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.

Centralized archiving has transformed how we manage compliance, audits, and investigations
Overall Proofpoint Intelligent Compliance Platform is a strong platform for compliance and information governance, but there are a few areas where it could improve in the future. One improvement area is the user experience and interface consistency across different modules. Some workflows can feel complex, especially for a new user or the team managing multiple compliance functions simultaneously. Community feedback has also highlighted that certain administrative interfaces and navigation flows could be more modern and streamlined. I also think there is room for improvement in support responsiveness and operational simplicity for complex deployments. Some users in the community have mentioned challenges around the ticket response time and troubleshooting efficiency for advanced configurations that needs to be improved. From a product perspective, a continued investment in AI-driven detection, the reduction of false positives, and easier policy tuning would make the platform even more effective at scale. Proofpoint already provides strong automation and machine learning capabilities, but a highly regulated environment still requires significant tuning and oversight to optimize the workflow. One additional improvement for Proofpoint Intelligent Compliance Platform would be making policy configurations and workflow management more intuitive, especially for organizations with complex compliance structures and multiple regulatory requirements. I also think more customizable dashboards and reporting capabilities would help teams gain faster operational insight and improve visibility into the compliance trends, investigations, and reliable workload.

Quotes from Members

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

Pros

"As long as the operating is stable, the Kerio connect will be very stable as well, so we don't have any problem with it."
"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."
"It's relatively simple to use."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."
"The user interface is good."
"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."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"Our experience with the platform has been positive as it has maintained consistent control over spam and malware threats."
"Overall, Proofpoint Intelligent Compliance Platform is a very strong and reliable platform for compliance, archiving, supervision, and information governance."
 

Cons

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"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."
"We cannot compete with them because they're fully integrated with their applications."
"I would like to see better support from their support team."
"This is just a cost, it's not something that's driving our business forward; it's just foundational."
"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"
"KerioConnect is stable as long as you use a strong password."
"Some workflows can feel complex, especially for a new user or the team managing multiple compliance functions simultaneously."
"The Proofpoint Intelligent Compliance Platform does not provide features that help reduce manual efforts, so additional human resources are still required to manage security."
 

Pricing and Cost Advice

"The price of Kerio Connect is better when comparing it to others solutions."
"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."
"The pricing is about $3 per mailbox per month."
"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
