Valuable Features

KerioControl's most valuable features include ease of use and configuration, firewall and intrusion detection, VPN capabilities, comprehensive security, traffic shaping, robust reporting, and two-factor authentication. Users appreciate bandwidth management, traffic rules, VLAN options, content filtering, and IP address flexibility. The system's real-time monitoring, stability, integration with Active Directory, and manageability make it ideal for various infrastructures. Additionally, KerioControl offers automated security updates and a user-friendly interface.

"The most valuable features include geo-tagging, which blocks all other IPs except for the specified accounts, and web filtering."
"The solution has an app manager and a portal where you can maintain all your Keri products. It is a firewall that includes antivirus and anti-malware, which adds security. The VPNs, both site-to-site and client VPNs, are pretty easy to set up."
"The tool shows what has been blocked externally. It's very good because once installed and correctly set up, it allows you to work from home as if you are in the office, without any errors or issues. It's very simple to use, click to connect or disconnect."

Room for Improvement

KerioControl users highlight several areas for improvement, including VPN configuration and the need for more GUI options. Support services require enhancements, with some experiencing delays or insufficient assistance. Users desire increased security features, flexible VLAN configurations, enhanced content filtering, and detailed logging. High availability, improved diagnostic tools, and updates to address system bugs are necessary. The complexity of certain features poses challenges for novice users, suggesting a need for a simpler interface. Performance issues and hardware design also warrant attention.

"KerioControl has met some of the network infrastructure needs yet could improve in terms of scalability, which I rate four out of ten."
"The logs could be improved for better clarity."
"The solution's hardware is not that great and could use more improvement. However, the VM software and the virtualized KerioControl itself are pretty good. The software is good; it's just the hardware that needs improvement."

ROI

KerioControl users report significant cost savings and efficiency improvements. Many experience reduced internet bandwidth expenses and decreased time managing security, benefiting from seamless VPN capabilities and remote access. Investments in KerioControl allow fewer errors and secure connections, leading to improved productivity and cost-effective security. Customers note that the ease of use and minimal downtime contribute positively to overall network management. Some express concerns over licensing costs but appreciate the reliable performance.

Pricing

KerioControl's pricing is generally considered affordable and reasonable, especially for small to medium-sized businesses. Many users appreciate the cost-effectiveness, particularly when purchasing through GFI Unlimited, offering comprehensive options. The licensing process, however, can be complex, with fees determined by the number of users and IP addresses, and some users find setup and subscription clear yet occasionally costly. Annual licensing or renewal fees apply, and optional feature upgrades may involve additional costs. Discounts are available for larger user bases.

"There's a one-time fee. For KerioConnect, it's just a server. With KerioControl, you have an option. You can virtualize it on a VMware system or have the hardware. I think mid-range or desktop KerioControl hardware could cost around 2000 dollars for a 25 user client. You need annual renewal for additional features like antivirus."
"KerioControl's pricing is reasonable. The license for KerioControl is annual. It's difficult to specify an exact cost since it varies depending on the number of users and additional software combined with it. For example, a basic box might cover 25 users, but licenses can be purchased starting from 10 users."
"We have to pay approximately EUR 175 for the product."

Popular Use Cases

KerioControl is primarily utilized for comprehensive network security, including firewalls, intrusion prevention, and web filtering. Users leverage its VPN capabilities for secure remote access and site-to-site connectivity. It effectively manages bandwidth and provides user statistics, making it ideal for small to medium businesses. Clients maximize internet connections on superyachts and use it in data centers for EPM platforms. It supports firewall functionality, content filtering, and reliable antivirus protection while offering easy management.

Service and Support

Customers find KerioControl support mixed. Some experience slow response times, while others say it's responsive and helpful. Many note that support quality declined after GFI's takeover, leading to more difficult access and less personalized assistance. Users often rely on online resources or resolve issues independently due to inconveniences in communication. Some regions report inadequate local support, and premium clients express dissatisfaction with delayed responses. Despite these issues, a segment still finds the support satisfactory.

Deployment

Many describe KerioControl's initial setup as straightforward and user-friendly, often taking one to two hours. Some mention a short setup time, while others note the need for adjustments or complexities based on individual requirements. Deployment can vary from 10 minutes to several hours, with factors like the environment affecting duration. Users emphasize the intuitive interface and minimal time needed for maintenance, stating that even complex setups become manageable with experience.

Scalability

KerioControl is effective for small to medium-sized enterprises, handling various setups with ease. Users report it scales adequately within certain limits, supporting hundreds of connections. On virtual appliances, expansion is simpler, but hardware appliances may need upgrades for increased demands. Organizations say KerioControl maintains network functionality and integrates seamlessly, though not suitable for scaling to large enterprise networks without challenges. Its flexibility and performance are valued, though some users mention limitations in advanced scalability features.

Stability

KerioControl generally exhibits strong stability, particularly in Load-Balancing mode, with frequent updates enhancing its performance. Several users noted minor issues, often related to hardware rather than the software itself. Occasional reboots or adjustments might be necessary, but the software's reliability is widely appreciated. Some users experienced glitches or required restarts, but KerioControl's resilience and overall functionality received praise. Most found it robust, with some acknowledging hardware-related problems rather than software faults.

Reviews from Real Users

Here is some feedback from some of our users who are currently using the solution:

PeerSpot user Brian C., Senior Technology Specialist, VP at Unified Technology Solutions, writes "It is very comprehensive and simple. It has all the active protections. It's updated. We love that you can set how often it is updated so you can work on what is right for you. A large company with a lot of bandwidth can update the virus definitions and security definitions hourly, if they want. A smaller site that's remote, where maybe updating the definitions will eat into the bandwidth, we can schedule those more to go later at night. It's very flexible and works for us in all types of situations. This is great because then we don't have to learn seven different products to be able to work with seven different scenarios."

Andy D., IT Manager at Flare Technologies, praises how easy it is to use and says, "One thing we use quite a lot, as well, is the DHCP Server, because we do a lot of work where all our devices need to have static IP addresses. Rather than going around and configuring every box, we do it all through DHCP reservations. It's easier. We've got a record of it. We can manipulate it if we need to change something or change some hardware. It's all easy. Even guys who are not used to using it can pick it up quite quickly."
