How Secure Is Your Business Website?
Run a free security assessment, identify publicly visible risks, and discover practical ways to strengthen your digital infrastructure.
No registration. No payment. No intrusive testing.
What this checks / limits
HTTPS and redirects, TLS connection, security headers, software version disclosure, cookie flags, mixed content, email DNS protections (SPF, DMARC), DNSSEC, CAA, mail servers and security.txt.
This assessment only covers publicly observable security conditions. It uses a few ordinary page requests and DNS lookups — no logins, form submissions, port scans or attack payloads. It cannot certify that a website is free from vulnerabilities.
