A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We use Security Onion for internal vulnerability assessment."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
"Wazuh automatically scans the host for CIS benchmarks for the latest updates and vulnerabilities and gives a host score. It provides a percentage of perceived risk due to of non patches or any missing patches on that work."
"The MITRE ATT&CK correlation is most valuable."
"It is excellent in terms of visualization and indexing services, making it a powerful tool for malware detection."
"Integrates with various open-source and paid products, allowing for flexibility in customization based on use cases."
"I would recommend Wazuh to others."
"We found the MITRE framework mapping and the agent enrollment service to be the most valuable features of Wazuh."
"I find the PCI DSS feature the most valuable, along with the feature that monitors the compliance of Windows and the CIS benchmarks on other devices like Unix or Linux systems."
"Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs."
 

Cons

"The product is not easy to learn."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
"It would be better if they had a vulnerability assessment plug-in like the one AlienVault has."
"While it is scalable, it can suffer from reduced latencies."
"There's not much I like about Wazuh. Other products I've used were a lot more functional and user friendly. They came with reports and use cases out of the box. We need to configure Wazuh's alerts and monitoring capabilities manually. It'd be nice if we could select from templates and presets for use cases already built and coded."
"The product's configuration part and lack of AI capabilities are some of the major concerns associated with Wazuh."
"The technical support can be improved. Wazuh has some bugs that need to be fixed."
"Wazuh's scalability and out-of-the-box functionality are slightly lagging behind, but Wazuh has improved a lot since the first time we saw it."
"Log data analysis could be improved. My IT team has been looking for an alternative because they want better log data for malware detection."
"The computing resources are consuming and do not make sense."
