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

Back Simonsen is a Swiss architecture firm based in Basel, founded in 2015 by Valerie Simonsen and Lukas Back. The firm offers architectural design, planning, and project management services for private and public clients, focusing on sustainable and high-quality building culture. Their portfolio includes interior renovations, private homes, residential complexes, public buildings, and urban quarters. The website presents a professional image with clear contact details and project listings, targeting clients in the Swiss real estate and construction sectors. Technically, the site is built with modern React technology and CSS modules, providing a good user experience and mobile optimization. However, the site lacks advanced security headers and cookie consent mechanisms, which are recommended for compliance and security. No blocking or WAF protections hinder content access, and the domain registration data aligns well with the business profile, supporting legitimacy. Overall, the website is a good representation of a small architecture firm with room for improvement in security and privacy compliance.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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';…

  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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 · found on this site
  • 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 operates in the real estate and architecture sector, serving both private and public clients primarily in Switzerland. Their competitive advantage lies in their commitment to sustainable and quality architecture, supported by participation in design competitions. The business model is service-oriented, focusing on architectural design and project management. The firm is small-sized, with a clear local market presence in Basel. The website supports business credibility with detailed project portfolios and team biographies. There is limited digital marketing or analytics presence, indicating a focus on direct client engagement rather than broad online marketing. No partnerships or subsidiaries are indicated, suggesting an independent operation.

Security posture

The website demonstrates a basic security posture with HTTPS implied but no explicit security headers detected in the provided data. There is no evidence of vulnerability disclosures, incident response contacts, or security policies. The absence of cookie consent mechanisms and security headers represents compliance and security gaps. No forms or input fields reduce the attack surface, but the site would benefit from implementing standard security best practices such as Content-Security-Policy and X-Frame-Options headers. The WHOIS data shows no privacy protection, which aligns with transparency for a professional service firm. Overall, the security posture is moderate but requires enhancements to meet best practices and regulatory compliance fully.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy regulations.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Verify and enforce SSL/TLS configuration to ensure secure communications.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built using React and Webpack with CSS modules and custom fonts, indicating a modern front-end technology stack. The site is mobile optimized and has a clear navigation structure. No CMS or third-party analytics tools are detected, suggesting a custom-built or static site approach. Performance is moderate, with no explicit performance optimization indicators found. Accessibility is basic but could be improved with ARIA attributes and semantic HTML enhancements. SEO is basic with meta description and viewport tags present but no Open Graph or JSON-LD structured data detected. The absence of external analytics or tracking scripts indicates minimal user tracking, supporting privacy compliance.
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.
