AhnLab TrusGuard vs FortiGate

Both stand on unified threat management. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

FortiGate combines firewall security, networking, centralized management, and cloud deployment options across hybrid environments. Buyers should review FortiGuard bundle contents, especially the ENT limitation for OT-specific device and protocol recognition.
