Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Argo CD

  • Licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare
  • The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly

Splunk Enterprise Security

  • Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
  • Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
  • UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
  • The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price
