The CCIE Security written exam was the result of the foresight and perseverance of several Cisco TAC engineers working out of an office near Santa Cruz, California. Initially, the CCIE Security test was seen as unnecessary because security was not viewed as a core technology of the Internet. However, as a result of the vision of some strong managers within the Cisco Customer Advocacy group and some highly damaging security attacks, this mindset has changed. The CCIE Security exam is now viewed as a "must have" core credential by many Cisco customers. I've been fortunate enough to have been not only involved in the initial creation of the CCIE Security test, but to also have participated in all three versions of the test since then.
