Protect your business from email impersonation and phishing attacks
SpoofDefence helps businesses secure their email domain with SPF, DKIM, and DMARC, then supports ongoing protection with monitoring and phishing awareness training.
Check your domain protection
Enter your business domain for a quick public check of DMARC, SPF, and DKIM signals.
Criminals do not need access to your mailbox to impersonate your domain.
Weak or missing email authentication can make it harder to control unauthorised mail claiming to come from your business. That can damage trust with clients, suppliers, and staff.
Focused protection for trusted business email
Technical controls reduce impersonation risk, while awareness training helps staff recognise phishing attempts before they become incidents.
