Helps to deal with potential attacks and is available at a reasonable price
My company has had many benefits from the use of the product in the last eight years. The tool has streamlined our company's incident response process since it serves as a log repository, which allows us to correlate events and access different technology stacks. In our company, we were able to actually find some potential attacks, so it has been very helpful. The tool's integration capability isn't so great. In my company, we managed to integrate it with our Microsoft Azure Subscription, after which we managed to integrate it with other tools. You will face a lot of difficulties if you want to integrate it with your database monitoring tool, PAM solutions, or IAM products. The product has done well overall for my company's teams to deal with their workflow efficiency. I would not recommend the product to others. I rate the tool a seven out of ten.

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

"Offers a good wireless feature."
"Technically speaking, this is a good product."
"Alerting Module: It provides real-time event processing language on all the logs/packets stream for advanced alerting, i.e., using SQL LIKE statements."
"The most valuable features are the packet inspection and the automated incident response."
"I can have enterprise security, email security, next generation firewall security log, HIDS and NIDS logs, etc. all on the same dashboard. It makes it easy to pinpoint or correlate our server to this. I can find out if there is lateral movement. This is the biggest advantage of this solution."
"It's quite economical compared to other solutions in the market."
"Prior to implementing the solution, the customers had no visibility of their assets, however, after adopting the solution, they have gained complete visibility over all their assets, including a comprehensive understanding of the network and attack symptoms."
"Incident management is its most valuable feature."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"We have encountered issues with unresolved crashes."
"The log system is a bit complex and has room for improvement."
"More customizability is required, which is something that they need to improve on."
"The product continues to crash. Even with tech support help, it does not resolve itself."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions."
"Its technical support could be better."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions. Whenever any hacking activity or any other threat factor occurred they used to provide the coverages very fast when comparing RSA NetWitness Logs and Packets. I heard the other three solutions, from a discussion with my team members who had experience in other solutions, they used to say that. Whenever any issues happened across the globe RSA NetWitness Logs and Packets are a little bit slow improving those detection mechanisms."
"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."
 

Pricing and Cost Advice

"Our license is for one year."
"This is a pricey solution; it's not cheap."
"It is cheap."
"Compared to the competition, the is price is not that high."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"We have yearly licensing costs. The license fee can be based on the volume of EPS. Some organizations may have, as a gentlemanly gesture, 10,000 EPS and get a 3,000 EPS license but actually use 5,000 EPS."
"The product is expensive."
"It’s a single license platform."
