From "my very own world", I worked on an earlier version of this project

for three years (not all the time, though), but the latest version to scan local disk drives is a complete rewrite by two of our other developers, all written in Python and Django and some frontend stuff:

The version I worked on was a "web scanner" service to scan municipal web sites to discover if they accidentally were leaking private information. The "data scanner" can't be a service but must be installed locally because it scans data that should never leave the premises of the given organizations.

In all cases, it's nice that it's possible to do that kind of specialized application in a way that's completely open to reuse:

"The software can easily be set up for testing and pilots. Next to sharing all of the source code as open source, Magenta is making the tool available in an Ubuntu container, ready for use."
