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 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."
"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 paid version of the solution has reporting and better scalability options."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"I have deployed it widely because I find that it gives value for money."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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 tool is simple to use."
"The solution's Kusto Query Language (KQL) execution time is pretty good."
"It makes everything easier by automating some tasks and growing with our needs."
"One of the most valuable features is the business intelligence engine; it's very important because it keeps track of everything that's happening and alerts us if something is different than expected."
"The solution lets us get all the logs properly and regularly monitor customer infrastructure."
"The correlation engine allows our clients to generate rules more efficiently."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"Transactional user information improves security, prevents fraud, and promotes best practices."
 

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"They can add more compliance templates."
"Sometimes technical issues take very long to get resolved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The documentation could be improved."
"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."
"AlienVault OSSIM is costly."
"The biggest thing I always complain about is that the user intake is a very old version."
"The dashboard and customer view should be improved"
"This product's connection to certain types of cloud systems could be improved."
"Frankly speaking, we did not find this product to be valuable, at all."
"The web interface needs to be improved, as it has a java-based way to call its controls."
"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"It is an ancient product."
"I would like to see a better reporting work structure on the dashboard."
"I rate Sentinel a six out of ten for scalability."
 

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."
"We are using the community version, which can be used for free."
"The tool's licensing costs are yearly."
"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 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 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."
"AlienVault OSSIM is an open-source solution."
"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 is a subscription-based solution."
"We inquired about getting support from the vendor, Micro Focus, but the cost was very high."
"Sentinel's slightly on the expensive side."
