Mwende Window Snyder, better known as Window Snyder (born 1975) is an American computer security expert[1] currently working as the Chief Security Officer at Square, Inc..[2] She has previously been a top security officer at Apple, Fastly, Intel and Mozilla Corporation. She was also a Senior Security Strategist at Microsoft. She is co-author of Threat Modeling, a standard manual on application security.


Snyder is the daughter of an American father and a Kenyan-born mother, Wayua Muasa. She goes by her middle name Window; her first name is used only by family members. She graduated from Choate Rosemary Hall in 1993 and has served on their board.[3] At college, she got a computer science major, and during that time got interested in cryptography and crypto-analysis[4] and started actively working on the topic of cyber-security with the Boston hacker community in the 1990s, building her own tools and getting familiar with multi-user systems.[5]

She then pursued this career path as one of the first computer scientist to specialize in cyber security, and to proactively try to bridge the gap between corporations and the security researchers often termed 'hackers[4]'. Until 2002, Snyder was Director of Security Architecture at @stake. Subsequently, she worked as a senior security strategist at Microsoft in the Security Engineering and Communications group. During this time, she was a contributor to the Security Design Lifecycle (SDL) and co-developed a new methodology for threat modeling software, as well as acting as security lead and signoff on Microsoft Windows XP Service Pack 2 and Windows Server 2003.[4] She also created the Blue Hat Microsoft Hacker Conference, an event bringing together engineers at Microsoft and hackers for a dialogue about the security of Microsoft's software.[6] After leaving Microsoft in 2005, she worked as a principal, founder, and CTO at Matasano Security, a security services and product company later acquired by NCC Group.[7] She joined Mozilla in September 2006.[8][9]

On December 10, 2008, Snyder said that she would be leaving Mozilla Corporation at the end of the year.[10] On March 1, 2010, Snyder began work at Apple Inc.[11]

In 2015, Snyder became chief security officer at content distribution network Fastly.[12]

Intel's Software and Services Group senior vice president and general manager, Doug Fisher, announced in July 2018 that Snyder would become the company's Platforms Security Division's chief security officer, vice president and general manager.[13][14] She has since left Intel and in May 2019 joined Square, Inc.[2]
