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

Excellence AG is an international technology partner specializing in engineering and IT services with a strong focus on green technology and sustainability. The company operates multiple offices across Germany and the Netherlands, offering green tech job opportunities and supporting sustainable projects in energy and transportation sectors. Their website is professionally designed, content-rich, and targets professionals interested in green technology careers and partnerships. Technically, the website is built on modern frameworks such as Nuxt.js and Vue.js, integrated with Google Tag Manager and social login plugins for LinkedIn and Xing. The hosting appears to be on AWS infrastructure. However, the site lacks a valid SSL certificate and does not serve content over HTTPS, which is a critical security shortfall. Performance metrics are not available, but the site shows good mobile optimization and SEO practices. From a security perspective, the absence of HTTPS and modern TLS protocols significantly lowers the security posture. No advanced security headers or incident response policies are evident. Privacy compliance is partially met with a comprehensive privacy policy and GDPR consent statements on forms, but no cookie consent mechanism is detected. Business credibility is supported by ISO 9001 certification, multiple office locations, and professional content. Overall, the website presents a trustworthy and professional business front but requires urgent security improvements, especially enabling HTTPS and enhancing security headers, to protect user data and improve trustworthiness. Strategic recommendations include SSL implementation, security header enhancements, and adding explicit cookie consent mechanisms to align with privacy regulations.

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

7 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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';…

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

Excellence AG positions itself as a key player in the green technology engineering and IT services market, focusing on sustainable energy and transportation solutions. Their business model combines project consulting and recruitment services targeting green tech professionals. The company leverages a multi-location presence in Germany and the Netherlands to serve a broad European market. Their partnerships and social media presence indicate active engagement with professional networks. The company’s ISO 9001 certification and detailed project case studies demonstrate quality and innovation focus. Growth indicators include a diverse portfolio of green projects and a dedicated careers section emphasizing life at Excellence. The business ecosystem appears well-structured with clear branding and consistent messaging.

Security posture

The current security maturity level is low due to the lack of HTTPS and valid SSL certificates, exposing users to potential data interception risks. The absence of HSTS, OCSP stapling, and session resumption further weakens the security posture. No explicit incident response or vulnerability disclosure policies are found, indicating limited preparedness for security incidents. Privacy compliance is partial, with GDPR consent on forms but missing cookie consent banners. The use of third-party tracking pixels (Facebook, LinkedIn) suggests moderate user tracking, which should be transparently managed. Overall, the security culture appears nascent and requires significant enhancements to meet industry best practices and regulatory requirements.

Recommendations

  1. Implement a valid SSL/TLS certificate and serve the entire website over HTTPS to secure user data and improve trust.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and configure HSTS with includeSubDomains and preload options.
  3. Add comprehensive security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Introduce a cookie consent mechanism compliant with GDPR and ePrivacy Directive to inform users about tracking.
  5. Develop and publish clear security and incident response policies, including vulnerability disclosure guidelines.
  6. Regularly audit third-party scripts and tracking pixels to minimize privacy risks and ensure compliance.
  7. Enhance accessibility features and performance optimizations to improve user experience across devices.

Technical notes

Notes

The website utilizes a modern JavaScript framework stack with Nuxt.js and Vue.js, supported by a headless CMS (Strapi) backend. Integration with Google Maps API and social login plugins for LinkedIn and Xing enhances functionality. However, the lack of HTTPS and TLS support is a critical technical deficiency. Performance data is missing, but the site shows good mobile responsiveness and SEO meta tags. Hosting on AWS IP indicates reliable infrastructure. Technical debt is moderate, with opportunities to improve security configurations and implement performance monitoring. The site’s architecture supports scalability and content management but requires security modernization to mitigate risks.
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.
