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

HTL Zeltweg is a medium-sized Austrian educational institution specializing in technical and vocational education, particularly in mechanical engineering and construction technology. The website reflects an active institution with a focus on practical training, robotics, and international cooperation. The technical infrastructure is based on WordPress with a modern plugin ecosystem, but suffers from critical security shortcomings such as the absence of HTTPS and a valid SSL certificate. The lack of cookie consent and privacy compliance mechanisms further reduces trustworthiness. While the site provides clear contact information and social media presence, the security posture is weak, exposing the institution to risks related to data interception and user trust. Strategic improvements in SSL deployment, security headers, and privacy compliance are essential to enhance the institution's digital maturity and protect its stakeholders.

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

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

HTL Zeltweg operates as a public technical school with a strong regional presence in Austria. Its competitive advantage lies in specialized programs like robotics and smart engineering, supported by active partnerships with industry and other educational institutions. The business model focuses on providing comprehensive technical education and career services, targeting students and working professionals. The institution maintains a consistent brand and regularly updates its content, indicating a commitment to engagement and transparency. However, the absence of advanced digital marketing and analytics tools suggests room for growth in digital outreach and data-driven decision-making.

Security posture

The website's security posture is currently poor due to the lack of HTTPS and a valid SSL certificate, which is a critical vulnerability. Additional missing security controls include the absence of HSTS, DMARC, DNSSEC, and security.txt files. No incident response or vulnerability disclosure policies are published, limiting the institution's ability to manage security incidents effectively. While no known vulnerabilities or malware were detected, the insecure configuration exposes users to potential data interception and undermines trust. Immediate remediation of SSL/TLS issues and implementation of standard security headers and policies are recommended to mitigate risks.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP Strict Transport Security (HSTS) to enforce secure connections.
  3. Publish and maintain DMARC, DNSSEC, and CAA DNS records to enhance domain and email security.
  4. Add a security.txt file and clearly publish incident response contact information.
  5. Deploy a cookie consent mechanism to comply with privacy regulations and improve user trust.
Technical notes

Notes

The website is built on WordPress 6.7.2 running on an Apache server hosted by world4you.at. It uses common plugins such as Yoast SEO, Contact Form 7, and The Events Calendar. The site includes responsive design elements and is mobile-optimized. However, performance data is missing, and the site lacks HTTPS, which is a major technical deficiency. The JavaScript stack includes jQuery and underscore.js, with some custom scripts for UI components. The site structure is well-organized with clear navigation menus and semantic HTML. Opportunities exist to improve performance, security headers, and analytics configuration to modernize the technical infrastructure.
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.
