DMARC Monitoring Software
Collect and analyze DMARC aggregate reports, identify every sender using your domain, and move toward enforcement with the confidence that legitimate mail stays protected. SpoofSentry goes beyond report dashboards — combining sender classification, enforcement simulation, and domain posture scoring into a single platform.
Why monitoring alone is not enough
Most DMARC tools stop at showing you aggregate report data. That is visibility — not protection. Visibility without a path to enforcement leaves your domain at p=none indefinitely, which means spoofed mail still reaches recipients.
Effective DMARC monitoring must include sender discovery, classification, and a safe enforcement workflow. Otherwise you are collecting data you never act on. The gap between monitoring and enforcement is where most deployments stall — and where attackers continue to exploit unprotected domains.
Sender discovery and classification
When you publish a DMARC record, receiving mail servers report back every IP that sends email as your domain. The challenge is not collecting these reports — it is making sense of them. Most organizations have dozens of sending sources: transactional email providers, marketing platforms, CRM tools, helpdesk systems, and internal infrastructure.
SpoofSentry automatically identifies sending services (Google Workspace, Microsoft 365, SendGrid, Mailchimp, HubSpot, and hundreds more) from source IPs, classifies them by authorization status, and flags unknown senders that need investigation. This turns raw XML into an actionable sender inventory — the foundation for safe enforcement decisions.
Enforcement simulation and rollback
Moving from p=none to p=quarantine or p=reject is the highest-risk step in DMARC deployment. If a legitimate sender fails alignment, their mail goes to spam or gets dropped. The business impact can be immediate — missed invoices, lost customer communications, broken onboarding flows.
SpoofSentry lets you simulate enforcement — preview exactly which senders would pass and fail at quarantine or reject — before changing your DNS record. If something goes wrong after tightening policy, rollback recommendations help you revert safely. See the guided enforcement workflow and the quarantine vs reject guide for details on the process.
Domain posture scoring
DMARC is one component of domain trust. A passing DMARC check does not mean your domain is secure — it means one layer is configured. SpoofSentry evaluates your domain across email authentication (SPF, DKIM, DMARC), transport security (MTA-STS, TLS-RPT), DNS trust (DNSSEC, DANE), and hidden risk (dangling DNS records, subdomain takeover exposure).
The Domain Security Score gives you a single metric that reflects your overall posture — not just whether you have a DMARC record. Track score changes over time as you remediate findings and tighten policy.
Multi-domain and MSP support
Organizations with multiple domains and MSPs managing client portfolios need more than single-domain dashboards. Managing enforcement across 50 or 500 domains requires portfolio-level visibility, per-domain tracking, and the ability to identify which domains are ready for enforcement and which need more work.
SpoofSentry supports multi-tenant management, per-domain enforcement tracking, branded client reporting, and portfolio-level visibility. Whether you are managing 5 domains or 500, the workflow is the same. See the MSP solution for details on multi-tenant capabilities.
What you get on every plan
Every SpoofSentry plan includes DMARC aggregate report collection and parsing, sender identification and classification, SPF/DKIM/DMARC validation, enforcement readiness scoring, and access to 16 free diagnostic tools.
Paid plans add continuous monitoring, historical trends, enforcement simulation, multi-domain management, alerting, and API access. See pricing for plan details and a full feature comparison.
Frequently asked questions
How does DMARC monitoring work?
When you publish a DMARC record with a RUA address, receiving mail servers send you aggregate XML reports describing who sent email as your domain and whether authentication passed. A monitoring platform collects, parses, and visualizes these reports so you can identify senders and track alignment.
Do I need DMARC monitoring if I'm already at p=reject?
Yes. Even with reject enforcement, monitoring tells you if legitimate senders are being blocked, if new services need authorization, and if spoofing attempts are targeting your domain. DMARC is ongoing operations, not a one-time setup.
How is SpoofSentry different from other DMARC tools?
SpoofSentry combines DMARC monitoring with domain posture scoring, dangling DNS detection, enforcement simulation, and DNSSEC/DANE visibility. Most tools focus only on DMARC reports. SpoofSentry covers the broader domain trust surface.
Can I use SpoofSentry for multiple domains?
Yes. All paid plans support multiple domains with per-domain enforcement tracking. MSP and enterprise plans add multi-tenant management, branded reporting, and portfolio dashboards.
Is there a free tier?
Yes. SpoofSentry offers free DMARC validation, SPF/DKIM checking, and domain scoring tools. Paid plans start with continuous monitoring and sender classification.
How long does it take to set up?
Publishing a DMARC record takes minutes. Reports start arriving within 24-48 hours. Most organizations have a clear sender picture within 2 weeks.
Does SpoofSentry integrate with my existing tools?
SpoofSentry supports SIEM integration (Splunk, Elastic, Sentinel, Datadog), PSA/RMM integration for MSPs, and API access for automation.
