Shift Left, NOT S#!T LEFT – Larry Maccherone – ASW #182

If you attempt to shift security left without adaptation, it'll feel a lot more like S#!T LEFT to the development teams but most security groups lack the mindset and skills to do it in a way that works well with modern development approaches and tools but directly focuses on gradual methodical practice and culture change.

Larry Maccherone led the Dev(Sec)Ops transformation program in the highly diverse environment at Comcast using Agile and Digital Transformation approaches. Teams that onboarded to the program had 1/7th as many vulnerabilities and incidents in production -- a result so compelling that security leadership allowed it to scale to all 600 development teams. Along the way, Larry learned some critical lessons on how to provide a gradual onramp to empowering teams to be worthy of being trusted with the security of the products they were developing.

DevSecOps Transformation at Contrast Security

Looking at Larry Maccherone’s career, you might think he can’t figure out what he wants to be when he grows up – Serial entrepreneur? Agile transformation coach? Open-source developer? Data scientist? Dev[Sec]Ops thought leader?

However, the underlying theme is that Larry has constantly been striving to create the highest performing (productivity, quality, security, etc.) software engineering teams.

At Comcast, Larry built and scaled the DevSecOps Transformation program over five years, and he’s now looking to apply what he learned doing that to help all Contrast customers and prospects.

Larry hails from Raleigh, NC, where his wife and four daughters make sure there is never a dull moment.
