Provides granular queries of security logs and real-time alerting helps me mitigate risks
The real-time alerting helps me mitigate risks. For example, someone adds a member to the domain admin group. We have an alert set up, so if someone does this unexpectedly, we get notified. Then, we can check and verify if the action is legitimate or a potential threat to the environment.
Hiten Nandasana - PeerSpot reviewer
Angular Developer at Flourish Software
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.
