NAUT tracks 25 crypto security companies whose own NAUT row names a crypto or Web3 security product, read on 2 November 2026: 7 that audit code, 6 that monitor live transactions, 4 that run incident response or threat intelligence, 1 bug bounty protocol and 7 broader security platforms. NAUT's data shows 19 of the 25 name at least 1 founder with their own NAUT page, and the 25 firms carry 68 person rows between them.
How this list was built: on 2 November 2026 NAUT read the 26 company and service rows that surface under its security and audit service tags, kept the 25 whose own description names a crypto or Web3 security product, and left out Qingteng Cloud Security, a host and workload security vendor whose description names no crypto product. Only 1 of the 26 rows carries NAUT's own security service tag; 22 carry audit, 2 compliance and 1 research, so a reader searching the tag alone would miss most of this list. The product groups below are NAUT's reading of each row's own description, never a NAUT tag. The People column is the live person rows NAUT's own record holds for each firm on 2 November 2026, with archived duplicate rows excluded; 67 of the 68 rows have their own NAUT page. NAUT also holds a second, archived row for Blowfish co-founder and CTO Kim Persson and for fuzzland_ co-founder and CTO Chaofan Shou, and those 5 archived duplicates sit outside the 68. A firm's public NAUT page can show fewer than its record holds, so treat the People column as NAUT's record, not a headcount.

20 of the 25 carry an X follower count on NAUT's record. The 5 service rows without 1 are the firms NAUT holds as service providers, so a BD team ranking crypto security providers by audience should treat those 5 as unmeasured here.
