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.
Daniel Durian - PeerSpot reviewer
Helps to monitor and detect cyberattacks
The tool's effectiveness depends on how you define your log sources. To build visibility of incoming and outgoing traffic, you need logs from perimeter defense, firewalls, web application firewalls, and endpoint protection. With good traffic visibility, incident response time is really quick. Trellix ESM provides situation awareness. On the dashboard, I can see outbound and inbound communications to known threat hosts, IPS/IDS activity, and threat intelligence of the perimeter defense in the firewall. This information helps preempt attacks.
