Email and SMS are not 100% secure. We recommend that you don’t put any sensitive information in the email or SMS content. Some of our users generate a recipient-specific unique link that opens up to a locked page. We have completed our VAPT on June 15th, 2020, and fixed our vulnerabilities.
Postman.gov.sg is only available on the internet at the moment.
When in doubt, you should follow IM8’s guidelines on data classification. We use cloud infrastructure so we are able to handle up to restricted data.
