    Robust Security with Effective Threat Detection

    Reviewed on Jun 12, 2026
    Review provided by G2
    What do you like best about the product?
    I like Mimecast Advanced Email Security for its consistently strong threat detection and the confidence it gives to our team. It catches phishing attempts, impersonation attacks, and malicious attachments with impressive accuracy. The URL rewriting and sandboxing features add an extra layer of protection that feels reliable. The platform integrates smoothly with Microsoft 365, and its policy control makes it easy to tailor security to our environment. It also offers a strong detection with high accuracy and low false positives and integrates easily with Outlook and Microsoft 365.
    What do you dislike about the product?
    While Mimecast Advanced Email Security is overall strong, there are a few areas that could be improved. The admin interface feels unintuitive, especially when navigating complex policy settings or searching through logs. Some features have a steeper learning curve than expected, and occasional false positives still require manual review. Reporting could be more streamlined and visually modern. These are not deal breakers, but they do add friction to day-to-day administration.
    What problems is the product solving and how is that benefiting you?
    I use Mimecast Advanced Email Security to block phishing, malware, and impersonation attacks. It reduces spam, improves inbox hygiene, and offers policy control over URLs and sender behavior, boosting our compliance with archiving and ediscovery tools.

    Email defenses have reduced phishing risk and support strong compliance and user awareness

    Reviewed on Jun 10, 2026
    Review from a verified AWS customer

    What is our primary use case?

    The primary use cases for Mimecast Advanced Email Security  is email security, which focuses on email inspection, phishing, and impersonation detection.

    What is most valuable?

    Feature-wise, what we normally see as a provider is how well they are aligned with their confidentiality management like DMARC, SPF, and DKIM management. Mimecast Advanced Email Security  has been doing an excellent job in that area, as well as the compliance part, including how they do email archival, legal holding, and eDiscovery . Apart from that, they also have features like awareness training and user risk scoring, which definitely helps as a provider to show the complete picture to end customers.

    Regarding pricing, Mimecast Advanced Email Security will be at par with Proofpoint. They are not saying they are very cheap; they are a decently premium product in the market. The ROI discussion sometimes wins the conversations. Pricing-wise, they are slightly premium, and that is how everyone has positioned themselves in the market.

    What needs improvement?

    The improvement needed is not necessarily in the product itself, but rather around how other organizations have evolved. The DLP  discussion is no longer limited to email; it has gone to border level with companies like Zscaler, Netskope , and Palo Alto giving the complete full-stack SASE  setup. When somebody has a SASE  setup, then Mimecast Advanced Email Security DLP  might not even be needed at a point in time. Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere.

    The second thing is when you buy an XDR  provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity. You get a holistic picture. When pushing Mimecast Advanced Email Security to end customers, people are more often saying that they would rather buy XDR  from another provider because the story when an analyst sees is complete in terms of what they see, whereas they only get an email story from Mimecast Advanced Email Security. Mimecast Advanced Email Security has to improve there. Companies like Abnormal AI cover more on UEBA  and user behavior, and there are many things for Mimecast Advanced Email Security to improve in this area as well.

    It is less of a technology issue; they are doing very well on email. The conversation for them to have is on how to get into a broader level or how to get a tie-up to become a broader supplier. At least from a service provider landscape, I can say that.

    For how long have I used the solution?

    I have been working with Mimecast Advanced Email Security for probably three to five years.

    What do I think about the stability of the solution?

    Mimecast Advanced Email Security is a good product and is very stable.

    What do I think about the scalability of the solution?

    Mimecast Advanced Email Security is definitely scalable, and we are deploying it in very large environments.

    How are customer service and support?

    The customer service is good. Normally as a service provider, we do have our in-house support and we manage most of the things in-house, but if we need help, they are great. They are not like Microsoft, but they are great at it. They respond properly and try to help wherever they can.

    How was the initial setup?

    The setup is straightforward.

    What about the implementation team?

    We do in-house deployment.

    What was our ROI?

    The ROI is more around whether they are able to reduce the risk dramatically. The ROI which companies see should be able to justify buying Mimecast Advanced Email Security. It is acceptable. I cannot say that it is cheaper, but definitely it is on a decent side. People can buy it. It is not very costly. The ROI is decent and they can definitely invest in it.

    What other advice do I have?

    DLP is part of most of the compliance journey for most organizations because it helps identify the PII data which normally gets sent. Sometimes you have to send it, and you have no other choice than the option of masking the data. It is this kind of a filter where you have an option to identify whether there are any passport details, customer PII data, or any source code. You have an option to hold it or encrypt it if you need to. If you still have to send it, you can encrypt and send it. You can notify your security team to check it and all that. These are features which most DLP has, and even Proofpoint has similar features.

    They are being pretty happy with Mimecast Advanced Email Security. The policies are decently researched and marked. They are happy and at the same time, with some of the features, they have the option to customize. That is where service providers like us come into the picture. We help them customize few of the policies, but apart from that, they have been very strong in terms of the policies and their processes.

    It will be straightforward. Since you have email security, you get a decent number of emails without phishing and BEC risk. They reduce dramatically. Email availability and business communication continue uninterrupted, so you have email continuity in your picture. Compliance, as I mentioned, the litigation hold and eDiscovery  helps them maintain compliance. I have seen that being utilized by a few of our legal clients. For them, it is very useful. Data leakage is reduced; if you have an option to block something, encrypt it, mask it, or block it, you have less risk of data leakage. User security awareness is also important. They do have phishing simulation and security awareness trainings that help reduce human errors and maintain user risk scores.

    The primary thing which comes when I suggest is that people mostly go for email security features. I would still recommend people to start with their DMARC analyzer. Start from there, start your authentication, get the authentication methodology right, get the process right, and then followed by taking a product like Mimecast Advanced Email Security. I have been in this field for ten years, and in Microland, I have been for three years. Overall, I would give this product a rating of eight point five.

    Reliable, Intuitive Spam Filtering with Strong Weblink Protection

    Reviewed on Apr 07, 2026
    Review provided by G2
    What do you like best about the product?
    I appreciate the intuitive spam filtering - this greatly reduces the junk mail in my inbox. The spam filter is reliable, and I receive a reminder email each day that I still have messages "on hold" in moderation.

    I am glad there is an automated feature that allows me to block senders or domains, but also allows me to permit senders or domains. This is very helpful to reduce the time I spend moderating emails.

    Another feature I really like is the protection with weblinks. The security with the weblinks also integrates with Teams, so I know I am covered in both Outlook and Teams.
    What do you dislike about the product?
    One downside is the time it takes to receive security codes for weblinks.
    What problems is the product solving and how is that benefiting you?
    Mimecast keeps up with the bots and scammers by outsmarting them. It has helped protect me from phishing attempts, and it saves me time by filtering out spam.
