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

BTC Business Technology Consulting AG is a well-established IT service provider headquartered in Oldenburg, Germany, with a significant international presence including subsidiaries in Poland, Switzerland, and Turkey. The company specializes in IT consulting and digital transformation services targeting various sectors such as energy, public sector, and general business industries. Their offerings include sustainability services, human capital management, financial solutions, GIS services, and AI integration, positioning them as a comprehensive IT partner for enterprises and government entities. The website reflects a professional and consistent brand image, supporting their market position as a large, reputable technology company. Technically, the website employs modern JavaScript libraries such as jQuery, Owl Carousel, and AOS for animations, alongside Font Awesome for icons and Piwik PRO for analytics. The site is well-optimized for mobile devices, has good SEO practices, and includes comprehensive metadata and Open Graph tags. Performance is moderate, with no major technical debt or outdated technologies detected. The absence of a detected CMS suggests a custom or proprietary platform. From a security perspective, the site enforces HTTPS with strong SSL configuration and includes important security headers, indicating a solid security posture. However, there is no publicly visible security policy or incident response contact, which are areas for improvement. Privacy compliance is well addressed with a comprehensive privacy policy, cookie consent mechanisms, and GDPR adherence. The WHOIS data is missing or unavailable, which raises concerns about domain registration transparency but does not directly impact the operational security or professionalism of the site. Overall, BTC AG presents a trustworthy and professional digital presence with strong business credibility and technical implementation. The main risk lies in the lack of WHOIS transparency and absence of explicit security incident response information. Strategic recommendations include publishing a security policy, establishing a vulnerability disclosure program, and verifying domain registration details to enhance 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

3 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.

    • 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. 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

BTC AG operates in the IT consulting sector with a focus on digital transformation for diverse industries including energy and public sector. Their competitive advantage lies in their broad service portfolio, international footprint, and certifications such as ISO 27001. Revenue streams likely include consulting fees, software integration, and managed services. The target customers are medium to large enterprises and government organizations seeking IT modernization. Growth indicators include multiple international subsidiaries and a comprehensive service catalog. Partnerships appear to be internal subsidiaries rather than external third parties. The company maintains a strong brand presence with consistent messaging and professional content.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of security headers, and no visible exposure of sensitive data. The presence of ISO 27001 certification suggests organizational commitment to information security management. However, the lack of a dedicated security policy page and incident response contact reduces transparency and readiness perception. No vulnerability disclosure or security.txt file was found, limiting external reporting channels. Privacy compliance is strong with GDPR-aligned policies and cookie consent. Overall, the security maturity is good but could be enhanced by formalizing public security communications and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting.
  3. Provide explicit incident response contact information, such as a security@ or abuse@ email address.
  4. Verify and disclose domain registration details to improve transparency and trustworthiness.
  5. Continue to monitor and update privacy and cookie policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website uses a modern and stable technology stack with popular JavaScript libraries and icon fonts. Analytics are handled via Piwik PRO, indicating a preference for privacy-conscious tracking. The site is mobile optimized and accessible, with good SEO metadata and Open Graph tags. No CMS was detected, suggesting a custom-built platform which may reduce common CMS vulnerabilities but requires dedicated maintenance. Performance is moderate, with potential for optimization in loading speed. Security headers and HTTPS configuration are well implemented, contributing to a secure browsing experience. Technical risks are low, but ongoing maintenance and security policy transparency are recommended.
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.
