Scan Domain Reputation
Check domains against threat intelligence feeds to catch malicious infrastructure, brand impersonation, and newly registered lookalikes.
Quick answer: Use the Security Scanner tool through ToolRouter to scan domain reputation directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolBrand impersonation and lookalike domains are a persistent attack vector — a domain registered yesterday that closely resembles your company's name can be used to intercept customers, harvest credentials, or send phishing emails. By the time customers report it, the damage is done.
Security Scanner's `check_domain` skill checks a domain against multiple threat feeds, returning registration age, hosting reputation, malware associations, and phishing flags. Comparing your brand's known domains against suspicious lookalikes takes seconds instead of hours of manual WHOIS and reputation lookups.
Brand protection teams, security analysts, and domain administrators use this to audit suspicious domains flagged by email filters, verify third-party partner domains, and monitor for brand-impersonation infrastructure.

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.
How to scan domain reputation
Once connected (see setup above), use the Security Scanner tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- 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 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.
