Why you need GFI MailSecurity
Email security is an essential part of network protection strategy. To achieve proper email security, you need a comprehensive package that defends your system against different types of email threats, using a combination of different technologies. This white paper highlights why you should have a multi-layered approach to email security and presents a simple checklist to help you determine whether you need GFI MailSecurity for Exchange/SMTP.

GFI MailSecurity's deployment strategies: Which operating mode(s) to use in your network environment
GFI MailSecurity can be deployed in two operating modes: Either as an SMTP gateway or as a VS API version for Exchange 2000. It can be used in three ways, either by using one of these modes or by using both in tandem. This paper describes the GFI MailSecurity operating modes in detail and helps you choose the best way to deploy GFI MailSecurity on your network.

One virus engine is not enough: The case for maximizing network protection with multiple anti-virus scanners
This paper studies a number of anti-virus engine tests which reveal that each virus scanner presents its own strengths and weaknesses. As no single anti-virus engine can fully protect against all possible threats, this paper examines how simultaneous use of more than one virus engine can achieve greater security than is technically possible when relying on one anti-virus engine alone.

Why you need an email exploit detection engine: Companies must supplement anti-virus protection for maximum security
Virus-writers are using increasingly complex and sophisticated techniques in their bid to circumvent anti-virus software and disseminate their viruses. Email security tools must evolve in the same way if such threats are to be blocked before they can cause harm. This paper examines how anti-virus software, though essential, cannot combat such threats and shows why an email exploit detection tool is also necessary.

Protecting your network against email threats: How to block email viruses and attacks
This white paper describes various methods used by email viruses and worms to penetrate a protected network. Such methods include attachment files containing harmful code, social engineering attacks, crafted MIME headers, malicious use of HTML Script and similar technologies. A URL is provided where you can test whether your email system is vulnerable to threats like these. This document also examines the ways through which email can be sanitized and filtered of malicious code.

Why anti-virus software is not enough: The urgent need for server-based email content checking
This white paper explains why anti-virus software alone is not enough to protect your organization against the current and future onslaught of computer viruses. Examining the different kinds of email attacks that threaten today’s organizations, this paper describes the need for a solid server-based content checking solution to safeguard your business against email viruses and attacks.
