There appears to be some confusion surrounding your question, since as of the date of the answer, there is no top-level domain (TLD) called .SECURE recognized in the database of the Internet Assigned Numbers Authority (IANA), which is the official body that oversees global IP address allocation, autonomous system number allocation, root zone management in Domain Name System (DNS), media types, and other Internet protocol assignments.
According to IANA’s Root Zone Database, which is the authoritative record of the operators of various top-level domains, neither .SECURE, nor something similar, is listed. This database lists all TLDs, including generic top-level domains (gTLDs), country-specific code top-level domains (ccTLDs), and internationalized top-level domains (IDNs). The absence of .SECURE from these listings means this domain extension does not exist in the current configuration of the Internet’s domain name system.
The concept of a .SECURE domain name has been proposed in the past. Amazon, for instance, submitted an application for the .SECURE gTLD back in 2012 as part of the Internet Corporation for Assigned Names and Numbers (ICANN) program to expand the number of generic TLDs. According to ICANN’s application for the .SECURE domain, Amazon planned to operate it “as a closed domain,” hosting networked services and resources in a secure and trustworthy environment.
This application, however, encountered complications during ICANN’s review process. The body’s Government Advisory Committee issued advice against the application in 2013, voicing concerns over security risks and calling for a more transparent operation.
Amazon challenged this advice and, after years of legal and procedural wrangling, ultimately chose to withdraw the .SECURE application in 2017. Therefore, as of now, there is no .SECURE TLD.
As a result of these circumstances, it may not be possible to provide examples of .SECURE domain usage in action or to cite authoritative sources discussing a domain that does not exist. This could change in the future, as TLDs are continually being proposed and implemented.
Thus, it’s important to verify from a reliable source such as IANA or ICANN for up-to-date information on TLDs.
