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

"The solution has a very good log-in to the UI when compared to other solutions."
"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's voice services work well for our company."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"An effective, functional, very good tool for controlling resources."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"IceWarp has multiple applications that are easy to use for many people."
"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."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"I would rate Mimecast Email Security a nine out of ten."
"It offers an easy initial setup."
"The solution offers good technical support."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"The setup was easy."
"The solution's performance is good."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
 

Cons

"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"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."
"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 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."
"Our customers sometimes have problems receiving mail."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"External security features need improvement."
"The feature that should be included is to remove the block on the encrypted files."
"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 system is not user-friendly because you have to create policies that are mapped in a dictionary."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"I'd like to have better support from the product in the future."
 

Pricing and Cost Advice

"Our licensing is on a yearly basis. There were no additional costs."
"Pricing and licensing is very competitive and in some cases, cheap."
"There are various licensing plans available based on geographic zone."
"I would rate the pricing and eight out of ten."
"The solution is priced well."
"It is definitely one of the lowest price solutions."
"Costs far less than other solutions."
"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."
"We pay monthly fees to our provider."
"The product price is moderate. I rate the pricing a five out of ten."
"The customers can select the license packages as per their requirements."
"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."
"It's an expensive solution."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
