Welcome to our new annual edition of GSN’s Buyer's Guide, a convenient buyers directory that puts at your fingertips contact information for more than 1,800 companies. This volume is easy to use.

The Suppliers List presents in alphabetical order all of the companies and organizations that appear anywhere in the directory. The Industry Categories roster breaks the government security marketplace into four main sections – Disaster Preparedness & Recovery, IT Security, Physical Security and Security Services – and then further divides those sections into industry categories and sub-categories. If you’re looking for a specific company, please turn to the Suppliers List. If you want to see several vendors involved in a particular category or sub-category, please use the Industry Categories roster.

Again this year, our editorial team worked tirelessly to gather, categorize, refine and proofread this data in an effort to publish an indispensable tool for the entire government security marketplace. Several people deserve our special thanks. Mark Kaplan, GSN’s art director, Josh Martin, our managing editor, and Virginia Asman, our graphic artist, have massaged this data with great care and precision.

World Business Media, LLC, the proud parent of the Source Guide, also publishes a monthly award-winning print edition called GSN: Government Security News, a weekly e-newsletter called GSN’s Homeland Security Insider and we maintain a constantly-updated Web site at www.gsnmagazine.com

All of our products are free of charge to qualified readers with a professional interest in homeland security. If you are such a person, we invite you to sign up for our publications and information products and encourage you to become an active participant in the dialogue we foster within the homeland security community.
