Career Thoughts

I am humbled and honored to have the opportunity to manage and run one of the biggest and most active forums on the Internet dealing with cyber warfare and cyber security – CSFI (The Cyber Security Forum Initiative). With over 16 years of cyber security experience, I continue to actively raise Cyber Warfare/Cyber Security awareness worldwide. I have worked as a Chief Security Engineer for AT&T, where I designed and approved secure networks for MSS. I have also consulted for several governments, military and private institutions on best network security practices throughout my career.

CSFI and its divisions CSFI-CWD (Cyber Warfare Division), CSFI-LPD (Law and Policy Division) and CSFI-WD (Wireless Division) continue to grow and expand with more than 60,000 information security members.

One of my personal goals is to serve our security community to the best of my abilities, in the protection and defense of our American national security interests, the American people, and that of our international partners. I am always ready to serve and to give of my time and skills to help our society with the growing problems we experience in cyberspace. I thank God and my family for the opportunities I have had in life and the most precious of all opportunities, which is the chance to serve others. I love what I do, and I appreciate all the support I have received from friends, family and our CSFI members.


Paul de Souza, CSFI Founder Director
