Full report
DNS & Email Security
83/100SPF record configured
SPF record found: "v=spf1 include:spf.protection.outlook.com -all".
DMARC record configured
DMARC record found with policy "reject": "v=DMARC1; p=reject; pct=100; rua=mailto:BingEmailDMARC@microsoft.com;".
CAA record configured
CAA record found — only authorized Certificate Authorities can issue SSL certificates for this domain.
DKIM record configured
No DKIM record found for common selectors. DKIM cryptographically signs outgoing emails, making them verifiable and preventing tampering in transit.
Fix: Configure DKIM in your email provider (Google Workspace, Microsoft 365, etc.) and publish the TXT record they provide at {selector}._domainkey.bing.com
MTA-STS (email transport security)
No MTA-STS record found at _mta-sts.bing.com. Without it, email delivery to your domain could silently fall back to unencrypted connections.
Fix: Implement MTA-STS: add a TXT record at _mta-sts.bing.com with value "v=STSv1; id=YYYYMMDD01" and publish a policy file at https://mta-sts.bing.com/.well-known/mta-sts.txt
IPv6 support
Domain has an AAAA record — IPv6 is supported.
BIMI record
No BIMI record found. BIMI lets your brand logo appear in email clients that support it — a trust and branding signal for recipients.
Fix: BIMI requires DMARC with p=quarantine or p=reject. Then add a TXT record at default._bimi.bing.com: v=BIMI1; l=https://yourdomain.com/logo.svg
DNSSEC
DNSSEC could not be verified via this automated check (PHP DNS resolvers strip DNSSEC data). Check with your domain registrar or use dnsviz.net to verify.
SSL & HTTPS
85/100HTTPS / SSL enabled
The website is accessible over HTTPS.
SSL certificate valid
Certificate is valid and expires on 2026-08-01 (102 days left).
HTTP redirects to HTTPS
HTTP requests are not being redirected to HTTPS.
Fix: Configure a permanent (301) redirect from HTTP to HTTPS.
HSTS header configured
Strict-Transport-Security header found with max-age=31536000. includeSubDomains is set.
No weak cipher suites
Server does not accept known weak cipher suites (RC4, 3DES, EXPORT, NULL).
TLS 1.0 and 1.1 disabled
Server only accepts TLS 1.2 or higher. Deprecated TLS versions are not supported.
Content & CMS
100/100No mixed content detected
No insecure HTTP resources (scripts, images, stylesheets) found in the page HTML.
CMS admin panel not publicly accessible
No publicly accessible CMS admin interface found at common paths.
CMS version not exposed
No CMS version information found in the page source.
Subresource Integrity (SRI)
No external scripts or stylesheets without Subresource Integrity hashes detected.
No open redirect
No open redirect detected via common redirect parameters.
Directory listing disabled
Directory listing is not enabled — files cannot be browsed directly.
Security Headers
60/100Server version not disclosed
The Server header does not expose version information.
Content-Security-Policy
CSP header enforced: (policy is set)
X-Frame-Options
X-Frame-Options: SAMEORIGIN — protects against clickjacking.
X-Content-Type-Options
X-Content-Type-Options header is missing.
Fix: Add X-Content-Type-Options: nosniff to prevent browsers from MIME-sniffing responses.
Referrer-Policy
No Referrer-Policy header found.
Fix: Add Referrer-Policy: strict-origin-when-cross-origin to control how much referrer info is sent.
Permissions-Policy
Permissions-Policy header found — browser feature access is restricted.
Cookie security flags
One or more cookies are missing security flags: MUID (missing: HttpOnly); MUIDB (missing: Secure, SameSite); _EDGE_S (missing: Secure, SameSite); _EDGE_V (missing: Secure, SameSite); SRCHD (missing: HttpOnly, Secure, SameSite); SRCHUID (missing: HttpOnly, Secure, SameSite); SRCHUSR (missing: HttpOnly, Secure, SameSite); SRCHHPGUSR (missing: HttpOnly, Secure, SameSite); _SS (missing: HttpOnly, Secure, SameSite); ULC (missing: HttpOnly, Secure, SameSite); _HPVN (missing: HttpOnly, Secure, SameSite).
Fix: Set HttpOnly (prevents JS access), Secure (HTTPS only), and SameSite=Lax or Strict on all cookies.
Cross-Origin-Opener-Policy
No Cross-Origin-Opener-Policy (COOP) header found. Note: COOP can break popup-based flows (payments, OAuth) and browser back/forward cache.
Fix: Consider adding Cross-Origin-Opener-Policy: same-origin if your site does not use cross-origin popups.
Cross-Origin-Embedder-Policy
No Cross-Origin-Embedder-Policy (COEP) header found. Note: COEP breaks external embeds (YouTube, maps, ads) that don't send CORP headers.
Fix: Consider adding Cross-Origin-Embedder-Policy: require-corp only if your site does not embed third-party content.
Performance & SEO
100/100Fast server response time (TTFB)
Time To First Byte: 57 ms (measured from our scanner server) — excellent.
Response compression enabled
Compression is enabled (br) — reduces transfer size and speeds up page loads.
robots.txt present
A robots.txt file was found and is accessible.
XML sitemap present
An XML sitemap was found — helps search engines discover and index your pages.
security.txt present
No security.txt file found at /.well-known/security.txt or /security.txt.
Fix: Create a security.txt file (RFC 9116) at /.well-known/security.txt to provide security researchers with a responsible disclosure contact.
Critical issues (4)
What is this?
An HTTP to HTTPS redirect automatically sends visitors who type http:// (or click an old link) to the secure https:// version of your site.
Why does it matter?
If HTTP is not redirected, some visitors may unknowingly browse your site without encryption. It also causes duplicate content issues for SEO since the same page exists on both http:// and https://.
How to fix it
Add a 301 redirect in your server config: Nginx: return 301 https://$host$request_uri; Apache: Redirect permanent / https://yourdomain.com/ Or in .htaccess: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
What is this?
X-Content-Type-Options with the value "nosniff" tells browsers not to guess (sniff) the content type of a response, but to strictly use the Content-Type header the server sends.
Why does it matter?
Without this header, a browser might interpret an uploaded text file as JavaScript if it contains script-like content — a technique attackers can exploit to run malicious code even when file uploads are allowed.
How to fix it
Add this header to all responses: X-Content-Type-Options: nosniff Nginx: add_header X-Content-Type-Options "nosniff" always; Apache: Header always set X-Content-Type-Options "nosniff" Laravel: add to middleware or in .htaccess.
What is this?
The Referrer-Policy header controls how much information about the originating page is included in the Referer header when a user navigates away from your site or when resources are loaded.
Why does it matter?
Without a Referrer-Policy, the full URL of the current page (which may include session tokens, user IDs, or sensitive paths) is sent to external sites in the Referer header. This can leak private information to third-party analytics, CDN providers, or ad networks.
How to fix it
Recommended value: Referrer-Policy: strict-origin-when-cross-origin (sends origin only for cross-origin requests, full URL for same-origin) Nginx: add_header Referrer-Policy "strict-origin-when-cross-origin" always; Apache: Header always set Referrer-Policy "strict-origin-when-cross-origin" Alternatives: no-referrer (most private), same-origin (no cross-origin referrer).
What is this?
HTTP cookies can carry security flags: HttpOnly (prevents JavaScript from reading the cookie, blocking XSS-based session theft), Secure (transmits the cookie only over HTTPS, never plain HTTP), and SameSite (controls cross-site submission, blocking CSRF attacks).
Why does it matter?
Without HttpOnly, malicious scripts injected via XSS can steal session cookies. Without Secure, cookies can leak over HTTP redirects or mixed-content requests. Without SameSite, cookies are sent with cross-site requests, enabling CSRF attacks that make users perform actions without their knowledge.
How to fix it
Add all three flags when setting cookies: Set-Cookie: session=abc123; HttpOnly; Secure; SameSite=Lax PHP: session_set_cookie_params([ 'httponly' => true, 'secure' => true, 'samesite' => 'Lax', ]); Laravel: in config/session.php set: 'http_only' => true, 'secure' => true, 'same_site' => 'lax', Use SameSite=Lax for most sites. Use SameSite=Strict if cross-site links to your site don't need to carry the session.

What is this?
DKIM (DomainKeys Identified Mail) adds a cryptographic signature to every outgoing email. The signature is created with a private key on your mail server and verified by recipients using a public key published in DNS.
Why does it matter?
DKIM proves that an email actually came from your mail server and was not modified in transit. Without DKIM, anyone can send emails that appear to be from your domain (spoofing), and DMARC alignment checks will fail even if SPF passes.
How to fix it
DKIM is configured in your email provider, not directly in DNS. Here is the process: 1. Generate a DKIM key pair in your email provider: - Google Workspace: Admin console → Apps → Gmail → Authenticate email - Microsoft 365: Admin center → Settings → Domains → DKIM - Mailchimp/SendGrid/Mailjet: Each has a DKIM setup page in their dashboard 2. Copy the TXT record they provide and add it to your DNS: Name: selector._domainkey.yourdomain.com Value: v=DKIM1; k=rsa; p=MIGf... 3. Activate DKIM signing in your provider after publishing the DNS record. The selector name (e.g. 'google', 'selector1') comes from your email provider.
What is this?
MTA-STS (Mail Transfer Agent Strict Transport Security) is a standard that forces other mail servers to use encrypted TLS connections when delivering email to your domain. Without it, a network attacker could silently strip TLS from email in transit.
Why does it matter?
Email is delivered between servers using SMTP. By default, SMTP tries TLS but falls back to plaintext if TLS is not available — a downgrade attack. MTA-STS prevents this fallback, ensuring all email delivered to your domain is encrypted in transit.
How to fix it
Implementing MTA-STS requires two things: 1. A DNS TXT record at _mta-sts.yourdomain.com: v=STSv1; id=20240101001 2. A policy file hosted at: https://mta-sts.yourdomain.com/.well-known/mta-sts.txt Policy file content: version: STSv1 mode: enforce mx: mail.yourdomain.com max_age: 86400 Start with mode: testing to see reports before enforcing. Use mta-sts.io for a guided setup.
