The US government is taking robust steps for serving the .gov domains over encrypted
connections. The government held its DotGov Program recently and planned to introduce to
preload an entire top-level domain (TLD) for ensuring enhanced security.
The .gov is the representative TLD for government organizations in the US, however many of
the domains have not implemented the secure HTTPS protocol.
Concerted efforts from major technology companies have resulted in the adoption of HTTPS
over the years. Thus, the administration is acting on protecting information and visitors
from potential attacks.
