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

3 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 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 SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The website positions Stopline as a key national authority for reporting and combating illegal online content in Austria. Its partnerships with EU programs and organizations like ISPA and INHOPE strengthen its operational ecosystem. The business model is non-commercial, focusing on public service and legal compliance. The target audience includes internet users encountering illegal content and stakeholders in child protection and extremism prevention. The site’s content and services reflect a mature, well-established entity with a history dating back over 20 years. The presence of detailed cookie consent and privacy policies indicates a strong commitment to data protection and user privacy.

Security posture

Stopline exhibits a mature security posture with HTTPS enforced site-wide and use of CSRF tokens to protect forms. The cookie consent banner provides granular control over cookie categories, enhancing privacy compliance. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap that could be addressed to further harden the site. No vulnerability disclosures or incident response contacts are publicly available, which could limit transparency in security incident handling. No vulnerable or outdated libraries were detected. Overall, the site is secure but could improve in formalizing and publishing security policies and headers.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information.
  2. Add standard security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and update third-party libraries and analytics configurations to ensure ongoing security and privacy compliance.

Technical notes

Notes

The website uses a combination of jQuery 2.2.4, Bootstrap CSS classes, and Matomo analytics for tracking. The cookie consent mechanism is custom-built by DataReporter GmbH, providing detailed cookie category management and opt-out options. Hosting appears to be managed by nic.at GmbH, consistent with the Austrian domain and address. Performance is moderate with asynchronous loading of analytics scripts. The site is mobile responsive with good navigation clarity. No CMS was explicitly detected, suggesting a custom or static site architecture. Technical debt appears low, but modernization opportunities include updating jQuery to a more recent version and enhancing accessibility compliance.
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.
