Global Network and Security Transformation

The internet will become the new corporate network. Frederik Janssen
Global Head of Infrastructure, Siemens

A few years ago, Siemens’ global head of infrastructure Frederik Janssen recognized that the company had reached a tipping point: With more than 64% of network traffic going to the internet, the internet had to become the company’s new corporate network. And that would require improving IT infrastructure to support cloud transformation.

Janssen’s mandate was to build for scale while reducing IT complexity. Siemens overhauled and automated infrastructure to reduce risk, and moved all 360K+ employees to the cloud, securing disparate mobile endpoints along the way. Siemens’ secure cloud transformation has reduced infrastructure costs significantly, improved the user experience for application access and cloud workloads, secured all inbound and outbound data traffic, and enabled local internet breakouts for all employees and contractors around the globe.
