Domain protection and security — FAQs

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.
