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

Computer Leipzig GmbH is a small, established IT service provider based in Leipzig, Germany, specializing in business software, IT consulting, managed services, and infrastructure solutions. Since 1999, it has supported over 200 companies and public clients with tailored IT solutions, focusing on ERP systems, e-commerce, and digital transformation. The company emphasizes privacy and open-source software, catering primarily to SMEs and public sector organizations in Leipzig and beyond. Technically, the website is built on WordPress with standard plugins such as jQuery and a cookie consent manager, offering good mobile optimization, accessibility, and SEO practices. The site is served over HTTPS with a cookie consent mechanism, but lacks some advanced security headers and explicit incident response policies. Security posture is solid with no visible vulnerabilities or exposed sensitive data, but the absence of WHOIS data and domain registration inconsistencies reduce overall trustworthiness. Privacy compliance is strong with comprehensive policies and consent mechanisms in place. Overall, the website presents a professional and trustworthy image with room for improvement in domain registration transparency and security header implementation. Strategic recommendations include verifying domain registration, enhancing security headers, and publishing incident response information.

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.

    • 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 24 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality

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

Computer Leipzig operates in the technology sector, focusing on IT services for SMEs and public clients primarily in Leipzig and the surrounding regions. Its competitive advantage lies in personalized consulting, use of open-source software, and a long-standing presence since 1999. The business model revolves around service delivery including managed IT services, ERP implementation, and e-commerce solutions. Revenue streams likely include consulting fees, software licensing, and support contracts. The company maintains a strong local partnership ecosystem, serving notable regional clients and cultural institutions. Growth indicators include a stable client base and expansion into broader German regions and neighboring countries. The company’s operations emphasize privacy and digital sovereignty, aligning with European data protection standards.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a robust cookie consent mechanism aligned with GDPR requirements. No security headers were detected, which is a gap that could be exploited in certain attack vectors such as clickjacking or MIME sniffing. No incident response or security policies are published, limiting transparency in security governance. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of analytics and third-party tracking reduces attack surface and privacy risks. Overall, the security maturity is good but could be enhanced by implementing recommended HTTP security headers and publishing security policies.

Recommendations

  1. Verify and update domain WHOIS registration to ensure transparency and trust.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a security.txt file and incident response policy to improve security governance and communication.
  4. Regularly audit WordPress plugins and themes for vulnerabilities and keep them updated.
  5. Consider integrating analytics with privacy-respecting configurations to gain user insights while maintaining compliance.

Technical notes

Notes

The website is built on WordPress CMS using jQuery and a cookie consent plugin, indicating a standard and widely supported technology stack. The site is mobile optimized and accessible with good SEO metadata including Open Graph and Twitter Card tags. Performance is moderate, with no explicit hosting provider identified. The site uses HTTPS with a valid SSL certificate, ensuring encrypted communications. No advanced frameworks or platforms were detected. The site lacks some modern security headers and does not expose analytics or marketing scripts, which reduces complexity but also limits business intelligence capabilities. Overall, the technical implementation is solid with opportunities for modernization and enhanced security.
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.
