From Zero to DMARC Enforcement — And Why It Was Worth It - CSA Live Webinar 2026

Steffen Siguda, CISO of ams OSRAM, will share what actually pushed them from "we should probably do SPF" to full enforcement of DMARC — the internal conversations, the pressure points, and what changed once it was live. Matia Boldrini from dmarcian puts that story in context, drawing on deployments already in the field: where DMARC projects typically stall (rarely a purely technical problem), and what a structured rollout actually delivers, strategically and operationally. We'll close with an open discussion between customer and provider perspectives, concrete lessons learned, and what's next for anyone planning their own rollout.
