Very good threat protection, spam filtering, and cloud backups

Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.

Lightweight, simple, and robust; easy to maintain and doesn't require a lot of system resources to run

Kerio Connect does as advertised, so there are no real issues with the product itself. It's developed regularly, so there are constant updates. Possibly, the support and development have lessened since they've sold the company, but as far as the product itself is concerned, there isn't anything that I would suggest needs improvement. If I'm being picky, Kerio Connect uses a proprietary, mappy atom for Outlook, and it would be nice if they used a native mappy connection instead, but that's the only additional feature that I would like to see in its next release. If they have native Outlook map integration, that would be great, but other than that, it's got all the functions that I think a mail server should have.

Quotes from Members

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

Pros

"The solution is straightforward to set up."

"The most valuable aspect includes attempts to spoof or compromise domains from external sources."

"I'm quite satisfied with the graphical user interface for Barracuda products."

"The archiving and search features are very good."

"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."

"The most valuable features of Barracuda Email Protection are flexibility and customization."

"I would rate the solution nine out of ten."

"We now have a secondary backup of Office 365 that's much easier to retrieve compared to Microsoft. If someone deletes something in Office 365, we can get it back within Office 365, but it's difficult. Barracuda is much easier. There is a lot less management needed using Barracuda. The management becomes much easier for Office 365 and it's no longer on-prem, so there are fewer hours managing on-prem devices, servers, and things of that nature. We don't have network appliances anymore for the backup of our information."

More Barracuda Email Protection pros

"It's relatively simple to use."

"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."

"KerioConnect has integration with 365. We can use Outlook, which has its client and can be used with Apple devices. It integrates with the App Store and Microsoft Office. It has a smart router. The spam filtering and antivirus are 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."

"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."

"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."

"The user interface is good."

More KerioConnect pros

Cons

"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."

"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."

"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."

"Barracuda Essentials can improve by continually adding more features."

"I would like to see better integration with other products."

"The product must enable bulk user management."

"They could simplify the licensing and the pricing."

"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."

More Barracuda Email Protection cons

"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."

"The search and archiving documentation capabilities need to be stronger."

"We are considering switching to Microsoft Exchange. One reason is that it doesn't improve our workflow and doesn't integrate well with Microsoft 365 applications."

"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."

"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow. They could make it faster to get onto the web interface without so much load time. It's just slow with Outlook, however, for some reason."

"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."

More KerioConnect cons

Pricing and Cost Advice

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."

"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."

"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."

"Barracuda licensing model is good."

"The solution's pricing is moderate, where it is neither cheap nor expensive."

"Price-wise, this product is middle-of-the-road."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."

"The price of Barracuda Essentials is better than some of the competing products."

More Barracuda Email Protection pricing and cost advice

"The pricing is about $3 per mailbox per month."

"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 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."

Overview

The popularity of Microsoft 365 means criminals test and design their attacks to bypass its native security features. And that means you need additional layers of defense. With Advanced Threat Protection enabled, Barracuda uses multiple layers of detection, including signature, static, and behavioral analysis, along with CPU-emulation sandboxing to accurately detect and block zero-hour targeted attacks and ransomware.

Traditional email gateways use static rules and policies—reputation analysis, block lists, and malicious payloads—to determine if an email is malicious.

Barracuda protects your Microsoft 365 inbox against evasive threats with a powerful AI engine that learns the unique communication patterns within your organization through access to internal and historical emails. Once it understands what legitimate emails looks like for each user, it can detect anomalies that signal malicious intent. This context-based detection is more effective at blocking targeted attacks, which are designed to bypass traditional rule-based email security.

Barracuda Networks

Kerio Connect, a messaging and collaboration solution, meets the needs of small and mid-sized businesses while offering a robust feature lineup. Business users enjoy support for their favorite email client and easy web-based access. Kerio Connect is highly stable—so you can focus on business rather than unexpected downtime and recovery.
