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.

Priority findings

4 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. 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

Hammerwerk Erft operates in the manufacturing sector, focusing on forging technology for industrial applications. The company leverages decades of experience to serve a B2B market with complex and customized metal components. Their competitive advantage lies in their comprehensive manufacturing competence from raw forging to finished products, ensuring high quality and technical excellence. The website's social media presence and detailed product portfolio suggest active engagement with clients and stakeholders. Hosting with a German provider aligns with their geographic focus. The absence of detailed WHOIS registrant data limits full verification but does not raise immediate concerns. The business model is straightforward manufacturing supply, with potential growth through digital presence and enhanced compliance.

Security posture

The website demonstrates basic security maturity with HTTPS usage and a cookie consent mechanism. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerability disclosures or incident response contacts are published, which could hinder rapid response to security incidents. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site lacks a published privacy policy, which is a compliance gap under GDPR. Overall, the security posture is moderate but could be significantly improved by implementing standard security headers, publishing security policies, and establishing incident response channels.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  2. Implement and configure security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Add explicit incident response contact channels, such as security@ or abuse@ email addresses.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design and Swiper.js for interactive sliders. SVG graphics are used for logos and icons, enhancing visual quality. Cookie consent is managed by Klaro, indicating attention to privacy compliance. Hosting is provided by kundenserver.de, a German hosting provider, consistent with the company's location. Performance appears moderate with optimized images and structured content. Accessibility features are basic but present. SEO optimization is good with proper meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or static site. Technical risks include lack of security headers and incomplete privacy disclosures.
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.
