We have HIPAA in the United States. This is, basically, a patient privacy protocol. We have to stay compliant with HIPAA. Therefore, we have to monitor the content of the mail, both in and out, on a very basic level to make sure that it doesn't give outpatient information. This product has a built-in HIPAA dictionary, So that it will automatically scan inbound and outbound emails, based on a set of parameters that we feed into the system. It will stop anything it thinks might be a problem. It will let us know, and then we can review the mail and release it or reject it as needed. That's extremely important for us so that personal health identification information doesn't get out there for any patients.
We also use it to track messaging. If someone says, "I didn't get a message," we can confirm or deny that based on what we see.
We use URL protection inside emails so it will potentially block what it thinks is a bad URL. Those are often false positives. However, it's better safe than sorry.
We do all our spam filtering through it so that it will block any spam. If it's on the borderline, it will let the user know and ask them if this is a legit email; however, mostly, it's just blocking things, and we review. A couple of times every day, we'll look just to see if anything's getting held there that shouldn't be.
We use the tool for email security. It filters email messages for spam and phishing and provides overall security functions.

View full review »I am an investment research analyst. We use this solution for spam and as our security filter.
View full review »The solution is primarily used to stop malicious emails with malicious attachments and can stop users from accessing sites or links that have a virus or malicious content.
View full review »It is our spam filter, phishing filter, and executive impersonation filter. We have its latest version.
View full review »Mimecast security in general, it's a SaaS service so they have their servers; they have everything on their side and we're just quote-unquote, passing the traffic through them, the email traffic through them.
Mimecast has multiple different solutions, all linked to the email. They recently added user info security training, but we're not using that. We, however, are using the archive piece and we're currently using their security threat protection. Regarding the threat protection — that does just fine. As far as the security goes — they had a big hiccup earlier this year where they were giving a false positive to a bunch of attachments. I'm not sure what happened on their side but for one week at least we had that issue. It took them a little over a week to resolve the issue. We also had some minor incidents after that, that they resolved.
Generally speaking, other than that event, it has been good. It doesn't block a hundred percent of the security threats received, but you have a lot of options to tag or even further analyze the messages received through Mimecast, either to a third-party solution or through an endpoint solution.
Everyone uses this solution at our company, whether they know it or not because you can leave it as transparent as you want it, or as user-demanding as you want it. There are specific items that only IT uses, but in general, this solution is used by one hundred percent of the company.
