DKIM usually breaks during provider change, key rotation or forgotten selector cleanup, not during a calm maintenance window.
AIDE helps teams watch selector health and signing continuity across managed domains so mail trust does not depend on memory or one-off audits.

What teams need from DKIM monitoring
Most buyers are trying to protect ongoing signing trust, not just inspect one selector by hand.
Did migration leave selectors behind
Legacy providers often leave stale selectors while the new sender configuration is incomplete.
Will signing still align with policy
DKIM matters because it supports DMARC enforcement and domain trust downstream.
Which domains are drifting
Portfolio teams need to know where selectors are weak or inconsistent without checking each domain manually.
What AIDE checks around DKIM
DKIM monitoring is part of an ongoing trust model, not a static configuration checklist.
Selector presence
Keep track of whether the selectors required by current sending systems are actually published.
Signing continuity
Notice when provider or key changes threaten consistent DKIM validation.
Portfolio drift
Review how DKIM posture varies across many managed domains at once.
DMARC alignment context
Interpret DKIM inside the policy framework that determines whether failures matter.
How this fits into the platform
DKIM monitoring is much more useful when the platform can also tell you what changed in DNS and what policy now depends on it.
AIDE connects selector health to broader email security posture so teams can triage risk instead of just collecting DNS fragments.

Email security monitoring
Review DKIM alongside SPF, DMARC and transport policies instead of treating mail trust as separate silos.
DMARC monitoring
DMARC enforcement determines whether DKIM success or failure materially changes domain trust.
DNS monitoring
Selector changes are DNS events and should be tracked with the same rigor as other critical TXT records.
Monitor DKIM the way portfolio teams actually need it monitored.
AIDE helps operators keep selector and signing posture connected to the rest of the domain infrastructure model.
