Risk levelLow

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

hollomet GmbH is a specialized German company providing innovative cellular materials made from metallic and ceramic substances, focusing on sectors such as heat management, process technology, lightweight construction, energy absorption, and design. The company positions itself as a competent development and manufacturing partner offering tailored solutions for industrial clients, particularly in automotive and machinery sectors. The website is professionally designed, multilingual, and optimized for SEO, reflecting a mature digital presence. Security posture is good with HTTPS and cookie consent mechanisms, though some security headers are missing and media content has minor loading issues. WHOIS data is unavailable or indicates a very new domain, which slightly reduces trust but does not contradict the professional business presentation. Overall, the site is trustworthy, GDPR compliant, and business credible.

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

1 finding 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.

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

The company operates in the manufacturing and energy sectors, targeting industrial clients requiring advanced materials for lightweight and efficient applications. Their business model is B2B, focusing on innovation and custom product development. The partnership with glatt.com suggests a strong ecosystem in material processing. The website content and structured data indicate a small-sized company with a clear market niche and growth potential. The absence of detailed WHOIS data warrants monitoring but does not currently undermine the business credibility. The company leverages modern web technologies and SEO tools to maintain visibility and engagement.

Security posture

The website employs HTTPS and a cookie consent mechanism compliant with GDPR, indicating a baseline security and privacy awareness. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to certain web-based attacks. No incident response or vulnerability disclosure information is provided, which is a missed opportunity for transparency and preparedness. Media loading errors could affect user experience and potentially indicate content management issues. Overall, the security posture is moderate with room for improvement in headers and incident readiness.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Fix broken or inaccessible media files to improve user experience and reduce potential security concerns.
  3. Add a security.txt file and clearly publish incident response contact information to improve transparency and readiness.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Consider publishing terms of service and data protection officer contact details to strengthen compliance and trust.

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.
