### "Nothing but excellence."

March 14, 2018

5.0

Security

Pros

MimeCast has helped so much in protecting us against Impersonation attacks which were a daily problem. IT helps us block nearly 10 000 Spam mails a week. since i implemented the MimeCast services my daily hours of work have been cut back and my stress levels have lowered. There support is phenomenal which makes me forget that i am dealing with a South African support line.

Cons

If you dont go on some training and try to setup MimeCast by yourself you will battle a bit so take up their offer on training.

### "ABSOLUTELY TERRIBLE"

January 11, 2018

1.0

Just headaches

Cons

We have a 3 year contract, and they do not abide by their SLA's at all. We will be shredding the contract, and moving back to barracuda. Our email system was infiltrated 3 times in a week, even after Mimecast themselves set up the policies to prevent this. They can not support a thing, account reps dont answer, and no one responds. They just want your money for nothing in return.

### "It works, Keep junk mail out"

September 22, 2020

5.0

This stopped us from getting hacked! Good program, works as it should.

Pros

This is a good program. It really does keep junk and malicious mail out of your inbox. I liked the daily updates on what it caught so I could easily add senders to my approved or blocked lists.

Cons

Really none. It could be too sensitive at times but that was resolved with little headache by just approving the sender. However, if you were waiting for a reply and had to go and check Mimecast it could be annoying.

### "Mimecast is a high quality e-mail security service although a bit pricey"

December 28, 2018

5.0

It's just a top notch product, as I said the price is quite high when you look at the competitors however I guarantee you that the support and functionality won't be as good as MimeCasts.

Pros

The functionality of the software is amazing, no matter what your setup or need is I'm sure that MimeCast will be able to accommodate you. The customer support has been amazing, every time I have contacted them they've resolved the issue in a thorough and quick manner.

Cons

The price, it's a high price compared to some of it's competitors however I do firmly believe you're getting what you pay for. I haven't regretted my purchase of the software at all.

### "Safe and Secure"

November 13, 2018

4.0

The filters to search our email archive is fantastic. I've never seen a filter feature that has so many options, including date, keywords, subject, people, etc. Every time I log into the MimeCast portal, I leave finding what I was looking for.

Pros

The new MimeCast personal portal is AWESOME. We recently switched to it from an outlook plugin version. I can't say enough about how easy it is to locate old emails and find emails that may have been blocked or flagged for security reasons. No more having to call the IT guy every time a "reset your password" email comes through. Win!

Cons

I honestly don't have any complaints. This is a very easy way to access my email remotely, search archived email, and filter out unwanted email.

### "Mimecast"

January 20, 2020

4.0

Overall this software is a good idea- we use this company wide.

Pros

I like the added level of security- my entire day I receive emails from unknown senders, but with this added step I can avoid fraudulent activity and viruses.

Cons

Mimecast does flag email addresses you have added to your contacts therefore delaying receipt of communication

### "Lots to like about this product"

October 11, 2017

5.0

Pros

We originally looked at proofpoint, but as a 300 employee company, it was too big and expensive for us. Also, the license count minimums for PP were very high. Mimecast came in about 60 percent less, for very similar services. Our biggest threat was phishing, and executive spear phishing. With a 100% SLA uptime, email continuity, 99 year archiving with unlimited data, and basically just rerouting your MX record, this service is a no brainer.

Cons

My only beef was I was told by sales you could use this with non dedicated hosted exchange at rackspace, but after the sale I was told its not true. We moved to 365.

July 23, 2018

5.0

Pros

very feature rich constantly adding new features to increase layers of protection integrates well with other Mimecast products easy for users to understand Mimecast security alerts

Cons

configuring some of the policies can be confusing occasional feature overlap some SPAM email will still get through unless you set very strict filters

### "MimeCast - Great Email Protection"

March 15, 2019

5.0

Experience has been great. We have great threat protection, URL scanning, Spam protection, Impersonation & Spoofing protection, appended disclaimers, etc. the list goes on. It all just works and all our accounts authenticate against Active Directory (Azure App). Support is much better than most our other vendors.

Pros

It was very easy to setup and administration is a breeze. Support is always available and very helpful.

Cons

Nothing I really dislike about this software.

July 31, 2020

5.0

Pros

Mimecast provides email security at my company - it is effective at screening spam emails and generally I find it easy to use to review filter/held emails which may be suspicious

### "Decent Email Security product"

August 18, 2020

5.0

It's good product compared to the price hence a good investment

Pros

The product is very easy to configure and provide good level of protection against phishing and other email based malware.

Cons

It's still an upcoming product and can use some upgrade when it comes to detection engine. Some emails were missed but overall detection is good.

Email security is a very important tool need to be in every organization In these days we are experiencing many cyber attacks mainly by compromising the user accounts

Pros

### "Solid email security product"

March 9, 2021

5.0

Overall it's a solid product, does its job well, and I would recommend it.

Pros

MimeCast Email Security makes it easy for us to mitigate email-based security threats and users generally tend to not notice it's even there, which is the best we could ask for.

Cons

It can slow down delivery sometimes, which usually isn't a big issue but can be an annoyance for workers and create spikes in support tickets.

### "Good Outlook Security"

April 5, 2019

3.0

Mimecast helps protect our business from phishing and other malicious emails.

Pros

The Outlook add-on makes it easy to monitor on-hold emails and release, permit or block individual emails and addresses. Mimecast also sends you daily emails letting you know which emails are on hold.

Cons

In a lot of cases junk email makes its way through the filter, while legitimate emails may be held.

### "Mimecast help with Email Traffic"

September 3, 2019

4.0

Helps with time management and weeding out users you do not want to receive emails from.

Pros

I like that 95% of emails that get stopped by Mimecast are worthless. Saves a lot of time and helps clean up spam coming in.

Cons

Occasionally, internal emails sent internally to all get hung up in here. Does not always make sense why.

### "very tight security"

June 28, 2018

Protects my email

Pros

It definitely protects my emails very well and it notifies me when an email or sender was blocked due to being unfamiliar

Cons

sometimes the emails get stuck in the cloud and you can't find it. The emails blocked but it can't be found. Sometimes the security is a little too tight

### "So you want to get rid of all the junk coming into your email server?"

June 27, 2017

5.0

Pros

Spoofs, wanncry, spear phishing to the CFO, AP clerks. Its a legitimate concern. We looked at proofpoint, but the minimum head count for licensing was 350. In comes mimecast. They focus on the emerging small and medium businesses who are not fortune 500 (though PP does protect half of the fortune 500) and the software does a fantastic job. Its quite literally just an MX record change to get on board.

Cons

Honestly, I've not found anything yet. Thus far its been perfect. I'm working through a small .msi deployment issue of the outlook toolbar addon, but that's about it.

### "MimeCast"

September 21, 2018

4.0

It works, it's easy and its reliable!

Pros

It is an effective alternative for sending large files via email. I like that it gives me the option to password protect.

Cons

That I constantly need to be integrating it to my outlook and maybe the instructions sent to the recipient could be more visibly appealing. I don't like that it limits access to 30 days only instead of being able to customize the time frame.

Suspicious emails can be blocked automatically without any prior intervention these files are easily release if need be and allowed in the future

Pros

Automatic email filtering and blocking to stop most unwanted emails which you can release yourself if you want them to come through

Cons

Like all types of online protection some stuff does make it through but you can add these to your black list and carry on

### "Mimecast Review"

February 23, 2021

4.0

So far this product has really cleaned up my inbox.

Pros

I like how this product finds spam and gives me the option to permanently block so that I don't have to manually unsubscribe and delete emails.

Cons

Sometimes this product holds up emails that are not harmful, which could eventually pose a problem if I am under a timetable.
