They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
I have never needed to contact customer support as the product is easy to use.
I mainly rely on community support since the solution is open source.
The technical support by Sophos is amazing, especially when I pay for the enhanced support.
 

Scalability Issues

Sentiment score
6.9
Fortinet FortiGate effectively supports scalable deployments, offering adaptability despite potential hardware limits and integration and licensing concerns.
Sentiment score
6.7
KerioControl suits small to medium businesses but faces scalability issues in larger enterprises, requiring hardware upgrades for increased capacity.
Sentiment score
6.5
OPNsense is scalable for diverse organizations, efficiently supporting different user volumes, with some challenges in high-volume voice traffic.
Sentiment score
8.5
Sophos UTM scales well with proper sizing, enabling easy expansion in various environments from small setups to large networks.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
KerioControl has met some of the network infrastructure needs yet could improve in terms of scalability.
Aside from these aspects, it demonstrated good scalability.
It supports routing, VPN setups, and traffic monitoring with additional packages like Snort and Suricata.
OPNsense is an extremely scalable solution.
 

Stability Issues

Sentiment score
7.4
FortiGate is praised for stability and performance, with minor challenges managed by updates, proper sizing, and support.
Sentiment score
7.2
KerioControl is stable and reliable, with minor hardware or update challenges, and performs well according to user assessments.
Sentiment score
8.5
OPNsense is stable with high ratings, despite issues with VPN failover, occasional bugs, and hardware compatibility concerns.
Sentiment score
8.3
Sophos UTM is stable and reliable, with minimal issues, though updates can occasionally cause temporary problems.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
OPNsense is the same, but it does have a way of installing the Realtek drivers, which gives you a lot more stability overall on the system.
The only challenge faced was its inadequacy to manage large voice traffic effectively, even with dedicated hardware.
At the latest code level, I haven't experienced any crashes.
 

Room For Improvement

Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
KerioControl requires improvements in VPN, user interface, support, security, performance, and customization features for large networks.
OPNsense faces challenges with integration, user interface, documentation, scalability, performance, and security features, needing enhancements in various areas.
Sophos UTM users seek improved scalability, performance, VPN capabilities, interface usability, cost transparency, support, and simplified management features.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
For high availability, it's crucial to have a method in place where a designated component oversees the entire process.
Improved guidance on package usage and integration beyond relying on external tutorials or community support would be beneficial.
I would like the APIs to be more mature and more developed and have more options to automate threat hunting.
I would love to see artificial intelligence capabilities integrated into Sophos UTM.
With artificial intelligence, there is room for improvement in all antivirus and security software.
 

Setup Cost

Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
KerioControl offers affordable pricing with complex licensing, appreciated features, but high annual fees can be challenging for small offices.
OPNsense is a cost-effective, flexible solution for enterprises, preferred over costly alternatives like FortiGate and Palo Alto.
Sophos UTM offers competitive pricing with varied licensing options, though some users find it costly compared to alternatives.
FortiGate is priced lower than Palo Alto.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It is about 20% cheaper.
The price for the product is rated as ten out of ten.
It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident.
I would rate the pricing a nine out of ten, especially considering the availability of a free community edition.
It is free.
Pricing has become expensive recently due to the dollar hike and naira value changes in Nigeria.
The value between what I receive and what I pay is the best in the industry.

The most valuable features include geo-tagging, which blocks all other IPs except for the specified accounts, and web filtering.
The most valuable features include the basic firewall functionality and the GeoIP location services.
OPNsense is easy to use and open source.
The DNS-level filtering is impressive for thwarting time scanners.
The zero-day protection and firewall rules are some of the most effective features for threat management.
This integration of the antivirus and the firewall works together to enhance security.

Vasu Gala - PeerSpot reviewer
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.
Constantnos Achilleos - PeerSpot reviewer
Leveraging geo-tagging and web filtering for enhanced network security
The solution is used for site-to-site VPN connections and it is valued for its cost efficiency and easy connectivity. It is especially beneficial for multi-site VPNs and is used in about fifteen different components KerioControl has provided a financial benefit as it allows purchasing one license…
Akram Zaki Hussein - PeerSpot reviewer
Robust network security and management offering a user-friendly interface, open-source flexibility, and cost-effectiveness, with challenges regarding initial setup and the absence of official support
The interface is user-friendly, but there's room for improvement in terms of intuitiveness. The bundle management aspect requires additional attention to make it more intuitive, especially for inspecting high-level traffic. This is crucial, especially for larger companies where the existing features might not be the most optimal choice, given limitations like printer constraints. For high availability, it's crucial to have a method in place where a designated component oversees the entire process. Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine. It would be beneficial if OPNsense supported additional virtualization platforms like Hyper-V from Microsoft and VMware, similar to how Kaspersky has integrated them.
Samaila Yusuf - PeerSpot reviewer
Network protection strengthens through effective threat management features and secure access control
The zero-day protection and firewall rules are some of the most effective features for threat management. I can set the rules and features, and also use IPsec to connect all my on-premises servers and link them to Sophos UTM so that they are protected even when in the cloud. Additionally, I use it to control access into the building through a captive portal integrated across all the PCs we have, ensuring secure access only for authenticated users.
