I'm not sure that your client is after exactly. But we do not have any ISO or other certification.
Dear WinSCP Forum,
I don't know if my issue fits in this branch.
A client (bank) asked for security documentation/certification (architecture, ISO etc.) for WinSCP, as they wanted to install a Secure tool, and not a "ransomware" etc.
Could you provide me the demanded documentation?
Best regards
