# Managed DMARC & Email Authentication Enforcement

> From $3.5K · Cloud & Application Security · https://cisomarketplace.services/services/managed-dmarc-email-authentication

Spoofed email is how business email compromise starts, and mailbox providers now require authentication from bulk senders. We inventory every service sending as your domains, fix SPF, DKIM and alignment, move DMARC from monitoring to quarantine to reject in controlled steps, and then monitor it so a new marketing tool does not quietly break it.

## In scope

- Sender inventory across every domain and subdomain
- SPF, DKIM and alignment remediation
- Staged DMARC policy rollout: none, quarantine, reject
- Parked-domain protection
- Ongoing monitoring and new-sender onboarding

## Deliverables

- Sender inventory
- DMARC enforcement at p=reject
- Runbook for onboarding new mail senders
- Monthly monitoring report (managed tiers)
