Censys Attack Surface Management

Censys is an internet intelligence company that became a standalone company in 2017, building on research that began with the ZMap scanner in 2013. It helps security teams find and monitor every internet-facing asset of their organization.

Censys Attack Surface Management scans all 65,535 ports continuously, keeps history, detects dangling DNS records, self-signed certificates and services on nonstandard ports, ranks risks by severity and pushes findings into ticketing, SIEM and vulnerability tools. A Censys Assistant answers questions in plain language and generates reports. Named customers include T-Mobile, Walmart and Bank of America.

• Full-port scanning: continuous scanning of all 65,535 ports with preserved history.
• Change alerts: notifications on new hosts, ports, certificates and services.
• Risk ranking: findings sorted by severity, category and affected asset.
• Rapid response: new exploitation flagged by Censys ARC is checked against customer assets.
• Censys Assistant: natural-language questions and on-demand executive reports.
• Cloud context: metadata from AWS, Azure, GCP and Wiz connectors.

A Vietnamese bank security team can inventory forgotten subdomains and exposed services across branches and fintech partners. An e-commerce group can detect dangling DNS records before takeover. A SOC can check new exploited vulnerabilities against its internet-facing hosts.

Gives a continuously updated inventory of internet-facing assets including unknown ones. Ranks risks by severity, category and asset to focus remediation. Sends findings to existing ticketing and SIEM workflows. The vendor claims exposures surface up to 6 times faster than other ASM tools.

Organizations run growing numbers of cloud and third-party assets, so asset inventory and exposure monitoring from an outside view are becoming a baseline control. Vendors now add AI assistants to speed up triage. Vietnamese enterprises expanding cloud and partner integrations face the same visibility gap.
