PatrOwl is a scalable, free and open-source solution for orchestrating Security Operations.
PatrowlManager is the Front-end application for managing the assets, reviewing risks on real-time, orchestrating the operations (scans, searches, API calls, ...), aggregating the results, relaying alerts on third parties (ex: Incident Response platform like TheHive, Splunk, ...) and providing the reports and dashboards. Operations are performed by the PatrowlEngines instances. Don't forget to install and deploy them ;)
