DNSSEC (DNS Security Extensions) is a security mechanism that is added to the domain name system. With DNSSEC, responses to a domain look-up are signed, so that it is possible to verify that they are coming from the correct source and have not been changed along the way. DNSSEC was implemented for Norwegian domain names in 2014.

The share of registrars of Norwegian domain names that offers DNSSEC has increased over the last years.

However, there are large differences in the degree of signing among the registrars. The majority of registrars have only signed a few percent of the domain names they manage, or do not offer such security of the customer's domain name. At the same time, there are some large registrars who offer the technology as part of their standard delivery, and who in sum ensure that more than half of all Norwegian domain names are signed.
