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.

Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.
