Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"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."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The most valuable feature is the straightforward setup."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"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."
"I have been satisfied with Mimecast Email Security as a good solution."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"The most valuable feature is the DMARC Analyzer."
"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."
"It has all the features required for distribution, such as the ability to mail."
 

Cons

"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."
"The solution is not 100 percent stable and that can use improvement."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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."
"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."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."
"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."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"While it's quick and easy, the initial setup could be more user-friendly."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"The product's interface could be improved to be more user-friendly."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
 

Pricing and Cost Advice

"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."
"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 product price is moderate. I rate the pricing a five out of ten."
"It's an expensive solution."
"The customers can select the license packages as per their requirements."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The price of Mimecast Mailbox Continuity is expensive."
"For what it is, the product is overpriced."
"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."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
