Software development platform GitHub announced on Wednesday that it has hired Mike Hanley as its new Chief Security Officer (CSO).
Hanley joins GitHub from Cisco, where he served as Chief Information Security Officer (CISO) for less than a year. He arrived at Cisco via its $2.3 billion acquisition of Duo Security in 2018.
“As the largest global network of developers, GitHub is also crucial to supply chain security, giving developers the tools and knowledge to secure software following major breaches like SolarWinds,” a company spokesperson told SecurityWeek.
“As a security practitioner, this is also an exciting transition for me as much of the security community, and many of my favorite security projects, live on GitHub, like CloudMapper, stethoscope, GoPhish, and osquery,” Hanley wrote in a blog post. “I couldn’t be more excited to help secure the platform that’s made these influential projects possible and expanded their reach in incredible ways.”
GitHub, which Microsoft acquired for $7.5 billion in 2018, said last year that it had paid out a total of more than $1 million through its bug bounty program on HackerOne, where it has no maximum reward limit for critical vulnerabilities.
News of Hanley’s hire is one of several prominent industry moves announced this week, as Reddit announced that former Bank of America security executive Allison Miller would be its new CISO, and stock trading firm Robinhood has hired veteran cybersecurity practitioner Caleb Sima as Chief Security Officer.

For more than 10 years, Mike Lennon has been closely monitoring the threat landscape and analyzing trends in the National Security and enterprise cybersecurity space. In his role at SecurityWeek, he oversees the editorial direction of the publication and is the Director of several leading security industry conferences around the world.
