Free Email Diagnostic ScannerThe Problem: Why p=none Blocks Zero Attacks
Your domain has a DMARC record published, but the policy is set to p=none. This means your IT team explicitly told the world's email systems: "If someone fakes our domain, don't stop the email. Just let it through."
The Mechanics of DMARC Monitoring (p=none)
A p=none policy is designed purely for the initial discovery phase of an email security rollout. It tells receiving servers (like Gmail, Microsoft 365, or Yahoo) to deliver failing emails to inboxes normally, but to send an XML aggregate report back to your IT team about the failure.
The problem is that many IT providers set up p=none to get the "green checkmark" on a basic audit, but never return to actually complete the rollout. Leaving a domain at p=none permanently provides exactly zero protection against exact-domain spoofing, CEO fraud, and invoice redirection scams.
p=quarantine or p=reject.
Why Organizations Get Trapped in Monitoring Mode
The primary reason 70%+ of business domains remain frozen at p=none is the fear of breaking legitimate business email. Business owners and IT managers worry that if they aggressively switch to p=reject, invoices sent through QuickBooks, marketing blasts from Mailchimp, or customer notifications from their CRM will fail SPF/DKIM alignment and get dropped by client mail servers.
Additionally, raw DMARC aggregate reports (sent via rua=mailto:...) generate thousands of dense, unreadable XML files every single week. Without an automated platform to ingest and parse these reports, managing DMARC manually is nearly impossible for busy IT teams.
The Solution: Enuclea Hosted DMARC & The Safe 3-Phase Journey
Enuclea provides Hosted DMARC to completely eliminate the fear and friction of moving from passive monitoring to full cryptographic rejection (p=none → p=reject):
How Hosted DMARC Removes the Pain:
- Automated Visual Reporting: We ingest and aggregate all global XML feedback, turning thousands of lines of raw telemetry into a clear visual dashboard of authorized vs. unauthorized sending sources.
- Zero-Touch DNS Management: With Hosted DMARC, your policy is delegated once via CNAME. You never have to edit complex DNS TXT records manually every time your team adopts a new cloud tool.
- Guaranteed Sender Identification: We identify and cryptographically sign (DKIM) every legitimate shadow tool—from ADP and Stripe to Salesforce and Google Workspace—before applying enforcement.
- Phased, Safe Ratcheting: We guide your domain through a controlled transition:
p=none (Discovery)→p=quarantine (Containment)→p=reject (100% Spoof Protection)with zero legitimate emails dropped.
