Security
In most deployment scenarios, we recommend you deploy FortiGate to secure your network. Fortinet includes security functionality in the FortiADC system to support those cases when deploying FortiGate is impractical. FortiADC includes the following security features:
Firewall—Drop traffic that matches a source/destination/service tuple you specify.
Security connection limit—Drop unusually high volume traffic from a source/destination/serve match.
IP reputation service—Drop or redirect traffic from source IPs that are on the FortiGuard reputation list.
Denial of service protection—Drop half-open connections to protect the system from a SYN flood attack.
