Is Halyard ISO 27001 certified?
Yes, certified since 2023 and re-audited each spring. The certificate and current statement of applicability are available on request.

"They have built something good in a corner that had not seen real work in years. Engineering peers keep bringing it up unprompted, which almost never happens with infrastructure."
