Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Achieve effective email management while identifying areas for security upgrades
There are a couple of issues we have encountered while using Trend Micro Worry-Free Services Suites for the past four or five years. The first is the Business Email Compromise (BEC) issue. Even though we configured the business email compromise option, we still face this issue sometimes where people are getting emails directly with our email ID. We were not able to get a satisfactory answer from them regarding the BEC issue. The ransomware protection issue for the old servers or outdated servers and recovery of the data needs improvement in Trend Micro Worry-Free Services Suites. The ransomware protection issue for old servers and business email compromise also needs to be upgraded because even though it's configured, we still face this BEC issue. The response time of the support also needs improvement.
