The FBI has launched Operation Winter SHIELD—Securing Homeland Infrastructure by Enhancing Layered Defense—to equip organizations with effective strategies for addressing the growing threat of ransomware and other cybersecurity risks. These threats endanger not only corporate data but also critical sectors such as healthcare, energy, and manufacturing.

Operation Winter SHIELD offers a practical, actionable framework designed to reduce the likelihood of cyber intrusions and limit their impact when they occur. A core principle of the initiative is the emphasis on strong public-private partnerships, leveraging industry collaboration as a powerful force multiplier in strengthening the nation's cyber defense posture.

Operation Winter SHIELD (Securing Homeland Infrastructure by Enhancing Layered Defense) distills the FBI's 10 most impactful actions organizations can take to improve resilience against cyber intrusions. These recommendations were developed with domestic and international partners and draw on recent investigations to reflect adversary behavior and defensive gaps.

This campaign ties directly to the National Cyber Strategy and the FBI Cyber Strategy and positions industry not as passive victims or recipients of intelligence but as critical allies alongside the FBI and our partners in detecting, confronting, and dismantling cyber threats.

Winter SHIELD provides industry with a practical roadmap to better secure information technology (IT) and operational technology (OT) environments, hardening the nation's digital infrastructure and reducing the attack surface.

Our goal is simple: to move the needle on resilience across industry by helping organizations understand where adversaries are focused and what concrete steps they can take now (and build toward in the future) to make exploitation harder.
