As I understand it:
If you can open the PDF without a password then so can anyone who intercepts the message.
If there is a password, then the PDF will require a dictionary and or brute-force break, but provided that the password is not a common word or too short this may take some time.
Rights Management ES offers the highest level of security, and it's a fairly safe bet that a PDF would be useless if anyone intercepted it.
It really depends on the security applied to the PDF itself. If the PDF has no security, and the email itself is not secure then someone may be able to read it (just like any other attachment).
You can use Acrobat or LiveCycle to apply password protection to the PDF, or you can apply Digital Rights Management based encryption. It really depends on your infrastructure and user audience
Question - appreciate your patience, I'm a bit of a novice. I am trying to find out if I can convert a "for sale" print product (e.g. report etc) to a PDF and protect and prevent it from distribution and/or downloading?
You can protect something from downloading by not putting it on a
public web site. That's all. That may sound a smartass answer, but the
way a PDF file is viewed is that first it is downloaded, then read. So
every file you look at is downloaded.
I'd suggest investigating the ADEPT platform, may be useful if you are producing a paid publication:
I've never used the service so I can't say how suitable it would be, but it seems to be aimed at your requirement.
