Interargem GmbH operates as a regional energy company specializing in environmentally responsible waste-to-energy solutions through its modern waste incineration plants in Bielefeld and Hameln, Germany. The company focuses on converting regional waste into electricity and district heating, contributing significantly to environmental and climate protection efforts. Their market position is that of a trusted regional leader providing essential waste management and energy services to local businesses, households, and public institutions. Technically, the website is built on a WordPress CMS platform enhanced with Yoast SEO for search optimization and Consentmanager for GDPR-compliant cookie management. The site demonstrates good mobile optimization and a professional design, although some accessibility features could be improved. Performance is moderate, with no critical technical issues detected. From a security perspective, the site enforces HTTPS and employs a cookie consent mechanism, but lacks advanced security headers and published security policies or incident response contacts. No vulnerabilities or suspicious content were found, indicating a generally sound security posture, though improvements are recommended to enhance protection and transparency.

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

5 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 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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. 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

  • 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

Interargem GmbH holds a strong regional market position in the energy sector, specifically in waste-to-energy conversion. Their business model leverages thermal waste treatment and combined heat and power generation to provide sustainable energy solutions. The company targets regional waste suppliers, local businesses, and public institutions, ensuring reliable waste disposal and energy supply. Their operations include two main subsidiaries, MVA Bielefeld and Enertec Hameln, which handle significant volumes of municipal and industrial waste annually. The company demonstrates growth potential through its environmental focus and regional partnerships, supported by a clear and consistent brand presence online.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and GDPR-compliant cookie consent mechanisms in place. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security, as well as the lack of published security policies or incident response contacts, indicates gaps in security best practices. No exposed sensitive data or vulnerable libraries were detected, and no signs of malware or phishing were found. The company would benefit from formalizing its security posture through documented policies and enhanced technical controls to mitigate potential risks and improve stakeholder trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website against common attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and readiness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and plugins to minimize vulnerabilities.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS version 6.8.1, utilizing Yoast SEO plugin for search engine optimization and Consentmanager for cookie consent management. It employs jQuery libraries and custom JavaScript for UI interactions such as sliders and date pickers. The site loads external scripts from consentmanager.net and WordPress core domains. The design is responsive and optimized for mobile devices, with moderate performance. No hosting provider details were explicitly found, but DNS name servers indicate hosting aligned with the regional business area. The site uses valid meta tags and structured data (JSON-LD) for SEO and rich snippets. Opportunities exist to modernize security headers and improve accessibility compliance.
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.
