In the rapidly evolving digital economy, cybersecurity has emerged as a fundamental pillar for sustaining economic performance, safeguarding critical infrastructure, and fostering investor confidence. As economies digitize, the risk of cyber threats intensifies, prompting both public and private entities to allocate significant resources toward cybersecurity investments. However, the financial implications of these investments raise critical questions about their actual economic benefits and sustainability. This paper explores the intricate relationship between cybersecurity investments and economic performance, with a focus on evaluating the cost-benefit trade-offs in various sectors. It emphasizes how effective cybersecurity strategies can minimize financial losses from cyberattacks, enhance data protection, and strengthen trust in digital transactions thereby boosting productivity and economic growth. At the same time, it critically examines concerns over the high upfront costs, recurrent expenditures, and the opportunity costs of diverting resources from other developmental priorities. The study also addresses how poorly managed cybersecurity spending can lead to inefficiencies, emphasizing the need for balanced and evidence-driven investment decisions. By assessing economic indicators, industry trends, and real-world cases, the paper highlights how strategic cybersecurity planning can serve not only as a defensive mechanism but also as a catalyst for innovation and long-term economic resilience in an increasingly interconnected world.
