Telstra chief information security officer, Mike Burgess, has resigned from the telco after spending nearly four years in the role to “explore other opportunities," according to a Telstra spokesperson.
His last day with the telco will be November 4, while Telstra searches a replacement globally.
“Mike established proven and effective security capabilities that play a critical role in keeping our customers' data safe and our networks secure," the Telstra spokesperson said.
"He is leaving Telstra with the right strategy and capabilities developed and implemented – and as company, we will continue to build on these."
Prior to joining Telstra, Burgess served a four-year stint in the private sector as deputy director of cyber and information security for the Australian Signals Directorate.
In this role, he offered his expertise in reviewing and planning Australia’s wider cyber-security strategy.
Burgess was particularly acknowledged at Telstra for his feat in co-authoring and implementing 'The Five Knows of Cyber-Security' - an internal strategy he pioneered to manage the cyber-security risk within Telstra ‘from the Board down.’
