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.
ShaheenKapery - PeerSpot reviewer
Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

Quotes from Members

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

Pros

"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"Backup and restore are precious features."
"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."
"I have a lot of control over spam and phishing emails."
"Email security is the most valuable feature of the solution."
"The integration is straightforward."
"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."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"The initial setup is very straightforward."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"The solution is pretty straightforward to use and easy to set up."
 

Cons

"The solution’s pricing is not reasonable."
"A reduction of 10% in pricing can be an improvement."
"The pricing is a little high compared to other products."
"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."
"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."
"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."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"The attachment scanning feature doesn't work properly."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The price could be better, it should be reduced."
 

Pricing and Cost Advice

"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
"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."
"It is a bit expensive."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"For what it is, the product is overpriced."
"We pay monthly fees to our provider."
"The product has good pricing in terms of return on investment."
"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."
