Full report
DNS & Email Security
75/100SPF record configured
SPF record found: "v=spf1 a mx ip4:2.58.165.67 a:vboxxcloud.nl include:_spf.vboxx.nl -all".
DMARC record configured
DMARC record found with policy "reject": "v=DMARC1;p=reject".
CAA record configured
No CAA record found. Any Certificate Authority can issue SSL certs for your domain.
Fix: Add a CAA DNS record, e.g.: 0 issue "letsencrypt.org" to restrict SSL issuance.
DKIM record configured
DKIM record found (selector "mail") — outgoing emails are cryptographically signed.
MTA-STS (email transport security)
No MTA-STS record found at _mta-sts.vboxxcloud.nl. 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.vboxxcloud.nl with value "v=STSv1; id=YYYYMMDD01" and publish a policy file at https://mta-sts.vboxxcloud.nl/.well-known/mta-sts.txt
IPv6 support
No AAAA record found. The domain is IPv4-only.
Fix: Add an AAAA record to support IPv6. Most modern hosting providers and CDNs assign IPv6 addresses automatically.
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.vboxxcloud.nl: 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 expires soon: 2026-05-11 (30 days left).
Fix: Renew your SSL certificate before it expires.
HTTP redirects to HTTPS
HTTP traffic is permanently (301) redirected 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
88/100No 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)
1 of 1 external script(s)/stylesheet(s) load without an integrity= hash. If the CDN is compromised, malicious code could be silently injected into your pages.
Fix: Add integrity= and crossorigin= attributes to external <script> and <link> tags. Generate hashes at https://www.srihash.org/
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
100/100Server version not disclosed
The Server header does not expose version information.
Content-Security-Policy
CSP header enforced: "upgrade-insecure-requests;"
X-Frame-Options
X-Frame-Options: SAMEORIGIN — protects against clickjacking.
X-Content-Type-Options
X-Content-Type-Options: nosniff is set — prevents MIME-type sniffing.
Referrer-Policy
Referrer-Policy: strict-origin-when-cross-origin
Permissions-Policy
Permissions-Policy header found — browser feature access is restricted.
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.
X-XSS-Protection (deprecated)
X-XSS-Protection: 1; mode=block — Note: this header is deprecated and ignored by modern browsers. Rely on CSP instead.
Performance & SEO
100/100Fast server response time (TTFB)
Time To First Byte: 37 ms (measured from our scanner server) — excellent.
Response compression enabled
Compression is enabled (gzip) — 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.
Warnings (5)
What is this?
CAA (Certification Authority Authorization) is a DNS record that specifies which Certificate Authorities (CAs) are allowed to issue SSL/TLS certificates for your domain.
Why does it matter?
Without CAA records, any of the hundreds of trusted CAs worldwide can issue a certificate for your domain. A compromised or rogue CA could issue a fraudulent certificate for your domain, enabling MITM attacks. CAA limits this risk to your chosen CA(s).
How to fix it
Add CAA records to your DNS. Example for Let\'s Encrypt only: 0 issue "letsencrypt.org" For multiple CAs (e.g. Let\'s Encrypt + DigiCert): 0 issue "letsencrypt.org" 0 issue "digicert.com" To also allow wildcard certificates: 0 issuewild "letsencrypt.org" For email notifications on unauthorized issuance attempts: 0 iodef "mailto:security@yourdomain.com" Check current CAA records at: sslmate.com/caa
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.
What is this?
An SSL/TLS certificate has an expiry date. Once expired, browsers show a full-page warning to visitors and refuse to connect without clicking through a security warning.
Why does it matter?
An expired certificate breaks trust immediately — visitors see a red warning screen and most will leave. Search engines may also de-index or lower the ranking of sites with certificate errors.
How to fix it
Renew your certificate before it expires. If you use Let's Encrypt, set up auto-renewal with certbot (sudo certbot renew --dry-run to test). Most hosting providers send expiry warnings by email. Set a calendar reminder at 30 and 7 days before expiry.
What is this?
Subresource Integrity (SRI) is a browser security feature that lets you specify a cryptographic hash for external scripts and stylesheets. The browser refuses to execute the resource if its content does not match the hash.
Why does it matter?
If a CDN you rely on is compromised (a real and recurring attack vector), an attacker can replace your JavaScript library with malicious code that steals user data, injects cryptomining scripts, or performs other attacks. SRI prevents this by making the browser verify the file has not been altered.
How to fix it
Add integrity= and crossorigin= attributes to your external resources: <script src="https://cdn.jsdelivr.net/npm/jquery@3.7.1/dist/jquery.min.js" integrity="sha256-/JqT3SQfawRcv/BIHPThkBvs0OEvtFFmqPF/lYI/Cxo=" crossorigin="anonymous" ></script> Generate hashes for any URL at: https://www.srihash.org/ For build tools, use webpack-subresource-integrity or vite-plugin-sri to add hashes automatically during builds.
