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

Coop Himmelb(l)au is a globally recognized architecture firm headquartered in Vienna, Austria, with additional offices in Tirana and Dubai. The firm specializes in innovative architectural design and urban planning, serving a diverse international clientele. Their portfolio includes a wide range of projects such as cultural institutions, residential buildings, office complexes, and mixed-use developments, highlighting their expertise and market presence in the real estate and architectural sectors. The website reflects a professional and comprehensive presentation of their work, targeting clients and stakeholders interested in cutting-edge architectural solutions. Technically, the website is built on a modern stack including Apache server, JavaScript frameworks, and analytics tools like Google Analytics and Matomo. It uses Kirby CMS inferred from URL patterns and asset paths, and is hosted on weber.cloud. The site is well-optimized for mobile devices and accessibility, with good SEO practices and clear navigation. However, performance metrics are moderate, indicating room for improvement in loading speed. From a security perspective, the site lacks HTTPS, which is a critical vulnerability. While some security headers are present, the absence of SSL/TLS encryption severely impacts the overall security posture. No incident response or security policy documents are found, and no vulnerability disclosure or security.txt files are present. Privacy compliance is good, with a comprehensive privacy policy and cookie consent mechanisms in place, including GDPR compliance indicators. Overall, the website is professionally designed and content-rich, supporting the firm's strong market position. However, the lack of HTTPS is a major security risk that must be addressed immediately to protect user data and maintain trust. Strategic recommendations include implementing SSL/TLS, enhancing security headers, and publishing security and incident response policies to improve the security maturity and compliance 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

8 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Coop Himmelb(l)au holds a strong position in the international architecture market, leveraging a large portfolio of high-profile projects across multiple continents. Their business model focuses on delivering architectural design and planning services with a global footprint, supported by offices in key regions. The firm targets institutional clients, developers, and public sector projects, emphasizing innovation and radical architectural concepts. Their competitive advantage lies in their established brand, extensive project experience, and consistent delivery of visionary architecture. The website supports lead generation through detailed project showcases, job listings, and newsletter subscriptions, indicating active engagement with potential clients and talent. Partnerships with social media platforms and use of marketing tools like MailChimp enhance their outreach and brand visibility. The firm appears to be large in size with a mature operational structure, founded in 1968, and maintains consistent branding and professional content quality.

Security posture

The current security posture of the website is weak due to the absence of HTTPS, exposing all data transmissions to interception and manipulation. While some security headers such as X-Frame-Options, X-XSS-Protection, and X-Content-Type-Options are implemented, the lack of SSL/TLS negates many benefits of these headers. No advanced security frameworks or certifications are indicated, and no incident response or vulnerability disclosure policies are published. The newsletter form includes consent mechanisms aligned with GDPR, but overall data protection practices could be improved by securing the transport layer and publishing clear security policies. The site does not use DNSSEC or CAA records, which could enhance domain security. Immediate remediation is required to implement HTTPS and strengthen security controls to reduce risk and comply with best practices.

Recommendations

  1. Implement a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Publish a formal security policy and incident response plan accessible from the website.
  4. Add DNSSEC and CAA records to improve domain name system security.
  5. Regularly audit and update security headers and ensure secure handling of user input in forms.

Technical notes

Notes

The website uses Apache as the web server and appears to be built on Kirby CMS, a flat-file CMS known for flexibility and performance. It leverages JavaScript for interactivity, including Turbolinks for navigation and Vimeo for video embedding. Analytics are implemented via Google Analytics and Matomo, providing comprehensive visitor tracking. The site is hosted on weber.cloud, as indicated by DNS nameservers. Performance is moderate with no explicit load time or resource count data, but lazy loading of images and responsive design indicate optimization efforts. Accessibility features such as ARIA roles and skip links are present, enhancing usability. SEO is supported by proper meta tags, Open Graph tags, and canonical links. However, the lack of HTTPS and session resumption mechanisms are technical risks that should be addressed promptly.
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.
