Score. Monitor. Enforce. Detect.

Four integrated capabilities covering the full domain security lifecycle — from initial posture assessment to active threat detection.

Score

100-point Domain Security Score across 9 dimensions. Know your posture at a glance and know exactly what to fix first.

Monitor

Aggregate DMARC reports processed automatically. See every sender — authorised, shadow IT, and attacker — in one place.

Enforce

Impact simulation, risk-classified remediation, and one-click DNS rollback. Move to p=reject without fear.

Detect

Lookalike domain monitoring, dangling DNS detection, and automated takedown orchestration.

Domain Security Score

A single number that tells you where you stand.

The Domain Security Score is a 100-point composite assessment across 9 dimensions of your email authentication and DNS security posture. Letter grades A–F, historical trend tracking, and industry benchmarking so you know not just your score, but whether you're improving.

A free score preview is available without an account at spoofsentry.com/tools.

DMARC Monitoring

See every sender. Understand every report.

Aggregate DMARC reports processed automatically. AI-powered sender classification identifies 26+ ESP providers so you know who is sending on behalf of your domains — not just an IP address.

Aggregate Report Processing

  • Automatic RUA report ingestion
  • SPF and DKIM alignment per sender
  • TLS-RPT failure reporting
  • Volume trend analysis

AI Sender Classification

  • 26+ ESP providers auto-identified
  • Shadow IT detection
  • Attacker traffic flagged
  • Sender inventory with risk labels

Continuous Monitoring

  • Real-time sender alerts
  • New source notifications
  • Branded digest emails
  • Email deliverability dashboard
Enforcement Center

From p=none to p=reject — without fear.

Most DMARC journeys stall at p=none because teams are afraid of blocking legitimate email. The Enforcement Center removes that uncertainty with impact simulation and instant rollback.

1

Simulate

Replay aggregate report data through an impact model — see exactly which senders would be blocked at p=reject before you flip the switch.

2

Remediate

Risk-classified sender inventory with guided remediation playbooks. Know which senders to fix, authorize, or remove before enforcing.

3

Enforce

Move from p=none to p=quarantine to p=reject at your own pace. One-click DNS push to Cloudflare, Route 53, Azure DNS, GoDaddy, and Google Cloud.

4

Rollback

If anything looks wrong post-enforcement, roll back to the previous policy in one click — with full audit trail.

One-click DNS rollback

Native integration with Cloudflare, Route 53, Azure DNS, GoDaddy, and Google Cloud DNS. Push or revert your DMARC policy directly from the console — no manual DNS editing required.

Threat Detection

Detect what your DNS doesn't tell you.

Domain spoofing goes beyond your own DMARC policy. SpoofSentry watches the broader threat surface — lookalikes, abandoned subdomains, and active spoofing campaigns — and acts on them.

Lookalike Domain Detection

Continuous monitoring for domains that impersonate your brand — typosquats, homoglyphs, and combo-squats — with automated takedown orchestration via Google Web Risk, Netcraft, and URLhaus.

Dangling DNS & SubdoMailing

Detect DNS records pointing to decommissioned services that attackers can claim. SubdoMailing detection identifies subdomains being abused for spam campaigns.

Spoofing Campaign Detection

AI-powered analysis of aggregate report data to surface active spoofing campaigns against your domains, with IP attribution and sender intelligence.

Integrations

Fits where your team already works.

25+ integrations for alerting, ticketing, SIEM ingestion, and PSA/RMM workflows. Webhooks for anything else.
