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. 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';…

  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

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

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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention jk-works.de, from OffSeq Breach.

No leaked records found

Breach holds no records for jk-works.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

JK.works mediatec operates as a service-oriented business focusing on IT infrastructure and digital solutions for regional clients. Their competitive advantage lies in their long-standing experience, Microsoft partnership, and comprehensive service portfolio. The business model centers on direct client engagement with personalized support, reflected in detailed team contacts and support center access. The absence of social media and analytics tools suggests a focus on direct client relationships rather than broad digital marketing. Growth indicators include ongoing projects and server maintenance counts. The company maintains a clean partnership ecosystem with no suspicious or unrelated domains linked.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a cookie consent mechanism supporting GDPR compliance. However, the lack of visible security headers and absence of a published security policy or incident response contacts indicate areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The company should consider publishing explicit security and incident response policies to improve transparency and readiness. Overall, the security posture is good but could be elevated to excellent with additional measures.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider integrating analytics with privacy-respecting configurations to gain insights while maintaining compliance.

Technical notes

Notes

The website is built on OctoberCMS, leveraging a modern front-end stack including Bootstrap, jQuery, and FontAwesome. Performance is moderate with good mobile responsiveness and SEO optimization. The hosting provider is Schlund Technologies, a reputable German host. The site uses cookie consent scripts and standard plugins for UI enhancements. No broken elements or errors were detected in the HTML content. Opportunities exist to improve accessibility and implement advanced security headers. The technical infrastructure supports the business needs effectively with room for modernization in security and analytics.
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.
