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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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';…

  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 ERNE Gruppe operates in the construction and real estate sectors in Switzerland, providing services in traditional and system construction as well as real estate management. The business model focuses on delivering innovative construction solutions and comprehensive service offerings. The company leverages partnerships with service providers such as Prospective Media Services AG for job listings and Typeform for forms and surveys. Marketing efforts include retargeting and tracking via major platforms like Google, Facebook, LinkedIn, and TikTok, indicating a mature digital marketing strategy. The website's content and structure support a professional image aimed at clients and partners in the Swiss market.

Security posture

The website exhibits a mature security posture with HTTPS enabled and use of Google reCAPTCHA to mitigate automated abuse. Cookie consent is managed via a comprehensive GDPR-compliant mechanism, ensuring user privacy and legal compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement in defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party scripts necessitates ongoing monitoring for vulnerabilities. Incident response and security policy documentation are not publicly available, which could be enhanced to improve transparency and readiness.

Recommendations

  1. Implement Content-Security-Policy header to mitigate cross-site scripting and related attacks.
  2. Add X-Frame-Options header to prevent clickjacking attacks.
  3. Add X-Content-Type-Options header to prevent MIME sniffing.
  4. Publish a security policy and incident response information to improve transparency and trust.
  5. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, combined with modern frontend libraries such as Bootstrap, jQuery, Swiper, and Parsley.js for validation. The site uses Google Tag Manager to manage analytics and marketing tags, including Google Analytics, Crazy Egg, and social media pixels. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and multilingual support. The technical infrastructure appears well-maintained, though some security headers are missing. Hosting provider details are not explicitly identified in the HTML content.
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.
