Losing sensitive data can costs companies a lot whether it be by losing customer's loyalty, company's reputation or even legal consequences.
PDF files are really easy to share and a lot of online tools claim to help you to secure them but what are they worth?
What is the best way to secure your PDFs?
This article will discuss the most common ways to secure your documents and answer these questions.
Maybe one of the most popular and best ways to protect your PDFs is with a password.
There are two passwords you can set on your file:
Finally, this solution is not suitable for a PDF that you need to send to hundreds of people.
Sending the password to that many people greatly increases the risk of a leak as hundreds of people will have to use and maybe store your password.
Watermarking your PDFs is adding an image, or a text onto your content, to make it more difficult to copy or use your PDF without your permission.
This can be useful especially if your PDF is meant to be distributed to a large number of people.
A big 'CONFIDENTIAL' watermark across your content will make people more careful about the PDF, but may not be enough.
At UniquePDF, we strongly believe that adding a unique watermark on your PDF, that depends on the recipient (right image), can help increase the barrier to information leak.
This watermark contains the recipient's email address, which means that each recipient will receive a different version of the PDF with their own watermark, making it 'more personal'.

Redacting is the act of censuring or obscuring a part of a text for legal or security reasons.
This tactic can be used in PDFs to remove personal or sensible data.
However, simply adding a black line over the information that should be redacted is not enough: removing it is very easy with any PDF editor!
The best way to redact is to actually remove the piece of content.
This method can not always be used as redacting a document means removing important pieces of information.
As long as the redacting does not prevent readers from understanding the document, it can be a good solution.
However, if too many things will be redacted in your PDF, you might want to consider the two first options we saw above.
It depends on the number of peope you want to send your PDF to:
A password known and written by hundreds of people is not secured at all.
Below a dozen of people, you should lock and encrypt your PDFs with a password.
Above that number, it might be better to watermark and send them using UniquePDF or any other similar tools.
In addition to that, we have a premium feature at UniquePDF allowing you to watermark and lock your PDFs with a password, for even more security.
