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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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 operates in the technology sector, providing flexible online booking software primarily targeting small to medium-sized businesses across diverse industries such as healthcare, education, fitness, and professional services. Their SaaS business model includes a free tier and scalable paid plans based on usage. The company leverages partnerships with major payment processors and communication platforms to enhance service offerings. The multilingual approach and extensive integrations indicate a global market strategy. The presence of affiliate and reseller programs suggests a broad partner ecosystem. The company’s longevity since 2007 and consistent branding reinforce its credibility and market stability.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and secure integration of payment gateways. No sensitive data leakage or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and explicit incident response contact channels limits transparency. There is no evidence of a vulnerability disclosure program or security.txt file. Privacy policies and cookie consent mechanisms align with GDPR requirements, indicating good data protection practices. Recommendations include publishing detailed security policies, establishing clear incident response contacts, and implementing a vulnerability disclosure framework to enhance security culture and trust.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and controls.
  2. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program, including a security.txt file.
  4. Enhance transparency on data retention and processing practices in privacy documentation.
  5. Conduct regular security audits of third-party integrations and update dependencies promptly.

The website is built with modern web technologies including JavaScript and integrates Google Tag Manager and Google Analytics for tracking. Payment integrations with PayPal, Stripe, and Mercado Pago are implemented securely. The site is mobile-optimized with responsive design and good accessibility features. Performance is fast with efficient loading of images and scripts. The CMS or platform is custom or not explicitly identified. The site uses structured data (JSON-LD) for SEO and rich snippets. There is no indication of technical debt or deprecated technologies. Opportunities exist to improve technical documentation and security transparency.
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.
