Every CIO faces the same question right now: how do you secure an AI-powered, distributed workforce without adding more complexity to an already overloaded team? Cisco IT faced that question\u2014and built the answer. In 12 months, Cisco IT reduced help desk cases by 18%, cut security incident rates to near zero, and eliminated 20+ legacy VPN options\u2014all while securing AI adoption at scale. Here\u2019s how they did it, according to the engineers.<\/em><\/p>\n

In previous blogs, we explored the <\/span>strategic imperative behind Cisco\u2019s shift to a Zero Trust architecture<\/span> and examined the <\/span>organizational blueprint that guided our phased migration to a unified Security Service Edge (SSE) platform<\/span>. While those perspectives outlined the \u2018why\u2019 and the \u2018how\u2019 of our high-level transformation, we\u2019re pulling back the curtain on the engineering reality. As the lead engineers behind this transition, we\u2019ve spent the last year moving from a fragmented, hardware-heavy model to a unified, cloud-native SSE fabric. Here, we share the technical lessons learned from the front lines, the challenges of dismantling legacy infrastructure, and how we re-engineered our security stack to support a modern, AI-ready workforce.<\/span>\u00a0<\/span><\/p>\n

Managing tens of thousands of devices across a global workforce with aging, end-of-life infrastructure wasn\u2019t just an operational grind\u2014it was a technical bottleneck that created significant security debt. We were spending more time \u2018stitching\u2019 disparate hardware components together than we were on strategic security posture. We needed to move away from the \u2018box-by-box\u2019 management model toward a unified, software-defined fabric.<\/span>\u00a0<\/span><\/p>\n

We knew we had to shift toward an as-a-service model. Manually stitching together various network components created security gaps that hindered visibility and increased our mean-time to resolution (MTTR) for incident remediation.<\/span>\u00a0<\/span><\/p>\n

The evolution to SSE<\/strong><\/h2>\n

Our SSE transition buil<\/span>t<\/span> on our earlier <\/span><\/span>Zero Trust Access (ZTA) journey<\/span><\/span>.<\/span><\/span> While ZTA secured our distributed workforce, our SSE migration scale<\/span>d<\/span> that foundation into a unified, frictionless experience via the <\/span><\/span>Secure Access<\/span><\/span> cloud-delivered platform.<\/span><\/span>\u00a0<\/span><\/p>\n

Breaking free from the \u201coperational grind\u201d<\/strong><\/h2>\n

Our previous solution relied on twelve global locations and disparate hardware. We found ourselves at a crossroads: either invest in a costly tech refresh of our aging, end of life (EOL) infrastructure or pivot to a cloud-delivered model. We chose the latter to future-proof our acquisition tenants and better support our distributed workforce, while simplifying operations, enhancing the user experience, and increasing security.<\/p>\n

The number of components in the service chain was the real challenge. We had so many boxes stitched together. Now, with a single platform, we have best-of-breed Cisco products working in one unified fabric.<\/p>\n

How we took a unified approach<\/strong><\/h2>\n

We built upon our existing investment in Cisco Identity Services Engine (ISE) to maintain seamless authentication for VPN, proving that our SSE transformation enhances\u2014rather than discards\u2014foundational security.<\/p>\n
