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.
