Registered typosquatting domains
High-priority domains to register
These high-risk typosquatting domains are currently available. Consider registering them defensively.
Security recommendations
API endpoints
GET /v1/typos/threats?domain=example.com
Also available: /v1/typos/report (full report), /v1/typos/quick (fast check)
Interactive intelligence tool
Run the check, then ship the workflow
Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Review decision-ready signals
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Automate the workflow that works
Use the request and response examples to turn a one-off check into an API call or recipe.

Key Features
About brand protection
This tool performs real-time availability checking on all generated permutations. It identifies which typosquatting domains are actually registered (threats) vs available (defensive opportunities), and analyzes DNS activity to detect active threats.
Detect typosquats
Each registered typosquat is scored 0-100 based on: visual similarity (homoglyphs score highest), DNS activity (active sites are more dangerous), and suspicious patterns (e.g., "login" or "secure" in the domain name).
Domain Watchlist
Use the Brand Monitoring API (/v1/brand-monitor) to establish a baseline and receive alerts when new typosquatting domains are registered. Requires a free account.
Example request
GET /v1/typos/threats?domain=example.comExample response
{
"threats": [],
"defensive_opportunities": []
}Built on the same API
The browser experience previews DomScan's structured endpoints, so teams can validate a use case before writing code.
Frequently asked questions
What makes this different from basic typosquatting detection?
This tool performs real-time availability checking on all generated permutations. It identifies which typosquatting domains are actually registered (threats) and which are available (defensive opportunities), and analyzes DNS activity to detect active threats.
What does the threat score mean?
Each registered typosquat is scored 0-100 based on: visual similarity (homoglyphs score highest), DNS activity (active sites are more dangerous), and suspicious patterns (e.g., "login" or "secure" in the domain name).
Should I register all defensive opportunities?
Focus on critical and high risk domains first. These are the ones most likely to be used in attacks. The tool prioritizes them for you.
How can I monitor for new threats over time?
Use the Brand Monitoring API (/v1/brand-monitor) to establish a baseline and receive alerts when new typosquatting domains are registered. Requires a free account.
