Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"It has great communication capabilities for team chatting and web conferences."
"It's scalable and stable."
"The TeamChat feature has been really good for our email management. It lets us collaborate, share files, and invite guests like Google Spaces or Microsoft Teams. I like the two-factor authentication for security. However, they need to improve their document collaboration tools, as their Word, Excel, and PowerPoint features are basic compared to Microsoft and Google."
"The solution has a very good log-in to the UI when compared to other solutions."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"IceWarp has multiple applications that are easy to use for many people."
"The groupware module is the most valuable feature."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"It's good, it keeps the spam out."
"I recommend Mimecast based on customer requirements and budget."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"The initial setup is very straightforward."
"The product is good. To date, we have not faced any challenges."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"Mimecast has some good support services in place."
 

Cons

"The tool's configuration capabilities are not straightforward. Apart from that, if I want to archive emails into a vault so that they can be retrieved again later, the integration doesn't work, and IceWarp crashes."
"The exchange compatibility mode is rather limited. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"Our customers sometimes have problems receiving mail."
"The solution needs improvements in security, particularly regarding document management."
"The solution should improve the mailing list feature. Google has a similar feature where you can automate sending files to different people in a sequence, but that feature is no longer available in the current version of IceWarp. Other features may also have been removed in the current version."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."
"The price could be better, it should be reduced."
"The product's interface could be improved to be more user-friendly."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"The solution is expensive in comparison to similar solutions."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."
"Technical support has been slower than it was in the past, likely due to the pandemic."
 

Pricing and Cost Advice

"It is definitely one of the lowest price solutions."
"There are various licensing plans available based on geographic zone."
"The solution is priced well."
"I would rate the pricing and eight out of ten."
"The license is based on the number of users."
"The solution is inexpensive which is its main benefit."
"Pricing and licensing is very competitive and in some cases, cheap."
"I don't see any challenges for the Indian market. For example, 1 GB is available for around 399 INR, and 2 GB for 499 INR. They offer a range of plans, from basic to professional and enterprise, with multiple features. IceWarp's aggressive pricing is competitive compared to other market solutions like Zoho and Microsoft. One significant advantage is that IceWarp does not impose user capping like Google and Microsoft, which allows for substantial cost savings and flexibility in user conversion."
"The solution is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The product price is moderate. I rate the pricing a five out of ten."
"It is a bit expensive."
"For what it is, the product is overpriced."
"The customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"It's an expensive solution."
