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 initial setup was straightforward. I didn't have any problems."

"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."

"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."

"The product is majorly used for threat detection of the agents on servers and endpoints."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"I recommend it due to the experience of the people running it."

"Asset discovery is good."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

More AlienVault OSSIM pros

"The most valuable features are the modules and metrics."

"I like that the solution is on top of the Kubernetes stack."

"The log monitoring and analysis tools are great in addition to SIEM file activity monitoring."

"Overall, I rate Wazuh a nine out of ten."

"The product’s interface is intuitive."

"The most valuable feature of Wazuh is the ELK for doing an investigation."

More Wazuh pros

Cons

"I don't like to work on OSSIM because it is unpredictable."

"The incidence reporting could be better."

"The user interface could be improved."

"Sometimes technical issues take very long to get resolved."

"The documentation could be improved."

"The price of this solution is very high and it could be cheaper."

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

More AlienVault OSSIM cons

"Wazuh is missing many things that a typical SIEM should have."

"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."

"The implementation is very complex."

"Scalability is a challenge because it is distributed architecture and it uses Elastic DB. Their Elastic DB doesn't allow open source waste application."

"Scalability is a constraint in the on-prem version of Wazuh in terms of the volume of logs we can manage."

"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."

"There could be a hardware monitoring tool for the solution."

"The computing resources are consuming and do not make sense."

More Wazuh cons

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."

"The solution is open source, so it's free to use."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"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."

"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 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."

"AlienVault OSSIM is an open-source solution."

More AlienVault OSSIM pricing and cost advice

"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."

"Wazuh is open-source, so I think it's an option for a small organization that cannot go for enterprise-grade solutions like Splunk."

"Wazuh is open-source, therefore it is free. You can purchase support for $1,000 a year."

"Wazuh is not an expensive solution."

"When I contacted customer care, they mentioned bundling options, that I found to be overall affordable."

"The solution's pricing is very competitive."

"Wazuh is an open-source tool."

"It is a cost-effective solution."
