About this site.

The site

btplens.dev is the home of BTP Lens and a blog about application security, lifecycle risk and software supply chain hygiene on SAP BTP, for the people who run SAP extension apps. Posts name their sources. Numbers, dates and version numbers that could not be sourced are marked for review rather than smoothed over. Posts that mention BTP Lens say so, and they are written to be useful to someone who never installs it.

The author

Sebastiano Marchesini is a solution architect focused on SAP BTP, an SAP Champion, SAP PRESS author and SAP Learning instructor, and an IEEE Senior Member. He maintains BTP Lens, a free, open-source scanner for SAP BTP Cloud Foundry apps.
