Mine got `100/100 - Good security configuration detected</li> <li> <em>Key Checks:</em> <ul> <li>✅ Website URL looks valid</li> <li>✅ HTTPS is enabled</li> </ul> </li> <li> <em>Security Recommendations</em> - Ex: "Make sure the website uses recommended security headers"</li> <li> <em>Scan History</em> - Saves past scans with date, time, and score. You can also clear it.</li> </ul> <p><em>Why I built this:</em><br> As a beginner, I wanted to understand how basic website security works. So many sites still run without HTTPS. This tool makes it easy to check the basics fast.</p> <p><em>Tech Stack:</em><br> <code>HTML</code>CSS `JavaScript</p> <p><em>Important:</em><br> This scanner only does basic checks. It does NOT do penetration testing or deep server-side header inspection.<br><br> ⚠️ <em>Please only scan websites you own or have permission to test.</em></p> <p><em>Want me to check your website?</em><br> Drop your URL in the comments or message me directly and I’ll send you a free security report.</p> <p><em>WhatsApp me here</em><br> <a href="https://wa.me/2348144514422" rel="noopener noreferrer">https://wa.me/2348144514422</a> or whatsapp me@+2348144514422</p> <p><em>What's next for v2:</em><br> Thinking of adding SSL certificate expiry check + common security headers scan. <br> What other features would you add? </p> <p>Let me know what you think 👇</p> webdev javascript cybersecurity learning
