What would you share in your newsletter?

So I'm working in the Cybersecurity field, as you know this topic has a lot of "hype" around it. It's every day almost, and everywhere in the media, big companies are getting hacked, and personal data are all over the internet. With my knowledge and my will to help people (and share) I wanted to create a newsletter about it.

So before starting that and selecting topics that might help people I wanted to know from some of you that might be interested. What would be the topics or subjects you would like to see in such a newletter ? and what would make you subscribe to it?

Thank you for your precious feedback. Hope this will help me accomplish that and hope I might be able to help people be more secure or maybe join the CyberSecurity field.

Cheers.
