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

DONAU Versicherung AG Vienna Insurance Group is a large Austrian insurance company offering a broad range of insurance products including health, pension, car, home, and legal protection insurance for private and business customers. The website is professionally designed with excellent content quality, clear navigation, and good mobile optimization. It uses TYPO3 CMS and integrates modern tools such as TagCommander for tag management and Empathy Portal for live chat support. Despite these strengths, the website suffers from a critical security issue: the SSL certificate is invalid or missing, which undermines user trust and security. Privacy and cookie policies are well implemented with consent mechanisms, reflecting good GDPR compliance. The company demonstrates strong business credibility with certifications and high customer ratings. Overall, the site is functional and trustworthy but requires urgent SSL certificate remediation to improve 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

7 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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 company positions itself as a key player in the Austrian insurance market, backed by the Vienna Insurance Group. It targets both private and business customers with tailored insurance solutions. The business model relies on both online and offline customer engagement, supported by a comprehensive service and contact infrastructure including live chat and customer portals. The presence of multiple certifications and positive customer feedback indicates a strong market reputation. The website content is rich and relevant, supporting customer education and product promotion. The company leverages social media extensively for marketing and customer interaction. No suspicious or inconsistent domain registration data was found, supporting legitimacy.

Security posture

The website implements several security headers such as X-Content-Type-Options, Referrer-Policy, X-Frame-Options, and X-XSS-Protection, which are good security practices. However, the SSL certificate is invalid or missing, which is a critical vulnerability that severely impacts the security score. TLS protocols are not enabled, and no strong cipher suites are detected. HSTS header is present in meta tags but not effectively enforced due to SSL issues. No major vulnerabilities like Heartbleed or POODLE are detected. Incident response information and security policy details are limited on the site. Overall, the security posture is moderate but requires immediate SSL certificate correction and enhancement of incident response visibility.

Recommendations

  1. Obtain and correctly install a valid SSL/TLS certificate to secure HTTPS connections.
  2. Enable and enforce HSTS with proper SSL configuration to prevent downgrade attacks.
  3. Implement OCSP stapling to improve SSL performance and security.
  4. Publish clear incident response and vulnerability disclosure policies with contact channels.
  5. Regularly audit and update security headers and review third-party scripts for vulnerabilities.
Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system. It uses modern JavaScript libraries and SVG icons for UI elements. TagCommander is used for tag management, and Empathy Portal provides live chat functionality. The site is hosted on infrastructure associated with A1.net, as indicated by DNS records. Performance is slow with a load time of over 8 seconds and a large page size (~366 KB) with 44 resources, suggesting optimization opportunities. Accessibility features such as skip links and ARIA labels are implemented, and SEO meta tags including Open Graph and Twitter cards are present. The site is mobile optimized with responsive design. Overall, the technical infrastructure is solid but could benefit from performance tuning and SSL improvements.
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.
