Secure communications that prompts responses with room for improved user interface
I primarily value HCL Notes for its security features. The software's secure communication is particularly useful when dealing with professional entities. It ensures that business is conducted smoothly, allowing me to use my organization's email confidently, as opposed to my personal Gmail, which might not prompt responses from some entities.

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 solution provides great security."
"The most valuable feature is the UI."
"The most valuable feature is security. It's very easy to manage security on records, views, and tables."
"The solution is practical, good interface, and performs well."
"The most valuable feature is the access that it provides to documents. This offers us an easy way to make changes."
"Notes is a perfectly adequate front end. It's clear and straightforward."
"HCL Notes is stable most of the time."
"The product is very stable and scalable."
"What I appreciate most about ProtonMail is that they are trusted, which is why I choose them."
"The auto encryption of attachments is valuable."
 

Cons

"GUI and replication can be improved."
"I love this product. I have used it for many years, and I have been a developer for it. If anything, it can be faster in the client version. The client version is a little bit hard. It is not fast. This is the only problem I see. Otherwise, it is a very good product."
"I would like to HCL update Notes' development tool and make it more attractive like Microsoft Visual Studio and similar products. For example, there's a programming language that I used for my product Woodpecker called LotusScript. LotusScript has been available since around 1995. When LotusScript was released, it was like the original Visual Basic, but it has improved since then."
"The interface could be more user-friendly. Some additional trainings could be added as well."
"Web support is very old and needs an upgrade. We can handle a different password for the client to access the mail services, compared to the web services. We need to implement many other components to get access to the web access. There could be a feature to interpret if the web access is available from any end-user equipment."
"There is a chat component but it does not work properly."
"Some people complain that they want something more modern and jazzy."
"The only improvement that we're planning to do is that all our applications are still designed in the layout and format of Notes version 4, and our plan over the coming years is to modernize their look. One of the things they're developing or considering deploying is a program to automatically upgrade the look and feel of databases. If they deploy that, that will be revolutionary. In other words, we decide on a corporate look and feel for our database and press a button. We've probably got 50 different applications in Notes, and it would just go through the whole lot and upgrade all of them to look the same."
"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 solution is expensive. There are many components or features which make the price very high."
"The price is reasonable."
"I don't remember how much we paid when we first bought the Domino license, but now, we pay only for the passport. For 30 client licenses, we pay about $1,500 per year, and we don't consider it very expensive for the quality of the product. In our case, we need 30 client licenses. So, we buy 30 client licenses independently of the server. It is very easy for us to choose and maintain this kind of license and get the passport advantage."
"We pay licensing fees on a yearly basis."
"It was reasonably priced, but the product itself was not worth the cost."
"We pay annually for the use of the solution."
"It is far cheaper to license. It is a third of the cost of our Microsoft license for 10 times the amount of usage. Developing applications cost a fraction of anything else. There are two reasons for that. First of all, applications are very fast to build. All the security is already built into the platform, so you don't have to worry about security at all. The other thing is that because fewer people use it than, for example, Microsoft SharePoint, the salary commanded by programmers is slightly lower. So, it is not only faster; you also get cheaper programmers. So, you really win-win-win on it."
