Introduction
F-Secure Internet Gatekeeper for Linux is an Internet Gatekeeper solution designed to protect
corporate networks, Internet Service Provider networks, and home networks against malware.
Computer viruses are one of the most harmful threats to the security of data on computers. Viruses
have become even more widespread due to the trend in standardizing platforms and the continuous
spread of the Internet. In addition to corrupting or falsifying data, viruses can also cause damage by
using the Internet to leak confidential company data or personal information. Even if the leaked
information is not important in itself, viruses can use the computer to spread their infection more,
resulting in harm to others.
With F-Secure Internet Gatekeeper for Linux, you can scan for viruses centrally. You can monitor web
site connections, and the sending and receiving of e-mails from all computers in a LAN (Local Area
Network).
The product can scan communication that is based on HTTP, FTP, SMTP, and POP.
The ability to use the POP protocol means that you do not need to make any changes to the mail
server to check e-mail for viruses. You can simply pass all inbound and outbound e-mail through
F-Secure Internet Gatekeeper for Linux.
The product is very fast, being optimized for performance. This makes it suitable for large-scale
networks, and for networks that support high-speed broadband. It also means that performance is
adequate even when the product is run on less powerful computers.
The product also supports a transparent proxy, various authentication functions, and spam blocking.
The product is available also in Japanese.
