Accessible from any device, good support, and works very well for emails, document sharing, and workflows
What I like about this solution is that you can use it for mailing, as a client for email, and you can also use it for workflows. So, you can easily develop applications. Even people who haven't got great IT skills can develop some basic applications to use in the company, especially a workflow application. So, it is for mailing and for applications, which is a great thing about HCL Notes. It is very good for managing and sharing documents on the network or inside the company. It works very well for sharing documents. It is one of the best products in the world for workflow applications. It works very well for workflows or decisional processes where a task needs to be first approved by someone. After that, the task moves to the next or final stage where another person approves it with some notes or attached documents. People who are on the move outside the company but need to interact with the database of the company can do some tasks in the HCL Notes application offline. When they have connectivity, the information is updated or replicated in real-time. They can install the application on different devices. They can use it on mobile phones or iPad.

Quotes from Members

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

Pros

"The most valuable feature is security. It's very easy to manage security on records, views, and tables."
"Notes is a perfectly adequate front end. It's clear and straightforward."
"The initial setup was easy for me."
"The solution provides great security."
"The solution is practical, good interface, and performs well."
"Its security is absolutely stratospheric. In an application, you can lock down to field-level security. For example, I could log in and see a field in an HR database with salaries. When you log in, you see exactly the same database, but the field with the salary just isn't there. So, you can literally have field-level security on it, and you can also have secure encryption. For example, I could give you that database allowing you to see the salary, but a calculation that shows how much they get per month in another field is encrypted. So, you won't be able to see that because you don't have the encryption key. You can implement high-level security very simply."
"HCL Notes has fantastic built-in security. The email and personal communication components are excellent, but they are some applications provided by HCL that Notes previously provided when it was under IBM and Lotus. Everyone wants email, so that's just part of the product. However, more savvy users can build their own solutions for managing information, and that's the great thing about it."
"The most valuable feature is the access that it provides to documents. This offers us an easy way to make changes."
"The auto encryption of attachments is valuable."
 

Cons

"I would like to see integration with other solutions."
"The performance was terrible because we have a very large database with around three million records, including attachments and scanned comments. It was slow, and integrating new technologies or designs was also slow."
"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."
"It is a heavy program and uses more resources than an email client should."
"There is a chat component but it does not work properly."
"The solution could improve by adding some more features."
"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."
"The interface could be more user-friendly. Some additional trainings could be added as well."
"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."
"We pay annually for the use of the solution."
"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."
"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."
"We pay licensing fees on a yearly basis."
"It was reasonably priced, but the product itself was not worth the cost."
"The price is reasonable."
