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.

File integrity monitoring has strengthened our data protection and supports compliance needs
I expected one thing from the dashboard in Wazuh. In ManageEngine, when you use ManageEngine, you can assign a unique ID to all employees. Then with the unique ID, if you search any unique ID in the dashboard itself, you can get the unique ID everywhere, including where the laptop has been logged in, when the logout happened, and what actions have been done for that unique ID. I expected the same in Wazuh, but whenever we want to check any monitoring activities for a specific person, we need to search for the endpoint and then get the endpoint details from our Active Directory or wherever we have the endpoint name stored in our resources, and then search for the endpoint to see the history for that specific endpoint only. This made a simple thing a bit complex. If we had a correlation of logs where I could just search one unique ID and then the unique ID pulls every system in a time-wise manner, that would be a great improvement I would suggest.

Quotes from Members

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

Pros

"The product is easy to use."
"AlienVault OSSIM's GUI is very user-friendly."
"Technical support is excellent; they are very helpful and responsive."
"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."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"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."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"We found the MITRE framework mapping and the agent enrollment service to be the most valuable features of Wazuh."
"Wazuh's most beneficial features for our security needs are flexibility, built-in rules, integration capabilities, and documentation."
"Other than that, it's a highly recommended product from our side, and we wish that this product had intel support."
"The most valuable features are the modules and metrics."
"Wazuh has very flexible and robust features."
"The reporting and attractive dashboard are the most valuable features."
"Overall, I rate Wazuh a nine out of ten."
"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."
 

Cons

"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."
"The user interface could be improved."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"I don't like to work on OSSIM because it is unpredictable."
"Lacking in depth of reporting."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"Wazuh needs more security and features, particularly visualization features and a health monitor."
"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."
"The tool doesn't detect anomalies or new environments."
"The only challenge we faced with Wazuh was the lack of direct support."
"The implementation is very complex."
"The lack of AI features is an issue at the moment in the industry."
"We would like to see more improvements on the cloud. They need better cloud integration."
"The tool does not provide CTI to monitor darknet."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is an open-source solution."
"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."
"The tool's licensing costs are yearly."
"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."
"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."
"Wazuh is a good tool, but the open-source version has scalability limitations."
"It is a cost-effective solution."
"The product is cheaper compared to other tools."
"Wazuh is not an expensive solution."
"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."
"The product price is neither too high nor too low."
"We use the free version of Wazuh."
"It is a free-of-cost solution."
