PDF Protect

Get High Level Copy Protection Security

CrypKey PDF Protect is the ideal solution for protecting your PDF documents. Distributing documents without protection means your files are easily duplicated, shared, and viewed by anyone. When you secure your PDF files with CrypKey PDF Protect, they are protected with bank-level encryption technologies. Your files are protected from 'save as', 'print screen', 'copy and paste' and other functions that compromise security. CrypKey PDF Protect automatically protects against printing via virtual machine or moving the file to another computer/USBkey.

Choose limits based on your licensing needs

PDF Protect allows you to decide how your PDF files will be used without interfering with the viewer's experience. You choose to allow or deny printing access, limit the number of days it can be used, or set a document expiry date. With the electronic option, you can even limit access based on number of concurrent users.

Choose your distribution method

CrypKey PDF Protect is compatible with many distribution options. Your PDF files can be used securely through online download, email, and CDs. CrypKey eLocKey USB keys are the perfect solution for users who require portability and use on multiple computers.
