FortiGuard Global Spam Filtering

Fortinet applies a comprehensive, multi-layered approach to guard against spam. Global spam filtering is provided through the FortiGuard Antispam service which has access to the Fortinet Global Threat Intelligence database. The FortiGuard team collects and analyzes a constant flow of sender IP reputation and spam signatures from the large installed base of FortiGate, FortiClient and FortiMail platforms. This global database is constantly updated, enabling FortiGate, FortiClient and FortiMail appliances to detect and filter most prevailing spam. In addition, customized spam filters can be created to filter email for banned words, blocked and allowed email sender addresses, heuristic rules, and highly sophisticated techniques such as Bayesian training in FortiMail.

Defense-in-Depth

A large amount of spam is sent everyday by improperly configured or virus-infected host email servers. FortiGuard Anti Spam Service maintains a global IP reputation database where the reputation of each IP address is updated based on information gathered from multiple sources. IP address reputation properties can include ‘whois’ information, geographical location, service provider, host server information, and more. In addition, by comparing each sender's historical email volume with their current email volume, FortiGuard Antispam Service updates the reputation of each IP address in real-time, providing a highly effective sender IP address filter.

We handle a lot of very confidential and time sensitive data for which security is absolutely essential. So, when we decided to move our existing services and systems online for more efficiency, we had to ensure that not only our data would be protected but also that our network would maintain its high performance, delivery throughput and high availability. Fortinet's FortiGate-800 systems provided the performance, flexibility and security we were looking for. Combined with other networked solutions deployed by DPS, we felt that it was the most effective solution for us.
