Core capabilities
Built around the work your team actually performs.
MailDNS Guard helps organizations understand and improve email authentication posture while treating production DNS changes as controlled operations. Read-only discovery comes first, with validation, approval, snapshot, verification and rollback controls before any production change.
DNS record manager
Review A, AAAA, CNAME, MX, TXT, SRV and CAA records, validate changes and stage them through a controlled production workflow.
DMARC policy center
Build and validate DMARC policies, evaluate enforcement readiness, manage reporting addresses and avoid unsafe blind moves to reject.
SPF analyzer
Parse SPF recursively, count DNS lookups, identify risky nested includes and highlight configurations approaching the 10-lookup limit.
DKIM manager
Discover selectors, validate public keys, review signing health and check alignment requirements for active mail platforms.
Provider connections
Plan least-privilege connections to DNS and email providers with connection tests, zone discovery and explicit write capability controls.
Change control & rollback
Protect DNS changes with validation, before/after preview, administrator approval, snapshots, propagation verification and rollback.
Monitoring, reports & audit
Schedule posture checks, detect drift, produce management/audit reports and trace scans, approvals, provider actions and DNS updates.
