Centralized monitoring has strengthened threat detection and supports faster incident investigations
Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization. Security Onion integrates well with our existing tools, primarily using Linux systems in our organization, allowing us to monitor logs and manage threat detection and operations in the public cloud effectively. Security Onion is very helpful in meeting compliance requirements and supports regular standards for our environment. 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.

Quotes from Members

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

Pros

"The automation feature is good because if your CMDB is OK and it is already in sync, then the automation part is good to go."
"The tool has given a great visibility of what is going on our network and has helped to troubleshoot network-related issues quickly and accurately."
"Data Insight reporting tool is the most valuable feature. They came up with it a couple of years ago. The most pleasing factor is the dark theme. You don't have a white background. It has templates that you can create for all kinds of reports that you can hit on the fly. It's much better printing of the reports. If you want to send PDFs to people, the reports are actually decent. Whereas for years, the old architecture of the PDFs was rubbish and even our customers said, "We have to manipulate your PDFs because they all have bad margin breaks. SevOne fixed that a couple of years ago with the new Data Insight. It's fantastic."
"Flexible architecture: You can extend the system and its capacity by attaching another cluster pair."
"Scalability. I have never had to worry about how to handle really big environments."
"In summary, for our requirement, SevOne does pretty much what we ask and does it very well."
"The reporting capabilities provided important metrics and data that helped in the oversight of our system, network, and overall IT infrastructure, both in terms of applications and hardware."
"It's a great solution for highlighting and discovering useful information regarding our network's elements."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"One area that requires a little bit of improvement is the topology of visualization and being able to map out connections, end-to-end. It's able to do that, but it's not as impressive as we would like it to be. We would like to understand the different interface types and the connection points better, through the visualization. Heatmaps also need further development."
"High-frequency polling is data-intensive because you're pulling more. If SevOne could figure out a way to manage the impact of high-frequency polling on the system, that would be very popular."
"Some of the services and functionality are adapted for SevOne via open-source, and the cost is very high. For the price that they are asking, it cannot be justified."
"I think that the downstream suppression could be improved."
"The one area with room for improvement is probably administration. They added data insights to make a better user experience, but I'd like to see some improvements in the way the system is administered."
"There are some tweaks and enhancements that I've already requested. One is to be able to make changes per device rather than as a global setting. That has to do with naming. It's minor."
"With the administrative management of the appliance, if some object appears from SevOne because something changed in the network or whatever, then as an administrator you will not be aware."
"Features like SMS support and a faster way to create objects in calculation editor would be good."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
"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."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"The pricing has been fair."
"The pricing has not evolved with the market, which is one of the reasons we are moving to a new product."
"The tool is not expensive. We were able to negotiate with SevOne on pricing."
"There are cheaper solutions available."
"Have a bank of licenses, because it is about the number of objects (RAM, ports, CPU, etc.)."
"Although I don't have exact details in terms of cost, my experience has been that SevOne is willing to make a deal with the customer."
"Many tools price things based on the number of KPIs that you're collecting around a device. In many cases, there could be hundreds of metrics that you need to collect. SevOne provides device-level pricing. That gives us the flexibility to turn on, and expand on, the metrics that we're collecting around those devices, without taking a financial hit."
"Choose a SevOne partner who can provide SevOne as a service and can deliver professional services and maintenance."
"Security Onion is a free solution."
"It is an open-source solution."
"Security Onion is an open-source solution."
