If your organization handles up to 500 simultaneous devices (e.g., laptops, phones, access points), the TZ400 is an excellent choice. However, for environments exceeding this (such as large schools, multi-branch offices, or high-density Wi-Fi networks), upgrading to a higher-tier device like the TZ470 or TZ600 is recommended to maintain performance and stability.
Ideal Use Cases.

Small and Medium Businesses (SMBs)
-
Branch Offices
-
Retail Outlets, Clinics, and Schools
-
Remote or Mobile Workforces
-
Organizations requiring integrated wired/wireless protection
