How to Keep Your Business Domain Name Secure

Why Domain Security Matters

Control of a business domain can affect the website, email, customer trust and access to other online accounts.

If an attacker gains control, they may redirect visitors, intercept messages, impersonate the company or disrupt operations.

Domain security should therefore be treated as a core business responsibility.

Use a Reputable Registrar

Choose a registrar with strong account security, clear support and reliable renewal processes. Zycon is a Nominet-approved registrar; more background is available on the About Zycon page.

Check whether it offers two-factor authentication, transfer locks, account alerts and additional protection for valuable domains.

Low price is not the only consideration.

Use a Unique Password

The registrar password should be long, unique and stored in a reputable password manager.

Do not reuse a password from email, social media or another service.

A breach elsewhere should not give an attacker access to the domain.

Enable Two-Factor Authentication

Two-factor authentication adds a second requirement beyond the password.

An authenticator app or hardware security key is generally preferable to relying solely on text messages where stronger options exist.

Store recovery codes securely and test the recovery process.

Protect the Account Email

The email address used for domain administration is itself a critical security asset.

Secure it with a unique password and two-factor authentication. Do not use an address that will stop working if the domain expires.

Review account-recovery options and remove outdated telephone numbers or addresses.

Apply Transfer Locks

Many registrars offer a lock that helps prevent an unauthorised transfer.

Enable the available lock unless a legitimate transfer is in progress.

For high-value domains, ask about registry-level protection or manual approval controls.

Control Who Has Access

Give administrator access only to people who genuinely need it.

Use separate user accounts and permissions where the registrar supports them rather than sharing one password.

Remove access promptly when staff, agencies or contractors leave.

Keep Ownership Records Accurate

Ensure the registrant information correctly reflects the person or organisation that should control the domain.

Keep invoices, agreements and account records.

Unclear ownership can become a serious problem during a dispute, company sale or supplier breakdown.

Prevent Accidental Expiry

Enable automatic renewal and keep the payment method current.

Maintain independent calendar reminders and renew critical domains early. Our guide to what happens when a domain name expires explains the operational and security risks of missed renewal.

Check that renewal messages go to an actively monitored external address.

Monitor DNS Changes

Unexpected DNS or nameserver changes can redirect the website and email. Understanding the relationship between domains, DNS, websites and hosting makes suspicious changes easier to recognise.

Use registrar alerts or external monitoring to detect changes.

Investigate any notification immediately through a trusted route.

Secure the DNS Provider

If DNS is managed separately from the registrar, protect that account to the same standard.

Use two-factor authentication, limited access and change alerts.

Document which provider manages DNS and how emergency access works.

Watch for Phishing

Attackers may imitate registrar renewal notices, transfer emails or security alerts.

Do not follow unexpected links. Open the registrar site directly or use a saved bookmark.

Verify changes to payment instructions and support contacts independently.

Protect Against Social Engineering

An attacker may contact support while pretending to be the registrant.

Use registrar security questions or account notes carefully, and avoid publishing information that makes impersonation easier.

Ask the registrar about enhanced verification for valuable assets.

Create an Incident Plan

Record the registrar’s emergency contact process, account identifiers, ownership evidence and authorised decision-makers.

If control is lost, contact the registrar and registry immediately, preserve evidence and secure related email accounts. If a registrar move becomes necessary, follow the steps in How to Transfer a .co.uk or .uk Domain Name.

A prepared response can reduce downtime and damage.

Review Security Regularly

Check the domain account at least periodically rather than only at renewal time.

Review users, recovery details, locks, nameservers, payment methods and expiry dates.

Update the records after staffing, agency or company changes.

Frequently Asked Questions

Can a domain name be stolen?

Yes, through account compromise, fraud or unauthorised transfer, although strong controls reduce the risk.

Is WHOIS privacy enough?

No. Privacy may reduce public contact data but does not replace account security.

Should my web designer hold the domain?

They may manage it, but the business should retain clear ownership and reliable access.

What is registry lock?

It is an enhanced protection that can require additional verification before important changes.

Summary

Secure the registrar account with a unique password, two-factor authentication, transfer locks and tightly controlled access.

Protect renewal, ownership and DNS records, and monitor for unexpected changes. Zycon customers can also consult the frequently asked questions for renewal and registrar-transfer information.

Document an emergency process so the business can act quickly if a problem occurs.
