Working with digital documents is part of day-to-day working life for most people. In many companies, a day without Word documents or Excel tables is almost unthinkable. The same goes for the platform-independent PDF file format, which provides an excellent solution for combining text, images, and graphics in one document.
But for all these files, there’s one rule: If you want to protect them from unauthorized access, then you must put the right security measures in place. Whether the file is saved to the hard drive, a cloud server, on a web server, or is being sent by email, does not matter, because as soon as intruders access the file they’re also able to read it without any problems – if the file is not encrypted. For sensitive information like customer details or internal company files this could prove catastrophic. That’s why certain PDFs should always be encrypted or password protected. We’ll show you how this works in this article.
