Supply Chain Email Security Report

This tool will provide a basic report that will give you an idea of the security of your supply chain.
The tool reports on the existance of three key security controls:

DMARC
SPF
MTA-STS

Just because a control is in place, and the syntax is correct, it doesn't mean that the control is effective and still needs to be validated, however if something fails, it's either not there or not effective.

Instructions

All fields are required.

Please enter your name and business email address in the corresponding fields. The report will be delivered to the email address supplied here.

In the domains field, please enter the list of domains searated with commas (and no spaces).
e.g. myaccountant.co,mybank.com,mywidgetmanufacturer.ae

Which domains should I check?

You should check every company that might invoice you including:

Acountants
Lawyers
Insurers
Banks
Suppliers
HR Partners & Outsourcers
Caterers

You can also check key customers to see if they are vulnerable as part of your risk management strategy - if they lose money, they may not be able to pay your invoices.
