Acknowledgments

I had the pleasure of working with a fantastic team of editors on this, my first technical book. The team at Pearson has been extraordinary, and has my sincerest thanks. Ellie Bru guided me through the technical-review process and provided great feedback on content and layout. Thank you to Mandie Frank, who managed this book through its iterations in final editing. Special thanks go to Brett Bartow, without whose encouragement and guidance, this book would not have even been started.

I owe a great debt to my technical editors, Ben Hartwell and Tim Draegen. Their long experience and technical expertise shaped this guide into the final product you see here. They questioned everything, asked for clarification on my statements, and suggested better examples. This book is all the better because of their work. Thank you again!

For more than eight years, I’ve been a part of an extraordinary team, first at IronPort Systems and now in Security at Cisco. I’ve never worked harder or had more fun at a job. It has been an honor serving with such an intelligent, motivated, and downright crazy group of individuals. My thanks to everyone involved with designing, building, selling, and supporting the ESA product.
