A dominant certificate authority on the internet, though many of its certificates are signed as RSA Data Security. Early versions of Microsoft and Netscape browsers had RSA Data Security configured as the only trusted certificate authority. This mandated that users who want to use certificates on the internet must obtain them from VeriSign and use server software accredited by VeriSign. Current versions of the Microsoft and Netscape browsers allow users to add new certificate authorities. As older versions of the browsers are replaced, new certificate authorities (such as Thawte) have emerged.
