This is a site which hosts a list of talks from various conferences on the topic of cloud native security. You can find a list of conferences on the sidebar to the left, or you can look in the categories section.
There’s also a search page (click the magnifying glass in the top right) which will search the abstracts of all the talks.
If you’d like to add a talk to the site, the GitHub site is here and there’s notes there on how to do it.
