Quotes from Members

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

Pros

"The ease of use in the GUI itself is the most valuable feature. The GUI is really the best part of it. We like the traffic rules so we can control who can get to what. It's easy to determine the flow of the traffic itself so we aren't having to guess through command lines and reading out basically command-driven output. It's just a very easy-to-use interface. The interface is the best part of the product."
"This solution has improved my organization because we can access remotely."
"We also like the security. We can control what sites users can go to and we can make sure that where they're going is appropriate and that it's work-related."
"The stability of Kerio Control is good."
"Instead of using a cloud-based product for accessing information, and putting my data at risk in the cloud and in someone else's hands, it has allowed me to use a VPN and access my data directly from a laptop when I am out in the field. That has made my life a lot easier, where I'm able to access any information I need to be able access, basically on demand, with an Internet connection. That alone has been great."
"The most valuable feature is to provide users with the ability to log in to the portal page, keep track of their data usage and perform bandwidth management."
"The firewall and the content filtering options are valuable."
"At the end of the day, our customers are being managed, looked after, and they're secure, so they're happy."
"The app inspection is very helpful for network security."
"The stability of Palo Alto Networks CN-Series is excellent."
 

Cons

"Improvements are needed to the Next Generation Firewall Protection, specifically with user-level protection."
"They should improve the remote connectivity feature for users."
"I would like for there to be a difference between international and national links."
"Kerio Control could improve content filtering."
"I would like for them to add more security features."
"The Kerio hardware devices look cheap and could be improved. Some of our clients are switching to Sophos because their hardware has a more sleek design."
"The one thing that did put me off of the solution was that, after they were taken over by GFI, the licensing and a few other items have gotten very complicated."
"The improvement that we are looking for is for when we decide to move some part of our application to the cloud."
"I'd like to see more IOPs features."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
 

Pricing and Cost Advice

"It gives us a lot. It does prove to be a very robust product for the cost."
"The yearly maintenance fee is a bit high for the Kerio Control Boxes. The end of life for the devices is kind of short. It seems like they're making you upgrade within a short period of time. They should at least allow five years, but it seems like they are changing their end of life to be shorter to generate revenue."
"The price of Kerio Control could be better, it is a bit overpriced compared to other solutions."
"I am living in Iran and we cannot buy the product from Kerio because of sanctions."
"Our clients see ROI with Kerio Control, as they are saving bandwidth costs."
"The price is fine."
"It gets expensive pretty quickly if you need to purchase license packs."
"Licensing is easier with Kerio Control. With FortiGate, we realized the licensing is really hectic, because if you skip one year, you have to back pay that year. If you skip two years, you have to back pay two years. With Kerio Control, if a license expires, one year later you can just reactivate and go on."
