I don’t have the literal list of websites for you to research on but I recommend:
- Privacy Guides
- Techlore videos
- The New Oil videos and The New Oil blog
- Naomi Brockwell videos
- Proton blog
About a full day research from the aforementioned websites/content will EASILY give you enough to speak about it for 3 mins. I don’t know how old you are or how much experience you have with public speaking but 3 mins will FLY so you should have plenty to speak on just from one of those resources.
There are many other great resources that I may not be remembering as I write this. But I hope others add on too, to help out.
