At Paddy Power Betfair (Blip.pt), throughout the years, we have developed a tool to help us have an inventory of all internal assets, from servers to DNS records to endpoint devices, but to also integrate other tools in it, like open-source scanners to help us detect vulnerabilities, understand our exposure, weaknesses, and priorities, as well as leverage built-in notifications, a slack bot, and much more.
These slides were used in the OWASP Lisboa Chapter #2 meetup by me, to present and talk about the project.
