Domain Guard features in detail

Protection from DNS hijacking

Hackers could redirect your domain to fraudulent or malicious websites, potentially allowing them to collect the credit card details of your users or to claim legal ownership of your domain. Domain Guard counters these attacks and protects your DNS records.
Icon: Two-factor authentication

Two-factor authentication

Any changes to your domain and its records must go through an additional verification step where a security link is sent to your email address. This adds an extra layer of security, ensuring that hackers and other third parties stand no chance of stealing your domain.

Improved security with DNSSEC

Your DNS records store information on how your domain is connected to an IP address. Domain Guard protects your DNS records through DNSSEC, leaving hackers unable to manipulate these important details or reroute them to fake destinations.

Premium Anycast

Reduce your website's loading time, no matter where your visitors are located. Unlike standard name servers, Premium Anycast has server locations on all continents so your visitors always benefit from a fast name resolution.

DNS Backup

Manage custom templates for groups of DNS records to configure DNS zones quickly and easily. Create backups of your entire DNS zone and restore it at any time, reducing costly downtime.

Secondary/Slave DNS

The operator of an authoritative name server can use IONOS as a secondary DNS provider. This increases the availability and performance of name resolution.

Domain protection and security

FAQ – Frequently asked questions

Protecting your domain name is critical to maintaining a healthy online presence. One way of doing this is with private domain registration. This hides your personal contact data from the public, effectively masking your registration details with the name of your web hosting provider. It's only available with certain domains.

Having authenticated proof of your domain ownership and preventing third-party access to your personal domain data can also help protect your domain name.

IONOS offers a wide range of domain security and protection services. With IONOS domain security products like Domain Guard and DNS Pro, you can protect your domain from DDoS attacks, safeguard against DNS hijacking and spoofing via DNSSEC, ensure faster, reliable, and secure DNS resolution, and choose Premium Anycast or secondary DNS with DNS backup and restore. Customised DNS templates are also offered as a part of an optional add-on that will work with any domain.

As long as you don't cancel your domain, we will auto-renew your contract. This way, you don't have to worry about your domain expiring unexpectedly.

Private domain registration makes sure that your Whois information is not visible to third parties. Domain Guard, however, protects you against hackers trying to access and alter your DNS records.
