DefendDomain - 2026 Pricing, Features, Reviews & Alternatives

DefendDomain is state of the art at detecting domain impersonation and finding look-alike domains. It protects fast-growing businesses across the US, UK, EU and APAC from the domains criminals register to defraud their customers, phish their staff and copy their websites.

Impersonation attacks start with a domain that looks like yours. DefendDomain watches around 500 look-alikes of each domain you own across 240+ TLDs and re-checks them continuously, including the email-only domains that never host a website but are set up to send fake invoices and payment requests. Four more layers catch what domain monitoring alone misses: embedded markers that fire when a copy of your site loads elsewhere, content fingerprinting that finds cloned and paraphrased pages in search results, real-time certificate transparency monitoring, and a daily A to F grade of your own domains' email authentication, DNS and TLS.

Every threat arrives with the evidence: screenshots, WHOIS, DNS, hosting and certificate details. Alerts go to email, Slack, Microsoft Teams, SMS, webhooks and SIEM tools.

Takedowns are unlimited on every plan, and DefendDomain has a 100% takedown success rate to date. Each takedown goes out across up to 12 channels in parallel and is checked hourly, with follow-ups and escalation built in. Run it yourself, or choose the fully managed service: with your approval up front, our team decides on and runs takedowns for you, and checks with you when a case is unclear.

DefendDomain is ISO/IEC 27001 certified.
