Security Yearbook 2021 Now Available

From PRNewswire. Author, industry analyst, and founder of IT-Harvest, Richard Stiennon, announced the publication of Security Yearbook 2021: A History and Directory of the IT Security Industry. The book is available at It was produced and printed in hardcover with the support of sponsors Anitian and Cofense.

2020 was a year of dramatic developments for the cybersecurity industry. There were two notable failures of funded startups added to the chapter on failures. 271 vendors received new funding for a total of $10 billion in new investments. 225 vendors were acquired with private equity claiming the majority of M&A activity. Complete lists of new funding and M&A are published in the new book.

The impact of COVID-19 slowed growth for many vendors as they expected demand to drop. But the move to work-from-home increased demand for technology to protect newly distributed organizations. Zero trust networking and SASE solutions saw tremendous growth in 2020.

Security Yearbook is the only published history of the IT security industry. This year the 2021 edition includes 2,615 vendors listed by country and category. The percent change in headcount is provided for each vendor. “This is one of the most valuable metrics for determining a vendor’s health,” Stiennon said. “Growth in head count is a great metric for judging a company’s momentum. By monitoring head count I can also get early warning of trouble at a vendor.”

The result of over a decade of research, Security Yearbook 2021 starts at the early days of RACF, ACF2, Check Point Software, Symantec, and McAfee, coming right up to the present day.

Security Yearbook 2021 is not a summary of technologies; this is a book filled with rich histories of the vendors and the people behind the companies – the misfits and pioneers – that have built today’s $300+ billion cybersecurity industry.

The individual stories of industry pioneers are recounted in their own voice alongside the author’s market research and analysis, making this a one-of-a-kind read and an indispensable guide to the entire IT security industry.

Security Yearbook has become my life’s work, said Richard Stiennon. “It is a full-time job just keeping up with the space. In this book I incorporate everything I have learned in 25 years of being part of an industry that grows over 24% every year.”

“Security Yearbook” is already an indispensable reference for industry veterans and CISOs. Industry analysts, Wall Street analysts, professors, and marketing teams use it for product selection, and identifying trends. The industry is subdivided into 16 different sectors, including Network, Endpoint, Data Security, GRC, and MSSPs. New sectors such as Security Analytics, Threat Intelligence, and Deception will be of particular interest to practitioners who are looking to understand advanced cyber defense tools and practices.
