🔒 Title: Enabling Microsoft Defender for Endpoint + PCI-DSS Email Protection (UPYUGO Use Case)

 

We’re deploying Microsoft Defender for Endpoint and aligning it with PCI-DSS v4.0 compliance for our UPI-first fintech brand UPYUGO Technologies.

Our focus:

• Shield transactional emails (KYC, OTP, payment alerts)

• Lock down phishing/spam with custom quarantine logic

• Implement Defender strict policy + advanced anti-spam (MDO)

 

Would love feedback on:

• Best practices for Defender ATP in regulated environments

• DMARC, SPF, DKIM recommendations

• Log forwarding to Sentinel or Azure Monitor

 

Cheers,
