Product Contents

F-Secure Internet Gatekeeper is a gateway product that acts as a virus scanning proxy for HTTP, SMTP, POP, and FTP protocols.

The product uses F-Secure’s scanning technologies to scan for malware. They provide outstanding protection level and fast, automatic updates to the scanning engines and anti-virus databases. With F-Secure’s Security Cloud, the product can react to new threats rapidly, which keeps the users protected and enhances the protection even further.

The product can be integrated with third-party HTTP proxies with the standard ICAP protocol. The content that is submitted to the ICAP service is scanned with F-Secure’s malware scanning technologies.

New Features

This release contains following new features, bugfixes and other changes that have been added since the 5.20.646 release.

4.10.17 => 5.00.5

  • 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 the 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.

If you are upgrading from a version earlier than 4.10.17 ,4.11.8 or 4.12.5, see the release notes of version 4.12.5 for a list of earlier changes.

Known Issues

  • Upgrading from any 2.X or 3.X version is not supported. Please uninstall the old version completely before installing F-Secure Internet Gatekeeper 5.20.
  • Upgrading from 4.X Japanese version of the product(virusgw) to international version(fsigk) is not supported. Follow the instruction in admin guide of the product to migrate settings from old(virusgw) installation to F-Secure Internet Gatekeeper 5.10(fsigk) installation.
  • Credentials for accessing services using HTTP proxy (http_proxyauth_user and http_proxyauth_pass in fsigk.ini) have certain limitations. Only the following printable ASCII characters are allowed: letters, digits and the following special characters: -._~!$&'()*+,;=
  • If you use rpm to upgrade the product to the 5.20 release, the product configuration files are reset to the factory defaults. The upgrade process renames the old configuration files by attaching an .rpmorig extension. This does not affect the main configuration file, fsigk.ini. As a workaround, you can rename the backup files back to their original names.
