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

AGFW is a German industry association specializing in standardizing minimum requirements across the heat and cold supply sector. The website serves as a professional portal providing access to technical rulebooks and regulatory documents primarily for members and subscribers. The organization positions itself as a key standard-setter in the energy sector, supporting operational companies with up-to-date technical guidelines. Technically, the site employs modern web technologies including Bootstrap, jQuery, and FontAwesome, with Google Analytics and Tag Manager integrated for analytics and marketing purposes. The site is hosted on servers associated with giordano-online.net and uses HTTPS with privacy-conscious configurations such as IP anonymization. Security posture is moderate with good practices like CSRF tokens and cookie consent, though lacking explicit security policies or incident response contacts. Overall, the website is professional, well-structured, and compliant with GDPR, targeting industry professionals and members. No blocking or WAF mechanisms were detected, and no adult or questionable content is present.

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

3 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 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. 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

AGFW operates as an essential entity within the energy sector, focusing on heat and cold supply standardization. Its business model revolves around providing technical rulebooks and standards through paid subscriptions and a web shop. The target audience includes industry professionals, member companies, and subscribers requiring access to updated technical regulations. The organization maintains a consistent brand presence and leverages partnerships with related domains such as agfw.de and agfw-shop.de. The website content and structure indicate a medium-sized organization with a strong market position in Germany. The use of social media platforms like LinkedIn, Xing, Facebook, and YouTube supports community engagement and outreach. The absence of direct phone numbers or physical addresses on the site suggests a preference for digital contact channels.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced with anonymized IP tracking in analytics, and CSRF tokens protect login forms. Cookie consent mechanisms comply with GDPR requirements. However, the absence of security headers such as Content-Security-Policy and lack of published security policies or incident response contacts represent gaps. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from publishing a security policy, incident response contacts, and implementing additional HTTP security headers. Regular audits of third-party libraries and enhanced accessibility features would further strengthen security and compliance posture.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Conduct regular vulnerability assessments and update third-party libraries to mitigate risks.
  4. Enhance website accessibility to meet recognized standards and improve user experience.
  5. Consider adding a security.txt file or vulnerability disclosure policy to encourage responsible reporting.

Technical notes

Notes

The website uses a modern technology stack with Bootstrap for responsive design, jQuery for DOM manipulation, and FontAwesome for icons. Google Analytics and Tag Manager are integrated for analytics and marketing. Hosting is managed via giordano-online.net nameservers. The site loads moderately fast with good mobile optimization and clear navigation. The presence of CSRF tokens in forms indicates attention to security in user input handling. Cookie consent is managed by Legal Cockpit, ensuring compliance with privacy regulations. There is no detected CMS, suggesting a custom or static site architecture. Opportunities exist to improve accessibility and implement additional security headers to reduce technical risks.
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.
