ARgon for Email

ARgon uses unique Adaptive Redaction technology from Clearswift and tackles the problems caused by traditional Data Loss Prevention (DLP) solutions by automatically removing only the content which breaks policy and then sending the rest of the email and attachments onwards. This enables continuous collaboration, safe in the knowledge that critical information is protected.
DLP effectiveness is determined by the accuracy and the workflow of the product. Many DLP solutions are purchased and never deployed because they are too hard to configure or they generate too many false positives, resulting in increased operational overheads and decreased productivity through disrupted communications.

ARgon can be used in environments with no DLP solution or to augment an existing one. In both cases, ARgon removes next generation information threats from both inbound and outbound email. For those with an existing DLP solution, ARgon reduces the false positives by automatically removing the content which would cause the DLP solution to ‘stop & block’ the communication.

    There are three key features within Adaptive Redaction that ARgon for Email utilises are:

  • Data Redaction: Removes visible content that breaks policy from email and attachments.
  • Document Sanitisation: Removes document meta-data, revision history, etc.
  • Structural Sanitisation: Removes active content embedded in received documents.


ARgon is deployed between the email hygiene (and/or DLP) service and the internal email server.

  • ARgon for Email uses standard SMTP messaging technology to enable compatibility with any email gateway solution.
  • The email gateway service can be provided by any vendor and located on-premise or hosted.
  • The email server can be Exchange, Lotus Notes, Domino, or Groupwise.
  • Proof of Value trials can use either ‘Side Car’ or ‘In Series’ deployments.


There are three key features within Adaptive Redaction that ARgon for Email utilises are:

  • IT personnel – to focus on harmful viruses and malware;
  • Business/audit personnel to focus on sensitive content violations.


Argon for Email comes with default policies to enable risk reduction immediately after installation. These default policies can then be further enhanced, if higher levels of granularity or compliance are required.

Adaptive Redaction Feature Default Policy
Data Redaction Remove PII and PCI from all outgoing email and documents
Document Sanitisation Remove all document properties, revision history and fast save information
Structural Sanitisation Remove all active content from incoming and outgoing documents

Authorised Release

In the case where information has been removed by Adaptive Redaction in order to prevent a policy being breached, but the information is actually required to be sent, a simple click on a link in an email to the senders’ manager (or an authorised administrator, compliance officer etc.) can be enacted. Integration with Microsoft Active Directory or an LDAP service enables the solution to understand the organisational relationships to make this happen.


A number of standard reports ship with the ARgon solution. These can be used to report on the number of emails and attachments which have had the policy applied. They can also be used in monitor mode, when no policy action is taken, to show the number of communications which would have been affected. This is typically done when the system is in trial or first deployed as part of employee education.
