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 most valuable features are the anti-phishing and anti-spam capabilities."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature is the straightforward setup."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"Mimecast certainly helped my customers reduce phishing emails."
"It offers an easy initial setup."
"The initial setup is easy."
"The solution offers good technical support."
"I have been satisfied with Mimecast Email Security as a good solution."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"The initial setup is very straightforward."
 

Cons

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The solution is not 100 percent stable and that can use improvement."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"They should improve the cookies management feature."
"The attachment scanning feature doesn't work properly."
"They could provide a unified licensing model, including all the security features."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"While it's quick and easy, the initial setup could be more user-friendly."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"As a user, the user interface of the management console could be upgraded, for example."
"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."
 

Pricing and Cost Advice

"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"The solution is not expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"My company makes annual payments towards the licensing costs solution."
"It's an expensive solution."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"We pay monthly fees to our provider."
"The product has good pricing in terms of return on investment."
"The product price is moderate. I rate the pricing a five out of ten."
"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."
"For what it is, the product is overpriced."
