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

"With AlienVault you get everything in one box."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"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."
"Technical support is excellent; they are very helpful and responsive."
"AlienVault OSSIM's GUI is very user-friendly."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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."
"The initial setup is straightforward."
"It is excellent in terms of visualization and indexing services, making it a powerful tool for malware detection."
"Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs."
"It offers built-in modules for file integrity and vulnerability management."
"The most valuable feature of Wazuh is the ELK for doing an investigation."
"Wazuh is a powerful tool, and you can do lots of things with it."
"Good for monitoring, active response, and for vulnerabilities."
"We found the MITRE framework mapping and the agent enrollment service to be the most valuable features of Wazuh."
"The product's initial setup phase was easy."
 

Cons

"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."
"I don't like to work on OSSIM because it is unpredictable."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The biggest thing I always complain about is that the user intake is a very old version."
"We need more dashboards and we need more customization for dashboards."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"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."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"Log data analysis could be improved. My IT team has been looking for an alternative because they want better log data for malware detection. We are also doing more container implementation also, so we need better container security, log data analysis, auditing and compliance, malware detection, etc."
"We would like to see more improvements on the cloud. They need better cloud integration."
"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."
"The tool doesn't detect anomalies or new environments."
"Its user interface for sure can be improved. It is not so comfortable to use if you're looking for specific logs."
"They need to go towards integrating with more cloud applications and not just OS like Windows and Linux."
"Since it's an open-source tool, scalability is the main issue."
"The support team could be more responsive and provide quicker replies during our working hours in Indonesia, which would be a significant improvement."
 

Pricing and Cost Advice

"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 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."
"OSSIM is free."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is an open-source solution."
"The solution is open source, so it's free to use."
"Wazuh is an open-source tool, which means it is freely available for use."
"Wazuh is not an expensive solution."
"The product price is neither too high nor too low."
"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."
"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."
"Wazuh is open-source, so I think it's an option for a small organization that cannot go for enterprise-grade solutions like Splunk."
"They have a good pricing strategy for market expansion."
"When I contacted customer care, they mentioned bundling options, that I found to be overall affordable."
