Censys ASM review: first-party internet scan evidence, seeded by you

THE SHORT ANSWER

Censys ASM ranks 9 of 10 at 5.15 out of 10. Its first-party scanning across all 65K ports and its long integration list are real strengths. Discovery grows from seeds you supply, proof stops at reachability with EPSS and KEV context, and no compensating control is documented.
