“I have been a subscriber to your Global Terror Book Summaries for the past year... ManTech International Corp. has personnel in 41 countries and your summaries are invaluable to me as ManTech's Chief Security Officer for enhancing awareness of threats in our Senior Leadership. I feed the summaries to our CEO and President and this generates interesting and valuable discussions concerning threats to our company personnel and the security strategies required to counter those threats. The summaries are a great bargain for me and help me generate interest and investment in a coordinated security program that reduces the risk to ManTech.”

—Michael C. Tillison, Vice President Corporate Security ManTech International Corporation
