Comprehensive email protection has secured sensitive communications and simplified threat management
Hornetsecurity 365 Total Protection is a good product right now, and the report is available in Spanish, which is beneficial for Latin Americans who speak Spanish. They can continue to improve the pricing because it is the most important aspect, as another solution is aggressive with a lower cost and includes everything. While Hornetsecurity 365 Total Protection is good right now, it would be better to improve the price. At the end, the client sees the price, and in Puerto Rico, the market is different than in the United States since here the client sees price independent of security. I have more effort to explain the difference between price versus technology, which is important because in Latin America, the price may not be the same as in the US due to the company's increase not being the same volume. When clients have many mailboxes, the price is more important than the technology. I do not know why, but this really happens.

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.

Cons

"A reduction of 10% in pricing can be an improvement."
"They can continue to improve the pricing because it is the most important aspect, as another solution is aggressive with a lower cost and includes everything."
"The pricing is a little high compared to other products."

"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."

"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
