Room For Improvement

Fortinet FortiAnalyzer needs enhanced UX, report customization, third-party integration, competitive pricing, real-time monitoring, support, and predictive analytics.
Security Onion needs a more intuitive setup, improved UI, enhanced documentation, and reduced complexity for better usability.
When licensing, each device is licensed separately, such as the firewall, which can become expensive.

Product Manager at a comms service provider with 10,001+ employees
Enhanced deep inspection features would make troubleshooting easier.
Head of Technology at Techfruits
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.
A specific guideline for helping beginners understand the detection and investigation features of Security Onion would be beneficial.
BCGEU Faculty, Computer Information Systems Administration at a educational organization with 1,001-5,000 employees
Security Onion could be improved by making the user interface more intuitive for new users and simplifying the initial setup and configuration process.

Setup Cost

Its licensing model is based on the amount of log data processed per day, making it more cost-effective compared to QRadar, which is EPS and device-based.

Valuable Features

Amarnath Jaiswal - PeerSpot reviewer
Senior Manager at a manufacturing company with 501-1,000 employees
Comprehensive log analysis has improved traffic monitoring and streamlined risk mitigation
Fortinet FortiAnalyzer is a very comprehensive analyzer providing detailed analyzing features and customizable reports. I can get customization and custom reports, and there are many functions available. It is very good for any organization.Log management in Fortinet FortiAnalyzer is excellent, as it stores approximately two years of logs. Using Fortinet FortiAnalyzer, I analyze vulnerability risks and threats and sort out problems accordingly. I then create policies and mitigate the risk based on my findings. I have created many customizable reports in Fortinet FortiAnalyzer. I have customized the reports to schedule them and generate reports every day that are sent to my email. I am not using any SIEMs, but Fortinet FortiAnalyzer is the best and looks like a SIEM. I did not integrate Fortinet FortiAnalyzer with any security information and event management solutions. With Fortinet FortiAnalyzer, I have streamlined the process to mitigate risks and save time to get event information on any type of threats, risks, and unwanted traffic. Risk and time are saved, and it is valuable for any organization.

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.
