In an era where digital threats are ever-evolving, both individuals and organizations—especially in civil society and advocacy—face increasing risks to their safety, privacy, and effectiveness. This practical, step-by-step course empowers activists, NGO staff, community leaders, and anyone working in civic engagement to defend themselves and their organizations online. Participants will learn to recognize threats, implement core digital security practices, equip their teams, secure communications, and respond to incidents. With a focus on real-world scenarios and tools relevant for resource-limited and high-risk contexts (such as West Africa), this course guides participants to build resilient digital habits and create a lasting security culture.
