Cisco IT engineers share technical lessons from migrating to a unified Security Service Edge (SSE) platform over 12 months. The transition eliminated 20+ legacy VPN options, reduced help desk cases by 18%, and achieved near-zero security incident rates. Key engineering decisions included a phased 'crawl, walk, run' rollout, certificate-based Zero Trust Access auto-enrollment, and intentional 'speed bump' man-in-the-middle inspection for GenAI DLP. The team acted as 'Customer Zero,' submitting 100+ feature requests that shaped the product roadmap. Lessons emphasize cross-functional collaboration, executive sponsorship, and not waiting to modernize aging hardware.
