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