Reliable and good support but can be expensive
I have no real complaints about the solution. Threat detection could be better. They need to enhance their threat intelligence feeds. We would like to have more IOCs or more trade intelligence to not only rely on the intelligence of the engineer in charge but to have some threat intelligence and some seeds of IOCs and to have the host have some artificial intelligence to reduce the number of false positives. I don't see this solution being very scalable. The solution is pricey.

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

"This solution allows us to locate the malware in real-time."
"It is stable. We have been using it for some time, without any issues."
"It is very easy to use, and its usability is great. The use cases are also very easy. The visualizations of the use cases are magnificent. You cannot find this in any other solution. From my point of view, it is great."
"The most valuable feature is the way it captures the traffic, and it contains every detail of the communication."
"The log correlation is good."
"RSA NetWitness does market analysis in a more granular form. It gives you full visibility."
"It's a scalable solution. We have around five to eight customers using RSA NetWitness Endpoint, and we hope to increase the number of users."
"It helps our security team respond more accurately when there are threats, then we get less false positives or negatives."
"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

"Its price could be improved. It is an expensive product. Its training is also too expensive. It would be great if they can have a better pricing scheme for the training."
"RSA NetWitness Network could improve on integration with non-native application integration."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"The deployment process is complex. I don't know why, but this solution will suddenly stop working. Logs stop coming. Often, one thing or another stops working. Most of the time, one of my team members is working with troubleshooting and working with technical support. Log passing is also one of the biggest challenge."
"The solution is modular, for example you can buy the RSA ePack, which you buy as a module is not part of the conduit solution. They could include it and have it as an all-in-one solution."
"The integration of the solution needs to be improved. The dashboard needs lots of updates as well. In the next release, we would like to see advanced fraud detection features."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
"The solution lacks a reporting engine."
"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

"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."
"It is highly scalable. It can be bought based on your requirements."
"They can easily adjust if you have the requirements which are required. If you have a budget cut or a budget constraint, they can bend."
"I do not have any opinion on the pricing or licensing of the product."
"It is an expensive product."
"The pricing is not very economical. It is a quite costly product for India. One thing is that when you purchase it, you have to purchase a module separately."
"With RSA, there is flexibility in choosing the service, products, and the range that meets your requirement, as well as they are flexible in terms of pricing."
"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."
"It’s a single license platform."
