Often the first measure anyone takes of a profession is their list of professional certifications. In the IT industry, the CompTIA (Computer Technology Industry Association) A+, Network+ and Security+ certifications are considered the standard in profession certifications.
CompTIA A+ certifies expertise in the maintenance and servicing of PCs, mobile devices, laptops, operating systems, peripherals and more. Companies such as Dell, HP, Ricoh, Sharp and Xerox recommend or require
CompTIA Network+ for their networking technicians. It is a technical prerequisite option for IT technicians seeking to join the Apple Consultants Network, and is recognized by the U.S. Department of Defense.
Organizations that employ CompTIA Security+ certified staff include Hitachi Information Systems (Japan), Trendmicro (Philippines), Lockheed Martin, the U.S. State Department, Prestariang Systems Sdn. Bhd. (Malaysia) and U.S. government contractors such as EDS, General Dynamics and Northrop Grumman. CompTIA Security+ is one of the options for certifications required by the U.S. Department of Defense, for military personnel or military contractors engaged in information assurance activities.
