Featured Reviews

Asif Usmani - PeerSpot reviewer
A stable product that provides security and control over spam and phishing emails
I have a lot of control over spam and phishing emails. I can monitor and manage it from Hornetsecurity’s console. The live tracking system is valuable. We can track every incoming and outgoing email live. We can decide whether to block, release, or quarantine emails. We can also review the emails before releasing them. The product provides 99.9% coverage for email security.
Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

Quotes from Members

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

Pros

"I have a lot of control over spam and phishing emails."
"Backup and restore are precious features."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"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."
"Email security is the most valuable feature of the solution."
"It's good, it keeps the spam out."
"The most valuable feature is the DMARC Analyzer."
"The solution's performance is good."
"The setup was easy."
"The initial setup is easy."
"The solution is pretty straightforward to use and easy to set up."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
 

Cons

"The pricing is a little high compared to other products."
"A reduction of 10% in pricing can be an improvement."
"The solution’s pricing is not reasonable."
"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."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The feature that should be included is to remove the block on the encrypted files."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"Its pricing can be improved. It is a bit expensive."
"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."
"The attachment scanning feature doesn't work properly."
"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 solution should include more AI features instead of Mimecast's more general static configuration tooling."
 

Pricing and Cost Advice

"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
"For what it is, the product is overpriced."
"We pay monthly fees to our provider."
"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."
"It is a bit expensive."
"The product has good pricing in terms of return on investment."
"It's an expensive solution."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The customers can select the license packages as per their requirements."
