I build cloud security for a living, and teach the rest of it in public.

Eight years securing cloud infrastructure, and the last few explaining what that work actually looks like. What began as notes to myself turned into a weekly newsletter, a course, a book, and an audience of more than 160,000 people trying to break into cyber security, or level up once they are in.

I host The X-Ops Brief at Sophos, write Cyber Notes every week, and build the practical training I wish had existed when I started.
