Risk levelMedium

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

ALUMERO Group is a European manufacturer and developer of photovoltaic mounting systems and innovative solar products, emphasizing sustainability through the use of recycled aluminium and local European production. The company targets businesses and professionals in the solar energy sector, offering a range of mounting solutions for various roof types and custom manufacturing services. Their market position is strengthened by their focus on supply chain control and environmental responsibility. Technically, the website is built on Webflow with modern integrations such as Google Tag Manager, Cookiebot for consent management, and Cloudflare Turnstile for bot protection, indicating a mature digital infrastructure. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms, though explicit security policies and incident response information are not published. Overall, the website is professional, well-designed, and compliant with GDPR, but could improve transparency by publishing terms of service and security policies. The domain WHOIS data is privacy protected, which is common and justified for this business type, with no suspicious indicators found.

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

2 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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

ALUMERO operates in the renewable energy sector, focusing on photovoltaic mounting systems made from sustainable recycled aluminium. Their business model involves manufacturing, product development, and distribution primarily within Europe, leveraging short supply chains to ensure reliability and sustainability. The company supports its partners with sales materials and training, indicating a strong partner ecosystem. The website content and structure suggest a medium-sized enterprise with a clear focus on B2B customers in the solar installation industry. Their metagreen sustainability concept is a key differentiator, aligning with increasing regulatory and market demands for environmentally responsible products. The presence of a dedicated partner program and product login portal indicates a mature business operation with ongoing customer engagement and support.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, modern security headers, and integration of Cookiebot for GDPR-compliant cookie consent management. The use of Cloudflare Turnstile adds bot protection, enhancing security against automated threats. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency and may impact trust for security-conscious stakeholders. No vulnerabilities or exposed sensitive data were detected in the content. The website could benefit from publishing a security.txt file and providing clear contact channels for security incidents to improve incident response readiness and compliance with best practices.

Recommendations

  1. Publish a clear security policy and incident response information on the website to enhance transparency and trust.
  2. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Provide explicit company contact information including emails and phone numbers for customer and security inquiries.
  4. Develop and publish terms of service to clarify legal conditions of website and product use.
  5. Enhance accessibility features to improve compliance with accessibility standards and broaden user inclusivity.

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.
