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 most valuable feature in AT&T AlienVault USM is the reporting."
"Every activity on the firewall is recorded, and notifications are sent with this solution."
"The IDS and the threat intelligence are very useful. They are very intuitive and data-rich."
"AlientVault has helped us in improving our visualization and incident response during cybersecurity situations."
"The most valuable feature is vulnerability management because it gives you insight into your environment to know what systems need to be updated or patched."
"The asset discovery and inventory capabilities in USM Anywhere is quite good."
"It allows you to define what alerts you want to see, or not to see, as well as if you want them grouped, or ungrouped."
"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.​"
 

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."
"Windows log collection works with HIDS, but documentation is sparse and confusing."
"There are scalability issues due to a 60 TB limit, which restricts its use for large customers like banks."
"Source material on the forums to be more up-to-date with the changes happening within the product. Forums being out-of-date with information due to the changes makes troubleshooting a little more difficult - specific to the HIDS agents."
"Its reporting tools need improvements. It would be good if they can provide integration with other ticketing systems. Currently, we only have integration with Slack and Jira. It is also a bit slow, and its replication engine can be improved."
"AlienVault needs to continue to integrate with other third-party technologies that clients want to have monitored."
"Their threat intelligence platform needs to be broadened. They should integrate it with more threat intelligence platforms. For the threat feed that they get from open intelligence, I would like them to add a few premium threat intelligence platforms. They can provide a bundle in which AlienVault has the threat intelligence background of other premium products."
"The AT&T AlienVault USM is okay, but the relational database is not very good for large amounts of data. For example, many logs cannot be processed. It has been very slow for the queries and some data which are large, it is not very good in this case."
"Pay attention to false-positive event automatic correlations."
 

Pricing and Cost Advice

"It’s a single license platform."
"The licensing fees are dependent on usage."
"AlienVault is flexible on their pricing for unlimited licenses."
"Negotiate the best package for your environment."
"It's very reasonably priced. It was one of the lowest among the ones I looked at. Licensing is pretty flexible. They can do a two-year or a three-year, even a one-year, perhaps."
"Do the one month trial and try to work out the kinks during it, as it has free support and service hours."
"I don't think the product's pricing is a good value because they try to raise the price 50 percent every year... AlienVault needs to understand that not all customers are huge enterprises... Their sales team is way too aggressive. The price they advertise is not always the price you get."
"I don't know exactly, but I know it is based on the number of logs and the retention duration, such as 30 days or something like that. So, the smallest package is about 500 a month for 30 days of logs. There is a virtual machine. You need resources for it. It is a log collecting VM. They provide the software, and you just have to load a virtual machine. So, you're going to incur some CPU RAM and storage for wherever this log collecting appliance is running, which typically is in our cloud and on our platform for the customer."
"So far, it has been a good solution for a tight budget."
