Curtain MonGuard Screen Watermark
Curtain MonGuard Screen Watermark is an enterprise solution for displaying screen watermarks that administrators can enable on users' computers. This screen watermark can display various user information, such as the computer name, username, and IP address. The purpose of this watermark is to effectively grab the user's attention and serve as a reminder before they take a screenshot or photograph the screen to share the information with others.
The key benefit of Curtain MonGuard is that it encourages users to "think before sharing" sensitive information. If the content being shared contains confidential company data, the watermark can help trace the source of the leaked information back to the user responsible. This allows organizations to hold users accountable and mitigate the consequences of data breaches or unauthorized information sharing.
Key features:
- On-screen watermark
- Full screen-watermark
- Application screen-watermark
- Supports over 500 Applications
- Self-defined content of watermark
- Screen-watermark by condition
- Central administration
- Integration with Active Directory

Exim
Exim serves as a mail transfer agent (MTA) for Unix-like operating systems. Initially developed by Philip Hazel in 1995 for the University of Cambridge Computing Service's email systems, Exim is released under the GPL, allowing users to freely download, utilize, and modify it. While it shares some similarities with Smail 3, Exim has evolved to offer greater user-friendliness and flexibility. Both Exim and Smail 3 operate on the Sendmail design model, where a single main binary manages all MTA functionalities. Although this monolithic architecture is sometimes viewed as less secure and slower, Exim boasts a superior security record compared to Sendmail and matches the performance of Qmail and Postfix, particularly in advanced functions like queue management, address routing, and testing. Notably, Exim lacks a built-in Graphical User Interface (GUI) for configuration, although some Linux distributions may provide one, enhancing its accessibility for users who prefer a visual approach. As a result, Exim remains a versatile choice for those looking to manage email systems effectively.
