How to Scan Domain Reputation with Claude
Scan Domain Reputation with Claude and ToolRouter. Check domains against threat intelligence feeds to catch malicious infrastructure, brand impersonation, and newly registered lookalikes.
Tool
Use Claude with Security Scanner to investigate suspicious domains and get an interpreted risk assessment. Claude can compare a domain's registration age, hosting context, and threat feed flags to assess whether it looks like legitimate infrastructure or an impersonation attempt — and explain the reasoning.

Steps
Once connected (see setup above), use the Security Scanner tool:
- Provide the domain or list of domains to investigate.
- Ask Claude to run `check_domain` via `security-scanner` for each one.
- Ask Claude to assess registration age, hosting reputation, and any phishing or malware flags.
- Request a verdict: legitimate, suspicious, or actively malicious — with the key signals that drove the conclusion.
Example Prompt
Try this with Claude using the Security Scanner tool
Use security-scanner to check these domains: paypa1-support.com, toolrouter-login.xyz, secure-bankofamerica.net. For each one, tell me the registration age, threat feed verdict, any phishing or malware flags, and whether it looks like a brand impersonation attempt.
Tips
- Check registration age first — domains registered within the last 30 days combined with brand keywords are a strong impersonation signal.
- Compare suspicious domains to your known legitimate domains side by side so pattern differences are visible.
- Ask Claude to explain which signals are strongest versus circumstantial so you can prioritize takedown actions.
