Featured Reviews

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.

Dynamic runtime engine and good protection, but needs better support and a single console
We have two to three issues per month. We contact Proofpoint's customer support for these issues. I am a major point of contact for support. If I am not able to resolve an issue, we will be reaching out to them. Proofpoint can take a couple of days to get back. I also deal with other applications from Okta and Microsoft, and we get the support within a couple of hours. There is a lot of difference between a couple of hours and a couple of days. So, Proofpoint's support should be improved. Okta and Microsoft are also able to do a Zoom or video call, but Proofpoint provides support only through email communication. Only if you request, it would be a Zoom or video session.

Quotes from Members

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

Pros

"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"Mimecast certainly helped my customers reduce phishing emails."
"The solution is pretty straightforward to use and easy to set up."
"The most valuable feature is the DMARC Analyzer."
"I recommend Mimecast based on customer requirements and budget."
"It offers an easy initial setup."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"It has a dynamic runtime engine, which gives it an advantage over Prisma that has a static engine. In Prisma, we have to do additional malware analysis, which is not required in Proofpoint."
 

Cons

"We discussed the phishing aspect, the DNS system, and the key rotation."
"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."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The installation is not so straightforward."
"The price could be better, it should be reduced."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"We are using the TRAP console that has a Linux-based UI, which is not user-friendly. The TAP console looks very advanced. Currently, we are maintaining three different consoles, and it is sometimes hard to switch between them or try to grab the data."
 

Pricing and Cost Advice

"The product price is moderate. I rate the pricing a five out of ten."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The licensing costs are per-user for the product that you get with them."
"The product has good pricing in terms of return on investment."
"The customers can select the license packages as per their requirements."
"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."
"For what it is, the product is overpriced."
"We pay monthly fees to our provider."
