Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.

Has faced limitations in AI capabilities and pricing flexibility
Pricing-wise, Wazuh stands out, along with deployment flexibility and its documentation which is extremely good in comparison to Forti. The community support is also incredible. They have helped quite a bit because previously, we had a separate tool and management dashboard to do our compliance. With Wazuh, we receive that information without having to do anything extra. We just set up the SIEM and all of that information was automatically populated. The dashboards are very easy to understand and very quick with no lag or delay. I have experienced delays on Forti's dashboards, but not with Wazuh. Wazuh is quite good. In comparison to Forti, they are quite similar. They are very good at detection.
