A veteran technology marketing executive with 25+ years of experience in high-tech, Walker specialises in performance-marketing, demand generation and building leading brands for technology and cyber security companies. Most recently, she served as CMO at Bugcrowd where she earned positive market validation from leading industry analysts and established Bugcrowd as the leader of Crowdsourced Cybersecurity. Prior to that, she spent five years as CMO at Infoblox, the leader in next generation DNS management and security where she led a data-driven transformation of its marketing team and transformed the company’s brand from a data-centre networking provider to a modern, cloud-first networking and security company.

“Mobile devices are an increasing focus of cyber criminals. Last year, there was a 466% increase in exploited, zero-day vulnerabilities used in active attacks against mobile endpoints. But it is not just mobile endpoints introducing risk into corporate systems - 42% of organisations reported unauthorised apps and resources accessed enterprise data,” said Shridhar Mittal, CEO, Zimperium. “As Zimperium enters a high-growth phase to help more organisations protect against increasing threats to their endpoints and applications, Sammie is the perfect person to join our leadership team as CMO. She brings extensive experience in driving growth, building strong teams and accelerating pipeline for networking and security companies. She is a world-class leader, and we are excited for her to join us as we continue our next phase of growth."

“Organisations are realising that the mobile threat is real as more and more of them suffer catastrophic damage after falling victim to mobile attacks far outside their traditional security protections,” said Sammie Walker, CMO, Zimperium. “As the only security platform that can protect the entire mobile ecosystem – from applications to endpoints – Zimperium has a unique opportunity to continue building on its leadership position in the mobile security space while helping organisations around the world become more secure. By scaling our marketing efforts, we can build on Zimperium’s winning track record and bring our solutions to an even wider audience.”
