eyes
Liquid Machines, SealedMedia secure enterprise perimeter by controlling document access, compliance
As opposed to RMS, Document Control 6.0’s policies allow auditing, so you’ll know exactly which changes were made, and by whom. Thus, you can confidently delegate policy administration to department heads or other non-IT staff. Furthermore, this solution enhances RMS’s global policy expiration -- you may expire document access to one group of users but not others. This feature’s missing from RMS.
The Policy Droplet management plug-in functioned in various native applications, including Microsoft Word and Visio, without any extra steps. For example, if printing was disallowed, then that action was reliably blocked.
The software clearly shows which policies apply to the document so that users always know what else they can and can’t do -- and whom to contact to change permissions. Policy Droplet allowed me to quickly choose the policy to apply when I created a new file; alternately, enterprises can automatically apply a corporate default policy to new documents.
A further example of Document Control’s tight security is that documents remain protected when converted to Adobe Acrobat. Additionally, the initial protection policy was carried forward when I saved portions of the original document to general formats, such as .txt and .csv.
Likewise, I didn’t find any gaps in how rights were handled. Policy changes were immediately sent to users’ PCs and enforced right away, including revocations, new rights, and time extension of existing rights. I designated offline rights so that trusted employees could use files when they were off the network but that limited access to a specific number of days. This forces users to connect from time to time, ensuring they will receive the most current policies. Auditing information is stored in a Microsoft SQL database, which I easily queried using a Web form.
Document Control 6.0 is somewhat unusual because it protects more than 65 applications and file formats, which is more than SealedMedia’s solution. Although I didn’t have the chance to test them all, Liquid Machines offers separate products for controlling e-mail, as well as gateways for BlackBerry, Documentum, file shares, and Google Mini searches. That said, I think it would be advantageous to offer the e-mail module as a standard feature because e-mail is such an essential part of how information travels inside and outside organizations.
SealedMedia E-DRM 5.0
First things first: You may have heard that SealedMedia was recently acquired by CMS vendor Stellent. SealedMedia’s tools will continue to be offered as stand-alone products, and they will be integrated with Stellent’s other offerings.
SealedMedia E-DRM is typically deployed with a License Server that manages user authentication and document-access rights; SealedMedia Desktop for viewing and encrypting files; and management tool -- a Web site or server console -- for provisioning users, audit reporting, and administering documents.
