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

6 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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"

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 flexible and customizable online booking platform with a broad target audience spanning multiple industries. Its competitive advantage lies in its extensive feature set, multi-language support, and integration capabilities. The freemium business model allows easy adoption with upsell opportunities to paid plans. The company leverages partnerships with major payment processors and communication platforms to enhance service offerings. Growth indicators include a large customer base and positive user reviews on multiple platforms. The affiliate and reseller programs suggest an active partner ecosystem supporting market expansion.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible vulnerabilities or exposed sensitive information. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, the absence of a dedicated security policy page and incident response contacts limits transparency and readiness perception. No security.txt or vulnerability disclosure program is evident, which could hinder responsible vulnerability reporting. Overall, the security maturity is good but could benefit from enhanced documentation and communication of security practices.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and practices.
  2. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Enhance transparency by listing the Data Protection Officer contact details.
  5. Regularly review and audit third-party scripts and integrations for security risks.

Technical notes

Notes

The website is built on a custom or proprietary platform with no CMS detected, leveraging modern JavaScript and asynchronous loading of analytics and tracking scripts. It integrates with multiple third-party services for payments, calendar synchronization, and communications, indicating a modular and extensible architecture. Performance is optimized with lazy loading of images and videos, and mobile responsiveness is excellent. SEO is well addressed with proper meta tags and structured data (JSON-LD). Technical risks include reliance on multiple external scripts which require ongoing security monitoring. Overall, the technical infrastructure supports a scalable and user-friendly booking platform.
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.
