Has improved email security through built-in encryption and supported offline work effectively
We don't use team workspace with HCL Notes; we use only Microsoft because it's incorporated with the Microsoft license. Based on my extensive experience with HCL Notes, I think HCL can make its product better by being more visible on the market because most companies don't support or use HCL anymore, and most integrators work with Exchange or Outlook rather than HCL Notes. Inside HCL Notes functionality, they have to be more visible in the market, which is very important.

A seamless setup ensures smooth communication with comprehensive support
We remain a partner with Sophos and use XG S Firewalls without AWS implementation. We only use Sophos endpoint and Sophos Central. We host some clients on-premise while others we host remotely. The VPN connection is easy and proprietary, so it's not open to any other VPN clients. Communication with other mail servers is seamless. It can communicate with Gmail and Outlook without issues, provided the DNS settings are correct. We monitor our servers and security logs, implementing GeoIP blocking. We frequently block China and India IPs due to brute force attacks on our servers. We have extensive experience with KerioConnect. Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly. On a scale of 1-10, this solution rates an 8.

Quotes from Members

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

Pros

"Security is the most valuable feature, better than you get in 365."
"People criticize Notes because its appearance is outdated, and I agree, but behind that lackluster look is an extremely substantial platform for knowledge management, information sharing, monitoring, workflow, etc."
"I prefer to work with HCL and not with Exchange because it's easy to manage, easy to set up, and easy to migrate."
"HCL Notes has a non-structured database and fantastic native security, which is extremely strong, providing built-in security without needing external products."
"The initial setup was easy for me."
"The offline access feature in HCL Notes helps me significantly due to its strong replication mechanism, allowing me to work wherever I am, and when I connect, it facilitates two-way replication of information."
"It is one of the best products in the world for workflow applications."
"The most valuable feature is the UI."
"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."
"We have contacted technical support a handful of times and received some assistance."
"Kerio Connect is secure, flexible, and easy to control from the user interface. It has many security features able to be controlled from one place, such as anti-spam. I have found it very convenient. Additionally, you can analyze log files and share folders which is helpful."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"The solution is easy to maintain, unlike Exchange. It's easy to create multiple domains and back up and restore if needed. It also has good security features like anti-spam and antivirus."
"This solution is our SMB alternative to Exchange, installed for more than forty SMB customers in a Linux environment with all of the collaboration features."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"It's relatively simple to use."
 

Cons

"The solution could improve by adding some more features."
"I would like to see integration with other solutions."
"The interface could be more user-friendly. Some additional trainings could be added as well."
"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."
"My overall experience with HCL Notes is not good."
"The problem with Lotus Domino is that there are no new versions of the product."
"Based on my extensive experience with HCL Notes, I think HCL can make its product better by being more visible on the market because most companies don't support or use HCL anymore, and most integrators work with Exchange or Outlook rather than HCL Notes."
"Notes needs a major upgrade for the UI."
"I would like to see better support from their support team."
"I don't particularly like this solution. I would not recommend this solution to others."
"KerioConnect is stable as long as you use a strong password."
"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."
"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow."
"The solution could improve the redundancy because we only have one copy of the Kerio Connect server on our hardware. The next step for us is to move to the cloud and if Kerio does not have a cloud version available they should release one"
"Having a native Outlook map integration would make Kerio Connect better."
"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."
 

Pricing and Cost Advice

"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."
"The solution is expensive. There are many components or features which make the price very high."
"It was reasonably priced, but the product itself was not worth the cost."
"The price is reasonable."
"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."
"The price of Kerio Connect is better when comparing it to others solutions."
"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
"The pricing is about $3 per mailbox per month."
"The solution's pricing depends on how long you plan to keep it because you pay on a per-year basis. You might have a one-time setup cost for something like Microsoft Exchange or a Linux mail server. I'd say this solution is expensive on a per-year basis, almost 2000-3000 dollars annually. It doesn't seem to pay off yet, so we're considering switching to another product."
