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

"I have deployed it widely because I find that it gives value for money."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"You can customize the dashboards as well as the reporting."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"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."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"Wazuh's logging features integrate seamlessly with AWS cloud-native services. There are also Wazuh agent configurations for different use cases, like vulnerability scanning, host-based intrusion detection, and file integrity monitoring."
"Other than that, it's a highly recommended product from our side, and we wish that this product had intel support."
"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."
"It offers built-in modules for file integrity and vulnerability management."
"It's a simple solution you can try for free, and you can get support."
"The reporting and attractive dashboard are the most valuable features."
"Wazuh offers numerous features, such as the ability to define custom rules for detecting malicious activities and remembering behaviors."
"I like Wazuh because it is a lot like ELK, which I was already comfortable with, so I didn't have to learn from scratch."
 

Cons

"I would advise others to not implement it for any enterprise-level organization."
"ArcSight works better than AlienVault right now."
"The biggest thing I always complain about is that the user intake is a very old version."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"Lacking in depth of reporting."
"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."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The tool does not provide CTI to monitor darknet."
"Its configuration process is time-consuming."
"Wazuh needs more security and features, particularly visualization features and a health monitor."
"There is room for improvement by integrating more AI into Wazuh. It requires constant nurturing, as I have to provide it with code and specific requirements."
"It would be great if there could be customization for the decoder portion."
"When I face a challenge, I prefer not to spend too much time on it and may move to another solution that will give us the results."
"A more structured approach, perhaps with modular UI components, to facilitate easier integration and navigation within the Wazuh platform for custom integrations would be beneficial."
"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."
 

Pricing and Cost Advice

"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."
"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 an open-source solution."
"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."
"OSSIM is free."
"AlienVault OSSIM is free."
"Wazuh is open-source, but you must consider the total cost of ownership. It may be free to acquire, but you spend a lot of time and effort supporting the product and getting it to a point where it's useful."
"When I contacted customer care, they mentioned bundling options, that I found to be overall affordable."
"Wazuh is free and open source."
"Wazuh has a community edition, and I was using that. It's free and open source."
"Wazuh is a good tool, but the open-source version has scalability limitations."
"The solution's pricing is very competitive."
"They have a good pricing strategy for market expansion."
"It is an open-source product."
