Wikipedia has a pretty good list, last I checked.  If you're really  
interested, check there; my list will not be as comprehensive.

Deployment numbers are both hard to come by and misleading.  GnuPG is  
probably overwhelmingly the largest, since it comes standard with  
pretty much every Linux distro; but there it's used principally for  
package authentication, and few people use it directly.  By  
comparison, McAfee is a niche player, but they're pretty big in the  
enterprise -- when Network Associates sold off (abandoned) the PGP  
desktop suite, they retained the right to sell PGP to enterprise  
customers.  Hence, McAfee may be a much bigger player than people think.
