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

TEC Systems Systemhaus GmbH is a German IT service provider specializing in comprehensive IT infrastructure solutions, cloud concepts, software development, and consulting services primarily targeting small and medium-sized enterprises. The company maintains partnerships with major technology vendors such as IBM, Cisco, VMware, and TrendMicro, positioning itself as a trusted regional system house. The website reflects a professional and consistent brand image with clear contact information and service offerings. Technically, the site uses a custom PHP-based CMS with Bootstrap and jQuery frameworks, delivering moderate performance and good mobile responsiveness. However, there is room for improvement in accessibility and SEO optimization. Security posture is moderate; while no critical vulnerabilities are evident, the absence of security headers, visible incident response policies, and cookie consent mechanisms indicate gaps in security best practices and GDPR compliance. The domain WHOIS data is minimal but consistent with the company's German location and business history dating back to at least 2014. Overall, the website is trustworthy and professional but would benefit from enhanced security and privacy features to align with modern compliance standards.

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

8 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. 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
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

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

TEC Systems operates in the technology sector as an essential entity providing IT solutions to SMEs in Germany. Their business model revolves around delivering tailored IT infrastructure, cloud services, software solutions, and consulting. The company leverages partnerships with leading technology vendors to enhance credibility and service quality. Revenue streams likely include consulting fees, software sales, and managed IT services. The target customer segment is small and medium-sized enterprises seeking comprehensive IT support. The presence of downloadable terms of service and certifications like SPP Registered further reinforce their market position. Growth indicators include the launch of a cloud-based Warenwirtschaft system and active partner ecosystem. Strategic observations suggest a focus on maintaining strong vendor relationships and expanding cloud offerings to stay competitive.

Security posture

The website demonstrates a moderate security maturity level with no visible critical vulnerabilities or exposed sensitive data. However, the lack of HTTPS confirmation, absence of security headers, and missing incident response contact information highlight compliance and security gaps. GDPR compliance is partial, with a privacy policy present but no cookie consent mechanism. The company does not publicly disclose a data protection officer or vulnerability disclosure policy. These factors suggest limited readiness for incident response and potential risks in data protection practices. Enhancing security headers, implementing HTTPS, and establishing clear incident response channels would significantly improve the security posture and compliance alignment.

Recommendations

  1. Implement HTTPS with a strong SSL/TLS configuration to secure all website traffic.
  2. Add comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Deploy a cookie consent banner and update privacy policy to explicitly address GDPR compliance.
  4. Publish incident response contact information and establish a vulnerability disclosure policy.
  5. Regularly audit and update third-party libraries and frameworks to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a custom PHP-based CMS using Bootstrap and jQuery frameworks, with additional libraries like Fancybox and Flexslider for UI components. The design is responsive and mobile-friendly, with moderate performance. SEO optimization is basic, with minimal meta descriptions and no structured data like JSON-LD or Open Graph tags detected. Accessibility features are limited but present. No analytics or tracking scripts were found, indicating minimal user tracking. The hosting provider and SSL configuration details are not available, limiting full technical assessment. Opportunities exist to modernize the tech stack, improve SEO and accessibility, and enhance security configurations to reduce technical debt and improve user experience.
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.
