Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Improved threat detection and incident response has revealed training and usability gaps
What I would like to add is that if the interface or if there is less to work on technical knowledge. For example, people with no technical knowledge cannot use this, so they need to have at least a deep or substantial level of technical knowledge to be able to use these tools. If there is a way there can be an optimization to accommodate those with no technical knowledge in the process using tools compared to tools such as Sentinel and Splunk, which also doesn't require much technical knowledge to be able to use. That would also help. I think Security Onion could be improved by making the user interface more intuitive for new users and simplifying the initial setup and configuration process. Security Onion needs to be simplified so that those with less technical knowledge can be able to come in and use it. Guidance on prioritizing alerts will also be helpful, especially in an environment where security analysts deal with a high volume of security events. I also would like to mention that it needs to be more straightforward integration with other security tools. There needs to be a handshake between Security Onion and other same tools to help in endpoint detection and protection against threats. Another improvement that could also enhance is the reporting and visualization of the key metrics such as detection time, the incident, the overall interface of the analysis, and the false rate, which will also give Security Onion a better view for security analysts to be able to use and understand it. I would like to see the interface to be more simplified. I also would like to see the visualization to be more improved. I also would like to see the support features to be something that junior analysts or those coming in to start up their careers can be able to use without needing deep technical knowledge.

"What I would like to add is that if the interface or if there is less to work on technical knowledge."
"The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
