OutSystems Platform has full support for HTTPS (SSL/TLS), allowing teams to secure application end-points. The platform supports all:
SOAP web services
This ensures the data an organizations' customers sends can't be eavesdropped or tampered with. For enhanced security, OutSystems Platform also supports SSL with client certificates.
It's simple to enable HTTPS for your pages and services, by checking a property on the visual IDE when developing the application.
