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

5 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. 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

  • 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

Stamen Design operates in the technology sector focusing on data visualization and cartography services. Their business model is service-based, delivering custom solutions and educational offerings. The company targets clients who need advanced data storytelling and mapping products, leveraging their unique design approach and technical expertise. Their long domain age and award recognition indicate a stable market presence. Partnerships include web development collaborations, and their marketing employs standard analytics and tracking tools. The company maintains a clear brand identity and consistent messaging, supporting growth and client trust.

Security posture

The website employs HTTPS with a valid SSL configuration, uses Google reCAPTCHA to protect forms from spam, and implements a comprehensive cookie consent banner compliant with GDPR. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident and should be added to enhance protection. There is no published security policy or incident response contact, which are recommended for transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be strengthened with additional headers and formal policies.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page detailing security practices and incident response procedures.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance transparency by providing direct security contact channels such as security@ or abuse@ email addresses.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are in use.

Notes

The website is powered by WordPress CMS with a modern tech stack including Vue.js for frontend interactivity and D3.js for data visualization. It integrates Google Tag Manager, LinkedIn Insight, and ActOn for marketing and analytics. The site uses Gravity Forms for data collection with reCAPTCHA for spam prevention. Hosting appears to be on AWS infrastructure based on DNS records. Performance is moderate with room for optimization. The site is mobile responsive and accessible, with good SEO practices implemented via Yoast SEO. Technical debt is low, but improvements in security headers and performance tuning could enhance robustness and user experience.
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.
