However, it was somewhat difficult to block URL-based threats and the security settings were complex, making it difficult for us to use features beyond basic security.

The customer support has been inconsistent with Trellix lately because there is a whole loopback hierarchy that you have to reach the customer service first, and then the engineer will respond, and then the customer service will feed you back again.

Threat intelligence is adequate because they are using Microsoft GTI threat intelligence, but we need to increase protection against phishing and spam mails.
