Hey, we have a ton of resources that we try to share widely, so happy to have a look. I'm guessing you want to keep your basic guide short and pithy? E.g try to keep it to single sentences etc...
Happy to have a look at what you got tomorrow morning.
For a normal threat model user, it's hard to fault an iPhone these days, especially compared to the cluster*ck that is Android security updates.
However, most of the stuff we have written about in both the online trainings and Umbrella is for Android. Mostly because it is by far the most prominent platform for the major of countries that have the highest prominence of security threats to citizens, activists, journalists, aid workers etc.
I'd also recommend reading Troy Hunt's blog regularly. It's especially helpful for keeping up with whether account information on any site has been compromised. Look up his tool "have i been pwned"
Hey, thanks to everyone for the kind upvotes. Hopefully it will be useful. For those who somehow don't already know, we also build a free, open source, android app with tons of guides on digital and physical security - called Umbrella. We are currently doing an update of content and features (more at www.secfirst.org)
Available on Google Play, Amazon, F-Droid Repo etc:
We built the videos on providers platform, so a little out of our hands. But Alec Muffet has done loads on making it easier to spin up Tor hidden services - so I might reach out and see can we make that happen for them.
