A great solution for monitoring emails with a valuable URL protection feature
Pros and Cons
  • "It has all the features required for distribution, such as the ability to mail."
  • "Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."
  • "The solution is expensive in comparison to similar solutions."
  • "The differentiation between bulk spam mail and campaign-related mail could be improved."

What is our primary use case?

Our primary use case for the solution is for monitoring emails. It also flags and highlights suspicious and new emails. Overall, it protects from malicious emails within or outside of organizations. Mimecast Mailbox Community is an email gateway required for every organization, regardless of size.

What is most valuable?

The URL protection feature is valuable because it communicates all attachment-related activity and provides access to view the content of the message directly. Additionally, it can directly provide you with the content of emails if you have been granted access.

What needs improvement?

The differentiation between bulk spam mail and campaign-related mail could be improved. Campaign-related activities are challenging to find in Mimecast Mailbox Continuity. For example, in an organization with a hundred people working for you, there will be approximately 100 email IDs. As a sender, if I want to spoof some people in the organization and hack their credentials, I need to identify targets for the phishing campaign. So I could use an email address to spoof a Microsoft page or create a fake page impersonating Microsoft to harvest credentials. By sending a hundred people a hundred emails with the same subject and same sender, with the same URL, this will easily be detected. So the second option is to spoof the sender every time by sending a hundred people a hundred URLs with similar subjects. In the second scenario, Mimecast Mailbox Continuity is not very good at detecting it.

For how long have I used the solution?

We have been using this solution for approximately five months.

What do I think about the stability of the solution?

The solution is stable.

What do I think about the scalability of the solution?

The solution is scalable because it works on cloud and accepts over a thousand emails daily, so the storage must be higher than other solutions.

How are customer service and support?

I rate the customer service and support team a ten out of ten. We have only had to contact them once, and they were quick to resolve our issue.

How was the initial setup?

The initial setup is easy compared to other environment configurations because you will have to install the same information into an Exchange Server. However, once it is integrated, it's easy to configure.

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

The solution is expensive in comparison to similar solutions.

What other advice do I have?

I rate the solution a nine out of ten. My advice to users considering this tool is to explore everything. It has all the features required for distribution, such as the ability to mail. Explore every option available and check for tags.

Great reporting , good visibility, and feature-rich
Pros and Cons
  • "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."
  • "I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
  • "While it's quick and easy, the initial setup could be more user-friendly."

What is our primary use case?

We use Mimecast Email Security with Targeted Threat Protection for email security.

What is most valuable?

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 does have integrations, and there is an app that can be added to Outlook to allow them to do what they need to do. 

While some of the setups are probably not as user-friendly as some of the other platforms, there is a lot of customization that you can do to the platform to help you pull up a lot of stuff that shouldn't be going into users' mailboxes.

I believe the world is going through a crazy period right now, and everyone is attempting to penetrate different systems as quickly as possible and change their ways of doing things. 

I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues. Overall, I'm pleased with them. I think I just look at what's out there every year during renewal time to see if we're still on the best platform or if we should consider migrating to something else.

It has great reporting, and we can see what's going on.

I am pleased with the features we have at the moment and everything it does; it's only one piece of the puzzle for our environment, but I'm pleased with how it detects things and some of the functionality that we have had to set up due to the complexity of our business and security. I'm pleased with everything. I don't have anything specific in mind that I'd be looking for.

What needs improvement?

While it's quick and easy, the initial setup could be more user-friendly.

For how long have I used the solution?

I have been working with Mimecast Email Security with Targeted Threat Protection for two or three years.

What do I think about the stability of the solution?

I did not have any issues with the stability of Mimecast Email Security with Targeted Threat Protection.

Maybe once in the last year, but it was a short period of time. Everything comes through. The capabilities during the impersonation protection, integrating with some of our various partners, and so on so that we can work seamlessly with them as well. Overall, I found it very easy to work with them.

How are customer service and support?

Technical support is good. I haven't had any problems with technical support.

Obviously, there is a paid add-on depending on the level of support you require, but they are extremely responsive. Whenever I call in, they usually resolve my issue right away, we'll go over it and give me a callback. It's not like I'm waiting weeks or months for a response. So far, so good.

How was the initial setup?

To be honest, the initial setup was very quick and easy. I had a quick turnaround because I was transitioning away from another company we were using called AppRiver and their SecureTide product, which was okay but not my favorite. I didn't like the integrations and other procedures we had to go through, and the Mimecast product seemed to fit better in comparison.

What other advice do I have?

There is a lot of functionality that we haven't fully taken advantage of. 

I would say, make sure you are selecting a product that best fits your business.

Some things will be added as you go through the implementation process. Since our implementation, items have been added, and with some of the functionality that they have, we simply don't have the time to assess and determine what we require.

I would recommend reviewing everything that comes with your product license and ensuring that it is covered when you go through the implementation process.

I would rate Mimecast Email Security with Targeted Threat Protection an eight out of ten.

Reliable, and protects emails from threats, including spam
Pros and Cons
  • "It's good, it keeps the spam out."
  • "It's good, it keeps the spam out, and it does a really good job at not allowing threats through."
  • "The filtering needs more flexibility."
  • "This solution can be frustrating. It blocks many things that should be going through."

What is our primary use case?

I am an investment research analyst. We use this solution for spam and as our security filter.

What is most valuable?

It's good, it keeps the spam out. 

It does a really good job at not allowing threats through.

What needs improvement?

This solution can be frustrating. It blocks many things that should be going through. I have to authorize permission, which seems to be a frequent occurrence. It may be that we have set our protection too high but we work in a regulated industry.

When you click to change permissions on something, it always launches a browser instance to tell me that I have taken an action. I have to close that out and go on to the next one, and when I asign permission another item, again it opens up a browser again to notify me that I have taken action. I don't know why it does that or why it is necessary.

The filtering needs more flexibility.

For how long have I used the solution?

I have been using Mimecast for four or five years.

What do I think about the stability of the solution?

I have not had any issues with the stability of Mimecast Email Security with Targeted Threat Protection. We have not experienced any glitches or bugs.

How are customer service and technical support?

I have not contacted technical support.

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

I am not familiar with the pricing.

Which other solutions did I evaluate?

I have researched Magic Software. I wanted a better understanding of the differences in the offerings. I allocated capital, I am trying to see if Magic is a good holding for our small-cap portfolio. 

It is abstract but I don't do any application development.

What other advice do I have?

I would rate Mimecast Email Security with Targeted Threat Protection an eight out of ten.

Which deployment model are you using for this solution?

On-premises

Good gateway and email security with an easy initial setup
Pros and Cons
  • "It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
  • "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."

What is our primary use case?

We use Mimecast as our email gateway. We also use it as our archival service. All those phishing, anti-phishing, spear phishing, spamming, and other security filters that they have, we use all of them.

What is most valuable?

We have found email security very good.

The gateway is excellent. 

We have found the archival services to be very valuable.

It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge.

The initial setup is straightforward.

What needs improvement?

It was not so much about the product itself, however, their business model needs improvement. 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. This is something which really worries us as a company.

For how long have I used the solution?

I've used the solution for about six years at this point. It's been a while.

What do I think about the stability of the solution?

The solution is stable. There aren't bugs or glitches. It doesn't crash or freeze. It's very good.

What do I think about the scalability of the solution?

The solution can scale well. If a company needs to expand, it can do so rather easily.

We have grown from about 2,600 users to about 4,000 users. We have added additional geography as well. The product is resilient enough to take care of all of this.

How are customer service and technical support?

We have contracts and we are also subscribed to a service plan. Whenever we have used it, the service levels have been very good and we have no reason to complain.

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

We were previously thinking of an alternative to Mimecast for two reasons. The main reason is as an organization, we are in the financial service industry, and we have to show some data resiliency to our regulators. However, due to the fact that we're present in 30 countries, what happens is all Mimecast data is centrally hosted in one particular grid, which is preventing us from showing data resiliency to them. I want a solution that allows me to selectively map users to a particular geography. 

How was the initial setup?

We didn't find the initial implementation complex. It was pretty easy and rather straightforward.  We didn't run into trouble.

We are a complex organization. We are present in 30 countries. It was a mix of on-prem and some were in Office 365. Due to the set up of our own architecture, we had to undergo some labor, however, otherwise, the entire process was pretty straightforward.

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

We typically use a subscription service. If there are version upgrades. We automatically get upgraded to the latest version, as it's a software as a service setup. We don't need to update it as Mimecast takes care of it.

If you need to extract data from their archival service, there is an additional fee involved.

As we are an enterprise customer and we have a relationship with them, what we are told by the reseller is that we pay about 40% of their list price for this product.

It's an expensive solution. There are other competitors, like Barracuda, who offer similar services. We believe that over the years, they have picked up, and their pricing is much more competitive than Mimecast. As an organization, Microsoft itself has really matured over the years. They offer probably 90% of what Mimecast is offering, and then you don't have to pay anything extra for it because it comes with part of the Office 365 licenses. That is why we also believe that there is a lot of room for Mimecast to get their act together, pricing-wise.

Which other solutions did I evaluate?

We evaluated a few other options such as Cisco IronPort as a security service. We evaluated Proofpoint. The comprehensive solution that Mimecast offers, however, really made us sign on the dotted line.

What other advice do I have?

We're just an end-user.

We use their Perimeter Defense plan, we use their Continuity plan, we also use email to archive. These are the three scales that we use from them.

I would advise others considering the solution to technically evaluate their competencies, their highs, and lows, first. Also, read the fine print, and understand the exact costs. A company will need to understand natively how much of Mimecast capabilities does Microsoft offer if you just subscribe to an Office 365 license. It might make them rethink using this solution.

From a technical standpoint, I would rate the solution eight out of ten.

The solution is used for banking and finance clients. 

What is most valuable?

The most valuable feature is the DMARC Analyzer.

How was the initial setup?

The setup is really easy. You do not need to install it on-premises. You can install it on the cloud with any desktop. The deployment takes one hour.

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

The solution is expensive.

What other advice do I have?

Overall, I would rate the solution an eight out of ten.

What other advice do I have?

Based on my experience, I would rate it nine out of ten.

It offers an easy initial setup. 

The solution has been stable. 

We can scale the product.

We are satisfied with the technical support. We find them to be responsive. 

How would you rate customer service and support?

Positive

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

We did previously use a different solution. It might have been Check Point. Once we saw the demo, we felt this solution would be a better fit, so we switched. 

How was the initial setup?

The solution is very simple to set up. It's not overly complex or difficult. The deployment only takes a couple of days. 

One person can handle any maintenance requirements as needed. 

What about the implementation team?

Gives businesses continuity; best suited for scaling in large and medium-sized enterprises
Pros and Cons
  • "Mimecast has some good support services in place."
  • "Mimecast Mailbox Continuity helps companies continue to move."
  • "I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."

How has it helped my organization?

Mimecast Mailbox Continuity helps companies continue to move. It allows them to continue to function and utilize email even if there's a downstream issue with your exchange server or online email server. If either of those goes down or offline for maintenance or any other purpose, users will still have access to their mailboxes and be able to send and receive emails. It gives companies business continuity.

What needs improvement?

I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats. They do have SMB packages, but I think from a complexity standpoint, it's better suited to medium to larger enterprises.

What do I think about the scalability of the solution?

I would say it's scalable in large and medium-sized enterprises. 

How are customer service and support?

Mimecast has some good support services in place.

What other advice do I have?

A feature like Mimecast Mailbox Continuity is likely not something that people ask for but it is nice to have and well done. Continuity is normally sold as part of an email protection bundle, so I don't know if you can even get it separately.

It does exactly what it promises to do
Pros and Cons
  • "Mimecast certainly helped my customers reduce phishing emails."
  • "Mimecast is a brilliant product; it works very well, I have very seldomly, if ever, had any problems with it, and it does exactly what it promises to do."
  • "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."

What is our primary use case?

My customer base is made up of small clients. They all fall between five and 10 users.

How has it helped my organization?

Mimecast certainly helped my customers reduce phishing emails.

What is most valuable?

Among my customers, there was a lot of traction for the archiving. The targeted threat protection was also quite useful.

What needs improvement?

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.

For how long have I used the solution?

I've been using Mimecast for five years. I used to be a reseller, but now I've moved on to a different business.

What do I think about the scalability of the solution?

As far as I'm concerned, it worked exactly the same for a client that had one mailbox as it would for a client that had 500 mailboxes.

How was the initial setup?

I've never set Mimecast up. The technical teams did that. From my understanding, it took them about two days to set it up. 

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

Mimecast is expensive. It's a premium product. It sometimes could be a difficult sell because of the cost.

Which other solutions did I evaluate?

I don't have anything to compare Mimecast with because I haven't looked at any of the others yet to see if there is something comparable. But I would presume that by now there will be other products that can compare to it. To get security and targeted threat protection, one could potentially look at Sophos Central Email Protection. But they don't have an archiving solution. So one would have to go somewhere else to get an archiving solution. With Mimecast. at least, it's all available from the same vendor, if that makes sense.

What other advice do I have?

I would rate Mimecast nine out of 10. It's a brilliant product. It works very well. I've very seldomly, if ever, had any problems with it. It does exactly what it promises to do. At the same time, it is expensive. That's the only problem. And the price tag puts it out of the range of smaller businesses. That's where I think it falls flat. But I always tell people the same thing: If security is important to you, then certainly spend the money and get it, because Mimecast is a great product and it works.

Easy-to-use admin console, simple to set up, and designed for enterprises
Pros and Cons
  • "Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
  • "If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
  • "Its pricing can be improved. It is a bit expensive."

What is our primary use case?

We use it internally, and we support other customers on it. Enterprises and large organizations use it to manage their platform on a large scale.

It is a cloud product, so it is always going to be the latest version. Mimecast themselves are the cloud provider.

What is most valuable?

Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it.

What needs improvement?

Its pricing can be improved. It is a bit expensive.

For how long have I used the solution?

I have been using this solution for five years.

What do I think about the stability of the solution?

It is stable.

What do I think about the scalability of the solution?

It is suitable for small, medium, and large companies. It actually cuts across all the sectors and all the sizes. It is designed for enterprises.

In terms of the number of users, it affects all the users. We have over a hundred people at the moment. We also have more than 20,000 customers on it.

How are customer service and technical support?

Their technical support is pretty good.

How was the initial setup?

Its initial setup is pretty simple. It takes nearly a day.

In terms of maintenance, it is online. So, they do all of the maintenance.

What about the implementation team?

I did it by myself.

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

It is a bit expensive.

What other advice do I have?

If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go. It has been a good product. It is still at the top of its game in many aspects.

I would rate this solution a nine out of 10.
