Cisco IT shares lessons from consolidating fragmented security into a unified SSE platform as customer zero.
Cisco's IT engineers recount transforming a legacy, fragmented security stack into a unified Security Service Edge (SSE) platform over 12 months.
The migration cut help desk cases by 18%, achieved near-zero security incidents, and consolidated more than 20 VPN options down to two.
