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."

"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."

"The solution's voice services work well for our company."

"The groupware module is the most valuable feature."

"An effective, functional, very good tool for controlling resources."

"Its price is the most valuable. It is definitely one of the lowest price solutions."

"IceWarp has multiple applications that are easy to use for many people."

"The solution is easy to manage and includes features such as smart documents and the archiving of user data."

More IceWarp pros

"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."

"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."

"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."

"We like the content filtering and secure messaging features."

"I recommend Mimecast based on customer requirements and budget."

"Email security is the most valuable feature of the solution."

"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."

"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."

More Mimecast Email and Collaboration Threat Protection pros

Cons

"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."

"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."

"Support should be improved. Most of the time, the queries are not resolved within the SLA."

"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."

"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."

"The solution needs improvements in security, particularly regarding document management."

"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."

"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."

More IceWarp cons

"The price of the solution is expensive. It can improve by reducing the price."

"The filtering needs more flexibility."

"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."

"The interface isn't the best. How everything works on the back end is confusing."

"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."

"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."

"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."

"We discussed the phishing aspect, the DNS system, and the key rotation."

Pricing and Cost Advice

"There are various licensing plans available based on geographic zone."

"I would rate the pricing and eight out of ten."

"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."

"Costs far less than other solutions."

"Pricing and licensing is very competitive and in some cases, cheap."

"Our licensing is on a yearly basis. There were no additional costs."

"The license is based on the number of users."

"It is definitely one of the lowest price solutions."

More IceWarp pricing and cost advice

"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."

"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."

"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."

"It's an expensive solution."

"The price of Mimecast Mailbox Continuity is expensive."

"I'm always going to say the price needs to be lower, but it's reasonable."

"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
