Web Scanner

A web scanner thoroughly examines websites to find security flaws, unprotected areas, and other weaknesses. Web Application Firewall (WAF) implementations and necessary security headers are checked for as part of this procedure.HTTP response headers known as security headers instruct the browser to apply safeguards, assisting in the defence against risks such as clickjacking, content sniffing, cross-site scripting (XSS), and unsafe content loading. These headers are easy to implement and significantly improve browser-side security.A Web Application Firewall simultaneously keeps an eye on and filters incoming traffic to prevent server-side threats such denial-of-service attempts, SQL injection, and remote file inclusion. A WAF protects the application backend, whereas headers protect the user experience. A web scanner that checks for both guarantees multilayer protection, assisting administrators in securing both ends of the web communication channel and lowering vulnerability to contemporary cyberthreats.

Frequently Asked Questions

Find answers to the most commonly asked questions below.

What are HTTP security headers?

Security headers are instructions sent from the server to the client (browser) to enforce security policies such as blocking unsafe scripts, preventing clickjacking, and forcing HTTPS connections.

What is a Web Application Firewall (WAF)?

A WAF is a security layer that filters, monitors, and blocks malicious HTTP/HTTPS traffic to and from a web application. It protects against threats like SQL injection, XSS, CSRF, and bot attacks.

Why scan for both WAF and security headers?

  • Security headers harden your site at the browser level.
  • WAF protects your server from common attack patterns.

Scanning both gives a complete picture of your application's defensive posture.

Are security headers enough without a WAF?

No. While headers protect the client-side/browser environment, they do not prevent backend attacks like SQL injection or DDoS. A WAF adds a much-needed layer of server-side defense.

What should I do if my scan shows missing headers or no WAF detected?

  • Add or fix missing headers based on best practices.
  • Consider deploying a WAF or enabling one through your cloud provider or host.
  • Re-scan after updates to verify fixes.

How frequently should I scan my site?

  • After major site updates.
  • After WAF configuration changes.
  • Regularly as part of your vulnerability management process.

What happens if I don't use security headers?

  • Your site may be vulnerable to client-side attacks like XSS.
  • Browsers might load unintended scripts or styles.
  • Clickjacking and data leakage risks increase.

My site is missing some headers. Does that mean it's insecure?

No, however essential headers such as Content-Security-Policy, Strict-Transport-Security, and X-Content-Type-Options are highly recommended. They defend against common attacks, whereas certain previous headers, such as X-XSS-Protection, are now deprecated.
