Network design is being transformed faster than ever, as firms move to meet workers in new environments, apply simplified security on top of complex infrastructure and embrace cloud-native work. This article is part two of a three-part series, exploring the trends reshaping networking. In part one, we unpacked the rise of cloud-native networking, where service meshes, , and open standards are reshaping connectivity. However, agility alone is not enough. As threats multiply and data spreads across clouds, branches, and home offices, networks must be secure by design. This means building in principles, embracing frameworks like secure access service edge (SASE) and security service edge (SSE) , as well as preparing for a quantum-safe future.
