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

4 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 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
    • 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

nic.at holds a reputable position as Austria's official domain registry, serving a broad customer base including businesses and organizations seeking domain registration and management. Their business model centers on domain registry operations and consulting for TLDs, including new gTLD application support. Revenue streams likely include domain registration fees, consulting services, and registry backend operations. The company maintains partnerships with related service providers and promotes transparency and compliance. Growth indicators include upcoming ICANN application rounds and active customer engagement through webinars and newsletters. The company ecosystem includes subsidiaries like tldbox GmbH and partner sites such as nic.versicherung and rcodezero.at.

Security posture

The website and associated services demonstrate a mature security posture with HTTPS enforced, presence of security headers, and ISO 27001 certification. Cookie consent mechanisms comply with GDPR, offering opt-in/out choices and detailed cookie information. No exposed sensitive data or vulnerable libraries were detected. However, explicit incident response and vulnerability disclosure policies are not publicly visible, representing an area for improvement. The use of Matomo analytics indicates a privacy-conscious approach to user tracking. Overall, the security culture appears strong, with room to enhance transparency on incident handling and vulnerability reporting.

Recommendations

  1. Publish a dedicated incident response and vulnerability disclosure policy page to improve transparency and trust.
  2. Implement and publicize a security.txt file to facilitate responsible vulnerability reporting.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance DNSSEC visibility and information on the website to reinforce DNS security assurances.
  5. Continue to monitor and optimize cookie and tracking practices to maintain GDPR compliance and user trust.

Technical notes

Notes

The website employs a modern technical stack including Bootstrap for responsive design and Matomo for analytics, ensuring good mobile optimization and accessibility. The site loads with moderate performance and includes proper meta tags for SEO. Security best practices such as HTTPS, CSRF tokens in forms, and cookie consent banners are implemented. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicit but the site is stable and professionally maintained. Opportunities exist to improve technical documentation and incident response visibility to further strengthen the technical maturity.
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.
