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

3 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

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

    • 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

  3. 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 positions itself as a key IT partner for Swiss enterprises across multiple sectors, emphasizing end-to-end consulting and managed services. Their business model focuses on leveraging technology to optimize core business processes, supported by a broad partner network and certifications like ISO 27001. The presence of detailed success stories and sector-specific competencies indicates a strategic approach to market segmentation and client engagement. The company’s digital maturity is evidenced by the use of advanced analytics and privacy-compliant tracking, supporting data-driven decision-making and marketing. Their social media integration and transparent contact information further enhance their market credibility and customer reach.

Security posture

The website exhibits a solid security foundation with HTTPS, security headers, and privacy-compliant cookie management. However, the absence of a publicly available security policy, incident response plan, or vulnerability disclosure program suggests areas for improvement in transparency and proactive security communication. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable analytics and tracking services with consent mechanisms aligns with GDPR requirements. Strengthening incident response visibility and publishing a security.txt file would enhance trust and preparedness.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Implement and publicize an incident response plan with clear contact channels for security issues.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Consider appointing and publishing Data Protection Officer contact details to reinforce GDPR compliance.
  5. Maintain and regularly update privacy and cookie policies to reflect evolving regulations and technologies.

Technical notes

Notes

The website uses a modern tech stack including Web Components, FontAwesome icons, and Piwik PRO for analytics, ensuring a contemporary and modular front-end architecture. The site is mobile-optimized with responsive design and accessibility features, contributing to a positive user experience. Performance is moderate, with preloading of fonts and asynchronous loading of scripts. The absence of a known CMS suggests a custom or proprietary content management solution, which may require dedicated maintenance resources. Overall, the technical implementation supports the business goals effectively but could benefit from performance tuning and enhanced 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.
