Composite VPN: A Modern Approach to Securing Federal Networks explains how permanent remote and hybrid work, BYOD adoption, and widespread mobile access have expanded attack surfaces for government agencies. The paper argues that traditional VPNs alone are insufficient and introduces Composite VPN as a zero trust approach that combines SSL VPN with next-generation firewall inspection. This model verifies user identity, device posture, and context before granting least-privilege access, while encrypting and inspecting all VPN traffic for malware, data leakage, and policy violations. By unifying Secure Mobile Access with firewall-based deep packet inspection, Composite VPN improves visibility, reduces lateral movement, and ensures consistent protection for users, devices, applications, and d
