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

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best part is, I rarely have to access the portal as everything is set up and tweaked the way I wanted it. But the feature set is incredibly granular and allows for deep levels of customization."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"I have a lot of control over spam and phishing emails."
"My advice for people considering using Hornetsecurity 365 Total Protection is that the simplicity is the best option because Hornetsecurity 365 Total Protection includes everything in one platform and provides a 360-degree view."
"Backup and restore are precious features."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"URL inspection works pretty well."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"The solution is pretty straightforward to use and easy to set up."
"Mimecast certainly helped my customers reduce phishing emails."
"The most valuable feature is the DMARC Analyzer."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
 

Cons

"I guess I would say maybe quick access to training material for end-users. I know partners have access to this but I as an end-user do not have immediate access to new update information."
"The pricing is a little high compared to other products."
"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 solution’s pricing is not reasonable."
"A reduction of 10% in pricing can be an improvement."
"The detection rates are an area for improvement."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"Its pricing can be improved. It is a bit expensive."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"The installation is not so straightforward."
"The feature that should be included is to remove the block on the encrypted files."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"They could provide a unified licensing model, including all the security features."
 

Pricing and Cost Advice

"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
"The licensing costs are per-user for the product that you get with them."
"We pay monthly fees to our provider."
"The customers can select the license packages as per their requirements."
"The solution is expensive."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"It's an expensive solution."
"For what it is, the product is overpriced."
