Hi,
Trend Micro Maximum Security is like a personal security system for your computer. It protects you from common threats like viruses and online scams, making sure your device is safe while you browse the internet or shop online. It is also for consumer or personal devices.
Trend Micro Endpoint Detection and Response (EDR), on the other hand, is more like a high-tech security team for businesses. It not only detects threats but also investigates them and helps fix problems across many computers in an organization. This system is designed for more complex security needs, often used by larger companies to protect sensitive information.
Hope this helps.
