DMARCDrill

DMARCDrill is a web app (traditional + AI) that turns messy DMARC adoption into a controlled, auditable rollout. It ingests DMARC aggregate reports (RUA), normalizes data across major receivers, and shows exactly which senders will break when you move from p=none to quarantine/reject. The product’s core is a “policy simulator” that estimates impact per domain, subdomain, and sending source, then generates step-by-step remediation tasks (SPF alignment, DKIM selector fixes, third‑party sender setup). An AI assistant drafts vendor-specific instructions and change tickets, but the app keeps humans in control with explicit approvals and diffs. It also monitors for regressions and spoof attempts, alerting when new unauthorized sources appear. This is not a full email security suite; it’s a focused DMARC rollout and maintenance tool for teams that are tired of spreadsheets, guesswork, and broken mail.
