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."
"IceWarp has multiple applications that are easy to use for many people."
"The groupware module is the most valuable feature."
"The solution has a very good log-in to the UI when compared to other solutions."
"The solution's voice services work well for our company."
"An effective, functional, very good tool for controlling resources."
"It's scalable and stable."
"It has great communication capabilities for team chatting and web conferences."
"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."
 

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"The solution needs improvements in security, particularly regarding document management."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"Our customers sometimes have problems receiving mail."
"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 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 it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"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."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
 

Pricing and Cost Advice

Information not available
"It is definitely one of the lowest price solutions."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"Our licensing is on a yearly basis. There were no additional costs."
"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 license is based on the number of users."
"Pricing and licensing is very competitive and in some cases, cheap."
"There are various licensing plans available based on geographic zone."
