Stop Spam Email

Unsolicited email in the form of spam costs corporations and government agencies billions of dollars every year. Employees spend time sorting and deleting spam from their regular email while servers and networks have to contend with the extra traffic generated. In addition, spam emails are the most common means with which bots propagate, and often contain malware and links to inappropriate sites.

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 Antispam 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.
