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

A-Trust GmbH is a well-established Austrian qualified trust service provider specializing in digital signature services, electronic identification, and compliance solutions. With over 25 years of experience, the company holds a strong market position in Austria and Europe, offering a broad portfolio of products tailored for businesses, the public sector, and private individuals. Their services include qualified signature services, signature platforms, firm seals, PSD2 certificates, and cash register certification solutions. The company emphasizes compliance, integrity, and user convenience, supported by certifications such as ISO 27001 and eIDAS compliance. Technically, the website is built on modern web standards with HTML5, CSS3, and JavaScript, hosted likely by A1 Telekom Austria AG, which also acts as the domain registrar. The site is mobile-optimized, well-structured, and performs moderately well. Privacy is respected with no tracking cookies or advertising scripts, and comprehensive privacy and security policies are published. However, some security headers are missing, and no explicit vulnerability disclosure or incident response contacts are provided. From a security perspective, the site enforces HTTPS and demonstrates good security hygiene with clear policies and certifications. The absence of tracking and advertising scripts enhances privacy compliance. The WHOIS data aligns well with the business claims, showing a consistent and legitimate registration. No suspicious patterns or privacy protection masking the registrant are present. Overall, A-Trust GmbH presents a professional, trustworthy, and secure digital presence with strong compliance and business credibility. Minor improvements in security headers and incident response transparency could further enhance their security posture.

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

6 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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

A-Trust GmbH operates in the digital trust and security sector, focusing on qualified electronic signatures and compliance services. Their competitive advantage lies in their long-standing market presence, ISO 27001 certification, and eIDAS qualified trust service provider status. The business model revolves around providing digital identity and signature solutions to enterprises, public sector entities, and private users, generating revenue through service subscriptions, certificate issuance, and platform usage. The company targets regulated industries and government sectors requiring high trust and compliance standards. Partnerships, such as with Governikus in Germany, indicate strategic expansion and ecosystem integration. The company shows growth indicators through certifications and awards like 'Great Place to Work'.

Security posture

A-Trust GmbH demonstrates a mature security posture with enforced HTTPS, ISO 27001 certification, and eIDAS compliance. The website avoids tracking technologies, enhancing privacy. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published vulnerability disclosure or incident response contacts represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The company’s security culture is supported by clear policies and certifications but could benefit from enhanced transparency and proactive vulnerability management disclosures.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen web security.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Provide clear incident response contact information (e.g., security@ or abuse@ email addresses) to improve transparency and responsiveness.
  4. Introduce a cookie consent mechanism even if no tracking cookies are used, to align with best privacy practices and user expectations.
  5. Regularly review and update privacy and security policies to maintain compliance with evolving regulations and standards.

Technical notes

Notes

The website uses standard modern web technologies (HTML5, CSS3, JavaScript) with a clean and professional design. Hosting and domain registration are managed by a reputable Austrian telecom provider, ensuring reliable infrastructure. The site is mobile-optimized and SEO-friendly with proper meta tags and canonical URLs. Performance is moderate, with potential for optimization. No CMS or advanced frameworks were detected, indicating a likely custom or lightweight implementation. The absence of tracking and advertising scripts reduces technical complexity and privacy risks. Opportunities exist to enhance technical security via HTTP headers and to improve accessibility features.
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.
