The Outlook plugin is a powerful encryption plugin that allows you to specify conditions for the message you choose to encrypt.    


Setting specific encryption conditions will override any encryption settings configured on SpamTitan.


The plugin can be configured to automatically prompt the sender to consider encrypting a message when a message is sent to an email address outside the organization.



The following table displays conditions that can be set on a per message level using the plugin.



Encryption Method
                   Secure Portalrequires account registration with password.
                   Secure Portal High Securityrequires a verification code provided by the sender.
                   Secure  Portal Low Securitydoes not require authentication.
 Encryption confirmation 

 

Receive an encryption confirmation  (this option is only valid when your domain encryption policy is not configured to send a confirmation by default).

 


Message Expiration



Assign an expiration (deletion) time period for a message that should expire outside the default expiration period.

 





Which encryption method should I use?



Although all available encryption methods meet most regulatory requirements, being able to choose the encryption method allows the sender to balance the level of security with the requirements put upon the recipient to read the encryption email.


TLS 1.2  when possible, an encrypted message will be delivered to the recipient’ without requiring the recipient to interact with the secure portal.


This method is perhaps the least secure of the available encryption method options.  TLS or Transport Layer Security, only ensures that the email is encryption between the EncryptTitan encryption gateway and the host that the recipients DNS MX record instructs email senders to send e-mail too.


EncryptTitan can only assure that the message is encrypted when being transported to the recipient's inbound mail host.  After being transported security to the inbound mail host, it is entirely possible that the e-mail may go through other mail hosts, unencrypted, before finally being delivered to the recipients inbox.  


In addition, we are not able to verify that any replies from the recipient will be  encrypted.



 Secure Portal requires account registration with password.


This method is a commonly used method of encryption and provides a high level of security.  


When selecting this method of encryption, if this is the first time the recipient has received an encrypted message from your organization, the recipient will  receive a notification message that provides account registration instructions.  


The registration process, ensures that the recipient has ownership of the email account the encrypted message was sent.


Secure Portal High Security requires a verification code provided by the sender. 


 A very useful encryption method when sending an email that contains content that requires an exceptional high level of security.  


By selecting Secure Portal High Security, the email  will deliver to the secure portal.  The sender will receive a one-time password (OTP) (by way of email) that they will then convey to the recipient.


Because this method requires the the sender provide the OTP to the recipient, it is the most secure method of delivery.


Secure Portal Low Security does not require authentication.


When the occasion arises where you wish to send an encrypted email but don't want the recipient to have to register or even enter a password; making it super simple for the recipient; this is the encryption method to consider.  


This method still provides a secure portal for the recipient to retrieve the message from and provide the recipient with a way to reply back security; all without requiring the recipient to undertake any additional authentication measures.
