| Headquarters | Amsterdam, Netherlands | South San Francisco, California, United States |
| Purpose | NETCAP converts network packet streams into structured audit records for network analysis, security research, machine learning, and forensics. | Zui is a desktop application for querying and debugging Zed lakes. |
| Security | The download page says Pro analyzes captures locally on the user's machine and has no upload step. | The maker says Zui releases are signed with a code signing certificate to indicate the installer came from Brim Data and has not been tampered with since it was built. |
| Support | Pro includes email support, Enterprise offers priority support with an SLA, and Core lists community support. | The installation guide directs users who need help to troubleshooting documentation and the public Slack community. |
NETCAP suits network analysts, security researchers and forensic or machine-learning workflows that use packet captures. Core is available as an open-source CLI, while Pro adds investigation and analysis tools.
Zui suits people who need a graphical way to inspect Zed lake data or analyze packet captures. It is available on Linux, macOS, and Windows, though Linux updates require manual uninstalling and reinstalling.
