Capabilities

Everything in one place

From raw SPF breakdown to DMARC trend analytics — built to give engineers and security teams the full picture.

SPF Exposure & Alignment
Resolve every IP range authorised by your SPF records. See which ranges are actively used in DMARC events and which are dormant. Vendor-tagged via tbl_Vendor_SPF_Base.
Event Alignment IP Exposure Vendor History Change Log
DKIM Selector Management
Register, monitor and rotate DKIM selectors. Track pass rates per selector, surface unregistered selectors discovered in live DMARC events, and correlate selector changes with event trends.
Selectors Pass Rate History Coverage
DMARC Policy & Enforcement
Track policy progression from p=none through to p=reject. Per-domain grades, alignment mode, subdomain policy, pct and full change history.
