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

      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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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.

Business context

Business profile

Textklinik GmbH operates in the language services sector, focusing on high-quality, cost-sensitive, and professional linguistic support for advertising agencies and companies. Their competitive advantage lies in their experienced team of linguists, strict quality control processes, and ISO certification. The business model is service-oriented, relying on expert human resources and a broad network of native speakers. Revenue streams likely come from project-based language services and training sessions. The company maintains strong client relationships, evidenced by numerous testimonials from reputable clients. Growth indicators include a long-standing market presence and continuous network expansion, especially in interpreting services for non-European languages. The partnership ecosystem includes professional networks and social media presence on LinkedIn and Xing.

Security posture

The security maturity of Textklinik GmbH is good, with HTTPS enforced and no exposed sensitive data detected. The website follows best practices in content quality assurance through the four-eyes principle, reducing risks of errors. However, the absence of explicit security headers and incident response contact information indicates room for improvement. There is no visible vulnerability disclosure mechanism or security.txt file. GDPR compliance is evident through comprehensive privacy and cookie policies. The lack of analytics and tracking scripts reduces privacy risks. Overall, the security posture supports business continuity and data protection but would benefit from formalized incident response and enhanced HTTP security headers.

Recommendations

  1. Implement and configure HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish a security.txt file or dedicated vulnerability disclosure page with contact information for security incidents.
  3. Add explicit incident response contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and readiness.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.
  5. Enhance marketing transparency by disclosing any tracking or analytics tools if used in the future.

Notes

The website is built using Webflow CMS, leveraging jQuery 3.5.1 and Webflow's JavaScript bundles for interactivity and layout. Hosting is provided via Webflow's CDN infrastructure, backed by Amazon Cloudfront, ensuring fast content delivery and global availability. The site is mobile-optimized with responsive design and good accessibility features. SEO is supported by appropriate meta tags, Open Graph, and Twitter card metadata. No heavy analytics or advertising scripts are detected, which benefits privacy and performance. The technical stack is modern and well-maintained, with no visible technical debt or deprecated technologies. Opportunities exist to enhance security headers and formalize incident response mechanisms.
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.
