Great for PCI compliance but issues with stability and large amounts of data
I mainly use this solution to meet PCI compliance The automation of compliance reports and the correlation of the log have been major improvements.  The most valuable feature is the predefined reports for PCI compliance. The correlation suite needs to be improved. I also think they need to…

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:

Cons

"There are some issues with the stability - the correlation engine has failed multiple times, and the reports sometimes take too long, so we have to involve the tech team to get them."
"For the NNT Log Tracker and Change Tracker, they have to make their knowledge base available online because there is very little information available on the internet."
"I would like to see the integration of AI technology, so rather than manually monitoring the logs, the tool will understand it and take care of it."
"It is able to identify the vulnerability, however, they need an option to auto-mitigate."
"Only one minor deployment issue came up and it was resolved quickly. No other areas of improvement come to mind yet."
"The correlation suite needs to be improved."
"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."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
