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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

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

AVS operates in a niche B2B market providing tailored digital loyalty and voucher platforms. Their competitive advantage lies in deep sector knowledge, long-standing client relationships, and comprehensive service offerings that cover complex multi-partner and clearing processes. Revenue streams likely include platform licensing, service fees, and production services via their lettershop. The company targets municipalities, retail chains, tourism boards, and publishers, leveraging partnerships with industry associations to maintain market relevance. Growth indicators include continuous product innovation and expansion into digital wallet solutions. The partnership ecosystem includes media houses and city marketing organizations, enhancing their reach and credibility.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and use of a consent management platform ensuring GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, or vulnerability disclosure mechanisms indicates room for improvement in transparency and preparedness. The use of self-hosted Matomo analytics reflects a privacy-conscious approach. Overall, the security posture is strong but could benefit from enhanced security headers and published security documentation.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to harden the website against common attacks.
  2. Publish a dedicated security policy page including incident response procedures and contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and trust.
  3. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced via dependencies.
  5. Enhance data protection officer contact visibility if applicable to strengthen GDPR compliance signals.

Technical notes

Notes

The website is built on TYPO3 CMS with a Bootstrap-based frontend, indicating a modern and maintainable infrastructure. JavaScript assets are compressed and loaded asynchronously, improving performance. The site is mobile-optimized with responsive design and accessibility features. Use of Usercentrics CMP and Matomo analytics shows attention to privacy and data protection. No hosting provider details were found, but domain name servers suggest a professional German hosting environment. Performance is moderate with potential for optimization in asset delivery and caching. Overall, the technical stack is robust and well-suited for the company's business needs.
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.
