Censys Introduces Censys Search 2.0: A Brand New Scanning Engine that Finds Tremendously More Services on Risky Non-Standard Ports

Censys' new scan engine also includes several significant enhancements, such as daily refresh of known services, automatic protocol detection, and various global vantage points, which assist security teams in conducting improved threat hunting, asset discovery, and OSINT for Red and Blue Teams.

FREMONT, CA: Censys has unveiled a new version of its public search engine, which continuously indexes Internet services on over 2,500 ports, providing 177x times more coverage than in its original 2015 service. Censys' new scan engine also includes several significant enhancements, such as daily refresh of known services, automatic protocol detection, and various global vantage points, which assist security teams in conducting improved threat hunting, asset discovery, and OSINT for Red and Blue Teams.

"Censys Co-founder, Zakir Durumeric, stated, "When we originally launched Censys in 2015, we scanned 14 popular ports. Since then, security researchers have shown that services are spread across a tremendous number of ports and that services are changing nearly constantly. We've designed a new scan engine that continuously scans an extended set of ports to help defenders and researchers more comprehensively find security problems."

Censys monitors the top 100 ports on a daily basis. Censys' new engine searches the top 100 ports daily and the top 2,500 ports every ten days across all public IPv4 hosts, discovering roughly four times the number of services as the previous platform and 85 percent more services than our nearest competitor. Censys additionally refreshes known services on a regular basis to ensure that users receive up-to-date service information despite ongoing Internet churn.
