Free Website Security Scanner — Protect Your Site in Seconds
Most websites have at least one critical security misconfiguration that they don't know about. AuditAI checks your HTTPS setup, security headers, and exposed paths — instantly, for free.
Scan My Site Now →Security Headers We Check
These six HTTP response headers are the industry-standard baseline for web security. Many sites are missing at least three of them.
Content-Security-Policy (CSP)
High risk if missingPrevents XSS attacks by whitelisting which sources can load scripts, styles, and media. Without CSP, any injected script can run with full page permissions.
HTTP Strict Transport Security (HSTS)
High risk if missingForces browsers to only connect over HTTPS for a set period. Prevents protocol downgrade attacks and cookie hijacking on open Wi-Fi networks.
X-Frame-Options
Medium risk if missingBlocks your page from being embedded in an iframe on another site — prevents clickjacking attacks where a malicious overlay tricks users into clicking hidden buttons.
X-Content-Type-Options
Medium risk if missingTells browsers not to MIME-sniff responses. Without this, a browser might execute an uploaded image file as JavaScript if an attacker renames it.
Referrer-Policy
Low risk if missingControls how much referrer information is sent when users click links off your site. Prevents leaking sensitive URL parameters to third-party analytics or ad networks.
Permissions-Policy
Low risk if missingRestricts access to browser APIs like camera, microphone, and geolocation. Especially important if you embed third-party scripts or iframes.
Why Security Headers Matter for Every Site
Security headers are one line of server configuration that take minutes to add but meaningfully reduce your attack surface. Google, Mozilla, and OWASP all recommend them as a baseline for any public-facing website — not just e-commerce or banking.
Without HSTS, a visitor connecting from a coffee shop can have their session hijacked even if your site has an SSL certificate. Without CSP, a single compromised ad script can steal form data from your contact page.
For sites using shared hosting, missing headers are especially dangerous — a vulnerability in another tenant's site can sometimes be exploited to inject malicious content into yours.
Common Exposed Paths We Detect
Misconfigured deployments often leave sensitive files publicly accessible. AuditAI probes these common paths and flags anything that returns a 200 response.
Environment variables — API keys, database credentials
WordPress admin panel — brute-force target
Git config — may expose repo URLs and credentials
PHP configuration dump — reveals server internals
Generic admin panel — common attack surface
Mac OS directory listing — reveals file structure
