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.

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 tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"With AlienVault you get everything in one box."
"The initial setup was straightforward. I didn't have any problems."
"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."
"Network traffic analysis is highly efficient."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"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."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"Sentinel has positively impacted my organization by improving monitoring significantly."
"The solution's Kusto Query Language (KQL) execution time is pretty good."
"Sentinel gave us logs to tell us what's going right and wrong in your environment so we could secure the network."
"If Sentinel is integrated with Identity Manager and User Application Portal, the solution runs simply perfect!"
"The stability is phenomenal and we never had any issues with downtime or even had to restart."
"It makes everything easier by automating some tasks and growing with our needs."
"It provides real time security event analytics."
"In my opinion, Sentinel's best features include that it's a very easy product to use, it's very simple, and the after-sale service is very good."
 

Cons

"Sometimes it takes very long for your issue to get resolved."
"The price of this solution is very high and it could be cheaper."
"The user interface could be improved."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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 incidence reporting could be better."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"I would like to see a better reporting work structure on the dashboard."
"The dashboard and customer view should be improved."
"There is no integration in the web-side of the tool."
"This product's connection to certain types of cloud systems could be improved."
"You need a lot of Unix scripting knowledge in order to manage the tool, which is one of the main issues that we faced."
"Price is always a consideration, so the price would be nice if it were lower."
"Creating a drag-and-drop dashboard or workbook in Sentinel is a little more complex compared to other tools like LogRhythm and IBM QRadar."
"It's probably not a product that I would recommend to anyone."
 

Pricing and Cost Advice

"OSSIM is free."
"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 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."
"AlienVault OSSIM is expensive compared to its competitors."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is an open-source solution."
"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."
"Sentinel is moderately priced."
"We receive a pricing discount because of our ongoing partnership with Micro Focus."
"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."
"The solution’s pricing is aligned with its competitors."
