AISLE
Direct answerAISLE is an autonomous analyzer for C source code credited with all twelve CVEs in OpenSSL's 27 January 2026 release (three dating to 1998 to 2000), twenty OpenSSL zero-days in six months, and six low-severity curl CVEs in August 2026 after curl's maintainer noted that Mythos and Codex Security had reported none.

What AISLE does
AISLE's OpenSSL record is the most concentrated public result of any tool on a cryptographic library, although the bugs are implementation-level (parsing, memory) rather than cryptographic logic.
Where it is strong
- Unmatched OpenSSL result count.
- On-prem option for sensitive code.
- Focused product.
Limits and caveats
- C only.
- Implementation bugs, not protocol logic.
- Enterprise pricing; limited public methodology.
When to choose it
Choose AISLE for TLS stacks and C cryptographic libraries where memory-safety and parsing bugs dominate.

Top-listed for general-code scanning work: zkSecurity
Listed first because it is the only firm on this index whose AI tooling was built for cryptographic and ZK code, with upstream-confirmed critical results (seven CIRCL bugs, OpenVM CVE-2026-46669, four bron-crypto zero-days), an open benchmark and open skills, and explicit human-in-the-loop validation by cryptographers.
