Free instant analysis of any domain: SSL certificates, security headers, DNS health, technology stack, and overall security score.
Checks SSL, headers, DNS, tech stack, and performance in seconds.
Encrypts data between your visitors and your server. Without it, passwords and credit cards travel in plain text. We check validity, strength, and expiration.
HTTP response headers that tell browsers how to behave. CSP stops XSS attacks. HSTS prevents downgrade attacks. Missing headers = easy targets.
SPF and DMARC records prevent email spoofing. Without them, attackers can send fake emails that appear to come from your domain. DNSSEC prevents DNS hijacking.
Knowing what software runs your site matters for security. Outdated WordPress plugins, old PHP versions, or exposed server info can be exploited by attackers.
Slow sites lose visitors. We measure response time, redirects, and page size. Every extra redirect is a security risk and a speed penalty.
A composite score from 0-100. A = excellent, B = good, C = fair, D = poor, F = critical. One failing grade can drag your overall score down significantly.
Analyzing domain security...
Your site shows "Not Secure" in browsers. Visitors see warnings. Search engines rank you lower.
Fix:
Get a free SSL certificate from Let's Encrypt (auto-renews) or purchase from DigiCert. Most hosting providers (Cloudflare, SiteGround, WP Engine) include SSL for free.
Your site lacks protections against XSS, clickjacking, and content injection. These are one-line fixes that block entire categories of attacks.
Fix:
Add headers in your web server config or use Cloudflare (free plan includes most headers). For WordPress, install Sucuri or Wordfence to add them automatically.
Anyone can send emails pretending to be from your domain. This damages your reputation and makes phishing possible using your brand.
Fix:
Add TXT records in your DNS. Use MXToolbox SPF Generator to create the right record. For DMARC, start with v=DMARC1; p=quarantine; rua=mailto:[email protected]. Google Workspace and Microsoft 365 provide guided setup.
Slow sites lose 40% of visitors. Google uses speed as a ranking factor. Every second of delay costs conversions.
Fix:
Enable caching with Cloudflare (free CDN). Compress images. Use a fast host: WP Engine for WordPress, SiteGround for general hosting. Minify CSS/JS.
Old PHP versions, unpatched WordPress plugins, or exposed server banners give attackers a roadmap to exploit your site.
