DefendDomain finds web addresses made to look like a company's own and gets them taken down. Criminals register these lookalike domains, such as an address one letter away from the real one, to send fake invoices with new bank details, copy websites, run fake online stores and steal logins.
DefendDomain checks around 500 lookalikes of each domain it protects every hour, and watches public certificate logs as new entries appear. When a lookalike is used in an attack, one click sends the evidence to up to 12 places that can act on it, including the registrar, the host and the email provider. It also checks a company's own domains every day for gaps that make impersonation easier.
Founded in 2025 by James Bending and David Batey, DefendDomain is ISO 27001 certified and won Cyber Security Start-up of the Year at the teiss Awards 2026. It has sales in London, engineering in Oxford and customers in the US, UK, EU and Asia-Pacific.
