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

5 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 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

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 marketplace targets digitally savvy consumers in Austria interested in energy products, entertainment subscriptions, insurance, and smart digital services. Its business model centers on aggregating partner offers with direct purchase or subscription links, supported by A1's brand trust and partner network. The presence of multiple product categories and exclusive deals indicates a diversified revenue stream. The use of advanced tracking and marketing tools suggests a focus on customer acquisition and retention through data-driven marketing. The partnership ecosystem includes A1.net and A1 Partnering, reinforcing its market position. Growth potential lies in expanding product offerings and improving technical infrastructure to enhance user experience and security.

Security posture

The website's security maturity is moderate to low due to the lack of a valid SSL certificate, absence of security headers, and missing DNSSEC and DMARC records. While no active vulnerabilities or malware were detected, these gaps expose the site to risks such as data interception, phishing, and DNS spoofing. The cookie consent implementation and privacy policy indicate awareness of GDPR compliance, but the missing security policies and incident response information highlight areas for improvement. The site should prioritize securing communications with a valid SSL certificate and implementing recommended DNS and email security measures to protect user data and maintain trust.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to secure all communications.
  2. Enable HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Implement DNSSEC and DMARC records to enhance domain and email security.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  5. Enhance contact information transparency by adding phone numbers and physical addresses where applicable.
Technical notes

Notes

The website uses a modern frontend stack with Alpine.js and Tailwind CSS, ensuring responsive design and good mobile optimization. Integration with Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, and Hotjar provides extensive analytics and marketing capabilities. However, the site exhibits slow load times (~6.6 seconds) and a large page size (~460KB), indicating potential for performance optimization. The hosting is managed by A1 Telekom Austria AG with dedicated DNS servers. No CMS was explicitly detected. Accessibility features are basic, and SEO is adequately addressed with proper meta tags and Open Graph data. Technical debt is moderate due to missing SSL and security headers, which should be addressed to reduce operational risks.
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.
