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. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

  • Security headers: did not complete in this scan.
  • 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 significant regional player in the energy and building services sector, offering comprehensive technical planning and execution services. Its business model focuses on providing specialized services in sanitary, heating, ventilation, and electrical trades, supported by a stable workforce and multiple locations. The website emphasizes employee benefits and company values, indicating a strong employer branding strategy to attract talent. Revenue streams likely derive from project execution and technical planning services. The absence of explicit contact details on the homepage suggests a focus on controlled communication channels, possibly centralized through internal HR or contact pages. The use of GDPR-compliant tools and cookie consent reflects awareness of regulatory requirements. The company does not publicly display certifications or security policies, which could be areas for future enhancement.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no signs of exposed sensitive information or vulnerable libraries. The presence of cookie consent and privacy policy indicates compliance with data protection regulations. However, the lack of visible security headers such as Content Security Policy, X-Frame-Options, or HSTS suggests room for improvement in hardening the site against common web attacks. No incident response or vulnerability disclosure information is provided, which could limit transparency in security management. The integration of third-party scripts like OneSignal and Google Analytics is standard but requires ongoing monitoring to mitigate supply chain risks. Overall, the site is secure for typical business operations but would benefit from enhanced security headers and published security policies.

Recommendations

  1. Implement HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen defense against web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update all WordPress plugins and core to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider adding visible contact information on the homepage or a dedicated contact page to facilitate communication.

Technical notes

Notes

The website is built on a modern WordPress CMS platform, utilizing popular plugins such as Revolution Slider for dynamic content and OneSignal for push notifications. It employs Google Tag Manager and Google Analytics for tracking and marketing analytics. The hosting provider is webgo.de, indicated by the nameservers. The site is responsive and optimized for mobile devices with good SEO meta tags and Open Graph data for social sharing. Performance is moderate, with some heavy slider content and video backgrounds that may impact load times. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. The technical stack is standard for a professional corporate site, with opportunities to optimize performance and security further.
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.
