This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

SuperSaaS holds a strong market position as a versatile online booking system provider, catering to diverse industries including healthcare, education, wellness, and public services. Its business model is subscription-based with a free tier, supported by integrations with major payment processors like PayPal and Stripe. The platform's competitive advantage lies in its flexibility, extensive feature set, and global reach with multi-language support. The company maintains active social media engagement and a comprehensive support and documentation ecosystem, fostering customer trust and retention.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, cookie consent mechanisms, and no visible exposure of sensitive data. While explicit security policies and incident response contacts are not published, the use of modern web technologies and AWS hosting suggests a baseline of security best practices. No vulnerabilities or suspicious patterns were detected in the content or WHOIS data. Recommendations include publishing a dedicated security policy and vulnerability disclosure framework to enhance transparency and trust.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and controls.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  3. Provide explicit contact information for security incidents and abuse reporting.
  4. Verify and document HTTP security headers to strengthen protection against common web attacks.
  5. Regularly audit third-party scripts and integrations to mitigate supply chain risks.

Hosting on AWS infrastructure ensures scalability and reliability. The site is mobile-responsive and accessible, with SEO best practices evident in meta tags and structured data (JSON-LD). Use of Google Tag Manager and Analytics supports data-driven insights while respecting privacy compliance. No CMS detected, suggesting a custom or proprietary platform. Overall, the technical implementation supports a fast, secure, and user-friendly experience.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
