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. Domain Guard counters these attacks and protects your DNS records.
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.
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.
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.

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.
