tlsscout is a django implementation of the ssllabs website scanner API. You can run tlsscout on your own server to check your websites periodically, with alerting when something changes.
See requirements.txt for a list of packages used by tlsscout. You will also need something to serve the application. I prefer uwsgi behind an nginx server. YMMV.
Create a database, anything supported by Django is fine.
Copy tlsscout_settings.py.dist to tlsscout_settings.py and change:
Run "manage.py migrate" to populate the database, and then update the 'name' and 'domain' columns in the 'django_site' table to match your tlsscout instance.
By default ALLOW_ANONYMOUS_VIEWING is True which means that the information collected by the tlsscout instance is public without logging in. Set to false to require login to see stuff.
By default ENABLE_SIGNUP is true which means new accounts can be created. Change to False to prevent new signups.
