FortiGuard Antivirus, Botnet IP and Domain Reputation - Subscription license renewal (1 year) - for P/N: FG-501E, FG-501E-BDL A key part of a botnet's attack kill chain requires an infected device to communicate with a command & control server - either to download additional threats or to exfiltrate stolen data. FortiGuard's IP and Domain Reputation tools block this communication, thereby neutralizing these threats.
