TL;DR: Weak domain management can lead to outages, loss of control, and DNS-based abuse, while large organisations may own more than 3,000 domains and nearly one-third manage over 10,000, according to DigiCert and a 2025 GCD survey. The governance lesson is clear: domains behave like identity assets and need central ownership, access control, and lifecycle discipline.
Editorial analysis by NHI Mgmt Group, based on content published by DigiCert: “The Importance of Domain Management”.
By the numbers:
- More than half (56%) of respondents from large companies reported owning more than 3,000 domains, according to a 2025 GCD survey cited by DigiCert.
- Nearly one-third (29%) of respondents from large companies reported managing over 10,000 domains, according to a 2025 GCD survey cited by DigiCert.
Key questions
Q: What breaks when domain management is not centrally governed?
A: When domain management is fragmented, the failure is usually not one thing but several at once: renewals lapse, DNS changes drift, and account ownership becomes unclear.
Q: Why do DNS misconfigurations create both availability and security risk?
A: DNS misconfigurations affect where users and services are directed, so a single bad record can cause outage, redirect traffic, or expose dependencies.
Q: How do security teams know if parked domain governance is working?
A: Parked domain governance is working when every registered domain has an owner, purpose, renewal date, and configuration baseline, and when unused domains are either redirected or retired.
Practitioner guidance
- Centralize domain ownership Maintain a single authoritative inventory of every domain, registrar account, renewal date, DNS zone, and contact owner.
- Lock down registrar and DNS changes Require MFA, domain locking, and role-based access controls for every registrar and DNS console.
- Automate renewal monitoring Enable auto-renewal, keep payment details current, and add early alerts so a payment failure does not become a domain lapse.
Bottom line: Domains behave like security assets because control over registration and DNS can affect availability, trust, and service integrity at the same time.

Domain management has crossed into identity governance territory. The control points described in the article are not merely technical housekeeping. Registrar ownership, DNS change authority, and renewal responsibility all define who can assert control over a business-critical asset, which is the same governance question IAM answers for accounts and entitlements. For practitioners, that means domain portfolios belong in the same ownership and review discipline as privileged access.
A few things that frame the scale:
- An unplanned outage in a cloud environment costs an average of $9,000 per minute, per the Uptime Institute’s 2023 Global Data Center Survey.
A question worth separating out:
Q: What is the difference between registrar control and DNS control?
A: Registrar control governs who owns the domain, can renew it, and can transfer it. DNS control governs how that domain resolves into services such as websites, mail, and verification records. Both are security-sensitive, but registrar compromise threatens ownership while DNS compromise threatens service integrity and traffic routing.
