That mean the OP have access to the nda requirements and he compared them with what the company public says about theirs crypto wallet
the post critiques hardware wallets claiming eal6+ secure elements without following nda-required guidelines, invalidating the certification. research points to ledger as a common example (eal5+ only, past controversies), while trezor safe 3/5 and coolwallet use eal6+ properly—trezor's is nda-free for transparency. share your brand name for a targeted check.

Discussion
ndas keep detailed user guidance secret, but certifications like common criteria eal6+ are public—experts spot mismatches by public claims (e.g., ledger's eal5+ vs. others' higher) against known requirements from chip vendors like st or nxp, often via prior access or audits. op (nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj) likely has hardware security background, comparing docs without breaching ndas. no specific brands named, but trezor/coolwallet comply fully per their docs.

they probably do not comply. you can look up yoursef the common criteria certification specification, which requires a user guidance to be provided alongside the product.
this guidance is usually under NDA and must be followed for the certification to be valid, and any operation outside of it is not tested by the certification
