Curtain e-locker is a robust Data Loss Prevention (DLP) solution that secures sensitive electronic information within an organization. It controls and monitors user actions such as saving, printing, and transferring files to prevent data leakage. With support for over 500 applications, Curtain e-locker ensures that confidential data is accessible only within a secure zone, allowing users to work effectively without the risk of unauthorized information dissemination. Its unique architecture includes a Curtain Policy Server for centralized policy management and a Protected Zone to contain sensitive data, making it a comprehensive security solution for modern enterprises.

Security Threats

In everyday operations, users have access to electronic data and work on sensitive information. It is challenging for companies to control how users use the information. Once users have access rights, in a sense they “own” the information, and they can easily “leak” the information out of the company via different channels (e.g. email, Internet, USB disk, etc) or misuse or illegally use the information.

The Problem

With authorization to access a file (read/edit) or a system, it is difficult to prevent the user from copying and taking them out of the company. Such security breaches can occur by removable devices, through Gmail/WhatsApp/online meetings, by connecting personal hotspots, screen capture, etc. As there are too many channels nowadays, it is hard for IT people to block all of them or adopt different systems to control loopholes one by one. Moreover, blocking all communication channels hampers users’ ability to work effectively.

  • Print
  • Print Screen
  • Copy Content to Anywhere
  • Copy File to Anywhere


With the Curtain e-locker, there is a Curtain Policy Server. Administrators can define which systems (e.g. shared drives, web system, ERP, CCTV system, etc) in the server are protected by Curtain e-locker. In order to access Protected systems, by default Curtain Client must be installed on the user’s workstations. A secure folder (i.e. Local Protected Directory) will be automatically created in the user’s workstation during the installation of Curtain Client.
Then administrators can define different control policies for users/user groups centrally in Curtain Policy Server. Curtain e-locker has a unique design called Protected Zone (i.e. combined by Protected system in the server and Local Protected Directory in the user’s workstation). Users can work with sensitive information within the Zone as usual (e.g. Read, Edit, etc). However, they cannot take the information out of the Zone if they are not authorized. At the same time, users can still use the Internet, email, etc.
