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

820 is a Zurich-based architecture studio specializing in innovative designs that integrate technology and environmental considerations. Led by Nicolas König and Lewis Horkulak, the studio emphasizes techno-environmental synergies and speculative spatial scenarios to foster deeper environmental integration. Their portfolio showcases a range of projects, competitions, and installations, highlighting a strong presence in the architectural design community with multiple awards and exhibitions. Technically, the website is built on the Cargo Collective platform, utilizing modern web standards including HTML5, CSS3, and JavaScript. The site is well-optimized for mobile devices and presents a professional, visually rich portfolio. However, there is room for improvement in accessibility and SEO practices. From a security perspective, the site uses HTTPS and does not expose sensitive data or forms, reducing attack surface. Nonetheless, it lacks important security headers and does not provide explicit security policies or incident response contacts, which could be enhanced to improve trust and compliance. Overall, the website reflects a credible and professional architecture studio with a strong digital presence but would benefit from enhanced privacy, security, and compliance disclosures to align with best practices and regulatory requirements.

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. 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"

    • 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';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

820 operates as a small, specialized architecture studio targeting clients and collaborators interested in environmentally integrated and technologically advanced architectural solutions. Their competitive advantage lies in their focus on speculative and techno-environmental design, supported by recognized awards and collaborations with other studios such as dorsa + 820. The business model centers on project-based architectural design, competitions, and installations, with a strong emphasis on innovation and environmental integration. The presence of exhibitions and publications indicates active engagement with the architectural community and potential for growth. Partnerships with other design collectives enhance their market reach and creative capacity.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data or vulnerable libraries. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security represents a gap in defense-in-depth strategies. The lack of a vulnerability disclosure policy or security contact channels limits the studio's readiness for incident response and transparency. No forms or user input fields reduce risk but also limit interaction capabilities. Compliance with GDPR and other privacy regulations is not clearly addressed, which could pose regulatory risks. Overall, the security posture is adequate for a portfolio site but requires enhancements for improved resilience and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen security posture.
  3. Establish a vulnerability disclosure policy and provide dedicated security contact channels (e.g., security@820.ch).
  4. Conduct regular security audits and update third-party dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website is hosted on the Cargo Collective platform, leveraging modern web technologies such as HTML5, CSS3, and JavaScript. It uses custom variable fonts (Diatype Variable) for branding consistency. The site is mobile-optimized with responsive design elements and includes multimedia content like images and videos to showcase projects. Performance is moderate, with no evident heavy scripts or trackers. However, the site lacks advanced SEO structured data (e.g., JSON-LD) and accessibility enhancements. The absence of analytics or tracking scripts suggests minimal user data collection, aligning with privacy-conscious design. Technical debt appears low, but opportunities exist to improve security headers and compliance-related metadata.
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.
