Censys implemented a lightweight protocol scanning framework to rapidly expand its internet service fingerprinting, increasing supported protocols from ~40 to 100 by enabling configuration-driven probes (no code) and using a unified banner_grab field. The report outlines prioritization criteria, examples of new protocols added (e.g., RTSP, PORTMAP, NETBIOS, Kerberos, PJL), and provides a snapshot table of service counts across the internet as of 2021-08-16.
