ReaSoft Network Firewall is a powerful solution that was developed specially for small and medium-size businesses, with due consideration of their specific needs and problems. The program has already won significant popularity thanks to its excellent performance combined with minimal requirements and ease of use.

Besides regular firewall functions, ReaSoft Network Firewall 3 is noted for elements of Data Loss Prevention system. Of course, they do not make it a full-featured DLP system, but they have proved more than sufficient for monitoring and tracking tasks. ReaSoft Network Firewall detects and prevents leakage of confidential information through e-mail, web-mail, ICQ, MSN, Internet communities and other similar channels. All HTTP and HTTPS POST queries, communication via instant messengers and e-mails with attachments are decoded by the program and saved on the hard disk for checking. Given that full-fledged DLP systems are very expensive and require significant implementation effort, ReaSoft Network Firewall is an affordable yet effective substitution.

Another important feature is web filtering based on the program's catalog of websites. It would be very useful for those managers or business owners who would like to boost their employees' productivity. According to recent surveys, 90 percent of American office workers do online shopping and surf social networks during office hours. It means that simply blocking access to all websites categorized as "Electronic commerce", "Social Networking" and "Entertainment" (by creating a correspondent rule in ReaSoft Network Firewall) eliminates the so-called "cyber-slacking", greatly increases the employees' labor efficiency and, consequently, corporate income. By the way, traffic consumption considerably drops.
