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

"The solution is free to use."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"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."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"Wazuh's most beneficial features for our security needs are flexibility, built-in rules, integration capabilities, and documentation."
"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."
"The most valuable feature of Wazuh is its EDR capabilities."
"It is a stable solution."
"Wazuh's best features are syscheck, its ability to immediately resolve vulnerabilities, and that it's open source."
"Wazuh offers an enhanced HDR version that outperforms its competitors."
"Wazuh is simple to use for PCI compliance."
"Good for monitoring, active response, and for vulnerabilities."
 

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The documentation could be improved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"Sometimes it takes very long for your issue to get resolved."
"AlienVault OSSIM gives unwanted notifications."
"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."
"The user interface needs to be friendlier across the board."
"They can add more compliance templates."
"Wazuh needs more security and features, particularly visualization features and a health monitor."
"An issue I noticed is with tag values in certain rules not functioning properly."
"The support channel is not optimal, and extensive research is required on our part to implement Wazuh effectively."
"It would be great if there could be customization for the decoder portion."
"There's not much I like about Wazuh. Other products I've used were a lot more functional and user friendly."
"Scalability is a challenge because it is distributed architecture and it uses Elastic DB."
"The support channel is not optimal, and extensive research is required on our part to implement Wazuh effectively."
"So far, the recent updates have addressed most challenges we previously faced."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"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 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 an open-source solution."
"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."
"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."
"The tool's licensing costs are yearly."
"My client uses the open-source version of Wazuh."
"Wazuh is an open-source tool, which means it is freely available for use."
"There is not a license required for Wazuh."
"It is a free-of-cost solution."
"The solution's pricing is very competitive."
"It is a cost-effective solution."
"They have a good pricing strategy for market expansion."
"Wazuh is open-source, so I think it's an option for a small organization that cannot go for enterprise-grade solutions like Splunk."
