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

2 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 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. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 government and technology sectors, providing web agency services with a focus on accessibility and eGovernment solutions. Their business model revolves around delivering tailored CMS and digital services to Swiss public institutions and SMEs. The presence of client testimonials and structured data enhances trust and credibility. The company appears small-sized but well-positioned within its niche market. The lack of explicit privacy and terms pages suggests potential compliance gaps. No affiliate or advertising networks are detected, indicating a direct service model without third-party marketing dependencies.

Security posture

The website uses HTTPS and modern libraries, with cookie consent mechanisms in place, reflecting a baseline security maturity. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the overall security hardening. No vulnerability disclosures or incident response contacts are published, which could impact incident handling readiness. No exposed sensitive data or vulnerable libraries were detected in the analysis. Security score is good but could be improved by adding formal policies and headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and enforce security headers like CSP, HSTS, and X-Frame-Options to enhance security posture.
  3. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide clear incident response contact information to improve security incident management.
  5. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a custom CMS platform with integration of modern JavaScript libraries such as jQuery, Font Awesome 7 Pro, Swiper, and accessibility tools like a11y-dialog. The site is mobile optimized with good accessibility features including skip links and ARIA labels. Performance is moderate, with some heavy images but responsive design techniques applied. SEO is supported by meta tags, Open Graph, and JSON-LD structured data. The hosting provider is not explicitly identified. The site uses cookie consent scripts indicating GDPR awareness. There is room for improvement in security headers and privacy documentation to reduce technical risks.
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.
