TL;DR

Leverage a Prometheus Exporter to send all your application security vulnerabilities from Snyk into Splunk.

Here are all the necessary links to get started:

• Snyk Exporter: https://github.com/lunarway/snyk_exporter
• Splunk OpenTelemetry Collector for Kubernetes: https://docs.splunk.com/Observability/gdi/opentelemetry/install-k8s.html#otel-install-k8s

The option that I am describing here is just one way to achieve this. There might even be a more straight forward option available that I started to describe in a more recent post. Please find an additional approach in my post Snyk Integration Capabilities with WebHooks - some examples.
