Integration challenges highlight the need for manual workflows
The standard integrations are very limited, and the integrations available are not listed in the marketplace. Obtaining validation for integrations from Palo Alto takes around eight months, which is quite long. The solution would benefit from having more standard playbooks and templates available, as in other partners. Currently, everything must be created from scratch. In terms of incident response automation, it is quite poor due to the lack of integration with all security tools, making manual intervention necessary.

Senior Security Engineer at Valuepoint Systems
Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.
