We use Trellix Helix Connect because it is a SaaS solution. I think it has its own infrastructure rather than AWS or another provider. We use the Helix SaaS and a component called Evidence Collector that gets the logs from on-premise infrastructure and sends them to SaaS. I believe everything about Trellix Helix Connect is SaaS-based.
We use Evidence Collector which can be installed with the on-premise infrastructure to collect components such as files and IPS. This product receives the logs from the infrastructure and sends the information to Helix.
