Expleo is a global engineering, technology, and consulting services firm that embeds with clients in sectors where the threat surface is both physical and digital: aerospace, defence, automotive, banking and financial services, insurance, energy and utilities, life sciences, marine, rail transportation, space, and retail/logistics. The company's scope runs end-to-end across integrated engineering, quality services, and management consulting - meaning security practitioners here aren't bolted on at the perimeter but woven into systems design, validation, and operational workflows across the full lifecycle.
Founded in 1970, Expleo has decades of institutional knowledge in regulated, high-consequence environments. That matters for cybersecurity roles because the work sits at the intersection of legacy industrial control systems, modern cloud-native architectures, and compliance frameworks that don't tolerate hand-waving. You're dealing with adversaries who target operational technology, supply chains, and financial infrastructure - not just endpoints.
The consulting arm means teams operate in advisory and execution capacities: threat modeling embedded in engineering processes, quality assurance that includes security validation, and management consulting that extends to governance and risk. The global footprint provides access to cross-sector projects, but the specific tooling, methodologies, and team structures aren't publicly detailed.
