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

"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"The solution is free to use."
"With AlienVault you get everything in one box."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The product is easy to use."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"Wazuh offers an enhanced HDR version that outperforms its competitors."
"The reporting and attractive dashboard are the most valuable features."
"We use it to find any aberration in our endpoint devices. For example, if someone installs a game on their company laptop, Wazuh will detect it and inform us of the unauthorized software or unintended use of the devices provided by the company."
"The main thing I like about it is that it has an EDR."
"The product is easy to customize."
"The product’s interface is intuitive."
"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's very easy to integrate Wazuh with other environments, cloud applications, and on-prem applications. So, the advantage is that it's easy to implement and integrate with other solutions."
 

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The initial setup was not so easy, partly because the documentation was not up to date."
"Sometimes it takes very long for your issue to get resolved."
"GUI could be improved."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"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."
"The user interface needs to be friendlier across the board."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"The tool doesn't detect anomalies or new environments."
"The product's configuration part and lack of AI capabilities are some of the major concerns associated with Wazuh."
"Its user interface for sure can be improved. It is not so comfortable to use if you're looking for specific logs."
"I want more support for regional compliance standards to serve my ANZ region customers better."
"When we use low-end laptops for low-level employees, then the laptops become slow because of the backend work the agent is collecting and processing, causing the laptop to slow down and the bandwidth to decrease."
"Integration with Vyara could be better."
"It would be better if they had a vulnerability assessment plug-in like the one AlienVault has. In the next release, I would like to have an app with an alerting mechanism."
"An issue I noticed is with tag values in certain rules not functioning properly."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"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."
"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."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"The tool's licensing costs are yearly."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"Wazuh is a good tool, but the open-source version has scalability limitations."
"The product is cheaper compared to other tools."
"Wazuh is a cheaply priced product."
"They have a good pricing strategy for market expansion."
"It is a free-of-cost solution."
"The solution's pricing is very competitive."
"Wazuh is open-source, therefore it is free. You can purchase support for $1,000 a year."
"When I contacted customer care, they mentioned bundling options, that I found to be overall affordable."
