Secure Envelopes Overview

You may already know that attachments to email are insecure; however, it may surprise you to learn just how insecure it really is.

  • Did you know that email attachments which you thought were deleted years ago may be sitting on servers half-way around the world?
  • Did you know that your attachments can be read and modified in transit, even before they reach their destination?

Secure Envelopes allows the sender or 'creator' of any type of electronic attachment (eg Word, PDF, Media File, Excel etc) to be able to encrypt and manage the attachment for the term of its life.

Through our software we allow the creator to place various business rules around the life of the envelope before it is sent and also allowing the creator to alter the envelope after it is sent.

This means that not only can the creator enter individual recipients to the envelope, the creator can CHANGE the rules even after the envelope has been sent. This means ANY recipients usual access rights can not only be changed - but totally REVOKED post distribution - anywhere, anytime.

Some of the key benefits of Secure Envelopes include:

  • Access control to encrypted files outside of company domain or firewall
  • Simple 2mb installation with easy to use interface
  • Revoke recipients access post distribution, any time, through a web browser
  • Access Audit reports on who accessed the envelope and when
  • Secure encryption of attachments without the user handling keys - just press 'encrypt'
  • Separation of access control rules and encryption keys from the encrypted envelope
  • Total key and access control managed 'server side' - no key ring management by users.
  • API for bulk Secure Envelope creation

Some of the security issues we have solved include:

  • Eavesdropping
  • Invasion of Privacy
  • Attachment Modification
  • False Attachments
  • Message Relay
  • Repudiation (Sender denies that they sent the attachment and/or the Receiver denies they received the attachment)

Key management - We have separated the keys that unlocks or de-codes the secure envelope, from the secure envelope. The reason a file can be hacked is because the key resides within the file and thus, with enough 'brute force' the key can be broken.

With our technology there is not only no key within the secure object, but other elements to make it impossible to hack as a standalone file - in fact "hackers don't even know where to start".

Why do we exist? - The need and the right to protect our privacy as individuals continues to be challenged by the needs of the State and the need to protect the broader community.

In a business context, the challenge to protect information and customer data in a collaborative "global village" is yet to be solved. In the meantime, some governments are increasing the burden on corporations to protect the right to privacy against the need to improve the bottom line.

In government, the challenge to be seen to provide or protect individual freedom and meet the needs of government continues to be a delicate one.


Our Competitive Edge - The major competitive edge we have over other software is that our software separates the encrypted file from the access rules and keys - a revolution in file security. The access rules and encryption keys reside on a server and the encrypted envelope moves separately - but it always refers back to the server before allowing access.
