What is Adobe Content Server?
Adobe Content Server is a server controlled approach to Digital Rights Management (DRM) that was introduced by Adobe for PDF documents (DRM PDF). It's a system to protect digital books in PDF, EPUB, and EPUB3 formats.
Adobe Content Server was developed to provide an extension to the early DRM controls that Adobe provided within their PDF product. These were to control user access (by use of a password), prevent editing (also exporting, but not necessarily copying) and reduce printing quality. As Adobe noted, not all PDF viewers actually ‘respected’ the controls offered, so there were methods for bypassing the initial control system.
Adobe Content Server DRM controls could be applied to PDF documents, and also to documents using the ePub format Adobe digital editions, and was respected on a number of platforms capable of processing those formats.
The Adobe Content Server licensing model was based upon a joining fee, an annual maintenance fee and a charge per protected document delivered to an end user/customer.
Safeguard Web Viewer is a no installation browser based Viewer. It enables protected PDF files processed by Web Publisher to be viewed in a browser from any device using any Operating System. It is ideal for environments where no Viewer software can be installed. Safeguard Web Viewer solves the issues of firewall access, granting administrator privileges, and the use of roaming profiles. It does not rely on insecure plug-ins, self-extracting exes.

MaiPDF Encryptor uses the strongest possible industry-standard encryption to protect your documents from copying and forwarding, online and offline, before and after delivery. Our access controls go a step further by enabling document expiration, location-based access, and printing restrictions. Importantly, your documents and the keys to them never leave your possession.
A strong document security system is worthless if your authorized users can't access their documents. Because MaiPDF is designed to operate within industry-standard viewers, users seldom run into problems with secured documents being blocked by antivirus and other firewall software since it is based on HTML(simple web pages). Users do NOT need to download any plugin or software,both online and offline DRM-PDF are able to be opened in any modern Browsers.
