Room For Improvement

LogRhythm SIEM needs improved integration, customization, performance, usability, better support, and enhanced documentation for optimal user experience.

Security Onion needs a more intuitive setup, improved UI, enhanced documentation, and reduced complexity for better usability.

I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

SaiKrishna2

Cyber Security Engineer at Diyar United Company

There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments.

SumitKumar20

Security Engineer at Granicus Inc.

If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity.

Rajin Sandira

Engineer Information Security at N-Able (Pvt) Ltd

Rajin Sandira

Engineer Information Security at N-Able (Pvt) Ltd

Advanced threat detection has improved investigations but complexity and resource use need refinement

LogRhythm SIEM could learn from Wazuh, as Wazuh has a built-in mechanism that allows you to write custom scripting and scripts through languages that Wazuh can then trigger, which is somewhat better and more matured in Wazuh compared to LogRhythm SIEM. Additionally, the parsers that I write for LogRhythm SIEM tend to get quite complex for log parsing, while with Wazuh, I can achieve a similar parser with much less complexity. Those are some of the pain points that some of our customers have been expressing. If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity. Therefore, they have been moved to Wazuh, which I am deploying for them. Even though LogRhythm SIEM has extremely good capabilities, their resource utilization is too heavy for certain customers, so if they could make a separate, lightweight version, that would be quite beneficial.

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.
