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.

Simple antivirus solution integrates well but could improve pricing and currency options
I don't really have experience working with these solutions. I promote them for our clients, but I don't work with them. I can't share my experience with these tools as I make assumptions about that. For both Adlumin and CrowdStrike, both confirm that they're scalable and enterprise-ready and all those kinds of things. We haven't had any specific problem with either of those. We just have a preference for which one we would prefer. If somebody says they want to use a different one from the one that we prefer, then we have to find reasons why they aren't. But scalability is not one of the reasons that one is better over the other. I don't really have advice for people that are looking into using Sentinel; just do your research across what is available. On a scale of one to ten, I rate Sentinel a seven.

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 majorly used for threat detection of the agents on servers and endpoints."
"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 very stable, and compared to QRadar and Splunk, it's very stable."
"Network traffic analysis is highly efficient."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"The most valuable feature is the logging capability."
"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 have deployed it widely because I find that it gives value for money."
"Sentinel gave us logs to tell us what's going right and wrong in your environment so we could secure the network."
"The most valuable feature is the flexible log for identifying security threats inside an application. Sentinel is very good at this."
"Sentinel has positively impacted my organization by improving monitoring significantly."
"It makes everything easier by automating some tasks and growing with our needs."
"The native integration with out-of-the box format is hassle free and allows data to be used advantageously."
"The solution's Kusto Query Language (KQL) execution time is pretty good."
"Transactional user information improves security, prevents fraud, and promotes best practices."
"Novell SIEM was my second technology of this kind."
 

Cons

"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 user interface could be improved."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"I would advise others to not implement it for any enterprise-level organization."
"The user interface needs to be friendlier across the board."
"AlienVault OSSIM gives unwanted notifications."
"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."
"GUI could be improved."
"It is an ancient product."
"I rate Sentinel a six out of ten for scalability."
"I would like to see a better reporting work structure on the dashboard."
"Creating a drag-and-drop dashboard or workbook in Sentinel is a little more complex compared to other tools like LogRhythm and IBM QRadar."
"The web interface needs to be improved, as it has a java-based way to call its controls."
"This product's connection to certain types of cloud systems could be improved."
"Price is always a consideration, so the price would be nice if it were lower."
"There is no integration in the web-side of the tool."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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."
"OSSIM is free."
"AlienVault OSSIM is an open-source solution."
"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 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."
"We receive a pricing discount because of our ongoing partnership with Micro Focus."
"Sentinel is moderately priced."
"The solution’s pricing is aligned with its competitors."
"Sentinel's slightly on the expensive side."
"We inquired about getting support from the vendor, Micro Focus, but the cost was very high."
"Sentinel is a subscription-based solution."
