I really enjoy @zackwhittaker's weekly newsletter, this week in security, because:
1. It's written at a level I can understand, as person somewhat tech savvy but certainly far from a security expert.
2. It's not on Substack! It was on MailChimp but just moved to Ghost.
3. Each newsletter ends with a cyber cat.
Good stuff; check it out if you're at all interested in security news.
