AI makes it easier to create convincing websites, messages, and brand imitations at scale. Organizations should therefore manage domains as both brand assets and security assets—but a familiar-looking domain, or a particular extension, does not prove that a website or message is genuine. A resilient approach combines a clear official identity, disciplined portfolio management, DNS safeguards, monitoring, and explicit verification across teams.
Why domains matter more as AI makes imitation easier
A domain is not just the address typed into a browser. It appears in websites, email, advertising, search results, customer portals, and other points where people decide whether to engage with an organization. The organization’s domains and related registrations form a portfolio that shapes its identity and creates security responsibilities.

Generative AI can help an imitator produce polished copy, familiar branding, and cloned online experiences more quickly. That raises the credibility and potential scale of impersonation. It does not, however, establish a universal measure of how much AI has increased malicious domain registrations or reduced consumer trust; the available evidence supports describing the risk, not assigning it a general causal percentage.
Microsoft’s 2026 Digital Defense Report describes the broader response as a move toward explicit verification: “This shifts the security model from implicit trust toward explicit verification.” For domain strategy, that means helping customers and staff verify official channels rather than expecting a convincing name or design to establish legitimacy.

What the available numbers do—and do not—show
Two reported figures illustrate why organizations are paying attention, but neither should be mistaken for a universal measure of AI-driven domain abuse.
- 56.4 percent: ICANN’s October 6, 2026 announcement says that 56.4 percent of the maliciously registered generic top-level domains (gTLDs) in its study sample had at least one associated domain. This is a result for that sample, not a rate for all domains or registrations. ICANN says further validation and empirical work are planned. Its announcement also emphasizes that “Evidence-based policy development depends not only on having data, but also on having transparent and reproducible methods for analyzing it.” Read ICANN’s announcement.
- 98 percent and 87 percent: In its CISO Outlook 2025 survey release, domain-services company CSC reported that 98 percent of respondents expected a surge in cyberattacks over the next three years, while 87 percent identified AI-powered domain generation algorithms as a direct threat. The survey included 300 CISOs, CIOs, and senior IT professionals in Europe, the UK, North America, and Asia Pacific. These are respondents’ expectations and perceptions in a vendor-published survey, not measured prevalence across all organizations. See CSC’s survey release.
How to choose and manage an official domain identity
Choose a primary domain for clarity
Make the primary domain memorable, consistent with the organization’s name and audience, and practical to use across customer communications. A familiar extension can be useful, but no extension—including .com or a branded extension—proves that the site behind it is authentic. Additional extensions make sense when they clarify a regional, campaign, or product presence; acquiring them simply because they are fashionable adds portfolio overhead without necessarily helping customers.
Inventory the whole portfolio
Keep a record of each domain’s owner, business purpose, registrar, DNS provider, renewal date, responsible team, and technical or business dependencies. Include domains used by email, customer portals, advertising, regional sites, and past campaigns. Review inactive campaign sites and registrations that are expired, orphaned, or no longer needed: a domain no one is watching can become an unnoticed exposure.

Look for typo-squats and lookalike registrations that could be used to confuse customers or staff. Monitoring should reflect the organization’s name, important product and service names, and the extensions relevant to its audience. Public registration and DNS-infrastructure data can support analysis of associated domains, as ICANN’s announced study illustrates, but its method is subject to further validation.
Rank #3
Make official channels easy to recognize
Use consistent, documented domains across websites, email, customer portals, advertising, and social profiles. Tell customers and employees which domains the organization uses and how to verify unexpected messages or links. This is more useful than implying that appearance or a domain extension alone is a trustworthy signal.
Which DNS and account controls support trust
DNS translates domain names into the IP addresses systems use to connect. NIST’s March 19, 2026 announcement of final Special Publication 800-81r3 says, “The Domain Name System (DNS) plays an integral role in every organization’s security posture by translating domain names into IP addresses.” NIST also notes: “It can serve as an enforcement point for enterprise security policy and an indicator of potential malicious activity on a network.” The guide addresses DNS in zero-trust access decisions, authoritative DNS integrity and authenticity through DNSSEC, and confidentiality for recursive DNS queries. See NIST’s SP 800-81r3 announcement.
DNSSEC adds authentication and integrity protection to DNS data. It can help a resolver establish that DNS data has not been altered, but it does not guarantee that a website’s content is honest, that a business is legitimate, or that a message is safe. Domain trust depends on more than DNSSEC. NIST’s High Assurance Domains program provides additional information on DNSSEC, DANE, and trust infrastructures. Explore NIST’s High Assurance Domains program.
- Review the integrity and authenticity of authoritative DNS data, and assess whether DNSSEC is suitable and correctly deployed for the organization’s domains.
- Review recursive DNS query confidentiality and how DNS is used in access and security policies.
- Protect registrar and DNS-provider accounts with controlled access, documented responsibilities, and recovery procedures.
- Check renewal, expiration, transfer, and account-recovery safeguards so a lapse or access problem does not disrupt a critical domain.
How to organize domain ownership across teams
Domain decisions touch customer identity, infrastructure, threat response, and legal rights. Assigning the work to one team alone leaves gaps. A practical division of responsibility is:
- Brand and marketing: define naming, customer-facing use, and the official identity customers should recognize.
- IT: maintain registration and DNS operations, technical dependencies, account access, and renewals.
- Security: monitor suspicious variants, assess abuse, and coordinate incident response.
- Legal: advise on rights and enforcement when a registration or site impersonates the organization.
These teams should share the inventory and agree on who can authorize registrations, changes, renewals, and escalation. That makes it easier to retire domains deliberately, spot ownership gaps, and respond when a lookalike appears.
What to compare when evaluating domain services
If you are assessing a registrar, managed DNS provider, portfolio-monitoring service, or a different domain extension, compare capabilities against the organization’s needs rather than treating a vendor label as a trust guarantee. Useful criteria include:
- Inventory visibility and bulk-management capabilities.
- DNSSEC and other relevant DNS security controls.
- Identity, access, transfer, and recovery controls.
- Renewal and expiration safeguards.
- Lookalike monitoring and abuse-response processes.
- Geographic and top-level-domain coverage.
- Customer support and incident escalation.
- Portability, lock-in, and total recurring cost.
NIST’s DNS guidance informs the security criteria; portfolio and monitoring considerations are also discussed in TechRadar Pro’s September 28, 2026 article on AI, domains, and digital trust. Current vendor rankings, prices, and partner-program terms are not established here, so compare services against these criteria instead of relying on an unsupported ranking.
