0–100, higher is better. How it is calculated

INTEC GMK is a specialized manufacturer and turnkey supplier of Organic Rankine Cycle (ORC) power plants designed to generate electricity from waste heat, geothermal energy, and biomass. The company positions itself as an innovative leader with the broadest range of ORC products, targeting industrial and energy sector clients. Their business model focuses on custom-made, highly individual solutions that integrate seamlessly into client processes, supporting the ongoing energy transition with sustainable power generation technologies. The website reflects a professional and consistent brand image with clear contact information and participation in industry exhibitions, reinforcing market credibility. Technically, the website is built using modern JavaScript frameworks such as Nuxt.js and Vue.js, likely managed via the Wagtail CMS. The site demonstrates good mobile optimization, clear navigation, and moderate performance. SEO practices are adequately implemented with proper meta tags and canonical URLs. However, some technical improvements could enhance security and privacy compliance, such as implementing cookie consent mechanisms and security headers. From a security perspective, the site uses HTTPS and does not expose sensitive data. However, no explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are publicly available. The absence of security headers and cookie consent banners indicates room for improvement in security posture and GDPR compliance. The WHOIS data is unavailable due to a malformed response, suggesting privacy protection, which is reasonable for this business type. Overall, the domain appears legitimate and consistent with the website's claims. The overall risk assessment is moderate with no critical vulnerabilities detected. Strategic recommendations include enhancing security headers, publishing incident response and vulnerability disclosure policies, and implementing cookie consent to improve privacy compliance and user trust. These steps will strengthen the company's digital maturity and security culture, supporting its professional market presence.

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

7 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.

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

INTEC GMK operates in the energy sector, focusing on ORC power plants for converting low-temperature heat sources into electrical energy. Their competitive advantage lies in offering the broadest range of ORC products and custom solutions tailored to client processes. The business model is B2B, targeting industrial clients requiring sustainable and cost-effective power generation. Revenue streams likely include product sales, turnkey project implementation, and ongoing service contracts. The company actively participates in industry exhibitions, indicating growth orientation and market engagement. The partnership with funkhaus.io for website development suggests a professional digital ecosystem. The company maintains a clear contact channel and consistent branding, supporting customer trust and operational transparency.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is used, ensuring encrypted communications. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No public security or incident response policies are found, and there is no vulnerability disclosure or security.txt file, limiting transparency and readiness for security incidents. Cookie consent mechanisms are missing, which may impact GDPR compliance. No exposed sensitive data or vulnerable libraries are detected in the provided content. Overall, the security posture is adequate but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish clear security policies and incident response procedures on the website to improve transparency and preparedness.
  3. Add a cookie consent banner/mechanism to comply with GDPR and enhance user privacy controls.
  4. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  5. Conduct regular security audits of third-party scripts and dependencies to prevent introduction of vulnerabilities.

Technical notes

Notes

The website is built on a modern JavaScript stack using Nuxt.js and Vue.js frameworks, providing server-side rendering and good SEO capabilities. The CMS appears to be Wagtail, indicated by API endpoints. The site loads multiple preloaded scripts and stylesheets, suggesting a modular and component-based architecture. Performance is moderate with good mobile optimization and accessibility at a basic level. SEO is well addressed with meta tags and canonical URLs. However, no explicit hosting provider information is available. The technical infrastructure supports a professional and scalable web presence but could benefit from enhanced security configurations and privacy features.
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.
