EMAIL IMPERSONATION SHIELD
DMARC & Anti-Phishing Security Checker
Prevent ransomware gangs and scammers from forging emails from your corporate domain.
Overview & Threat Landscape
Email spoofing and Business Email Compromise (BEC) account for over 80% of corporate ransomware infiltrations. Without an enforced DMARC policy (p=reject or p=quarantine), any cybercriminal on the internet can impersonate your executives and invoices.
Why Email Authentication is Critical
01
Ransomware Prevention
Attackers forge trusted supplier emails to deliver malicious payloads straight to employees' inboxes.
02
Invoice & CEO Fraud
Unprotected domains allow attackers to demand urgent bank transfers posing as your CEO or CFO.
03
Inbox Deliverability
Google and Yahoo now reject or quarantine emails from domains lacking proper DMARC and SPF alignment.
Standard Remediation Policy
Publish a TXT record at `_dmarc.yourdomain.com` with quarantine or reject enforcement:
_dmarc.yourdomain.com TXT "v=DMARC1; p=reject; sp=reject; pct=100; rua=mailto:[email protected]; aspf=r; adkim=r;"
