In this demo, we present FENCE, a privacy-preserving, scalable solution for enterprise networks that continuously collects Internet access artifacts in real-time to help post-incident Internet forensics. We have built a data lakehouse to store these artifacts in a secure and compact query-friendly format. We implemented FENCE using open-source frameworks, deployed in a large enterprise with thousands of bring-your-own-devices (BYOD), and demonstrated that it works effectively in production environments. © 2023 IEEE.
