Used to address improving our spam detection at a mail gateway level (not API driven)
  • Deliver mail
  • Reduce spam in inbox
  • Clear digest reports
  • Easy admin console for security team
  • Mail delivery speeds
  • Processing time for sandbox
  • Better support team
Well suited for organisations that plug in additional email software at an O365 level. Spam filtering is not O365 API driven like most modern tech.

We use Mimecast Secure Email Gateway to control spam, block unwanted viruses, send/receive large files, send/receive secure emails and utilize it for user awareness training.
  • Provides secure email transactions.
  • Ability to send and receive very large files.
  • Blocks a large amount of unwanted spam and dangerous files.
  • Allows to train users about bad email actors.
  • Web filtering and blocking.
  • The new updated portal when released was very difficult to use.
  • The customer support via phone is not always on par.
  • Email support when used could be a bit quicker when responding.
  • CyberGraph implementation is taking too long.
  • Feature requests should not take that long to complete.
Mimecast Secure Email Gateway is well suited for very large companies that need to control spam, unwanted attachments, Etc.
I would say it would be less appropriate for smaller companies as the cost may not be a good fit.

As our primary protection gateway for all incoming and outgoing email against current and next gen threats. Increased levels of phishing, weaponized links, attachments, nested documents and social engineering attempts make this an essential toolbox for our business.

Added to the feature-set of Large file send and additional optional addon's you really get what you pay for!
  • Anti Spam
  • Anti Phishing
  • URL Protection
  • Attachment Management
  • Anti Spoofing
  • User Awareness
  • Secure Transmission of Large or/and Sensitive Files
  • Admin Complexity is High - To Fine Tune Features you need to invest in training or high level support
  • Flexibility in delivery could be better, some solutions are on or off
  • Cost is high and inflexible when it comes to trying out new features
On an established email domain where malicious or spam email is a significant percentage it works well - but if you have admin in the background using it as a live tool assessing and fine tuning it in the background. Leaving end users to manage held mail isn't always the best solution.

Works well in terms of end user experience with the Outlook plugin ideally with SSO enabled (so they don't have to remember to keep logged into it if their pw changes). The web plugin is less detailed and feature rich.

The Benefits of Mimecast

Mimecast is used across our whole organization. It serves as our email archiving system as well as our spam filter. It is also a great tool for catching phishing emails before they get to our end users. Mimecast also allows us to send large files, basically serving as a dropbox but cutting out the step of uploading the files.
  • 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.
Mimecast Secure Email Gateway is great for searching for previous emails. It allows you to get very granular and create a very specific search to easily find the email you are looking for. It also makes it easy to save all emails, without having to go through an archiving process. You can also set Mimecast to save emails for x number of years and therefore remove all emails older than that period.

Mimecast Secure Email Gateway is being used across our entire organization for e-mail security. The security solution covers both desktop and mobile clients. Being in the defense industry, a lot of very sensitive information is transmitted via e-mail, and to ensure that this is securely done is very important. Protection against unsafe links and phishing is another key problem that Mimecast solves.
  • 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.
The software is well suited to large corporate organizations with a high volume of emails sent each day within, and out of, the organization. Another good fit is in organizations where communication does not take place in the public domain, but rather contains confidential information. Organizations, where a phishing attack could be of greater significance than in non-defense related industries, are also a big market.

Mimecast is not well suited to smaller businesses in which communication volume is low, and the staff is very technically savvy. These staff can typically ascertain the safety of e-mail content themselves and speed up their working experience.

We switched to Mimecast Secure Email Gateway for our entire organization three years ago when our former provider discontinued the product we were using. It was a great upgrade for us! Mimecast does an excellent job of filtering spam and other unwanted messages. It also provides a lot of control in terms of the ability to modify rules, make exceptions, and search to find what happened to an email message. Furthermore, Mimecast offers additional security features which protect our users from threats. For example, Mimecast rewrites the URLs in all incoming messages and checks those when a user clicks to block malicious URLs.
  • 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.
In my opinion, Mimecast is suitable for any business that wants greater control over the content, URLs, and attachments they receive via email. It also serves a great business continuity function, given the business-critical nature of email communication today. We have been very pleased with the value of our investment in Mimecast's services and would sign up again in a heartbeat if we had it to do all over.

Mimecast is used by our entire organization for our business continuity plan as well as our production email security. We added the email threat management package to our original subscription in 2017. We license each user and use it in conjunction with high availability Exchange on prem and SMSMSE for antivirus.
  • 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.
For companies with larger IT departments, especially someone Exchange savvy, Mimecast is a great tool that works terrific after you set it up. Administering and managing it is easy once it's up. The initial setup of any rules or functionality is overly complicated and takes great patience and lots of support time to accomplish what you want. The ability to use the Mimecast app or website during our onsite Exchange maintenance periods is terrific and it works great for business continuity.

We implemented Mimecast as an extra layer of protection in our cyber security plan. We opted to implement company-wide to ensure all departments were protected.

When we were first shown the platform we were only looking for a solution to replace our then current automatic disclaimer, however, we soon realised it was much more than this. The disclaimer option was just one feature of a security gateway platform.
  • URL Protection - Mimecast filters and checks every URL which allows a double check for malicious links. Each link is re-directed through the Mimecast platform and if it is malicious the user is prohibited from accessing it. Occasionally it will ask the user to decide whether the link is clean or not to help train user awareness. I find this very helpful in reducing downtime from false links.
  • Attachment Protection - alongside filtering URLs Mimecast also checks all attachments for malicious code and other undesirable content. If it identifies something that doesn't look right it will hold the email and notify the user. If it is an expected email, it can be released to a sandbox to verify the contents. We have found this very useful in preventing phishing attacks through malicious code sent in word documents.
  • Bounced & Rejected mail - Mimecast employs a host of different filters and rules for mail traffic. Should mail meet certain criteria it either bounces or is rejected. This can be for many reasons. Impersonation is a classical and very useful filter which rejects phishing mail from people trying to impersonate individual users. Following implementation, we have seen a vast reduction in mail purporting to be from us sent to us.
  • Held mail - this is a form of junk mail filtering. When an email is identified by Mimecast as potential junk or spam it will hold the email in the queue and send a notification email to the user allowing them to block, allow, or release. If you release the email it will allow you to receive that specific email but hold all future emails from the sender until you select allow. This has helped to dramatically reduce spam and junk email entering our system.
  • Mimecast also applies an automatic disclaimer to all outbound email. There is a lot of functionality which allows for different disclaimers to be used for different domains or departments etc. This flexibility is very useful for us as it enables us to use one system for multiple domains and departments.
  • Designing the disclaimers is a little bit difficult as it requires advanced HTML knowledge. Currently, there isn't a visual editor just a preview page which displays the HTML content. It would be very good if they could add this functionality in the future.
I would say Mimecast is well suited to most organisations - the bigger the more important. That said, even small organisations need to protect themselves and Mimecast is a fantastic offering. I can honestly vouch it is the market leader in providing a secure email gateway.

Mimecast is being used across the whole organization to provide protection against spam, malware and phishing attempts. We also utilize the Attachment and URL protections to bring an added layer of security to our end users. Mimecast addressed issues that we could not have thought of in regards to Whaling and Impersonation attempts.
  • Stops spam messages based on it's vast known bad and reputation lists
  • Easy to find where a problem exists in the chain of getting an email through it's tracking area
  • Fairly easy to configure and setup with the very nicely provided guides and videos
  • We've found that the console will timeout frequently when trying to search for various things or look at different sections of the console
  • We have a hard time getting into support without waiting for at least a half hour or more
We think that any organization that is looking to have a flexible and not overly complex email gateway should consider Mimecast. It was an fairly simple cut-over and the implementation team was helpful. With that said you may find support a little lacking. You will spend a little more, however, you get what you pay for.
