Factsheet protect domains against phishing

Prevent e-mail spoofing and phishing by protecting your domains with e-mail authentication. Phishing involves sending e-mails with misleading content to get the recipient to download malicious software or divulge information. Attackers resort to a range of techniques to improve their chances of success.

Falsifying domain names (‘spoofing’) is one such method. Spoofing makes it more difficult for recipients to recognise phishing e-mails because it appears as if such e-mails were sent from the e-mail address of a reliable organisation. Organisations that do not protect their domain names against e-mail spoofing might cause damage to recipients due to abuse and suffer reputational damage themselves as a result. Moreover, it may harm the correct delivery of e-mail. Receiving mail servers increasingly block e-mails without e-mail authentication so recipients do not receive them.
