Help us get fake websites and fake invoices taken down
DefendDomain finds web addresses made to look like a company's own and gets them taken down when they are used against it. We are a small team, founded in 2025, with sales in London and engineering in Oxford. Four roles are open now.
How we work
We are a young company. These are the habits we want to keep as we grow.
Security first
Customers trust us with details of the attacks against them. We are ISO 27001 and Cyber Essentials certified, and everyone on the team completes security training.
Build, then learn
We ship small changes often and learn from how customers use them, rather than debating them in meetings.
Close to customers
Our customers deal with real attacks, such as fake invoices sent in their name. We talk to them often and build for the problems they bring us.
Across borders
We have customers in the US, UK, EU and Asia-Pacific, and some of our roles are open across time zones.
Why join us
Join early
You would be one of the first people on the team. What you build and decide will shape the product and the company.
Work that stops fraud
Fake web addresses are used to send fake invoices, copy websites and run fake job offers in companies' names. You will help find them and get them taken down.
A modern stack
We build with Next.js, TypeScript and AI models, and deploy continuously.
Flexible working
Some roles are remote, others are hybrid from London or Oxford. Each role below says which.

Find out who is pretending to be you
A fake domain has to exist before the first fake invoice can be sent. The free scan checks 150+ lookalikes of your domain to see which already exist.
The scan usually takes a couple of minutes and we email you the report. No account, no card.
