Security is not optional anymore. These free security tools help you verify the essentials — SSL certificate validity, HTTP security headers, password strength and suspicious domains — before attackers find the gaps.
Run a quick check whenever you launch a site, change hosts, or just want peace of mind. Findings come with plain-English explanations so you always know what to fix next.
Headers like Content-Security-Policy and HSTS tell browsers how to handle your site securely. Missing ones are among the most common — and most fixable — findings.
Enter your domain in the SSL checker. It reports expiry dates, issuer details and chain issues that could trigger browser warnings.
They perform only safe, non-intrusive checks against public information — no exploitation, no intrusion, just clear visibility into your security posture.
