The ex-CEOs of BT Global Services and Ericsson North America have got new roles at Wandera and Verizon respectively, while Cisco’s Chairman has announced he will not stand for re-election.
Luis Alvarez (pictured) was sacked by BT earlier this year in the fallout from the accounting scandal at the firm’s Italian subsidiary, which saw 20 percent wiped off the UK-based operator’s share price.
In his first role since leaving BT, Alvarez becomes Strategic Advisor to mobile security provider Wandera.
The UK-based vendor provides app scanning, network security and analytics solutions to enterprises.
“Mobile cyber threats are a growing phenomenon, and it's been impressive to learn how Wandera has been building world-class technologies to both identify and protect against them,” Alvarez said.
“I've witnessed Wandera's success in securing some of the largest enterprises in the world, and now I'm joining the growing crowd of industry experts that recognise the powerful differentiation of their unique cloud approach.”
Meanwhile, former Ericsson North America CEO Rima Qureshi has been appointed Chief Strategy Officer for Verizon Communications.
She will take over responsibility for the development and implementation of Verizon's overall corporate strategy, including business development and strategic investments, on 6 November, the US operator said.
Verizon Chairman and CEO Lowell McAdam said: "The addition of Rima is another game-changer for Verizon.
“She's a visionary leader, with a global perspective and a thorough understanding of our industry and where it's headed."
Qureshi joins former boss Hans Vestberg, who joined Verizon as President of Network and Technology earlier this year.
Another well known European telecoms exec, former O2 UK CEO Ronan Dunne, is Group President of Verizon Wireless.
Finally, John Chambers will not seek re-election as Chairman of Cisco when his term ends in December this year.
CEO Chuck Robbins will replace Chambers, who will be given the honorary title of Chairman Emeritus.
Chambers joined the US-based vendor in 1991 and served as CEO from 1995 to 2015.
Robbins said: "John's brilliant mind, compassion and charismatic leadership have helped shape Cisco for over 20 years, and for that we are all grateful.
"John's influence on the industry is immense and he built Cisco around a culture of integrity and innovation that will continue to serve our employees, partners and customers for decades to come.”
