@dmarcian.comTo combat fraud and identity theft, the Payment Card Industry (PCI DSS v4.0) now requires a layered anti-phishing strategy recommending #DMARC, #DKIM, and #SPF. Still working on it? We've created a go to resource with all you need to know: dmarcian.com/pci-requires... #PCIDSS
@dmarcian.comMost #DMARC projects don’t stall on #DNS; they stall on a person and who has no reason to answer your email’s request for help. AI won't fix human incentive problems or help you align teams. Getting an enterprise to p=reject takes a shift in mindset: dmarcian.com/dmarc-deploy...

@secuso.aifb.kit.edu✅ #DMARC ist ein Verfahren, das durch die Authentifizierung von Absender-Domains für weniger betrügerische E-Mails sorgen soll.
📈Die Ergebnisse zeigen einen starken Anstieg an neuen DMARC-Einträgen im Mai und Juni 2025, der sich möglicherweise auf Kommunikation des @bsi.bund.de zurückführen lässt.
@inboxplacementio.bsky.socialSPF, DKIM, DMARC alignment ensures sending domains match the From: header for DMARC authentication. Authentication results are factual but don’t guarantee inbox placement.
