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.

Block significant threats with enhanced phishing prevention
In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage. A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently. Security is a major feature where email security tools like Mimecast have delivered value by identifying and preventing phishing emails.

Quotes from Members

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

Pros

"The groupware module is the most valuable feature."
"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 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."
"It has great communication capabilities for team chatting and web conferences."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"It's scalable and stable."
"The solution has a very good log-in to the UI when compared to other solutions."
"The initial setup is very straightforward."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"It's good, it keeps the spam out."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"It offers an easy initial setup."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"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."
"I would rate Mimecast Email Security a nine out of ten."
 

Cons

"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."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Our customers sometimes have problems receiving mail."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"While it's quick and easy, the initial setup could be more user-friendly."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"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."
"I'd like to have better support from the product in the future."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Its pricing can be improved. It is a bit expensive."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"The solution is very expensive."
 

Pricing and Cost Advice

"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"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."
"Our licensing is on a yearly basis. There were no additional costs."
"Pricing and licensing is very competitive and in some cases, cheap."
"It is definitely one of the lowest price solutions."
"The solution is inexpensive which is its main benefit."
"It's an expensive solution."
"The product has good pricing in terms of return on investment."
"The customers can select the license packages as per their requirements."
"We pay monthly fees to our provider."
"It is a bit expensive."
"The licensing costs are per-user for the product that you get with them."
"For what it is, the product is overpriced."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
