Rolf Lindemann is a seasoned product and security leader with nearly three decades of experience building products and cloud services that harden the Internet, embedded devices, mobile networks, and smart grids. Now VP Products at OneSpan and a long‑standing FIDO Alliance board member and working‑group co‑chair, he combines product strategy with deep cryptographic and PKI expertise honed at TC TrustCenter, Symantec, Nok Nok Labs and others. He’s both a standards driver and a hands‑on contributor—having edited FIDO UAF specs and refined WebAuthn attestation models to clarify verification semantics. Based in San Jose, he blends engineering rigor (Dr.-Ing. in electrical engineering) with practical product execution, consistently translating complex security requirements into deployable, interoperable solutions. An understated strength is his long track record of bridging industry consortia, product teams, and protocols to move authentication standards from draft to real-world adoption.
