The SANS Institute is a private U.S. company that specializes in internet security training. It was founded in 1989 and provides computer security training, professional certification through Global Information Assurance Certification (GIAC), and a research archive - the SANS Reading Room. It also operates the Internet Storm Center, an Internet monitoring system staffed by a global community of security practitioners. The trade name SANS (deriving from SysAdmin, Audit, Networking, and Security) belongs to the for-profit Escal Institute of Advanced Technologies.
SANS training 
When originally organized in 1989, SANS Conferences functioned like traditional technical conferences showcasing technical presentations. By the mid-1990s, SANS evolved into a more commercial format offering events which combined training with tradeshows and vendor-oriented marketing. As of 2008[update] SANS offers computer and internet security courses in a variety of formats including a virtual classroom (SANS vLive), online training and assessments (SANS OnDemand) and live training via Community SANS, a Local Mentor Program, and the original Conference format. Free webcasts and email newsletters (@Risk, Newsbites, Ouch!) have been developed in conjunction with security vendors. The actual content behind SANS training courses and training events remain "vendor-agnostic." Vendors cannot pay to offer their own official SANS course, although they can teach a SANS "hosted" event via sponsorship.
Certifications related to SANS training courses are offered by SANS-operated GIAC.
SANS Technology Institute 
As of 2008[update] SANS has branched out into the SANS Technology Institute, a degree-granting educational organization based on SANS training. SANS continues to offer free security content via the SANS Technology Institute Leadership Lab  and IT/Security related leadership information.
SANS instructors have contributed to many security-oriented books, such as:
