"Censys was faster in terms of coverage of the internet at the time. Every 3 days there’s a light weight scan, and then there’s a more in depth scan over a longer period. Also companies often run things on non-standard ports, so scanning a large number of ports are important, and Censys offered the best port coverage."
“The powerful search functionality and extensive historical data made Censys great to use for attribution. Censys is used in almost every investigation we do.”
