Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

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."
"AlientVault has helped us in improving our visualization and incident response during cybersecurity situations."
"In terms of monitoring, my best feature would be the monitoring of components across the network. It monitors the respective nodes and any new node that comes onto the network and provides reports. The reporting dashboards are really helpful for management in terms of making decisions around patch management."
"The most valuable feature of the solution is the ease of deployment that it provides to users. The integrations that the product has with third-party applications are useful."
"We are able to get alerts perfectly with FIM and VA features."
"The asset discovery and inventory capabilities in USM Anywhere is quite good."
"The ease of implementation is the most valuable feature."
"AlienVault provides a checklist answer when using SIEM."
"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."
 

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."
"Pay attention to false-positive event automatic correlations."
"For creating new rules, you have to be familiar with regular expressions. I feel there could be something built-in to make sure that process is easier."
"I want to see more compliance management capability. The quality of integrations seems to be a little bit low."
"There are scalability issues due to a 60 TB limit, which restricts its use for large customers like banks."
"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."
"The reporting and dashboards have room for improvement."
"The one thing I continue to dislike about the USM is the limitation on reports."
"The vulnerability reporting needs to have options to be able to sort or customize the output."
 

Pricing and Cost Advice

"It’s a single license platform."
"Negotiate the best package for your environment."
"Its price is in the medium to upper range."
"We checked out several competitors. For what it can do and the cost, it was the best option!"
"Pricing is very competitive with other products and you get much more functionality from AlienVault."
"​The price point is good.​"
"It's saved security costs."
"The ROI is quite good."
"AT&T AlienVault USM is an expensive solution and we pay for the license and the support separately. We paid for the license and support for three years."
