Censys ASM: CAASM and asset inventory facts (2026)

SHORT ANSWER

Censys ASM looks from the outside in, with first-party scanning of all 65K ports, and names integrations from ServiceNow CMDB to Microsoft Sentinel, Tenable VM and Axonius. A free platform account lets you see its data before a sales call. It covers internet-facing assets only, discovery starts from seeds you supply, and ASM pricing goes through sales.
