Summary
👤
Senior🎓
Top SchoolVjaceslavs Klimovs is a cybersecurity leader and advisor with two decades of experience designing and operationalizing enterprise and hyperscale security architectures. He has served as a CISO-level architect and senior engineer at Google, Snap, CoreWeave, and startups, building and scaling security organizations to 50–80+ engineers and delivering industry-first programs for GPU-native AI infrastructure and large-scale identity and access systems. His work spans Zero Trust, PKI, machine identity, hardware-rooted trust, and authorization modernization, with measurable outcomes such as dramatic reductions in credential sprawl and access overprovisioning. Comfortable moving from executive strategy to hands-on code and tooling, he contributed upstream changes to the well-known capirca ACL generator and has a track record of converting complex risk decisions into pragmatic, auditable roadmaps. Based in the Bay Area, he pairs a master’s in information security with deep product and infrastructure instincts to align security controls to business goals. Notably, he has driven large-scale migrations—like company-wide ABAC/RBAC and bearer-token elimination—while keeping operational costs and engineering friction low.
