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

"Network traffic analysis is highly efficient."

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."

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

"With AlienVault you get everything in one box."

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."

"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."

"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."

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

More AlienVault OSSIM pros

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

"The product's initial setup phase was easy."

"I like Wazuh because it is a lot like ELK, which I was already comfortable with, so I didn't have to learn from scratch."

"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."

"Wazuh's logging features integrate seamlessly with AWS cloud-native services. There are also Wazuh agent configurations for different use cases, like vulnerability scanning, host-based intrusion detection, and file integrity monitoring."

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

"It is a stable solution."

"My company implemented Wazuh because it was relatively inexpensive. They could quickly get their hands on it to check a box for some audit and compliance."

More Wazuh pros

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"The user interface could be improved."

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

"Lacking in depth of reporting."

"GUI could be improved."

"AlienVault OSSIM gives unwanted notifications."

"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."

More AlienVault OSSIM cons

"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."

"However, in the long term, if you want to build a SOC center on Wazuh, I do not recommend it because it's not stable."

"Wazuh requires substantial maintenance. The indexer frequently times out, requiring system restarts. When it comes to errors, debugging takes considerable time."

"Since it's an open-source tool, scalability is the main issue."

"A lack of certain features creates limitations."

"One area where Wazuh could use some improvement is in its reporting mechanism, especially for high-level management like CSOs and CEOs."

"Its configuration process is time-consuming."

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

More Wazuh cons

Pricing and Cost Advice

"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."

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

"We are using the community version, which can be used for free."

"AlienVault OSSIM is an open-source solution."

"OSSIM is free."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"The solution's cost is above the average."

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

"Wazuh is an open-source tool, which means it is freely available for use."

"They have a good pricing strategy for market expansion."

"The current pricing is open source."

"Wazuh is an open-source tool."
