Financial documents at your business can be copied from computer to computer, without restriction. This is why you need advanced security tools for your documents.

  • Send legal documents to clients, or send sensitive quotes or price lists without worrying that unauthorized parties can read them.

  • Reliable PDF password protection enables such a critical level of security. PDF Reader makes it easy to implement passwords throughout your company within your workflows and business processes.
