Secure records still drift
Provider changes, migrations, inherited DNS, and routine administration can weaken email authentication long after the original configuration was approved.
Continuously validate critical controls
- SPF
- DMARC
- DKIM alignment
- DMARC RUA and RUF reports
- DNSSEC
- Blacklist status
Email security records rarely fail all at once. They drift.
MXSignet receives DMARC aggregate and forensic reports while continuously checking the public controls and reputation signals that determine whether your domains can be trusted.
Point-in-time checks age quickly
A clean assessment only describes one moment. It does not show when a DMARC policy changes, DNSSEC breaks, or a domain appears on a blacklist later.
Domain coverage is easy to miss
Primary, secondary, and newly introduced domains can carry email risk even when security teams are only watching the organization's best-known domain.
Know when trusted email posture changes.
MXSignet combines DMARC report receipt, domain discovery, deep record validation, blacklist monitoring, and change history so teams can distinguish real drift from unchanged configuration.
Discover the domain footprint
Inventory primary and secondary domains from company profiles so teams can expand monitoring without collecting credentials or maintaining a manual list.
Start with broader coverage
Validate authentication controls
Continuously check MX and DNS security posture, including SPF, DMARC policy, DKIM alignment inference, and DNSSEC configuration.
Know which controls hold
Receive DMARC reports centrally
Use the reporting address provided during MXSignet setup as the DMARC RUA and RUF destination so aggregate and forensic reports are received in one place.
Centralize DMARC reporting
Monitor blacklist exposure
Track email infrastructure against more than 100 industry-standard and premium blacklist providers to surface reputation and compromise concerns.
See reputation risk early
Establish a clean baseline
Record the accepted configuration on first review and preserve historical snapshots so teams can distinguish known posture from unexpected change.
Define the trusted state
Detect meaningful drift
Compare new scan results against the baseline and highlight changes such as DMARC policy shifts instead of repeatedly alerting on unchanged records.
Reduce alert fatigue
Keep remediation in context
Give IT and security teams the affected domain, record state, change history, and validation result needed to investigate and restore secure posture.
Move from signal to action
Turn public DNS into continuous assurance.
Replace occasional manual checks with a repeatable monitoring cycle that preserves the expected state and makes material changes easier to investigate.
Discover
Identify the primary and secondary domains that make up the organization's public email footprint.
Collect
Route DMARC reports to the MXSignet-provided address, then check authentication, DNS security, mail routing, and blacklist status.
Baseline
Establish the accepted record state and retain structured snapshots for future comparison and compliance history.
Monitor
Repeat validation continuously and separate material configuration changes from records that remain unchanged.
Respond
Review drift or reputation findings with the domain context and history needed to assign and verify remediation.
Protect trust in every domain.
MXSignet gives IT and security teams a current, defensible view of email authentication, DNS posture, reputation, and configuration history across the organization's domain footprint.
