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.

A simple and easy-to-handle solution that does not need multiple configurations, but its pricing could be improved
Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations. A single IT admin supporting over 100 or 200 users can easily understand everyday reports. Trustifi Inbound Shield is a user-friendly solution that even simple lay people can understand. The product helps our customers avoid 95% of unwanted phishing emails.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"Mimecast certainly helped my customers reduce phishing emails."
"The integration is straightforward."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"We like the content filtering and secure messaging features."
"The solution's performance is good."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"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."
"The installation is not so straightforward."
"They could provide a unified licensing model, including all the security features."
"External security features need improvement."
"Its pricing can be improved. It is a bit expensive."
"I'd like to have better support from the product in the future."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The customers can select the license packages as per their requirements."
"We pay monthly fees to our provider."
"The product has good pricing in terms of return on investment."
"The licensing costs are per-user for the product that you get with them."
"It's an expensive solution."
"The solution is expensive."
