The website ablesen.de represents co.met GmbH, a German company specializing in digital meter reading and consumption data management services. Their offering includes a full-service solution for meter data acquisition, customer self-reading, and support for various meter technologies such as OMS-Funk and LoRaWAN. The company targets energy providers and meter operators, positioning itself as a specialized service provider in the energy sector. The website content is professional, well-structured, and primarily in German, reflecting a focused business audience. Technically, the website is built with standard HTML5 and CSS3, hosted on servers associated with Stadtwerke Saarbrücken Konzern, indicating reliable local infrastructure. The site is moderately optimized for performance and mobile devices, with good SEO practices and basic accessibility features. No advanced frameworks or CMS platforms are detected, suggesting a lightweight and straightforward implementation. From a security perspective, the site uses HTTPS as indicated by canonical URLs, but lacks explicit security headers and a published security policy. The privacy policy is comprehensive and GDPR compliant, detailing data processing, retention, and user rights. No cookie consent mechanism or terms of service are found, which could be improved. No signs of WAF or blocking mechanisms are present, and no vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website demonstrates a solid business credibility and privacy compliance posture with room for improvement in security best practices and transparency. The risk level is low, but enhancing security headers, cookie management, and incident response information would strengthen trust and compliance.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  2. 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 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';…

  3. 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

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

co.met GmbH operates in the energy sector, providing digital meter reading and data acquisition services primarily to utility companies and meter operators. Their business model revolves around offering a full-service platform (co.read®) that enables customer self-reading and supports multiple meter technologies. The company appears to be a small-sized specialized service provider with a focused market niche in Germany. The website content and WHOIS data align well, indicating consistent business operations. The company maintains direct contact channels and a data protection officer, reflecting compliance with GDPR. No explicit revenue or growth data is available, but the partnership with Stadtwerke Saarbrücken Konzern for hosting suggests local industry integration. The absence of social media or extensive marketing tools indicates a possibly conservative or B2B-focused marketing approach.

Security posture

The website shows a moderate security maturity level. HTTPS is used, ensuring encrypted communication. The privacy policy is detailed and GDPR compliant, indicating good data protection awareness. However, the absence of explicit security headers (such as Content Security Policy, HSTS, X-Frame-Options) and lack of a published security policy or incident response plan are gaps. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. No tracking or analytics scripts were detected, reducing privacy risks. Overall, the security posture is adequate for a small B2B service site but could be improved by implementing recommended headers, cookie consent, and incident response disclosures.

Recommendations

  1. Implement HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie policy and consent mechanism to comply fully with privacy regulations and improve user transparency.
  3. Publish a formal security policy and incident response contact information to improve trust and preparedness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance accessibility features and conduct regular security audits to maintain and improve the security posture.

Technical notes

Notes

The website is built using standard HTML5 and CSS3 without detectable advanced frameworks or CMS platforms, indicating a simple and maintainable technical stack. Hosting is provided by Stadtwerke Saarbrücken Konzern, suggesting reliable German infrastructure. Performance is moderate with good mobile optimization and SEO practices. No external analytics or marketing scripts are present, reducing technical complexity and privacy concerns. The site lacks explicit security headers and cookie management, representing technical debt in security best practices. There are no detected forms or interactive elements on the main page, limiting attack surface but also user engagement features. Overall, the technical implementation is solid but could benefit from modernization in security and privacy tooling.
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.
