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

"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"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."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"Better than other SIEM solutions because almost everything can be integrated."
"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 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."
"I recommend it due to the experience of the people running it."
"Wazuh offers numerous features, such as the ability to define custom rules for detecting malicious activities and remembering behaviors."
"Wazuh automatically scans the host for CIS benchmarks for the latest updates and vulnerabilities and gives a host score. It provides a percentage of perceived risk due to of non patches or any missing patches on that work."
"It's a simple solution you can try for free, and you can get support."
"The most valuable feature of Wazuh is the ELK for doing an investigation."
"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 best features are syscheck, its ability to immediately resolve vulnerabilities, and that it's open source."
"The product's initial setup phase was easy."
"The most valuable feature of Wazuh is its EDR capabilities."
 

Cons

"The user interface could be improved."
"The documentation could be improved."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"The incidence reporting could be better."
"The correlation engine needs to be improved."
"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."
"The user interface needs to be friendlier across the board."
"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."
"Wazuh is missing many things that a typical SIEM should have."
"Integration with Vyara could be better."
"Wazuh has a drawback with regard to Unix systems. The solution does not allow us to do real-time monitoring for Unix systems. If usage increases, it would be a heavy fall on the other SIEM solutions or event monitoring solutions."
"A lack of certain features creates limitations."
"The implementation is very complex."
"The deployment is a bit complex."
"There is room for improvement by integrating more AI into Wazuh. It requires constant nurturing, as I have to provide it with code and specific requirements."
"One area where Wazuh could use some improvement is in its reporting mechanism, especially for high-level management like CSOs and CEOs."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"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 expensive compared to its competitors."
"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."
"The tool's licensing costs are yearly."
"We are using the community version, which can be used for free."
"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."
"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."
"My client uses the open-source version of Wazuh."
"Wazuh is free and open source."
"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 totally free and open source. There are no licensing costs, only support costs if you need them."
"Wazuh is an open-source tool, which means it is freely available for use."
"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."
"Wazuh has a community edition, and I was using that. It's free and open source."
"Wazuh is a cheaply priced product."
