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."
"Any unusual behaviour, we can monitor. We have alerts set up to be sent when we receive signs of any unusual behaviour."
"This solution can completely detect and prevent incidents on your network."
"The pricing is amazing and really cheap."
"The asset management functionality (active and passive scans) is also really important. You can't protect what you do not know about, so having an inventory of all your devices and software is critical to a security management program."
"AlientVault has helped us in improving our visualization and incident response during cybersecurity situations."
"We're using it more for reporting, that's all. We're using it to help our customers to pass any kind of audits that they receive."
"The dashboards are very descriptive and contain just the right amount of information. The activity alarms and events contain a plethora of data that is very descriptive and useful."
"Vulnerability scanning helped out shortcomings of what was not patched in the past and what needed to be patched. This assisted with fine tuning the environment for compliance."
 

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 dashboard could be improved as well as the level of customization."
"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."
"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."
"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."
"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."
"The other thing is the agent is OSSEC. They needed to create its own agent to help to find threats on the devices that it happens to be installed."
"AlienVault must improve their correlation feature. Some of the events do not match with the correlation rules and some of the correlation events are false-positive."
"USM Anywhere relies a lot on the community putting the data in. Often, you'll right-click on the attack, but nothing will be found. That's a weakness of it."
 

Pricing and Cost Advice

"It’s a single license platform."
"It's saved security costs."
"It allows you to do a lot with a small price tag... The pricing is the best on the market."
"It's affordable for most customers."
"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."
"We ran a few PoCs. The price and feature set were the best with AlienVault."
"We pay around $12,000 a year including storage."
"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."
"They are a little more expensive than Microsoft."
