Host dynamic SPF records at the edge, delegate DMARC governance with CNAME records, and run real-time mail diagnostics across your domain portfolio.
Delegate complex messaging infrastructure to Cloudflare edge proxies and automated Google Cloud backend workflows.
Dynamic tree flattening eliminates the RFC 7208 10-lookup limit with synchronous edge caching.
Automated 2048-bit key management and selector rotation without manual BIND updates.
Aggregate XML RUA threat telemetry directly into BigQuery analytics to reach p=reject fast.
Passive reconnaissance flags decommissioned cloud host pointers before subdomains get hijacked.
Automate TLS-reporting, VMC verification, and domain perimeter hardening across all enterprise zones.
Choose an instant domain fix or unlock automated continuous protection.
Immediate SPF flattening and full perimeter security audit for a single domain.
Continuous automated DNS monitoring, dual-approval API mutation access, and BigQuery telemetry storage.
We query and expand all dynamic includes into direct IPv4 and IPv6 blocks, serving flat TXT records at the edge so your domain never breaches the RFC 7208 10-lookup threshold.
When you decommission a cloud host (e.g., AWS S3, GitHub Pages, Heroku) without removing the CNAME record, an attacker can register that same cloud bucket name and hijack your subdomain. Sledgeheader continuously audits your CNAME records to flag dangling targets immediately.
