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

Archello is a well-established online platform founded in 2007 that connects architecture professionals, designers, and manufacturers by showcasing architectural projects, products, and brands. The website serves as a comprehensive resource for discovering sustainable and innovative building materials and design solutions. Its market position is that of a reputable architecture media and product discovery platform with global reach. Technically, the website employs modern web technologies including Google Tag Manager for analytics, Cloudflare DNS for hosting and security, and responsive design elements for mobile optimization. Security posture is solid with HTTPS enforcement and domain transfer protections, but lacks DNSSEC and security headers, and does not provide visible privacy or cookie policies, which are areas for improvement. Overall, the website is professional, trustworthy, and content-rich, targeting architecture and design professionals worldwide.

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

3 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"

  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.

    • 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

  • 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

Archello operates in the Real Estate sector, focusing on architecture and design. Its business model revolves around content curation, product showcases, and community engagement, likely generating revenue through advertising, partnerships, and brand promotions. The platform targets architects, designers, manufacturers, and enthusiasts, providing them with detailed project insights and product information. The company benefits from a long domain history and consistent branding, positioning itself as a key player in architecture media. The absence of explicit contact information and privacy policies suggests potential areas to enhance transparency and user trust. The partnership ecosystem includes brands featured on the platform but no direct partner domains were identified in the provided data.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and domain status flags that prevent unauthorized transfers or updates. However, the lack of DNSSEC implementation and absence of security headers such as Content-Security-Policy and X-Frame-Options reduce its defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The presence of CSRF tokens indicates some protection for forms, but no explicit security or incident response policies are published. The site does not provide a vulnerability disclosure policy or security.txt file, which limits transparency for security researchers. Overall, the security posture is adequate but could be improved by adopting additional best practices and publishing relevant policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance and consent mechanisms.
  3. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information including security incident response contacts and data protection officer details.
  5. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager for analytics, Google Fonts for typography, and Swiper.js for interactive sliders. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile-optimized with responsive design and includes accessibility features at a basic level. SEO is supported by proper meta tags, Open Graph tags, and canonical links. Performance is moderate, with some optimization evident in font preloading and lazy loading of images. No explicit CMS was detected, suggesting a custom or proprietary platform. Technical risks include missing DNSSEC and security headers, which could be addressed to improve overall security and resilience.
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.
