Cybersecurity and Zero-Trust Architectures for Mission-Critical Networks Market Size and Forecast

The global cybersecurity and zero-trust architectures for mission-critical networks market was valued at USD 21.8 billion in 2025 and is projected to reach USD 69.4 billion by 2032, growing at a CAGR of 18.3%. Growth is driven by escalating cyber threats to critical infrastructure, regulatory mandates, and the modernization of public safety, defense, and industrial communication networks.

Market Overview

Mission-critical networks support public safety, defense, utilities, transportation, and industrial operations where downtime or compromise can have severe consequences. Traditional perimeter-based cybersecurity models are inadequate against modern threats such as ransomware, insider attacks, and nation-state actors. Zero-trust architectures enforce continuous verification of users, devices, and applications regardless of network location. Cybersecurity solutions for mission-critical networks integrate identity-driven access control, encryption, micro-segmentation, and real-time monitoring. Adoption is accelerating as organizations converge IT, OT, and communications systems and deploy cloud, edge, and hybrid architectures. The market spans security platforms, zero-trust network access, monitoring tools, and managed services designed for high-availability environments.
