They are very responsive to our requests and go the extra mile. Stops Windows print screen, stops screen grabbers and prevents printing to file drivers this stops users creating unprotected files such as PDF files or XPS files. Unlike Adobe permissions document controls cannot be removed — regardless of how strong the password you use Adobe permissions can be removed in seconds and this can be easily done without using any password removal tools.

You only have to protect the PDF once for all users and the correct information is inserted depending on the user who has opened the document. Lock PDF files to machines — PDF files are automatically locked to machines authorized devices so they cannot be shared. Once a user activates their license they can only view PDF files from that device. PDFs can also be locked to a country location, a domain, or a range of IP addresses on a user or global basis.

For example, you might only want to allow users to use your protected PDF files from an office location. You can use either passwords or certificates to lock a PDF file from opening but they both have their problems. A more secure and easier way to lock a PDF from opening by unauthorized users is to use encryption with licensing controls and transparent key management. You therefore do not have to worry about key distribution. This is what Locklizard uses along with device locking to prevent encryption keys and theforefore your documents from being shared.

Anyone that has the document open password hint: any user you share the PDF file with needs it can remove the PDF restrictions in seconds.

The problem however is that you have to upload your unprotected PDF files to a cloud server where they could be compromised. This might be OK for non sensitive or confidential PDF documents but most businesses do not want to expose their documents to a third party which is why they are protecting them to begin with.

So while online PDF locking tools may seem attractive, they are actually less secure and provide only simple password protection which is easily removed. There are no passwords to enter or remove or certificates to manage. When you protect a PDF file , a corresponding key for the document is relayed to a server and stored encrypted.
