This project is about handling all the reports browsers (Content Security Policy, Network Error Logging etc.) and e-mail servers (DMARC, SMTP TLS etc.) can send nowadays.

To do that, this project contains a webserver, that will listen to incoming reports, validate them, filter them, structure them and log them to a file.
This log file can be read by your log monitoring tools like an ELK-stack or Grafana Loki.
With that, you can generate diagrams, configure alerts, you name it.
