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. 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

    • 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

  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 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

The organization targets businesses and individuals seeking high-quality sign services, leveraging a certification program to differentiate professional sign companies. The platform supports growth through education and sustainability initiatives, enhancing industry reputation. The extensive member directory and partner ecosystem indicate a broad network and market reach. The business benefits from a long domain history and consistent branding, positioning it as a leader in the regional sign industry.

Security posture

The website demonstrates good security fundamentals including HTTPS, DNSSEC, and secure form handling. However, it lacks explicit security headers and a public vulnerability disclosure policy. No incident response contacts or data protection officer information is provided, which are areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is strong but could be enhanced by adopting additional best practices and compliance transparency.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  4. Provide clear incident response contact information including security or abuse email addresses.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern WordPress CMS with popular plugins like Yoast SEO and WP Rocket for SEO and performance optimization. It integrates Google Fonts, FontAwesome icons, Google Maps API, and a swiper carousel for partner logos. The site is mobile responsive and well-structured with semantic HTML and JSON-LD structured data for SEO. Performance is moderate with caching enabled but could benefit from further optimization. Accessibility is basic but functional. No major technical debt or risks were identified.
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.
