Johannes has written a good article, on Sans Internet Storm, on how to aid the fight on phishing emails – set up “Brand Indicators for Message Identification” (BIMI) for your email. We did this a few months ago over at Octagon Technology (I still have to set it up here on Smart Thinking). It is not difficult just tricky to get every stage right. Our logo is not a trademark so we skipped that step.
If you cannot manage then get in contact via Octagon’s contact page, and they can set it up for you – and get the required, correctly formatted logo organised as well.

Also you could join our course, to equip you and your team with the knowledge to combat phishing emails and social engineering attacks.
