Internet Gatekeeper for Linux

IMPORTANT information regarding F-Secure Internet Gatekeeper version 5.00.
This release of F-Secure Internet Gatekeeper does not contain a Web User Interface.
If you upgrade to 5.0, the Web User Interface installed with the earlier version will be uninstalled.
Users needing the Web User Interface should not upgrade at this time.
A new Web User Interface will be included soon in the upcoming release of F-Secure Internet Gatekeeper

High-performance protection at the gateway level

  • Scans and protects e-mail, web traffic and file transfers
  • Stops threats before they spread inside the corporation

What’s new in this release:

This release contains the following new features, bugfixes and other changes that have been added since the 4.10.17 release.


-Support for F-Secure Real Time Protection Network was added to the HTTP proxy. When enabled, common files are identified by rapidly updating black and white lists. This saves system resources and improves protection.

-The malware scanning capabilities are now available by a standard ICAP interface. This enables integration with third party proxies that support ICAP.

-The list of supported distributions was reworked to focus on the most popular, current and actively supported distributions.

-Removed dependency to Java, which is a common source of security vulnerabilities. Java runtime environment is no longer distributed with the product. As a consequence, this release does not contain a web UI, but is also significantly smaller and lighter. Configuration is done by editing the configuration files directly.

-Improved quality of RPM packages. -Improved the output from IGK init scripts.

-Fixed CTS-91383: Added an option to control whether to transparently re-establish keepalive upstream HTTP connections.
