PrismEmail is a service of Vault Information Services LLC (VIS), a Colorado Limited Liability Company.

VIS was founded in 1993. In our early days, we were one of Denver's first Internet Service Providers (ISP) long before the Internet craze began. By the time America Online registered its domain, we had been providing Internet service in the Denver-area for more than a year. By 1998 we had anticipated the consolidation of ISPs as well as an eventual move to high-bandwidth cable and wireless connectivity. Given the option of investing growing sums of money in a market that would be less and less profitable, we sold off our dial-up business and focused on website hosting as well as consulting projects.

In 1997, VIS entered the embedded market by introducing specialized development software for the MCS-51/8052 microcontroller in the form of our 8052 Simulator for Windows. That summer we also launched 8052.com, a site dedicated to 8052 development which is still the premier technical site for 8052 information. In 2000, we released Pinnacle 52--a full Integrated Development Environment for the 8052.

In 2001, VIS launched a technical site for information related to barcodes, BarcodeIsland.com. In the tradition of 8052.com, this site targets the technical community that works with barcodes. The site provides a large amout of technical information on barcodes that previously was scattered over many sites all over the world.

In 2002, VIS was subject to the negative effects of spam first-hand and realized it was definitely a growing problem in need of a solution. Development began on Prism Email which was completed and made available to the public in spring 2003.

VIS was on the Internet before AOL, Yahoo, NetZero, Usa.net, Prodigy, Lycos, Hotmail, UUNet, Amazon, and eBay. We were here before all of them and we'll be here for years to come.
