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

11 findings rated critical or high. Fix these first.

  1. Network security

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

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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

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 · found on this site
  • 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

sisKMR.com operates in the energy sector, focusing on software for district heating pipeline design and analysis. The business model centers on software licensing combined with engineering services and training. The company targets professional engineers and planners, leveraging a long-standing reputation and compliance with key European and international standards (EN13941, EN13480, AGFW FW 401, ASME). The website supports multilingual access, indicating an international customer base. The presence of a newsletter and contact forms suggests active customer engagement. No direct e-commerce or payment processing is evident. The company appears small-sized but well-established, with a clear parent company (GEF Ingenieur AG) and no subsidiaries listed. The partnership ecosystem is limited but includes recognized industry standards and newsletter service providers.

Security posture

The website enforces HTTPS and has domain transfer protection, which are positive security indicators. However, DNSSEC is not enabled, which is a recommended best practice for domain security. No security headers such as Content Security Policy or HSTS were detected, representing an area for improvement. The site uses WordPress with common plugins, which requires regular updates to avoid vulnerabilities. No exposed sensitive data or known vulnerabilities were found in the analysis. Privacy policy is comprehensive and GDPR compliant, but no explicit incident response or security policy is published. Contact forms are present and appear secure, but no advanced security measures like CAPTCHA or multi-factor authentication are evident. Overall, the security posture is moderate with room for enhancement in domain and web application security.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner and explicit cookie policy to comply fully with privacy regulations.
  4. Publish a dedicated security policy and incident response information to improve transparency and trust.
  5. Regularly audit and update WordPress core, themes, and plugins to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using the OnePress theme and several plugins including Stackable Ultimate Gutenberg Blocks and CoBlocks. It uses jQuery and Bootstrap for frontend functionality and styling. The site is multilingual with German as primary language and English and French alternatives. Hosting details are not explicitly stated but DNS servers suggest a European hosting provider. Performance is moderate with some parallax and animation effects. Mobile optimization is good with responsive design. SEO is supported by proper meta tags and alternate hreflang links. Accessibility is basic but present. No advanced analytics or tracking scripts were detected beyond newsletter integration. The site uses HTTPS with a valid certificate. Overall, the technical implementation is solid but could benefit from enhanced security headers and performance optimizations.
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.
