Headshot of Eleanor Saitta

Eleanor Saitta leads Systems Structure Ltd., a security architecture and strategy consultancy with media, finance, healthcare, infrastructure, and software clients across the US and Europe.  She's worked in security since 2003, covering everything from core security engineering and architecture work for Fortune 50 software firms to cross-domain security for news organizations and NGOs targeted by nation states.

This diversity of experience has led Saitta to combine two threads in her security guidance.  The first approach looks at security outcomes for humans and organizations, with an emphasis on culture design for resilience, security-appropriate frames for thinking about risk, and how operational changes can shift the balance of power away from adversaries.  The second approach looks to modern infrastructure-as-code systems to be able support harder security guarantees, rather than statistical mitigations, and a pragmatic but principle-centric architectural approach.

Saitta was previously the security architect for and has worked for a number of commercial consultancies (Bishop Fox, IOACtive, and others).  She is a co-founder and developer for Trike, an open source security ecosystem modeling methodology and tool which partially automates the art of security analysis, and has contributed to the Briar and Mailpile secure messaging projects. She's on the advisory boards of the Freedom of the Press Foundation and the Calyx Institute, both organizations that look at freedom in the media and security online.  She writes about security and systems resilience and is also a regular speaker at industry conferences; past venues include O'Reilly Velocity, KiwiCon, ToorCon, CCC, Hack in The Box, and HOPE, among others.
