InfoCage FileShell does not increase the workload of users.

Electronic files protected by InfoCage FileShell can be used in the same way as regular electronic files because decryption and other special operations are not required. In addition, linkage with Active Directory allows single sign-on authentication when using protected electronic files, relieving you of the hassle of password entry.

InfoCage FileShell allows you to use applications while maintain file protection.

InfoCage FileShell keeps protecting electronic files even while you use an application. As you can view and/or edit protected files based on your user rights, you do not have to protect the electronic files again after use. Files remain protected even when copied and saved under a new name or otherwise manipulated.

InfoCage FileShell protects against careless mistakes such as forgetting to protect files.

Electronic files are automatically protected when saved in the location protected by InfoCage FileShell such as on a client PC. This prevents electronic files from being inadvertently left unprotected.

InfoCage FileShell provides security even if electronic files are leaked.

InfoCage FileShell protects electronic files individually. Even if electronic files are leaked, they cannot be opened by users who do not have the correct rights. This prevents the risk of information leakage even if electronic files are leaked through a targeted attack (APT: Advanced Persistent Threat) or other illegitimate activity.

InfoCage FileShell enables access control tailored to different usage scenarios.

The access rights to electronic files (viewing, saving, printing, copying to the clipboard, capturing screenshots) can be controlled for each group or user. This enables access control tailored to different usage scenarios such as control according to department or job title.

InfoCage FileShell provides global support.

InfoCage FileShell supports Japanese, English, Traditional Chinese, and Simplified Chinese.
InfoCage FileShell provides support for developing your business globally by helping you share design information with overseas departments.


Central management using policies

The operations that can be performed on client PCs can be controlled based on the policy specified in the InfoCage FileShell server. The electronic files to be protected, applications, automatically protected areas, policy used for manual protection, and other data can be centrally managed.

Automatic update of InfoCage FileShell client

InfoCage FileShell client can be always up to date because client module can be automatically updated.

Easy implementation without InfoCage FileShell server

Policy can be set up with InfoCage FileShell client in order to protect electronic files by IRM. This is useful for trial implementation and small-scale operations to a particular department.

Automatic protection of electronic files by using IRM

Electronic files are automatically protected when saved in the specified automatically protected area.
The user does not have to perform any special operations. Protected electronic files are easy to identify because a padlock mark is added to the original icon.

Automatic protection of electronic files by using IRM on a network

Folders on the network can also be specified as an automatically protected area. In this way, different protection policies can be used for each electronic file depending on your purpose.

Protection using policies that suit your purpose

With InfoCage FileShell, several protection policies can be specified and managed. These can be selected from the menu. In this way, different protection policies can be used according to the purpose of each electronic file.

Application control based on access rights

Protected electronic files are controlled based on the access rights assigned to the user in advance.
