Anne-Marie Eklund Löwinder was instrumental in developing systems that ensure internet users are accessing secure websites. She played a significant role in the development of Domain Name System Security Extensions (DNSSEC), and has since been an internet advocate, promoting internet safety and security around the world.

Eklund Löwinder is currently one of seven people in the world who control the DNSSEC key generation for the internet root zone, which essentially ensures the security of the internet, according to the Guardian. She carries two copies of the physical key, which when put together with the other six, control the world wide web as we know it.
