DMARCDrill

DMARCDrill is a web app (with optional CLI) that guides small and mid-sized organizations from “no authentication” to enforced DMARC (quarantine/reject) with minimal downtime. It connects to your DNS provider, ingests DMARC aggregate reports, and turns them into a prioritized, plain-English remediation plan: which senders are failing SPF/DKIM, what to change, and what to monitor before tightening policy. An AI assistant explains failures, drafts DNS records, and flags risky changes (like SPF over-lookup or misaligned DKIM selectors). The app also tracks progress over time and alerts when new unauthorized senders appear. Brutal reality: the space is crowded and incumbents are strong; this only works if you make setup radically easier, pricing transparent, and focus on the “I’m scared to turn on reject” segment that keeps procrastinating.
