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

"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."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution's voice services work well for our company."
"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."
"The solution is inexpensive which is its main benefit."
"The solution has a very good log-in to the UI when compared to other solutions."
"IceWarp has multiple applications that are easy to use for many people."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"ProtonMail is cost-effective for encrypted mailing, offering extensive features and customization, especially if you want to provide your own hashing and keys."
"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

"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"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."
"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
"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."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"The database query for creating new database and querying about activities are too simplistic."
"Our customers sometimes have problems receiving mail."
"Customer service is not always helpful."
"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email."
"I think it is good but I feel that only tech-savvy people use ProtonMail. It is not that popular among other people."
 

Pricing and Cost Advice

"The license is based on the number of users."
"There are various licensing plans available based on geographic zone."
"Our licensing is on a yearly basis. There were no additional costs."
"It is definitely one of the lowest price solutions."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Pricing and licensing is very competitive and in some cases, cheap."
"The solution is inexpensive which is its main benefit."
"Costs far less than other solutions."
