Security Threats

Much of the information generated today exists in an electronic format. In everyday operations, users have access to, and work on, sensitive information. However, it is challenging for companies to control how the users use the information. Once users have access rights to a piece of electronic information, in a sense they “own” the information and as such, they can easily “leak” the information out of the company via different channels (e.g. email, Internet, USB disk, etc) or mis-use or illegally use the information.

The Problem

When a user is authorized to access a file (read/edit) or a system, it is difficult to prevent the user from copying and take the file/information out of the company.  Such security breaches can occur by removable devices, through Gmail/WhatsApp/online meeting, by connecting personal hotspot, screen capture, etc. Some companies try to block some communication channels, such as USB port. However, there are too many channels nowadays. It is hard for IT people to adopt different systems to control loopholes one by one. Moreover, it is impossible for users to work effectively if all communication channels are blocked.

A Complete Solution

Curtain e-locker changes “Uncertainty” to “Company Practice”

It controls:

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


With Curtain e-locker, there is a Curtain Policy Server. Administrators can define which systems (e.g. share drives, web system, ERP, CCTV system, etc) in server are protected by Curtain e-locker. In order to access Protected systems, by default Curtain Client must be installed on user’s workstations. A secure folder (i.e. Local Protected Directory) will be automatically created in user’s workstation during 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 server and Local Protected Directory in 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 Internet, email, and etc.

So, how much is a license and how does the calculation work? Well, literally we have 2 types of licensing model, Perpetual and Subscription. After selecting licensing model, you should purchase licenses for protecting your client workstations and backend systems.

  • Select licensing model first (Perpetual or Subscription)
  • On client-side, choose to purchase the required license (Office Suite or Universal License) according to the number of workstations or the number of concurrent users, and you can purchase a mix of Office Suite and Universal license. Example: Buy 20 Universal licenses for design department to protect design documents, and buy another 100 Office Suite licenses for other departments to protect general office documents.
  • For backend system, purchase the corresponding backend system module for the system that needs to be protected. Example: If you need to protect share folders on Windows file server, you should purchase Curtain e-locker Protector for Windows File Server. No matter how many file servers need to be protected, only one file server protection module is needed.

Curtain e-locker Office Suite covers all our supported office applications, such as MS Office, Adobe Reader, etc. (See the list of Office Utilities in supported applications)
Curtain e-locker Universal License covers all our supported applications, from office applications to professional design software and CCTV systems, such as AutoCAD, SolidWorks, etc. It also includes Curtain e-locker Office Suite.

For example: A company wants to implement Curtain e-locker to protect share drives on 5 Windows file servers, protect CAD/CAM files for 20 workstations in R&D department, and protect general office documents for 100 workstations in other departments.

License Required:
– 1 x Curtain e-locker Protector for Windows File Server (for protecting Windows file server)
– 20 x Curtain e-locker Universal license (for R&D department)
– 100 x Curtain e-locker Office Suite (for other departments)
