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 product is easy to use."

"You can customize the dashboards as well as the reporting."

"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

"Asset discovery is good."

"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

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

"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."

More AlienVault OSSIM pros

"It's very easy to integrate Wazuh with other environments, cloud applications, and on-prem applications. So, the advantage is that it's easy to implement and integrate with other solutions."

"I like the cloud-native infrastructure and that it's free. We didn't have to pay anything, and it has the capabilities of many premium solutions in the market. We could integrate all of our services and infrastructure in the cloud with Wazuh. From an integration point of view, Wazuh is pretty good. I had a good experience with this platform."

"It is a stable solution."

"The deployment is easy and they provide very good documentation."

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

"I would recommend Wazuh to others."

"If they support a solution, it is easy to do an integration."

"Regarding Wazuh, I find the SCA (Security Configuration Assessment) features most valuable. It's crucial for asset management and inventory, allowing us to monitorendpoints and servers' changes easily. This is particularly important for my customers, who aren't heavily focused on incident response but rely on asset management and inventories. Wazuh's compliance management features are very supportive, especially in regions like the Americas and Europe. However, it's less effective in the ANZ (Australia and New Zealand) region since Wazuh doesn't cater to the specific compliance standards there, such as those required in Australia. I appreciate that Wazuh fully complies with PCI DSS and GDPR standards, allowing us to generate necessary reports."

More Wazuh pros

Cons

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

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

"The user interface needs to be friendlier across the board."

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

"Lacking in depth of reporting."

"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 initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."

More AlienVault OSSIM cons

"Integration with Vyara could be better."

"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."

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

"So far, the recent updates have addressed most challenges we previously faced."

"They need to go towards integrating with more cloud applications and not just OS like Windows and Linux."

"Wazuh needs more security and features, particularly visualization features and a health monitor."

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

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

More Wazuh cons

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."

"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 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."

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

"The tool's licensing costs are yearly."

"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 an open-source solution."

More AlienVault OSSIM pricing and cost advice

"Wazuh is a good tool, but the open-source version has scalability limitations."

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

"The product is cheaper compared to other tools."

"It is an open-source product."

"We use the free version of Wazuh."

"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."

"The product price is neither too high nor too low."

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