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

"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."

"The solution is very stable, and compared to QRadar and Splunk, it's very stable."

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

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

"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."

"The solution is free to use."

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

"Asset discovery is good."

More AlienVault OSSIM pros

"It's very easy to integrate Wazuh with other environments, cloud applications, and on-prem applications."

"The MITRE ATT&CK correlation is most valuable."

"The configuration assessment and Pile integrity monitoring features are decent."

"It is a stable solution."

"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 main thing I like about it is that it has an EDR."

"It is excellent in terms of visualization and indexing services, making it a powerful tool for malware detection."

"Integrates with various open-source and paid products, allowing for flexibility in customization based on use cases."

More Wazuh pros

Cons

"The correlation engine needs to be improved."

"GUI could be improved."

"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."

"The correlation engine needs to be improved."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"The initial setup was not so easy, partly because the documentation was not up to date."

"The solution needs more integration with cyber intelligence systems."

More AlienVault OSSIM cons

"Wazuh doesn't have native support for some enterprise solutions."

"I have yet to find the same capability in Wazuh to get logs from different sources into the system"

"The deployment is a bit complex."

"Adding the flexibility to integrate various plug-ins or modules into its core system would enhance functionality."

"The support channel is not optimal, and extensive research is required on our part to implement Wazuh effectively."

"Wazuh could improve the detection, it is not detecting all of the attacks. Additionally, it is lacking features compared to other solutions."

"I think that the next release should be more suitable for large enterprises, because currently they are not because large companies do not rely on open source solutions."

"Scalability is a challenge because it is distributed architecture and it uses Elastic DB."

More Wazuh cons

Pricing and Cost Advice

"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."

"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."

"AlienVault OSSIM is expensive compared to its competitors."

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

"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."

"OSSIM is free."

"The tool's licensing costs are yearly."

"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."

More AlienVault OSSIM pricing and cost advice

"Wazuh is free and open source."

"It is a free-of-cost solution."

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

"The solution's pricing is very competitive."

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

"Wazuh is a cheaply priced product."

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

"There is not a license required for Wazuh."
