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."

"The main menu: You can see everything there, what is happening on the servers, and in the logs, you can view more details of each event."

"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."

"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."

"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."

"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."

"Using the communication within the security device, it is easier to create plugins."

"I can easily check (in one place) all the logs and data in relation to attacks. It also gives me an overview if a server is not configured properly."

"The solution also provides basic log storage options for periods of 15, 30, and 90 days."

More USM Anywhere pros

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 tools are a bit lacking for building reports to give directly to customers, but support has been helpful in giving our requests for new features to the development team and following up with us."

"Different functions to customize reports should be added."

"Support can be slow at times, but the quality is high. Posted knowledge base articles could use improvement."

"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."

"There are scalability issues due to a 60 TB limit, which restricts its use for large customers like banks."

"The reporting is mediocre and is something that needs to be improved."

"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."

"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."

More USM Anywhere cons

Pricing and Cost Advice

"It’s a single license platform."

"QRadar, ArcSight and Splunk are some of the most expensive SIEM products out there in the market and not everyone has the budget to buy them. In such cases, AV USM is a very cost effective alternative."

"I rate the price of AT&T AlienVault USM a four out of five."

"It is a product that is priced in a medium range, making it neither a cheap nor a costly product."

"Its price is much lower than McAfee ESM."

"The vulnerability management solution is worse than buying a Nessus Professional license."

"The price of this solution is reasonable, which is one of the reasons why we selected it over other solutions."

"The ROI is quite good."

"Use an MSSP instead. It is much cheaper."
