K&N CyberShield
Free Security Checkup

See what an attacker sees.

We check the security configuration your domain exposes to the whole internet — email spoofing protection, your certificate, security headers, and whether your domain shows up in known breaches. You get a scored, branded report with the fixes that matter most.

This looks only at public records. It does not scan your devices, your network, or anything behind a login. It is not antivirus.

Passive checks only. We never scan your devices. Consent version 2026-07-18.2.
