We would like to bubble up alerts from Splunk to our alert management platform. I see there are a couple of options,   AWS SNS Topics, and a Webhook Alert. With either of those there is a security issue, as it would require  us to open an API or SNS Topic to the world. What I would like is in the case of SNS,  to know if there is an AWS Account or IP that I could restrict ingress?    For the webhook I guess it could only be an IP restriction from the splunk hosts. Also - if there is a better option / add-on available to increase security here I would be interested.  I just haven't found anything other than "Observability Cloud" which we do not have a license for.  Thanks!  ...
