Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

Provides strong data protection with virtual patching and vulnerability assessments

Cons

"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The platform's cost-effectiveness could be improved."
"While it's quick and easy, the initial setup could be more user-friendly."

"The tool can be challenging because it relies on rule-based configurations, especially for addressing impersonation threats. This approach requires setting up numerous rules to ensure filtering. It should work based on behavior-based analytics."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"The solution needs better support."
"The solution must provide features to scan QR codes for threats."
"If they want to be the primary or best solution, they need to have better email management features."
"The solution is not easy to set up. However, we have employees that have the knowledge that can do the difficult implementation. It would be better if the process was easier."
"The custom tailoring is limited."
"I would like to see this solution become more flexible."
"In general, our company should make the tool more robust to protect our systems."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
