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

"I have deployed it widely because I find that it gives value for money."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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.""
"If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think AlienVault has the best price-performance ratio."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"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 initial setup was straightforward."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"One of the most beneficial features of Wazuh, particularly in the context of security needs, is the machine learning data handling capability."
"It allows you to aggregate all your logs in one place and provides a unified view to monitor your security environment."
"We found the MITRE framework mapping and the agent enrollment service to be the most valuable features of Wazuh."
"The product's initial setup phase was easy."
"Its cost-effectiveness is the most valuable aspect."
"If they support a solution, it is easy to do an integration."
"Wazuh's most beneficial features for our security needs are flexibility, built-in rules, integration capabilities, and documentation."
"I would definitely recommend Wazuh to those who want a SIEM tool as a central logging system and for log management."
 

Cons

"The correlation engine needs to be improved."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The correlation engine needs to be improved."
"ArcSight works better than AlienVault right now."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"Wazuh needs more security features, particularly visualization features and a health monitor."
"The support channel is not optimal, and extensive research is required on our part to implement Wazuh effectively."
"Scalability is a challenge because it is distributed architecture and it uses Elastic DB."
"Log data analysis could be improved. My IT team has been looking for an alternative because they want better log data for malware detection."
"However, in the long term, if you want to build a SOC center on Wazuh, I do not recommend it because it's not stable."
"Wazuh needs more security and features, particularly visualization features and a health monitor."
"The biggest part that's missing is threat intelligence. It isn't inbuilt, and if a sudden incident occurs, we don't get that feedback inside the SIEM tool."
"They need to go towards integrating with more cloud applications and not just OS like Windows and Linux."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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."
"We are using the community version, which can be used for free."
"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."
"The tool's licensing costs are yearly."
"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."
"The solution is open source, so it's free to use."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"There is not a license required for Wazuh."
"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."
"It is a cost-effective solution."
"My client uses the open-source version of Wazuh."
"We use the free version of Wazuh."
"Wazuh is free and open source."
"The solution's pricing is very competitive."
"Wazuh is a good tool, but the open-source version has scalability limitations."
