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

aspern Seestadt is a visionary urban development project located in Vienna, Austria, targeting investors, companies, and individuals seeking modern urban living by the lake. The website presents a professional and consistent brand image with a focus on real estate and city planning services. Technically, the site employs modern JavaScript frameworks such as Vue.js and Alpine.js, integrates Matomo for analytics, and uses Pimcore for personalization, indicating a mature digital infrastructure. Security measures including HTTPS and security headers are well implemented, though privacy and cookie policies are absent, which is a compliance gap. Overall, the site is trustworthy and well-positioned in its market segment but would benefit from enhanced privacy compliance and clearer contact information.

Priority findings

2 findings rated critical or high. Fix these first.

  1. 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 256-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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 business operates in the real estate and urban development sector with a focus on visionary city planning in Vienna. It targets investors and companies interested in development opportunities. The business model revolves around promoting and managing urban development projects, likely generating revenue through real estate sales, leasing, and partnerships. The website's market position is strong as a recognized European development area. The absence of explicit contact details and policy documents suggests room for improvement in transparency and customer engagement. The use of advanced personalization tools indicates a strategic approach to user experience and marketing.

Security posture

The website demonstrates a good security posture with HTTPS enforced and multiple security headers present, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of a published security policy, incident response contacts, or vulnerability disclosure mechanisms limits the site's readiness for security incidents and transparency. Privacy compliance is weak due to missing privacy and cookie policies, which could pose regulatory risks under GDPR. Enhancing these areas would improve the overall security maturity and compliance stance.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit consent mechanisms to ensure GDPR compliance.
  2. Add terms of service and security policy documents accessible from the website footer or main navigation.
  3. Provide clear and verified contact information including dedicated security and incident response contacts.
  4. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to meet recognized standards and improve user inclusivity.

Technical notes

Notes

The website uses a modern tech stack including Vue.js and Alpine.js for frontend interactivity, Matomo for privacy-focused analytics, and Pimcore for content management and personalization. The site loads CSS and JS assets efficiently and uses Mapbox GL for interactive maps. Performance is moderate with room for optimization. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. No CMS vulnerabilities or outdated libraries were detected. Hosting details are not explicit but the domain and assets suggest a professional hosting environment. Technical debt appears low, but privacy and compliance technical implementations need enhancement.
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.
