Free Security Tools
Test your security posture, right here
Six tools built by our team — no signup, no data collection where it matters. Most run entirely in your browser.
One graded report: SSL, headers, and email spoofing defense
Domain Security Report Card
Enter any domain and get a combined security grade covering SSL/TLS certificate health, HTTP security headers, and SPF/DKIM/DMARC email authentication — the checks a real security review starts with.
Geolocation, ISP, and risk signals for any IP
IP Address Lookup & Threat Check
Look up any IPv4/IPv6 address to see its geolocation, ISP or hosting provider, and known risk indicators — useful for investigating suspicious logins or traffic.
See the real delivery path and spoofing verdicts
Email Header Analyzer
Paste raw email headers to see the actual hop-by-hop delivery path and whether SPF, DKIM, and DMARC passed — the fastest way to tell a real email from a spoofed one.
Check a password against known breaches — privately
Pwned Password Checker
Uses Have I Been Pwned's k-anonymity API: only a partial hash of your password is ever sent, so the password itself never leaves your device.
