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

"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"Go for it! I think it's an excellent product with great technical support."
"If you have a small to medium business and you require a professional collaboration server that focuses on the main services of emails and calendar scheduling, I recommend IceWarp."
"IceWarp offers very extended cross-platform communication solutions."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"It's scalable and stable."
"It has great communication capabilities for team chatting and web conferences."
"An effective, functional, very good tool for controlling resources at a low cost."
"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."
"As the license of our company is very affordable per year and per user, and considering the almost-zero administration needs, I would say that the cost is returned in the first three months, compared to other solutions."
 

Cons

"I am not satisfied with Clearswift because of the lack of customer support."
"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The Exchange compatibility mode is rather limited."
"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 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."
"Support is not good and it is challenging to receive a timely response."
"Customer service is not always helpful."
"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
 

Pricing and Cost Advice

Information not available
"The license is based on the number of users."
"There are various licensing plans available based on geographic zone."
"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 priced well."
"Pricing and licensing is very competitive and in some cases, cheap."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Our licensing is on a yearly basis. There were no additional costs."
"Costs far less than other solutions."
