Cognizant Technology Solutions

Cognizant operates at a scale where the threat surface isn't theoretical - it's the converged attack plane of banking systems, healthcare data pipelines, and manufacturing OT networks. Over 350,000 associates work across these verticals, which means security teams are defending environments where a breach in one domain has direct, measurable consequences in another: a compromised health record can expose financial data; a pivot through an industrial control system can disrupt supply chains. The company's security work sits at the intersection of modernizing legacy infrastructure and deploying cloud-native architectures, a dual mandate that creates both complexity and opportunity. As a Nasdaq-100 and S&P 500 company, Cognizant's security posture is under constant scrutiny from regulators, clients, and adversaries alike. The engineering challenge is real: you're not just building defenses for internal systems - you're helping clients across highly regulated industries (banking, healthcare, manufacturing) harden their own environments while simultaneously transforming them. That means security tooling and strategy have to work across heterogeneous estates, from on-prem mainframes to multi-cloud deployments, with zero tolerance for the kind of gap that turns into a headline. The work culture emphasizes diverse experiences and backgrounds, which in a security context translates to varied perspectives on threat modeling and incident response. Teams are structured to engineer solutions across the full lifecycle - from architecture and hardening to detection, response, and recovery - within environments where the stakes are never abstract. If you want to operate at scale against real-world threat models across critical infrastructure, this is the kind of shop where that work happens.
