Do I need a Gateway Firewall for an IoT network

Question

I’m setting up an IoT network and wondering whether a Gateway Firewall is necessary.

• Since IoT devices are often vulnerable, would a Gateway Firewall improve security significantly?
• Can a software-based firewall on individual devices offer similar protection?
• What are the best practices for setting up firewalls in an IoT environment?

Would appreciate insights on whether a Gateway Firewall is a must-have for IoT security.
