What's New in Security Yearbook 2025?

Sixth edition of the only history of the cybersecurity industry

Every year I scramble to pull together the Security Yearbook so it can get to the printer as early as possible. This year I was ready to go on January 1. I have to wait until all the data is in for the year before spitting out the Directory of all the vendors from the IT-Harvest Dashboard.

In November I went to Lake Huron for four days to lay out every chapter and identify updates. I do my best writing when I have a horizon to stare at.

Freighters are a bonus.

In order to ensure that copies of Security Yearbook 2025 would be available by RSAC at the end of April, Wiley gave me until January 13th to wrap up the manuscript. Then there were multiple rounds of edits with the final proofs to review by March 6. Yesterday, April 5, I received my author’s copies! Only four weeks to print 1,000 copies. When I was doing this on my own it took 12 weeks once I was in the printer’s queue. No surprise that Wiley has more pull with a book printer than I do.

First copy of Security Yearbook 2025

If you order today you can expect to receive your copy by May 5 (in the US). Or, if you are going to be in San Francisco in three weeks you can get a signed copy, compliments of the following sponsors:

BforeAI has a suite at the St. Regis. I will be there Tuesday, April 29 from 10-12. On Wednesday they have a get together at Wine Down restaurant. I will be there from 10-12.

Also on Wednesday you can find me on the Expo floor. I will be signing books in the booth of Aurascape from 2-3 PM. Then finishing the day in the booth of ESET from 4-6:30.

There is one more opportunity Tuesday afternoon but I am waiting on the exact time.

What’s new in this edition? Every chapter of course is updated. The M&A and funding chapters have complete lists of all the 2024 transactions. The Directory has 4,000+ vendors by location and category. Each vendor’s headcount and change in headcount is included.

There is a new chapter highlighting the Cyber 150, a list of the fastest growing cybersecurity companies in 2024. Next year I will report on what happened with the 2025 Cyber 150 and publish a new list.

Not to leave out the smaller vendors I also create a new chapter for the 2025 Fast 50 under 50.

If you have been collecting them since 2020 (the Covid edition) this is what they look like all together.

And in the cyber section of my bookshelf.

Note how each edition gets bigger. Security Yearbook 2025 is 509 pages. So leave room in your luggage to carry at least one home from RSAC.
