BP
Independent Contractor at a comms service provider with 5,001-10,000 employees
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

"Technical support is excellent; they are very helpful and responsive."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"I have deployed it widely because I find that it gives value for money."
"What I like about this product, is that it is a fully-fledged solution."
"AlienVault OSSIM's GUI is very user-friendly."
"Network traffic analysis is highly efficient."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"We found the MITRE framework mapping and the agent enrollment service to be the most valuable features of Wazuh."
"It has efficient SCA capabilities."
"The product’s interface is intuitive."
"The most valuable feature of Wazuh is its EDR capabilities."
"Wazuh automatically scans the host for CIS benchmarks for the latest updates and vulnerabilities and gives a host score. It provides a percentage of perceived risk due to of non patches or any missing patches on that work."
"The tool is stable."
"It offers built-in modules for file integrity and vulnerability management."
"If they support a solution, it is easy to do an integration."
 

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The biggest thing I always complain about is that the user intake is a very old version."
"AlienVault OSSIM gives unwanted notifications."
"We need more dashboards and we need more customization for dashboards."
"The price of this solution is very high and it could be cheaper."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The correlation engine needs to be improved."
"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."
"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."
"Wazuh doesn't cover sources of events as well as Splunk. You can integrate Splunk with many sources of events, but it's a painful process to take care of some sources of events with Wazuh."
"The computing resources are consuming and do not make sense."
"One area where Wazuh could use some improvement is in its reporting mechanism, especially for high-level management like CSOs and CEOs."
"The tool does not provide CTI to monitor darknet."
"Wazuh has a drawback with regard to Unix systems. The solution does not allow us to do real-time monitoring for Unix systems. If usage increases, it would be a heavy fall on the other SIEM solutions or event monitoring solutions."
"Some features, like alerting, are complex with Wazuh."
"Wazuh should come up with more in-built rules and integrations for the cloud."
 

Pricing and Cost Advice

"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."
"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."
"AlienVault OSSIM is an open-source solution."
"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."
"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."
"We are using the community version, which can be used for 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."
"Wazuh is open-source, therefore it is free. You can purchase support for $1,000 a year."
"The solution's pricing is very competitive."
"The current pricing is open source."
"Wazuh is not an expensive solution."
"There is not a license required for Wazuh."
"Wazuh is an open-source tool, which means it is freely available for use."
"It is a cost-effective solution."
"Wazuh has a community edition, and I was using that. It's free and open source."
