What is Attachment-Only Encryption?
When you send a document containing sensitive information via email, you want to make sure this document is protected in transit. While different ways of encrypting and delivering secure messages exist, what type of delivery method you choose depends a lot on customer context.
Attachment-only encryption is a non-intrusive way of securely sending a sensitive document to a recipient. The most-popular way of performing this task is to encrypt the entire email into a Secure PDF, which is only decrypted by a password or key supplied to the recipient. The documents requiring protection are “attached” embedded in the PDF and can only be decrypted once they are downloaded.
But this method of encryption only works seamlessly when the message recipient has an up-to-date PDF reader – like Adobe. Even then, many people prefer the convenience of a ‘one click’ PDF previewer.
In addition to other secure delivery methods, many contemporary encryption solutions now offer PDF serialization. This type of secure document delivery aims to mimic the light user experience of regular email – coupled with strong complex encryption.
This lighter user experience is achieved by encrypting many attachments individually, in their native format – as opposed to embedding them in a single PDF. With this delivery method, both the body of the email and the attachment look-and-feel are similar to that of a regular email user experience. But there is now password protection required to open the attachments.
In today’s business landscape, where customer experience is everything, offering this lighter encryption user experience adds additional value to your clients. Unlike traditional Secure PDF attachments, PDF serialization eliminates the need to hunt around for attachments. This creates a more streamlined user experience for your customers and leaves less room for frustration or misunderstandings.
Attachment-only encryption, with PDF serialization, has a major additional benefit: Your files stay the same in their original native format. This is good news for your recipients, who no longer need to convert or download files from different formats. From Excel spreadsheets to Word documents, this allows your customers to start work immediately – without any additional back-and-forth.
Customer experience versus customer security is no longer a conundrum – it’s just good customer service!
