Add one more to the list of executives departing Cisco. Tony Shakib, vice president of the Internet of Things (IoT) Vertical business unit, has left for Microsoft, where he's general manager of a group called IoT and Intelligent Cloud.

Shakib made the move last month, according to his LinkedIn profile. CRN, in a report published today, confirmed Shakib's departure.

Large companies lose executives all the time, but Cisco has seen a steady flow of notable departures since Chuck Robbins took over as CEO in 2015. This was expected, considering the end of John Chambers' 20-year term as CEO was a major life event for the company.

Shakib's eight-year tenure at Cisco is modest compared with that of other departing execs. The group led by Mario Mazzola had joined Cisco in 1993, although they technically left the company three times to run their spin-in startups. Wim Elfrink and Kelly Ahuja had each been with Cisco for 18 years when they decided to leave.

Cisco's IoT Vertical business targets industrial IoT use cases, serving customers in specialized areas such as oil or transportation. Shakib became vice president of that group in 2013, according to his LinkedIn profile.

A 16-year Nortel veteran, Shakib joined Cisco in 2009 after CEO stints at AOptix and smart-grid startup Zensys; the latter was acquired by Sigma Designs in 2008.
