IT Admnistrator Information Technology and Services Used the software for: 2+ years ### "Easy to use Firewall / UTM" August 3, 2019 4.0 Overall satisfied, does its job well. Pros Really nice and easy to understand interface. Pretty stable, reasonable price. Support is good aswell. Good option for small to medium business. Cons Lacks features and options, like automatic IP blocking or allowing to create custom IP / port rules with the country lists it already has (now only allow to select countries to deny access to all IP and ports). Review Source Majid S. Freelancer Computer Software Used the software for: 2+ years ### "Good choice for Average sized companies." November 6, 2019 4.0 I have used it for some of my clients for several years. It is easy to use solution and supports the vast majority of your needs from a firewall and Internet sharing software. Pros I have learned Kerio Control myself easily. Traffic rules work very well. Reverse Proxy is a useful facility. Internet Usage Reports are approximately perfect. I love the feature that I can limit the Internet speed of users after using their quota. It needs the minimum hardware resources and by using a virtual appliance, Installation is easy. Integration with Microsoft Active Directory is very nice and perfect. Meanwhile, defining users out of Active Directory is possible. limiting users to different time intervals is also a very good feature. for example, I have limited a user to use the Internet at nights just to update my servers when other users are not using the Internet. Cons Kerio VPN Client is not completely bug-free! Sometimes, it can not be connected to server without any specific reason. Load Balancing does not work very well. Kerio Control reduces the speed of the internet when there are too many traffic rules. Review Source LW Logan W. IT Administrator Real Estate Used the software for: 1-2 years ### "Some good some bad" January 28, 2019 3.0 The antivirus, peer to peer, and alerts work very well. Customer service is good when they know how to solve a problem. If they don't expect to be passed back and forth between agents until your case escalated. They will do a remote session to see if a senior agent/manager can figure it out. If they can't then you are pretty much out of luck. In my case anyway. Also if you you ask them to show you how something works that can be hit or miss. Sometimes their agents are happy to help you. Sometimes they act like you are dumb for not figuring it out. Pros It is fairly easy to use once you get the interface down. Also when you make changes it happens pretty quick and stays how you changed it. You really wont get any surprises that come out of no where really. Cons If you do have a problem it can be hard/impossible to narrow it down. I have had several issues that I spoke with support with (through email and phone) that they werent able to figure out. Like hours on the phone, dozens of emails. And they just wouldn't know. I dont expect them to know everything but they were just so baffled by some stuff. So I just learned to live with the problem. Like the IPS in Kerio really slows down our internet speed. Spoke with many people about it. Took months and finally after they couldnt they said we dont support your hardware anymore. Why didnt they tell me that just right out of the gate. It was very frustrating Review Source VR Verified Reviewer Freelancer Computer Software Used the software for: 2+ years ### "An adequate solution for SME's " July 3, 2018 4.0 It has been our firewall in our company for 10 years Pros 1- Easy to learn and setup and it's really user-friendly 2-Very good integration with Microsoft Active Directory 3-Good Internet usage report. 4-Mac Filter is really good 5-Defining Traffic Rules is perfect and easy. 6-Supporting reverse proxy server is a very good facility. Cons 1-load balancing doesn't work properly most of the times. even when you set connectivity weights. 2-It's a little bit slower than some other solutions such as Mikrotik 3-without it's own specific VPN client (and other VPN connections), users sometimes are not distinguishable by this software and sometimes the traffic rules can be bypassed. for example, we have set that only authenticated users can use the Internet, but a VPN service such as PrivateTunnel can connect to the internet without login to Kerio control, bypass the rules and connect to Internet! Review Source VR Verified Reviewer System Adminitrator Financial Services Used the software for: 2+ years ### "A Very Cost-efficient Alternative to Microsoft Exchange" January 30, 2019 4.0 Pros Kerio Mail and Connect Clients are simple to configure, integrates easily with Microsoft Active Directory in a domain environment and we can have our entire mail store on-premise for easy management. Mails are delivered almost instantly for LAN communication and very quickly over the internet. Overall, it's pretty robust with a low-cost-compared-to-Microsoft yearly license that gets the job done. Perfect for small to medium organizations. Cons The Kerio Connect Client often freezes for a few seconds while navigating, but not so much that it breaks concentration or affects productivity.

Pros It’s a simple, yet reliable VPN. I use it daily and cannot enjoy more its connection that is as speedy as it is reliable. Another pro worth mentioning is the software unintrusiveness. KerioControl always runs in the background without bothering me with pop-ups and other signs of its activity. Cons Having used KerioControl for over half a year, I cannot think of any complaints other than an occasional connection drop. However, it happens too rarely to impede my productivity.

Also what I most likely: Kerio Control is totally intuitive.

July 20, 2023 5.0 Kerio ha velocizzato i processi informatici della mia azienda, dando sicurezza eccellente ed una risposta veloce al cliente finale quando si trattava di creare/implementare filtri o regole aziendali. Pros Prodotto molto affidabile e molto semplice da utilizzare lato amministratore. A differenza di tanti altri firwall è anche molto veloce nella creazione delle regole; degli utenti e di tutto ciò che può essere personalizzato per la sicurezza aziendale. Molto semplice ed intiutiva anche per l'utente finale è la parte VPN. Cons Penso che dovrebbero renedere l'hardware un po' più performante. I Box si surriscaldando molto (in paritolcare l'NG110) e capita qualche volta che si rompano addirittura. Alternatives considered [Sophos Central Device Encryption](https://www.capterra.com/p/241751/Sophos-Central-Device-Encryption/)[Nexi](https://www.capterra.com/p/185302/Nexi/) Reason for choosing KerioControl Facilità di gestione e per l'affidabilità del prodotto.

Business Development Food & Beverages Used the software for: 1-2 years ### "Non soddisfatto" June 6, 2024 3.0 Pros Il sistema di controllo all'accesso è sicuramente efficace. I costi non sono esorbitanti. Cons Non lo riprenderei perchè rende la gestione della rete, delle autorizzazioni, della VPN molto complicata e farraginosa. Preferisco altre soluzioni e le adotterò appena possibile. Review Source HT Hugues T. System Administrator Information Technology and Services Used the software for: 6-12 months ### "A great network solution." July 4, 2023 4.0 Pros The product is easy to use. In less than two hours you'll be master it. Love the design of some of the routers, and that it's fanless. Cons Some updates don't go very well. When updating, keep an eye on it and downgrade it if needed. Maybe wait 1-3 week before upgrade. In the other hand, the documentation is not very clear but it's ok.

VPN was easy to use Cons It is an old product, i changed it one year ago because the product was not updated, is missing on very high features important for security Reason for choosing KerioControl we chose kerio because our provider was using kerio, just for this reason Review Source TZ Tomáš Z.

It offers good active protection and good setup for bandwidth. Good update time. Cons GUI is quite old. Maybe some improvement in looking and also offering more dashboards . Review Source FD Felice D. Management Consultant Food & Beverages Used the software for: Less than 6 months ### "Sistema Complesso da utilizzare" May 5, 2024 3.0 Pros Mi piace sicuramente il buon controllo delle autorizzazioni e l'efficacia in termini di privacy Cons Trovo Kerio un sistema davvero complicato e arcaico e che rallenta di molto le operazioni. Anche solo per collegarsi in Vpn occorre sempre un Token che si rigenera ogni attimo e questo rende le operazioni molto più difficili. Da migliorare anche l'assistenza clienti.

December 16, 2016 5.0 I've been using Kerio since was named "WinRoute firewall" running on windows. Now it is called Control and is just for Linux (an entire distro bundle). I used for small customers and then 14 years ago start working for the Argentinian's Government, I took my fan for Kerio there and Implement that solution for 7 buildings and more than 600+ network devices. 14 years later still using it. Any new need that involves some networking we could easily implement with no any new software. People traveling can easy access to internal applications via VPN. On the primary building, we have a kerio server with 8 nics, guest wifis, private wifi, 3 internet connection, TLS with other building, LAN and DMZ, all with a quad core with 4 GB rams, working flawlessly. For far kerio control was the best app for syusadmin that I never used. Made make day to day work enjoyable. Review Source MA Mansour A.

Please support in Arabic.
