You can read this book in any order that suits you (though we don't recommend upside down or backwards). Foolish Assumptions It's been said that most assumptions have outlived their useless- ness, but here are a few assumptions nevertheless. You have a technical background and work for an organization that, like many, is looking for a better way to manage your net- work and security challenges in a multi-cloud, hybrid enterprise. As such, this book is written for technical readers with a general understanding of cloud, networking, and security concepts. Perhaps you're an IT executive or manager such as a chief infor- mation officer (CIO), chief technology officer (CTO), or chief information security officer (CISO), VP of IT, IT director, or net- work or security manager. Or perhaps you're a cloud, network, or security architect or engineer. If any of these assumptions describe you, then this is the book for you! If none of these assumptions describe you, keep reading anyway! It's a great book and when you finish reading it, you'll know quite a bit about SD-WAN and cloud security!
