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

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
"The USM is a work horse, no matter what devices or the number of logs we throw at it, the system processes them in real time, correlates the events, and alerts on only events that need human review."
"Log-monitoring and alerting enable us to know when things happen that we need to know about."
"Using the communication within the security device, it is easier to create plugins."
"The most valuable feature of this solution is security management for PCI DSS."
"Ease of deployment across various environments."
"The pricing is amazing and really cheap."
"We had used previous products and found AlienVault centralized the logging for our security."
"The solution also provides basic log storage options for periods of 15, 30, and 90 days."
 

Cons

"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"The reporting module could be a little easier to handle, as it requires quite some trial and error until you get the reports you want. Also, it would be great to have a graphical interface for the Network Intrusion Detection System's rule management."
"The UI and overall processes need a little bit more love. This shows in the error banners that come up when you select certain things. There isn't a day that goes by that the UI doesn't error out and I can't view events for an alarm."
"There could be some type of integration with our existing portal. We have our own customer portals, and it would be good if there was an integration so that our portal can provide reports. There could be some type of API into the AlienVault system with the USM system so that it is easy to show the customers high-level reports of the system through our portal."
"The vulnerability scanning feature is one of the areas where the product has certain shortcomings and needs to improve. The tool has vulnerability scanning, but it is not that efficient."
"The reporting and dashboards have room for improvement."
"The only complex area of the setup was writing the custom scripts."
"It would be hard for any legitimate MSSP to use it."
"Windows log collection works with HIDS, but documentation is sparse and confusing."
 

Pricing and Cost Advice

"It’s a single license platform."
"​The vulnerability management solution is worse than buying a Nessus Professional license.​"
"They charge a license based on the storage. ATT AlienVault USM is a less expensive solution than IBM QRadar."
"It is affordable, and it also has many features that the premium products such as ArcSight and QRadar have. It is a very good platform for a SIEM solution. Everything is included in the price."
"Pricing is very competitive with other products and you get much more functionality from AlienVault."
"We pay around $12,000 a year including storage."
"The price for this solution is very good, but since the features do not work the price is expensive."
"The ROI is quite good."
"Use the AlienVault team. They are helpful and the documentation that they provide is second to none."
