Good anti-spam and large file sending capabilities, good training, and easy to set up
Pros and Cons
  • "The Large File Send feature comes in handy when you have to send fairly large attachments."
  • "Technical support has been slower than it was in the past, likely due to the pandemic."

What is our primary use case?

We primarily use this product to journal our email. If there is a disaster, for example, and our primary and secondary data center goes down, we can turn it on for email continuity. 

We don't take advantage of the archiving capability.

What is most valuable?

The two most valuable features are anti-spam and Large File Send. I know a lot of people that have Mimecast in front of Office 365 because it's a pretty good firewall in front of your email.

The Large File Send feature comes in handy when you have to send fairly large attachments.

They provide training classes online, where you can review with an instructor.

What needs improvement?

Technical support has been slower than it was in the past, likely due to the pandemic.

For how long have I used the solution?

We have been using Mimecast Mailbox Continuity for approximately five years.

What do I think about the stability of the solution?

It has been stable for the past couple of months, although last year wasn't too good because there were a couple of service interruptions. I think that it was related to some upgrades that they were doing.

What do I think about the scalability of the solution?

With respect to scalability, we sometimes point to third-party solutions and it integrates pretty well with other products.

How are customer service and support?

The technical support is pretty good. It changed recently, and I think that they're in the process of revamping it. I think that due to COVID, it is definitely taking longer for some things to be taken care of.

Which solution did I use previously and why did I switch?

Prior to Mimecast, we were using Symantec MessageLabs. The support that we were getting from Symantec was not good. The problem with Symantec products is that they start well, but eventually, they are not good enough.

How was the initial setup?

The initial setup is easy and the process is informative.

Besides the online classes that are available, there's someone that will guide you through a good part of the setup as far as getting everything in place and migrated, so they make it pretty easy.

What other advice do I have?

My advice for anybody who is considering this product is to test it out, although it's always good to look at other vendors, too. Mimecast is pretty good, even if you're on Office 365.

This is a product that is definitely needed today.

I would rate this solution an eight out of ten.

Which deployment model are you using for this solution?

Protects your organization from all types of threats
Pros and Cons
  • "The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
  • "The detection rates are an area for improvement."

What is our primary use case?

Mimecast security in general, it's a SaaS service so they have their servers; they have everything on their side and we're just quote-unquote, passing the traffic through them, the email traffic through them.

Mimecast has multiple different solutions, all linked to the email. They recently added user info security training, but we're not using that. We, however, are using the archive piece and we're currently using their security threat protection. Regarding the threat protection — that does just fine. As far as the security goes — they had a big hiccup earlier this year where they were giving a false positive to a bunch of attachments. I'm not sure what happened on their side but for one week at least we had that issue. It took them a little over a week to resolve the issue. We also had some minor incidents after that, that they resolved.

Generally speaking, other than that event, it has been good. It doesn't block a hundred percent of the security threats received, but you have a lot of options to tag or even further analyze the messages received through Mimecast, either to a third-party solution or through an endpoint solution.

Everyone uses this solution at our company, whether they know it or not because you can leave it as transparent as you want it, or as user-demanding as you want it. There are specific items that only IT uses, but in general, this solution is used by one hundred percent of the company.

How has it helped my organization?

Recently they added a stress threat dashboard, which basically gives you metrics on the security side. It tells you how many threat detections were found, how many users were targeted, what were the specific threats discovered slash detected. This has proven to be a great tool for our company.

What is most valuable?

The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature. They have a process where whenever they receive an email with an attachment, they process the attachment through a sandbox. Depending on your configuration, this is a customer-specific configuration, you can tell it to do a bunch of things. You can block the attachment, you can create a safe version of the attachment, or you can tell it to let it go or put it in a help queue for either user moderator or administrator review. 

What needs improvement?

The detection rates are an area for improvement. The other opportunity area I see with Mimecast is that when you're searching inside of the admin console and you detect malicious emails that bypass Mimecast security: let's say you had a hundred of those messages there. Mimecast doesn't have a way to group those and submit one single report to Mimecast. You have to do one at a time which is not really very conducive — it's very time-consuming.

Those are the main two points. If they work to fully resolve those two issues, that would make this an awesome tool. I mean, it's a good tool, but it would be even better.

The main feature that will help everyone will be a different way to submit phishing or malicious emails that went through security. That would be a very good feature I would like to see in the next release.

For how long have I used the solution?

We've been using Mimecast since 2013.

What do I think about the stability of the solution?

Stability-wise, I would give this solution four and a half stars out of five.

What do I think about the scalability of the solution?

The scalability is not even an issue — it's a SaaS solution.

How are customer service and technical support?

The challenge with the Mimecast support is that unless you do a phone call, you're going to have to wait for someone to get back to you. Sometimes, you don't have the time to just call in, unless it's a critical matter that you need to resolve right away.

In general, they rely a lot on their knowledge base, which has very good information, but there are some specific items that are not either clear on the documentation or are not covered in the documentation. On average, I would say maybe we submit a ticket to them every other month — it's not a big deal on that side.

Which solution did I use previously and why did I switch?

We used to use another solution, but we switched over to Mimecast because it has higher catching rates.

How was the initial setup?

The setup was very straightforward for the actual Mimecast solution. If you're talking about the specifics of the security piece, the security piece does take you some time because, by default, it might block more emails than you want it to block, or let other emails get in than you want to get in. You have to create specific rules for impersonation attachment protection. If you're using URL protection, that's another whole thing to set up. 

What about the implementation team?

We took care of the deployment in-house, with no outside help.

You can be up and running in no time. You just have to update a couple of your records. It's not the getting up, it's getting it where you want it to be. It's, quote-unquote, customizing the security levels of perfection you want. That's why it takes time — It's an ongoing task. It's not something that you should set up and let go of. You have to keep adding, removing, or tweaking the settings as needed.

What was our ROI?

I can say that the recently released threat dashboard gives you an idea of how successful you are being with the solution.

What's my experience with pricing, setup cost, and licensing?

The licensing costs are per-user for the product that you get with them. It varies a lot. Then you have different discount tiers depending on the size of your organization or the partner you're using. I mean, there's a lot of quoting with the Mimecast solution. 

As far as additional costs are concerned, there are some for product licenses that you also have to pay — also, the support on Mimecast, the base support doesn't include email or phone calls, I think. In other words, there is a big fee for additional support on top of the per-user cost.

What other advice do I have?

Mimecast has been in the market for a long time. It's a good tool if you want to simplify your operations. It's a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides. I would recommend that you just keep that in mind.

On a scale from one to ten, I would give this solution a rating of nine. If they corrected those two issues that I mentioned, then it would be an 11.

Good security, pretty reliable, and good support
Pros and Cons
  • "The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
  • "The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."

What is our primary use case?

We use it for email availability. In case our on-premises mail servers go down, we switch over to this solution. 

We also use it for security. It has a security element, and it does malware checks. We are looking into purchasing Mimecast Email Security 3.0. 

What is most valuable?

The security is pretty good, and that's why we're going to upgrade to an even more advanced package. 

We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good. 

What needs improvement?

The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. 

It retains your email for 45 days. They can maybe increase this duration.

How are customer service and technical support?

The support has been quite good.

Which solution did I use previously and why did I switch?

We are currently using Continuity, but we are moving our email to Office 365.

Previously, we used a Barracuda device. At that stage, we wanted to use the actual continuity feature, and Barracuda was only offering anti-spam. We also wanted the benefits of a cloud solution and not having to worry about the Barracuda device going down. We switched because of the reliability and availability requirements, and it was more functional.

How was the initial setup?

It was fairly simple. The only issue was trying to find the correct method to do a certain thing, but I didn't battle too much. I didn't have to use support. It was fairly straightforward.

The main deployment probably took a couple of days. There was some work here and there for a few months, but everything was up and running in a couple of days. 

What about the implementation team?

I did the installation, and I am also responsible for its maintenance.

What's my experience with pricing, setup cost, and licensing?

Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not.

What other advice do I have?

I would recommend this product. It is reliable and easy to use. It is a good product.

I would rate Mimecast Mailbox Continuity an eight out of ten.

Which deployment model are you using for this solution?
