Free IT Security Checkup for Ohio Businesses
Enter your business website to scan SSL, security headers, email authentication, DNS health, and more.
Heads up: when you run a scan, the domain you enter is shared with the NHM team so we can see how the tool is used and follow up if you'd like help.
What We Check
Our free IT checkup scans your business website and domain for common security and configuration issues. Enter your domain to get an instant health score covering SSL/TLS, security headers, email authentication, DNS health, and domain registration status.
SSL/TLS & HTTPS
Confirm your site loads over HTTPS with a valid, browser-trusted certificate, check HSTS, and flag insecure mixed content.
Security Headers
Check for important HTTP security headers like HSTS, X-Frame-Options, Content-Security-Policy, and more.
Email Authentication
Verify SPF, DKIM, DMARC, plus MTA-STS and TLS-RPT, to stop spoofing, improve deliverability, and enforce encrypted email delivery.
DNS Health
Check nameserver configuration and redundancy so your domain stays resolvable.
Reputation & Exposure
Check your sending IP against major blacklists and scan for accidentally exposed sensitive files and configs.
Domain Registration
Check domain expiration date, registrar information, and registration status.
