The newsletter where an InfoSec Manager shares what actually happens behind the scenes

I'm Andries, a working InfoSec Manager. This newsletter is how I learn -- by writing about what I encounter on the job and sharing it with others in similar roles. No technical deep dives. No vendor pitches. Just real stories, honest mistakes, and practical lessons from someone sitting in the same chair as you.Published when there's something worth saying.
