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.

Trust and anonymity play a key role in secure communications
I am uncertain about the two-factor authentication feature. I have had integrations with other Proton services and have used Proton VPN once, though it has limited features. Simple Mail, which was acquired by ProtonMail, has been very useful for me. The pricing is moderate. I have not used any paid services from ProtonMail. It is not very costly, but I have not used any premium services. I am a customer of ProtonMail. I would rate ProtonMail an eight out of ten due to their transparency and the utility of their simple login feature. My job and company name should remain hidden.

Quotes from Members

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

Pros

"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."
"It's scalable and stable."
"It has great communication capabilities for team chatting and web conferences."
"The solution has a very good log-in to the UI when compared to other solutions."
"An effective, functional, very good tool for controlling resources."
"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."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The groupware module is the most valuable feature."
"The auto encryption of attachments is valuable."
"What I appreciate most about ProtonMail is that they are trusted, which is why I choose them."
 

Cons

"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."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"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 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."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"Our customers sometimes have problems receiving mail."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"I think it is good but I feel that only tech-savvy people use ProtonMail. It is not that popular among other people."
"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email."
 

Pricing and Cost Advice

"The license is based on the number of users."
"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."
"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."
"The solution is priced well."
"Our licensing is on a yearly basis. There were no additional costs."
"Pricing and licensing is very competitive and in some cases, cheap."
