DNS ownership gaps and certificate delays: what IAM teams miss

TL;DR: DNS pre-validation lets organisations prove domain ownership ahead of time so certificate authorities can issue or renew TLS certificates without waiting on manual DNS changes, reducing delays caused by siloed ownership and ticket queues, according to DigiCert. The real issue is not validation mechanics but governance: certificate lifecycles fail when DNS access, ownership, and renewal authority are not aligned.

NHIMG editorial — based on content published by DigiCert: Pre-Validated DNS: Eliminate Certificate Delays from Ownership Gaps

By the numbers:

• 69% of organisations now have more machine identities than human ones.
• 66% say their current tooling is not adequate to manage the scale of machine identities they now have.
• Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.

Questions worth separating out

Q: How should security teams implement DNS pre-validation for certificate renewals?

A: They should pre-create the validation records, confirm who can change the relevant DNS zone, and test the renewal workflow before certificates near expiry.

Q: Why do DNS ownership gaps cause certificate delays in mature environments?

A: Because certificate issuance depends on proving domain control, and that proof usually requires a DNS change by the team that owns the zone.

Q: What breaks when validation records are left unmanaged after certificate automation?

A: Stale validation records can create lingering trust paths, while dangling DNS entries may expose takeover opportunities or confuse renewal workflows.

Practitioner guidance

• Map DNS authority to certificate ownership Document which team, system, or third party can create the validation record for every domain before renewal dates approach.
• Automate DCV with controlled API credentials Use ACME clients only where the DNS API credentials are stored in governed secret management, scoped to the minimum record set, and monitored for change activity.
• Keep persistent validation records under lifecycle review Review reusable TXT or CNAME validation records on the same cadence as certificate inventory and zone hygiene.
