BP
Independent Contractor at a comms service provider with 5,001-10,000 employees
Enables cost-effective security management for small businesses
Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

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

"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"The dashboard is the solution's most valuable aspect; it brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on," and the solution works well and allows me to have visibility into anomalous events."
"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"Asset discovery is good."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"I have deployed it widely because I find that it gives value for money."
"It's a simple solution you can try for free, and you can get support."
"Wazuh is a powerful tool, and you can do lots of things with it."
"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."
"The product's initial setup phase was easy."
"Wazuh caught my attention as a very cool solution for verifying file integrity."
"The deployment is easy and they provide very good documentation."
"My company implemented Wazuh because it was relatively inexpensive. They could quickly get their hands on it to check a box for some audit and compliance."
"Wazuh offers an enhanced HDR version that outperforms its competitors."
 

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The biggest thing I always complain about is that the user intake is a very old version."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"I don't like to work on OSSIM because it is unpredictable."
"Lacking in depth of reporting."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"AlienVault OSSIM gives unwanted notifications."
"Integration with Vyara could be better."
"Wazuh should come up with more in-built rules and integrations for the cloud."
"Wazuh requires substantial maintenance. The indexer frequently times out, requiring system restarts. When it comes to errors, debugging takes considerable time."
"We would like to see more improvements on the cloud. They need better cloud integration."
"Alerts should be specific rather than repeatedly triggered by integrating multiple factors. This issue needs improvement to create a more efficient alert system."
"The implementation is very complex."
"The product's configuration part and lack of AI capabilities are some of the major concerns associated with Wazuh."
"Log data analysis could be improved. My IT team has been looking for an alternative because they want better log data for malware detection. We are also doing more container implementation also, so we need better container security, log data analysis, auditing and compliance, malware detection, etc."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."
"We are using the community version, which can be used for free."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"The tool's licensing costs are yearly."
"OSSIM is free."
"AlienVault OSSIM is free."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"There is not a license required for Wazuh."
"The current pricing is open source."
"They have a good pricing strategy for market expansion."
"The product price is neither too high nor too low."
"Wazuh is an open-source tool."
"Wazuh is not an expensive solution."
"The solution's cost is above the average."
"It is a free-of-cost solution."
