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

Deck.Gallery® operates in the content curation sector, focusing on presentation decks. Its competitive advantage lies in high-quality design curation and a clean user experience. Revenue streams likely include newsletter subscriptions and possibly partnerships or sponsored content, though no direct monetization is evident. The target audience is professional users interested in presentation design. The platform leverages partnerships with third-party form and newsletter providers (tally.so, loops.so) and analytics services (Cloudflare Insights, Umami). Growth indicators include active social media presence and regular content updates. The business ecosystem is small and focused, with no visible subsidiaries or parent companies.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and no visible sensitive data exposure. Rate limiting on newsletter signups mitigates abuse risks. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which limits transparency for security issues. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the security maturity is adequate for a small content platform but could be improved with formal policies and enhanced headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Create and publish terms of service to clarify user rights and responsibilities.
  4. Establish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  5. Enhance contact information with additional business details and consider adding a physical address or phone number for credibility.

Technical notes

Notes

The website uses a modern, standards-compliant tech stack with HTML5, CSS3, and JavaScript. It integrates third-party services for analytics (Cloudflare Insights, Umami) and newsletter management (loops.so, tally.so). Hosting is likely via Cloudflare, providing fast performance and HTTPS support. The site is mobile optimized with responsive design and good SEO metadata. Accessibility is basic but functional. No CMS or backend platform is explicitly detected. The site shows no signs of technical debt or performance bottlenecks. Opportunities exist to improve security headers and formalize compliance documentation.
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.
