HM
CEO at Cyber Internet Services (Pvt) Ltd.
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.

Block significant threats with enhanced phishing prevention
In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage. A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently. Security is a major feature where email security tools like Mimecast have delivered value by identifying and preventing phishing emails.

Quotes from Members

Pros

"I have a lot of control over spam and phishing emails."

"Hornetsecurity 365 Total Protection is an easy-to-use solution."

Cons
