Eight tools, one engine
Pick a tool, get an answer
Every tool on this page queries the same threat intelligence that powers our paid plans. What you see is what our customers see.
Security Headers
Analyze HTTP security headers on any public URL and get an instant grade. Catches missing CSP, HSTS, X-Frame-Options, and the full modern header checklist.
SSL Checker
Verify SSL/TLS certificate validity, expiration date, issuer, and trust chain. Catches expired, misconfigured, or incomplete certificates before your users do.
DNS Security
Check SPF, DKIM, and DMARC records for any domain. Verifies your email authentication posture and flags misconfigurations that let spoofers through.
IP Reputation Lookup
Check any IP address against our 224M+ threat record database. See risk score, geolocation, ISP attribution, and behavioral category in real time.
Domain Checker
Evaluate domain reputation and threat indicators. Catches newly registered suspicious domains, known phishing infrastructure, and look-alikes targeting your brand.
Email Validator
Identify disposable, temporary, and suspicious email addresses. Protects signup forms from abuse and keeps throwaway accounts out of your funnel.
URL Scanner
Examine any URL for phishing, malware, and malicious redirects. Runs the full Panthero analysis pipeline on a single link - safer than clicking.
Report an IP
Caught an attacker on your own infrastructure? Submit the IP and a threat category. Verified reports feed Panthero's behavioral models and protect every other customer on the platform.
Why free?
Because good security starts with checking
The biggest security wins in our industry come from people checking the boring stuff - headers, certificates, DNS records, IP reputation. Most teams skip it because the tools are scattered across ten different sites.
We put them all in one place, made them free, and pointed them at the same intelligence engine we sell to our paying customers. No quotas, no signups, no dark patterns - just the tools you need, when you need them.
What you get, free forever
- All eight tools, every time
- No signup, no card, no email capture
- Powered by 224M+ threat records
- Same engine as our paid plans
- EU-hosted, GDPR-compliant
Need more than spot checks?
The free tools are great for one-off checks. When you need continuous protection across every request, every server, and every application - that's what our paid plans are for.
