Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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.

Quotes from Members

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

Pros

"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"The solution's voice services work well for our company."
"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."
"It has great communication capabilities for team chatting and web conferences."
"An effective, functional, very good tool for controlling resources."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"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."
"IceWarp has multiple applications that are easy to use for many people."
"The solution has a very good log-in to the UI when compared to other solutions."
 

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The solution needs improvements in security, particularly regarding document management."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"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."
