Research from Palo Alto Networks reveals widespread security vulnerabilities in enterprise networks, with 26% of Linux and 8% of Windows systems running end-of-life operating systems. Analysis of 27 million devices across 1,800 enterprises found that 39% of IT devices lack endpoint security protections, 32.5% operate outside IT control, and 77% of networks have poor segmentation. Network edge devices like routers, IoT gear, and video conferencing systems pose significant risks due to unpatched vulnerabilities and default credentials. Security experts emphasize the need for continuous visibility, agentless monitoring, and risk-based patching, though replacing legacy systems remains challenging due to cost constraints and competing business priorities.
