The Rising Cost of Insecurity

In 2025, a website hack happens every 39 seconds. For small businesses, the average cost of a data breach has skyrocketed. But it's not just about money—it's about trust. If users see a "Not Secure" warning or get redirected to a malicious site, they will never come back.

Most vulnerabilities aren't in your code logic, but in your server configuration. Missing security headers are the digital equivalent of leaving your front door unlocked.

The Hidden Risks

Many developers focus on code but neglect the invisible shield of HTTP headers:

  • Missing HSTS: Allows attackers to downgrade visitors to an insecure HTTP connection.
  • Weak CSP: Opens the door for Cross-Site Scripting (XSS) attacks.
  • No X-Frame-Options: Makes your site vulnerable to Clickjacking.

The Solution: Website Security Audit

Manually checking headers is tedious. That's why we built the Website Security Audit tool. It performs a deep scan of your site's security configuration, similar to Mozilla Observatory but with easier-to-understand insights.

What Do We Monitor?

  1. 🛡️ HTTP Security Headers: We check for strictly-transport-security (HSTS), x-content-type-options, x-frame-options, and more.
  2. 🔐 Content Security Policy (CSP): We analyze your CSP to ensure it effectively blocks malicious scripts without breaking your site.
  3. 📜 SSL/TLS Configuration: Verify that your certificate is valid and using strong encryption standards.
  4. 📊 Vulnerability Grading: Get a simple A to F letter grade so you know exactly where you stand.

How to Check Your Security Score

  1. Navigate to the Website Security Audit.
  2. Enter your domain name.
  3. Click Run Security Audit.

You'll receive a comprehensive report highlighting exactly which headers are missing and how to fix them. You can even export a PDF report to share with your development team or clients.

[!IMPORTANT] Don't Ignore Low Grades: If your site gets a 'D' or 'F', prioritize adding the missing headers immediately. It's often just a few lines of config in your Nginx, Apache, or Vercel next.config.js.

Security isn't a "set and forget" feature. It requires constant monitoring. Start by knowing your baseline.
