Though often recommended by security researchers as a good alternative to Adobe Reader, Foxit's site freely lists the security bulletins on its product, but they are far fewer than those for Adobe Reader.

"We develop our code from scratch, so 99% of the time we don't share the same vulnerabilities as Adobe Reader," Bryant said.

Also, Foxit, by necessity lacks some of Adobe Reader's features, such as the ability to display 3-D images in CAD-created PDFs, said Bryant. But he said that most of the missing features were for niche users.

The company is very close to releasing two enterprise products. One is called Foxit Phantom, an all-in-one suite that includes a PDF creator, editor and more. That is meant to compete with Adobe's various Acrobat suites.

The second is the Foxit Security Suite, which helps companies implement Digital Rights Management (DRM) on PDFs using permissions managed by Microsoft Corp.'s Active Directory technology. This, said Bryant, will also be cheaper than Adobe's current server software.
