Website Security Scanner & Vulnerability Probing
Security is a direct Google ranking factor (HTTPS). A secure site protects user credentials, transaction details, and corporate data from malicious actors. Websites with weak security headers, expired SSL/TLS certificates, or exposed database ports face high risks of database leakage, malware infection, and organic traffic drops due to browser warning pages.
How to harden your website security
- Implement HTTPS & HSTS: Ensure all traffic is encrypted via TLS 1.3, and use HTTP Strict Transport Security (HSTS) headers to enforce secure connections.
- Declare Security Headers: Add Content-Security-Policy (CSP), X-Content-Type-Options, and Referrer-Policy headers to prevent cross-site scripting (XSS) and clickjacking attacks.
- Close Exposed Database Ports: Ensure database ports (like 3306 for MySQL or 5432 for PostgreSQL) are closed to public traffic and only accessible via private networks or VPNs.
Security Checklist
SSL Certificate Validity
Always renew TLS certificates before they expire to prevent browsers from displaying scary warning screens to visitors.
Exposed Services threat
Ports like 22 (SSH), 21 (FTP), and 3389 (RDP) should never be exposed to public port scans without rate-limiting and keys.
