Domain protection and security — FAQs

Why is protecting my domain so important?

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. Customized DNS templates are also offered as a part of an optional add-on that will work with any domain.

Will the Domain Guard notify me when my domain is due to expire?

As long as you do not proactively cancel your domain (for which you will receive reminders from us in advance), we will auto-renew your contract. This way, you do not have to worry about your domain expiring unexpectedly.

Domain Guard features in detail

Protection from DNS hijacking

Hackers could redirect your domain to fraudulent or malicious websites, potentially allowing them to steal one of user's credit card details, or even claim legal ownership of your domain. Safeguard your name server settings and prevent changes to your DNS records. Domain Guard keeps your online presence secure and trustworthy.

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 and prevents hackers or unauthorized third parties from 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.

Authenticated proof of ownership

IONOS will provide you with a domain ownership document free of charge. You can use this document if you need to prove domain ownership to any third parties, or when dealing with various authorities, institutions or companies.
