As an additional security measure, SMPP over SSL/TLS is an option. You need to use our public certificate and connect towards 8008 port instead.
In order to use our public certificate, you would need to:
- Retrieve the certificate from https://www.nexmo.com/ (the certificate is a wildcard for *.nexmo.com)
- Export it in the format you prefer
- Import it into your application
