| 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. |
