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

"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."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"The initial setup was straightforward."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think AlienVault has the best price-performance ratio."
"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," and the solution works well and allows me to have visibility into anomalous events."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"The most valuable feature is the flexible log for identifying security threats inside an application. Sentinel is very good at this."
"It provides real time security event analytics."
"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 native integration with out-of-the box format is hassle free and allows data to be used advantageously."
"If Sentinel is integrated with Identity Manager and User Application Portal, the solution runs simply perfect!"
"We can do advanced hunting queries and modify SQL queries to get desired results based on the rules triggering over the console."
"The stability is phenomenal and we never had any issues with downtime or even had to restart."
 

Cons

"Sometimes technical issues take very long to get resolved."
"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 price of this solution is very high and it could be cheaper."
"The documentation could be improved."
"The price of this solution is very high and it could be cheaper."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The incidence reporting could be better."
"Some functions look great but, in practice, some key limitations turn the process into something opaque."
"I would like to see a better reporting work structure on the dashboard."
"I would prefer to extend dashboards part and their functions in Web GUI version, so the charts could be for configurable."
"It is an ancient product."
"The dashboard and customer view should be improved."
"This product's connection to certain types of cloud systems could be improved."
"Documentation for security aspects could be improved. It is difficult to find clear information about encryption or risks that are addressed."
"Price is always a consideration, so the price would be nice if it were lower."
 

Pricing and Cost Advice

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