Verisign also offers a range of security services, including managed DNS, distributed denial-of-service (DDoS) attack mitigation and cyber-threat reporting. In 2010, Verisign sold its authentication business unit – which included SSL certificate, PKI, Verisign Trust Seal, and Verisign Identity Protection (VIP) services – to Symantec for $1.28 billion. The deal capped a multi-year effort by Verisign to narrow its focus to its core infrastructure and security business units & solution provider for Verisign was Baysquare Technology Pvt Ltd. Verisign's former CFO Brian Robins announced in August 2010 that the company would move from its original location of Mountain View, California, to Dulles in Northern Virginia by 2011 due to 95% of the company's business being on the East Coast.〔(Verisign shifts headquarters to Virginia )〕 ==History== Verisign was founded in 1995 as a spin-off of the RSA Security certification services business. The new company received licenses to key cryptographic patents held by RSA and a time limited non-compete agreement. The new company served as a certificate authority (CA) and its initial mission was "providing trust for the Internet and Electronic Commerce through our Digital Authentication services and products". Prior to selling its certificate business to Symantec in 2010, Verisign had more than 3 million certificates in operation for everything from military to financial services and retail applications, making it the largest CA in the world. In 2000, Verisign acquired Network Solutions,〔("VeriSign buys domain firm" )〕 which operated the , and TLDs under agreements with the Internet Corporation for Assigned Names and Numbers (ICANN) and the United States Department of Commerce. Those core registry functions formed the basis for Verisign’s naming division, which is now the company’s largest and most significant business unit. In 2002, Verisign was charged with violation of the Securities Exchange Act.〔(【引用サイトリンク】title= The Emerson Firm Announces Class Action Lawsuit Against VeriSign Inc. on Behalf of Investors — VRSN )〕 Verisign divested the Network Solutions retail (domain name registrar) business in 2003, retaining the domain name registry (wholesale) function as its core Internet addressing business.〔("VeriSign To Sell Network Solutions, Exit Registrar Business" )〕 For the year ended December 31, 2010, Verisign reported revenue of $681 million, up 10% from $616 million in 2009.〔("VERISIGN REPORTS 10% YEAR-OVER-YEAR REVENUE GROWTH IN 2010" )〕 Verisign operates two businesses, Naming Services, which encompasses the operation of top-level domains and critical Internet infrastructure, and Network Intelligence and Availability (NIA) Services, which encompasses DDoS mitigation, managed DNS and threat intelligence. Verisign's share price tumbled in early 2014, hastened by the U.S. government's announcement that it would "relinquish oversight of the Internet's domain-naming system to a non-government entity".〔(【引用サイトリンク】title= VeriSign Inc.
