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.

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

"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."
"The paid version of the solution has reporting and better scalability options."
"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.""
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"Asset discovery is good."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The initial setup was straightforward. I didn't have any problems."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"Wazuh offers an enhanced HDR version that outperforms its competitors."
"Its cost-effectiveness is the most valuable aspect."
"The most valuable feature of Wazuh is its EDR capabilities."
"Wazuh is free and easy to use. It is also adjustable, and we can use it on the cloud and on-premises."
"When we talk about functionality, the most valuable feature or function I have found in Wazuh is Wazuh EDR agent with EDR capabilities."
"Regarding Wazuh, I find the SCA (Security Configuration Assessment) features most valuable. It's crucial for asset management and inventory, allowing us to monitorendpoints and servers' changes easily. This is particularly important for my customers, who aren't heavily focused on incident response but rely on asset management and inventories. Wazuh's compliance management features are very supportive, especially in regions like the Americas and Europe. However, it's less effective in the ANZ (Australia and New Zealand) region since Wazuh doesn't cater to the specific compliance standards there, such as those required in Australia. I appreciate that Wazuh fully complies with PCI DSS and GDPR standards, allowing us to generate necessary reports."
"I like that the solution is on top of the Kubernetes stack."
"The configuration assessment and Pile integrity monitoring features are decent."
 

Cons

"The correlation engine needs to be improved."
"It's so hard to configure and explore something new on it."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"AlienVault OSSIM gives unwanted notifications."
"They can add more compliance templates."
"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. That's a big gap, I see. It would be better if we could get the threat intelligence feeds integrated with the SIEM tools. That would help us push value solutions to the clients in a big way."
"The tool does not provide CTI to monitor darknet."
"I want more support for regional compliance standards to serve my ANZ region customers better."
"I have yet to find the same capability in Wazuh to get logs from different sources into the system"
"A lack of certain features creates limitations."
"While it is scalable, it can suffer from reduced latencies."
"An issue I noticed is with tag values in certain rules not functioning properly."
"The tool doesn't detect anomalies or new environments."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The solution is open source, so it's free to use."
"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."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"We are using the community version, which can be used for free."
"The product price is neither too high nor too low."
"Wazuh is a good tool, but the open-source version has scalability limitations."
"The current pricing is open source."
"They have a good pricing strategy for market expansion."
"Wazuh is a cheaply priced product."
"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."
"Wazuh is open-source, so I think it's an option for a small organization that cannot go for enterprise-grade solutions like Splunk."
"There is not a license required for Wazuh."
