About IT-Harvest Press
The publishing imprint of the cybersecurity industry's data house.
IT-Harvest Press turns the deepest dataset in cybersecurity into books worth keeping on the shelf — yearbooks, histories, and field guides written for the people who build, fund, and defend the industry.
Our story
Built on data, written for the long shelf.
IT-Harvest was founded in 2005 by Richard Stiennon as a research firm dedicated to one question: how do you make sense of an industry as vast and fast-moving as cybersecurity? The answer became the IT-Harvest Dashboard — the only platform tracking the entire market, vendor by vendor and product by product.
IT-Harvest Press is the imprint where that research becomes long-form. While the Dashboard answers questions in real time, the Press captures the analysis, history, and context that deserve a permanent record — from the annual Security Yearbook, the definitive directory of the industry, to standalone works on cyberwar, secure cloud transformation, and the rise of AI in security.
Every title we publish draws on the same underlying data, so our books aren't opinion pieces — they're grounded in a continuously updated map of the whole industry. That's what lets us produce directories and analyses no one else can.
