Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"Easy to use, scalable, stable, and very intuitive platform that provides protection against security threats."
"The Event Correlation and vulnerability scans have been the most useful. As a 24/7 SOC, we use the incoming alarms to give an overview of suspicious traffic going through the network. It's easy to look at the correlated events and see the broad picture of traffic for that customer. Vulnerability scans are good for providing patch and remediation guidelines to keep customer systems secure."
"The new cloud-based panel is excellent both for client review as well as for our SOC to review and respond to threats. It is much easier to configure and use than the previous solution from AlienVault.​"
"There are multiple tools for information security. The solution includes all the latest advances on the network and host intrusion detection systems."
"On any given day I could give you a different answer regarding the most valuable features of the product. The feature that is most important is the fact that it has a lot of features, that it's not just a log collection and correlation system, that it has a lot of other components built in. The bundle of features is really the killer feature."
"The setup is very easy and straightforward."
"The AlienVault solution has enabled us to create a SOC on a budget with smaller than usual staff requirements, offering a wider range of solutions for our customers."
"Its powerful correlation engine helps reduce time in manually correlating events."
 

Cons

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
"AT&T AlienVault USM can improve searchable data. It should be available for more than 90 days. If you need more than 90 days of data, you have to put a request and they give you raw data, which is not easy to search. A good addition would be to allow users to search data older than 90 days."
"We've had some stability problems, not a lot, but a few. Updates seem to be the worst. That seems to be when the stability problems come up."
"The vulnerability reporting needs to have options to be able to sort or customize the output."
"Windows log collection works with HIDS, but documentation is sparse and confusing."
"Pay attention to false-positive event automatic correlations."
"Adding a parsing interface for the customers would make AT&T AlienVault USM better."
"The reporting aspect could be improved. While there are a lot of different options available, there are still pieces which are missing."
"I've been using it just for my own personal upskilling in terms of how the product works. At the moment, it is pretty straightforward and simple, and it is working how it is supposed to. The feedback would come once it is deployed to customer sites. They'll be using it on a more frequent basis, and that's when the feedback would come in terms of the areas in which they're facing issues or are looking for simplicity."
 

Pricing and Cost Advice

"It’s a single license platform."
"So far, I feel the product's pricing is a good value. The technology is decent. You get what you pay for. I think it's fair."
"Negotiate the best package for your environment."
"The pricing is a good value. The key thing is that for the new product, the licensing of it, is subscription-based and it's based on data. Clients need to be really careful when thinking about that, because odds are they're going to need to put a lot more data into it than what they initially estimate, which is going to drive their subscription costs up."
"Its price is in the medium to upper range."
"Its price is much lower than McAfee ESM."
"Use the AlienVault team. They are helpful and the documentation that they provide is second to none."
"It allows you to do a lot with a small price tag... The pricing is the best on the market."
"It has good pricing."
