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

"IceWarp has multiple applications that are easy to use for many people."
"The solution has a very good log-in to the UI when compared to other solutions."
"IceWarp offers very extended cross-platform communication solutions."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"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."
"The solution's voice services work well for our company."
"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's scalable and stable."
"The auto encryption of attachments is valuable."
"What I appreciate most about ProtonMail is that they are trusted, which is why I choose them."
"ProtonMail is cost-effective for encrypted mailing, offering extensive features and customization, especially if you want to provide your own hashing and keys."
 

Cons

"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 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."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"Support is not good and it is challenging to receive a timely response."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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."
"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

"There are various licensing plans available based on geographic zone."
"Costs far less than other solutions."
"The solution is inexpensive which is its main benefit."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"It is definitely one of the lowest price 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."
