#Quantum-Resistant Secure Network Overlay Market Demand Drivers Opening New Revenue Streams#_x000D_
The expansion of the quantum resistant secure network overlay market is projected to be driven by the increasing magnitude of cybersecurity threats. Such threats are characterized as attempts or attacks designed to jeopardize the confidentiality, integrity, or availability of digital systems or data. The proliferation of these threats arises from the continually evolving tactics of malicious actors and the expanding attack surfaces present in interconnected environments. The quantum resistant secure network overlay market contributes to addressing this driver by providing a protective layer that utilizes post quantum cryptography to secure communications across vulnerable networks. For example, in October 2024, figures from Check Point Software Technologies, an Israel-based cybersecurity vendor, indicated that organizations experienced an average of 1,876 cyberattacks each week, marking a 75% rise from the equivalent period in 2023. Thus, the escalating cybersecurity threats are propelling the growth of the quantum resistant secure network overlay market._x000D_
