TPG Telecom has brought its internal security and cloud capabilities together under a single function, with general manager of technology security Lee Barney’s role impacted by the restructure.

Barney revealed his departure from TPG Telecom on LinkedIn after almost three years in the role.

“This week marks the end of my time at TPG Telecom,” Barney wrote. “As the business reshapes its leadership priorities, I leave knowing the team is well-placed for what comes next.” 

iTnews understands that Barney’s departure is the result of a restructure that has led to the formation of a new function called Technology Security, Cloud & End to End Architecture.

The purpose of the restructure is to create better clarity and alignment between TPG’s security and cloud development teams.

“We are bringing security and cloud together to design and build security-native cloud solutions and boost the security capability adoption across the business,” a TPG Telecom spokesperson confirmed to iTnews.

Secure-by-design is a key principle of the government’s current cyber security strategy, which organisations – particularly those in critical infrastructure sectors – are being asked to adopt.

It’s not clear who is leading the new function; TPG’s spokesperson declined to comment.

It’s understood there are no immediate plans to recruit a replacement for Barney.

Barney was instrumental in the telco standing up a cyber centre of excellence or CCoE, which came online at the end of last year.

The Sydney-based facility focuses on finding vulnerabilities in telco and IT equipment, developing exploits and applying mitigations.

It is home to TPG’s red and blue teams, representatives from Ericsson, Nokia and TCS on 90-day rotations, and researchers from UNSW.

Barney is also credited with leading an uplift in TPG’s security posture during his time with the telco.
