We are using .Trailer - legal disclaimers from this vendor and it has worked well. Also, we are currently evaluating .Crypt for e-mail encryption and have had great results. Our next step will be testing .Wall - their SPAM software.
It is an integrated package and you can buy licenses for each one separately and I have found their price to be very competitive based on the features/functionality.
Here is a link to the vendor site ==>
