Don’t get me wrong, glad to see the collaboration, but maybe it is because MTLS collaborates with everyone. Their software is designed to have plugins, not a created as a single product. Not all implementations require all connecting software to be installed (purchased). Sigma will do great, but it is a specialized software, not all implementations will need it.
