BP
Independent Contractor at a comms service provider with 5,001-10,000 employees
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

"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."
"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."
"With AlienVault you get everything in one box."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"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."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"Wazuh is free and easy to use. It is also adjustable, and we can use it on the cloud and on-premises."
"Wazuh's most beneficial features for our security needs are flexibility, built-in rules, integration capabilities, and documentation."
"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."
"It's a simple solution you can try for free, and you can get support."
"The deployment is easy and they provide very good documentation."
"Stability-wise, Wazuh seems to have fixed all the past issues, and the latest version is possibly the most stable."
"It has efficient SCA capabilities."
"The MITRE ATT&CK correlation is most valuable."
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The price of this solution is very high and it could be cheaper."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"The user interface could be improved."
"Sometimes it takes very long for your issue to get resolved."
"The biggest thing I always complain about is that the user intake is a very old version."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"I would advise others to not implement it for any enterprise-level organization."
"Wazuh could improve the detection, it is not detecting all of the attacks. Additionally, it is lacking features compared to other solutions."
"Some features, like alerting, are complex with Wazuh."
"Since it's an open-source tool, scalability is the main issue."
"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."
"It would be great if there could be customization for the decoder portion."
"One area where Wazuh could use some improvement is in its reporting mechanism, especially for high-level management like CSOs and CEOs."
"I have yet to find the same capability in Wazuh to get logs from different sources into the system"
"There could be a hardware monitoring tool for the solution."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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."
"The solution is open source, so it's free to use."
"AlienVault OSSIM is an open-source solution."
"The tool's licensing costs are yearly."
"We are using the community version, which can be used for free."
"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."
"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."
"It is an open-source product."
"Wazuh is a cheaply priced product."
"The product price is neither too high nor too low."
"Wazuh is free and open source."
"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."
"They have a good pricing strategy for market expansion."
"The solution's cost is above the average."
"Wazuh has a community edition, and I was using that. It's free and open source."
