We built Postman, a secure government platform that enables all government agencies to send SMS messages through one unified "gov.sg" sender ID. This infrastructure ensures citizens receive important government communications quickly and reliably.
We created a public facing website where citizens can verify which agencies use the gov.sg sender ID, report suspicious messages, and access comprehensive FAQs. This hub serves as the central resource for citizens to understand and interact with the Postman Team.
We implemented multiple layers of security including IP whitelisting that ensures only authorized government systems can send gov.sg messages, secured connections from government systems to the telecommunication networks, and strict access controls that limit who can create and send government messages. These measures protect the integrity of the gov.sg channel against unauthorized use and impersonation.
Now I know when I see gov.sg, it is really from the government. Much clearer than before when there were so many different sender names.
