Full report
DNS & Email Security
0/100SPF record configured
No SPF record found. Anyone can send emails pretending to be from your domain.
Fix: Add a TXT record to your DNS: v=spf1 include:yourmailprovider.com ~all
DMARC record configured
No DMARC record found at _dmarc.gip.ucp.pt.
Fix: Add a TXT record to _dmarc.gip.ucp.pt: v=DMARC1; p=quarantine; rua=mailto:dmarc@gip.ucp.pt
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
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.gip.ucp.pt
MTA-STS (email transport security)
No MTA-STS record found at _mta-sts.gip.ucp.pt. 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.gip.ucp.pt with value "v=STSv1; id=YYYYMMDD01" and publish a policy file at https://mta-sts.gip.ucp.pt/.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.gip.ucp.pt: 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 2026-11-25 (229 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.
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
83/100Server version not disclosed
The Server header does not expose version information.
Content-Security-Policy
CSP is set but weakened by 'unsafe-inline' and 'unsafe-eval' in default-src. These directives allow inline scripts and effectively disable XSS injection protection.
Fix: Remove 'unsafe-inline' and 'unsafe-eval' from your CSP. Replace inline scripts with external files or use nonces/hashes. Test your policy at https://csp-evaluator.withgoogle.com/
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: no-referrer
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
50/100Fast server response time (TTFB)
Time To First Byte: 241 ms (measured from our scanner server) — excellent.
Response compression enabled
No gzip or Brotli compression detected.
Fix: Enable gzip or Brotli compression on your web server. This typically reduces HTML/CSS/JS size by 60-80%.
robots.txt present
A robots.txt file was found and is accessible.
XML sitemap present
No sitemap.xml found at common locations (/sitemap.xml, /sitemap_index.xml).
Fix: Create and submit an XML sitemap to Google Search Console to improve search indexing.
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?
Sender Policy Framework (SPF) is a DNS TXT record that specifies which mail servers are authorised to send email on behalf of your domain.
Why does it matter?
Without SPF, anyone can send emails that appear to come from your domain (email spoofing). This is used in phishing attacks to impersonate your business. SPF tells receiving mail servers which IPs are legitimate senders.
How to fix it
Add a TXT record to your domain\'s DNS: Host: @ (apex domain) Value: v=spf1 include:_spf.yourmailprovider.com ~all Examples: Google Workspace: v=spf1 include:_spf.google.com ~all Microsoft 365: v=spf1 include:spf.protection.outlook.com ~all Mailchimp: v=spf1 include:servers.mcsv.net ~all Use ~all (softfail) to start, upgrade to -all (hard fail) once you're confident all sending sources are listed. Never use +all.
What is this?
DMARC (Domain-based Message Authentication, Reporting & Conformance) builds on SPF and DKIM to give domain owners control over what happens to emails that fail authentication checks.
Why does it matter?
SPF alone is not enough — DMARC adds a policy layer that tells receiving servers what to do with suspicious emails (monitor, quarantine, or reject). It also provides reporting so you can see who is sending email as your domain.
How to fix it
Add a TXT record to your DNS: Host: _dmarc (e.g. _dmarc.yourdomain.com) Value: v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com Start with p=none to receive reports without affecting mail delivery: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com After analysing reports for a few weeks, upgrade to: p=quarantine → suspicious mail goes to spam p=reject → suspicious mail is blocked entirely Free DMARC report analysis: dmarcian.com, postmarkapp.com/dmarc.
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?
Response compression (gzip or Brotli) reduces the size of HTML, CSS, JavaScript and other text-based responses before sending them over the network.
Why does it matter?
Compression typically reduces text file sizes by 60–80%. A 200 KB JavaScript file becomes ~50 KB. This directly reduces page load time, especially on slower connections, and reduces bandwidth costs.
How to fix it
Nginx: gzip on; gzip_types text/plain text/css application/javascript application/json; gzip_min_length 1000; For Brotli (better compression, requires ngx_brotli module): brotli on; brotli_types text/plain text/css application/javascript; Apache (.htaccess): AddOutputFilterByType DEFLATE text/html text/css application/javascript Cloudflare: enables compression automatically — no server config needed.
Warnings (6)
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?
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.
What is this?
Content Security Policy (CSP) is a browser security feature that lets you control which resources (scripts, styles, images, fonts) a page is allowed to load, and from which origins.
Why does it matter?
CSP is one of the most effective defences against Cross-Site Scripting (XSS) attacks. Without CSP, an attacker who injects malicious JavaScript into your page can load resources from anywhere, steal session cookies, or redirect users.
How to fix it
Add a Content-Security-Policy header. Start with a report-only policy to detect issues without breaking anything: Content-Security-Policy-Report-Only: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; Once tested, switch to enforcing: Content-Security-Policy: default-src 'self'; ... CSP policies can be complex for sites with third-party scripts. Use https://csp-evaluator.withgoogle.com/ to evaluate your policy.
What is this?
An XML sitemap is a file that lists all the important URLs on your website, helping search engines discover and index your pages more efficiently.
Why does it matter?
Search engines may miss pages that are not linked from anywhere (orphan pages) or pages deep in your site structure. A sitemap ensures they are found and indexed. It also allows you to signal content priority and update frequency.
How to fix it
Create an XML sitemap at https://yourdomain.com/sitemap.xml WordPress: install Yoast SEO or use the built-in sitemap at /wp-sitemap.xml Laravel: use spatie/laravel-sitemap package Static sites: generate with a sitemap generator tool After creating your sitemap, submit it to: - Google Search Console: search.google.com/search-console - Bing Webmaster Tools: bing.com/webmasters Also reference it in your robots.txt: Sitemap: https://yourdomain.com/sitemap.xml
