Featured Reviews

AKASH MAJUMDER - PeerSpot reviewer
Incident response times have significantly reduced with efficient device integration and log parsing capabilities
Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports. Additionally, a future update request is to enable tagging of endpoints in groups, similar to a feature available in Cortex XDR. The AI analytics need fine-tuning because some use cases are not working from my side.
Gaurav Ranade - PeerSpot reviewer
Excels at performing regression and correlation on the data
ArcSight is a legacy technology, and many customers want AI-powered technologies integrated with it. That hasn't been done yet, but ArcSight needs to catch up with the newer solutions and technologies available in the market. It can't just rely on the legacy technology from 2010 or 2012. You can't run that in 2024. It's a legacy technology with its own limitations. Customers often face issues that other software or newer solutions can resolve easily. That's the main challenge we face from customers right now. So, the only concerns are that AI needs to be integrated and scalability improved. Those are the main areas to be improved.
