|---|---|---|
| Angular developer at Flourish software | 4.0 | I find Security Onion excellent for network security monitoring, threat detection, and log management. It's stable, scalable, and free, offering great ROI, though its initial setup is challenging. I rate it 8/10. |
| Scientist at a educational organization with 10,001+ employees | 5.0 | I use Security Onion for learning and demonstrating security concepts. It's a mature, easy-to-install open-source solution. While setup is easy, learning it takes time, and deploying it in industrial environments presents data acquisition challenges. |
| Cyber Security Officer at AFC Holdings | 3.0 | We use Security Onion for vulnerability assessment. It's free and generally stable, but I find the UI, reporting, and setup need improvement. Scalability and API integration can be difficult, requiring skilled users. Overall, I rate it 6/10. |
| Postgraduate at a educational organization with 1,001-5,000 employees | 3.5 | I've used Security Onion for a year, finding its port infection detection and Squert useful, despite a slightly difficult initial setup. It's a free, open-source solution with good support, which I recommend, rating it seven out of ten. |
Security Onion is primarily used for network security monitoring, threat detection, log management, and centralized visibility across our infrastructure, serving as the primary means for our organization.
Security Onion is used in our organization by continuously leveraging the Linux platform, Linux system, and network-based architecture to monitor threat detections and log management systems, which has proven very helpful for our organization in terms of network security monitoring.
The most valuable features of Security Onion are its threat detection capabilities, centralized log management system, and network security monitoring.
Security Onion has positively impacted our organization by providing features such as log management and threat detection, alongside network security monitoring, which creates a significant impact in our environment, particularly in incident investigation support.
Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use.
I assigned a rating of eight out of ten because the initial setup requires documentation reading and planning, which could be improved to make it easier for first-time users.
I do not think of any other improvements for Security Onion.
I have been using Security Onion for approximately nine months.
Since using Security Onion, we have not faced any issues or downtime, which indicates it is very stable.

I advise organizations that use Linux or have network security knowledge to consider Security Onion, as it satisfies requirements such as threat detection and log management systems.
I would rate this review eight out of ten.
The solution is used to learn how the tools work. It enables us to do consulting and demonstrate solutions. We develop attacks, detect them, and demonstrate how it works. The customers are interested in seeing how and what these tools can do.
We are only working with open-source products. The tool is very easy to install and easy to update. A lot of interfaces are specified. So, it's quite easy to make extensions. It is very important when we do experiments and try to connect and integrate other tools. Security Onion is the most mature solution in the open source world. This is its biggest advantage.
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.
I have been using the solution for about ten years. I am using the latest version.
There is a community. If we are active and ask people questions, we get answers. We also have the option to buy support for difficult problems.
We also use Malcolm. It is a similar platform. But it is not as mature as Security Onion. The system management features are not perfect and need to be improved.
The solution is partially in a real environment and partially in a virtual environment. The focus is on the OT environment. Our main focus is to deliver security in automation systems. It is very easy to set up.
It is an open-source solution. The vendor also sells a hardware solution (appliance) as a paid solution.
My advice depends on the requirements, network, and resources available in an organization. It also depends on whether someone is looking for a turnkey solution, whether they are interested in working alone, and what their skills are. There is no one solution for all installations. Overall, I rate the product a ten out of ten.
Security Onion's user interface could be improved. The solution's general reporting should be made simple and better-looking in terms of graphics so that we can update our senior management.
I have been using Security Onion for four years.
