PeelSec

Welcome to PeelSec: security, one layer at a time.

I'm Meni Tasa. I've worked in IT and security for about 12 years, from network specialist to head of IT and security. My goal is to help IT and security people, and developers, really understand the security they set up every day: so you can set it up right, fix it when it breaks, and explain it to others.

I teach identity and email security in plain words: single sign-on and SAML, passkeys, JWT, SPF, DKIM and DMARC, and certificates (PKI). Every word you need is explained first, every fact comes from the official source, and when it helps, you watch it happen in a small lab.

If you're setting up single sign-on, moving your team to passkeys, or fixing your company's SPF, DKIM and DMARC, I'm here to help.

Two kinds of videos:
• Courses take one topic from zero, chapter by chapter. Now: SAML 2.0. Next: PKI and certificates.
• Explainers answer one question people get wrong, in one video.
