GeoTrust is the world's second largest SSL certificate provider. According to their website, more than 100,000 customers throughout the world (150 countries overall), use GeoTrust for some type of SSL encryption security. Their SSL certificates come with a fast delivery time and enable up to 256-bit SSL encryption. Another great feature of the GeoTrust SSL certificate is their site seal. The site seal offers a customized display of how much security is provided with an individual SSL certificate.

The company also offers some great features, including a powerful management portal, world-class continuous support, and bulk pricing for GeoTrust Partner companies, as well as enterprise-level users.

However, we found this not to be true. What we realized was that this company has been traded off over the years, possibly creating some confusion about who actually owns GeoTrust.

Currently, Symantec owns GeoTrust. They were acquired, along with Verisign, in 2010, as a $1.28 billion dollar deal with Symantec.

Thawte is an Internet company that is based out of South Africa. They are a certificate provider for X.509 certificates. Mark Shuttleworth started the company in 1995 and, to date, they are the fifth largest public certificate issuer on the Internet. Thawte was originally run from a garage. They originally aimed to provide secure servers for customers, but ultimately began to focus on certificates, building one of the largest businesses in the industry.

The company has largely grown through sales, mergers, and acquisitions. In 1999, Verisign bought Thawte for $575 million. These two companies had the first certificate for Netscape browsers during the browser wars.

An interesting fact about Thawte is that Shuttleworth has gone on to do some pretty amazing things after the Thawte sale. Shuttleworth used his money from the Thawte sale to help fund the Ubuntu project, an alternate browser for smart devices and computers.

GlobalSign is an SSL provider with full certificate authority. In addition to providing SSL products for websites, they also provide identity services. The company was founded in 1996 and is currently owned by GMO Cloud K.K., which is based out of Japan. GMO Cloud offers a wide array of identity service solutions and web security products for small- to enterprise-level businesses.

GlobalSign claims that their services are based within a powerful infrastructure, backed by global data centers. The company has placed itself as a major player within a $14.4 trillion market, making secure networked connections among organizations, people, data, and other things that will be required to have a trusted and fully managed identity.

We also found that GlobalSign is a company that sets first-time industry standards. We found that GlobalSign was the first certificate authority to improve page load time for secured HTTP pages. Also, IPv6 is going to be one of the big things to worry about in coming years as the nature of IPs change over time. GlobalSign is the first company to build certificates for customers that offer IPv6-compliant revocation (page loading) services.

Trustwave is a company that provides Internet security for businesses.

In 2014, they were named one of the leaders in managed security services by Forrester Research. They are based out of Chicago, IL and have global offices in London, Brazil, and Australia. One of the neat facts about the company is that they are the only authorized PCI Forensic Investigators in all regions of the world.

The company filed for IPO in mid-2011, but the company still remains private. There are more than 1,000 employees with the company. Trustwave is on the verge of becoming a global-based company. In early April 2015, Singapore Telecommunications announced their intentions to purchase this company for nearly $1 billion. This acquisition promises to raise Trustwave’s standing as a global Internet provider of SSL certificates.
