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

TEC Technical Education Copenhagen is a well-established educational institution founded in 1997, specializing in vocational and technical education in the Copenhagen region. The website presents a professional and content-rich platform targeting students and companies interested in technical training, including vocational education (EUD), technical gymnasium (HTX), and continuing education courses. The institution emphasizes practical learning and real-world skills development. Technically, the website is built on the Umbraco CMS platform, utilizing modern web technologies and integrating analytics and marketing tools such as Google Tag Manager, Hotjar, and Klaviyo. The site is mobile-optimized and provides clear navigation and structured content. Security-wise, the site uses HTTPS and cookie consent mechanisms but lacks DNSSEC and visible security headers, and does not publish explicit security or incident response policies. Overall, the domain registration data aligns well with the business claims, supporting the site's legitimacy and trustworthiness.

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

6 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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"

    • 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

TEC holds a strong market position as a leading technical education provider in Denmark's capital region. Its business model focuses on delivering diverse educational programs for youth and adults, including partnerships with companies for apprenticeships and sponsorships. The presence of multiple campuses and a broad course catalog indicates a large organizational size. The institution leverages digital marketing and analytics to engage prospective students and partners. The social media presence across Facebook, Instagram, LinkedIn, and YouTube supports community engagement and brand visibility. No parent or subsidiary companies were identified, indicating TEC operates as an independent entity. The website content and structured data reflect a consistent and credible business identity.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS encryption and a GDPR-compliant cookie consent mechanism via Cookiebot. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces the overall security robustness. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, which could hinder transparency and responsiveness to security incidents. The use of third-party analytics and marketing scripts introduces moderate user tracking, which is managed through consent but requires ongoing oversight. There are no visible vulnerabilities or exposed sensitive data in the analyzed content. Enhancing security headers and publishing security policies would improve the security maturity.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize unnecessary data collection.

Technical notes

Notes

The website is built on the Umbraco CMS platform, leveraging modern frontend technologies including CSS3 and JavaScript. It integrates multiple analytics and marketing tools such as Google Tag Manager, Hotjar, Ahrefs Analytics, and Klaviyo, indicating a mature digital marketing infrastructure. The site is mobile-optimized with good SEO practices including meta tags and structured data in JSON-LD format. Performance is moderate, with video content and multiple images that may impact load times. Accessibility features are basic but present. The technical stack is modern and well-maintained, though opportunities exist to improve security configurations and performance optimizations.
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.
