https://fiberserver.net.tr/knowledgebase/article/advanced-network-security-fortinet-firewalls

FortiGate appliances combine firewall policy enforcement with security services such as VPN, application control and intrusion prevention.

## Start with network design

Document WAN, LAN, management and server segments. Use least-privilege policies and avoid broad any-to-any rules.

## Secure administration

Restrict management access, use strong authentication, keep firmware supported and back up configuration before changes.

## Monitor and review

Enable useful logging, send critical events to a central system and review denied traffic before modifying rules. Security profiles must be tested to avoid disrupting legitimate applications.
