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

9 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

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

The company operates in the cleaning and facility services sector, targeting medium to large enterprises and institutions requiring hygienic and cleaning services. Its business model leverages substitute fulfillment to help companies meet legal employment quotas for persons with disabilities, providing a competitive advantage and social responsibility appeal. The presence of multiple sister companies under the TSC Group umbrella indicates a diversified service portfolio and strong market presence. The website's content and certifications reinforce credibility and trust, supporting growth and partnership opportunities.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and secure contact forms including reCaptcha. However, the absence of visible security headers and lack of explicit security or incident response policies indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. GDPR compliance is partially addressed via consent checkboxes and cookie policy references, but more explicit privacy and security documentation would enhance compliance and user trust.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish explicit privacy and security policies on the website to improve transparency and compliance.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern front-end stack including Google Tag Manager for analytics and tracking, Swiper.js for interactive carousels, and Bootstrap components for responsive design and modals. The site is mobile-optimized with good navigation and SEO meta tags. Performance is moderate with room for optimization. No CMS or hosting provider information was detected. The site uses reCaptcha v3 for form spam protection. Overall, the technical implementation supports a professional and user-friendly experience but could benefit from enhanced security configurations and performance tuning.
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.
