  • Less than intuitive admin console. I've found a few things to be difficult to understand and implement.
  • There are A LOT of features that can be implemented. It's hard to decipher which ones should or shouldn't be implemented.

  • Sandboxing incoming attachments, instead of opening directly on your computer.
  • Scanning links in emails for websites that could harm the organization
  • Keeping SPAM out of users email boxes and increasing efficiencies by reducing the number of emails a user has to wade through.
  • Archiving all emails so if a use deletes something they can go back to the archive and retrieve an old email.
  • There is a lot to learn to be good with Mimecast and it can be confusing at times
  • It is easy for a user to Whitelist a email address or domain, but cumbersome to do it for the organization
  • They have made many changes to the interface to make it easier to navigate, but sometimes it still is not intuitive where you need to go.

  • Catches spam and phishing emails
  • Saves and archives all emails for the designated period
  • Sends large files that are too big for Outlook to handle
  • It has a great search feature for finding old emails.
  • Phishing scams are getting more and more sophisticated so it could always improve on catching phishing emails.

  • Allows you as the user to not expose your SMTP gateway to the internet. All emails go to Mimecast and you just need to allow SMTP traffic from Mimecast only.
  • Very reliable in up time with rarely an issue receiving or sending mail through it.
  • They have limited electronic resources available for support. It is rare that I find the answer to an issue without having to call them.
  • They are frequently emailing in an attempt to sell extra services...which can be annoying.

  • Sandbox filtering of mail attachments is great, and we are alerted to caught items.
  • Greymail tagging is useful to some employees.
  • There have been issues of downtime or slow delivery, but we have not lost any mail.
  • The initial setup is a bit counter-intuitive.

  • Standing up an exact 1:1 copy of email inboxes for DR purposes.
  • Scanning any incoming email to be filtered for spam/threats.
  • Automatically encrypting all outgoing email.
  • Email filtering can be hit or miss. Will incorrectly filter out emails that will go noticed by end-users.
  • Admin web UI can be confusing and not so intuitive.
  • Inability to release incorrectly filtered messages to the end-user mailbox.

  • Runs relatively unnoticed in the background, not interfering with daily tasks.
  • Has a very powerful search feature.
  • Has a very intuitive management console for users to manage blocked addresses, their online inbox, and various other configuration settings.
  • Requires each device used with it to be enrolled to open links. This enrollment is removed every time cache is clear.
  • Links that are opened in e-mails are first scanned, and then the user is asked to confirm that they think the link is safe, and then only do you possibly get access to where the link is pointing.
  • Sometimes Mimecast will place e-mails on hold, without sending a notification, resulting in delayed delivery. This can be avoided by working within the online mailbox and keeping a look-out for held mails.

  • Excellent filtering of spam and unwanted messages. It really cleans things up in this regard without producing a lot of false positives.
  • It has great security features that enable us to protect our users from email borne threats.
  • Powerful configuration options that help you to dial in exactly how you want Mimecast to behave.
  • A great Outlook add-in for users that is simple and convenient.
  • Mimecast offers the ability to spool mail if your mail server is down. Users can access this spooled mail for business continuity.
  • The admin console is powerful, but it isn't always intuitive. It seems like things could be a little better organized to make it easier for admins to use.
  • The impersonation protection rule is good and keeps getting better, but could still use work.

  • Mimecast really minimizes Spam distraction by providing an hourly or daily digest (time length is fully customizable) of questionable emails. Now, our users only have to monitor those occassionally, and can train the system to prevent spam in the future.
  • Mimecast's sandbox can analyze any questionable email and prevent it from ever getting delivered or executed by our users.
  • The software prevents any malicious links from getting through and even obfuscates to real link until it is proven safe.
  • While the daily or hourly digest of spam/questionable emails is very useful, it does make it easy for users to forever block senders - which they may actually needd those emails in the future. Providing a link to the management console with blocking may be a better option - training the user how to unblock and use the more sophisticated management console.

  • Filters spam well. About 66% of our email is rejected and never hits user Outlook Mailboxes. There are very few times when a legitimate email is blocked.
  • Catches malware-laden attachments. Mimecast catches the vast majority of these.
  • Filters and blocks dangerous links embedded in email. Mimecast blocks almost all of these.
  • The Outlook plugin is intuitive and works well.
  • Has been extremely reliable. Virtually no down time.
  • The user interface could be a little more intuitive on the admin side.
  • Sometimes response times for accessing features via the Outlook features is slow
  • Proper configuration to optimize filtering can require quite a bit of tweaking.

  • Mimecast has a great spam engine, and great controls to permit, deny or release spam it puts on hold.
  • Mimecast does a great job of preventing impersonation and phishing attacks.
  • Mimecast does a great job of providing failover Outlook connectivity if our on premise Exchange server is down.
  • Mimecast administration is complicated, I wish the admin console and policies were more intuitive.
  • I wish Mimecast error messages were more granular, you get the same error message for multiple issues.
  • Other than those two minor issues, Mimecast is great.

  • Impersonation Detection - We've received a lot of fake CEO emails recently. The previous product we had had limited ability to detect this. Mimecast on the other hand can use multiple factors to help determine whether an email from outside the organization is impersonating an employee.
  • It allows you to customize rules for specific people or groups
  • It has a lot more features
  • The web interface, while powerful, can be counter intuitive to use. If you're not in there all the time and very familiar with how it works, often you will have to reach out to support to remind you how to get something done
  • The email support is just okay. I would be very frustrated if I didn't opt for the option for phone support.

  • Mimecast is fantastic as a spam blocker. Our users get the traditional noon day email with their "held" items for release at their discretion, but we have a small rate of failure for recognizing true spam vs. true emails.
  • It is extremely easy for the users to use, especially with the Outlook ribbon feature enabled so that they can access their held (spam) emails, allowed senders list (white list), blocked senders list (blacklist) and other features quickly.
  • We have experienced a few outages or maintenance windows internally for our on prem email system, but we have not had Mimecast unavailable for us once. It's been 100% reliable.
  • The Admin Management console is absurdly complicated. For every first time we wanted to setup we've had to call their support for assistance. Support is quick and fantastic but it's so difficult to do anything yourself. They seem to have gone out of their way to call features unique things instead of using standard language from other providers so you as an IT professional know what you're looking for to setup.
  • They have lots of KB articles, which their support will point you to. They are written on the most basic level and don't actually provide the help you need. For example, the KB page will tell you the list of options on the page... but not actually tell you what you do, why you might use them, or define their terminology.
  • Their email threat management system has several nice features. One of the features available is that it will rewrite links in emails so that users click the link and it sandboxes the link, testing it on their server space and the user sees it there. This means the actual link in the email gets changed to the address of one of their servers. As a law firm, the EXACT LINKS are important to maintain in our communications and editing actual data from our clients to point to a Mimecast server is an unacceptable practice. I wish they had an alternative that did not edit the link itself on the page.

  • Spam detection - Mimecast does a great job of filtering spam and giving admins and users control over the sensitivity of the spam filter.
  • Email security - we love how Mimecast detects and removes malicious attachments.
  • URL & link security - all URLs within emails are scanned and re-written so that when users click on links, they are first checked for security and blocked if the destination is malicious.
  • Data loss prevention - Mimecast does a good job of scanning outgoing email for sensitive content.
  • Admin interface is a little clunky but slowly improving.
  • Methodology - their approach to policies and rules is a little different from other products. It can take a little bit of time to "think like Mimecast" when setting up your environment.
  • Control - some policies and scanning sensitivity give you a lot of control, other areas could be better.

  • Filtering of spam, viruses and fraudulent emails
  • Mail Archival (going forward from the time of install only)
  • Account Managment
  • Integration with Outlook and Active directory
  • User friendly client interface
  • Mimecast contract has an autorenew clause, if you don't notify them by the given date that you plan on canceling service you will be locked in to paying for another year.
  • It is very very very hard to export your archived data in a format that can be used should you need to.
  • Mimecast charges to ingest emails from before the date of service. The prices are very high.

  • Allows you to customize rule sets for specific individuals, groups, or all staff
  • Good support and an engaging user base that offers questions and solutions to issues
  • The web portal for end users could be a bit more UI friendly
  • Getting a message to pass through the Mimecast policies can be a bit long sometimes depending on how many policies are applied
