Encrypt outbound email while sending the email via flow designer/Automation

[JitendraT]

Hi All,

I have a requirement to send encrypted email during Password Reset of end user manager. I am using the flow designer to generate the temp password but sending its as a encrypted email is a challenge for me. I have few questions:

1. Has anyone sent encrypted email via automation either using flow designer/workflow/BR etc. how it is been done.

2. To encrypt the outbound email, I am trying to enable S/MIME setup. I understand we will need CA certs. If any one has already implemented, can you please provide some insight. Have you used external CA or internal CA can be used as well. 

Any help appreciated. Thanks.

ServiceNow email (sent and received) is encrypted with opportunistic TLS.   Are you asking about additional encryption of specific emails?

My thoughts

1) there is limited out-of-the-box support in ServiceNow to send encrypted email via flow/BR

2) you can use S/MIME setup and yes it requires certificate, public key etc

Hi Ankur, 

Thanks for your prompt response.

My requirement is to encrypt the email content itself while it sends to recipient, hence I will need S/MIME protocol. I have started the setup. 

But my concern if wecan use this while sending the email via flow/BR. you mentioned, OOB support is limited but do we have some scripts options to achieve the same?

Thank you!

Email encryption is always for the transit so that if someone does man in middle attack they can't see the email content.

S/MIME protocol is supported and will encrypt emails sent from ServiceNow to other mailbox.

Why script is required?

The setup will take care of everything.
