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

The website www.404s.design serves as a curated gallery showcasing creative 404 error page designs, aimed at inspiring designers and developers to transform typical error pages into engaging user experiences. It occupies a niche market position focused on creative web design inspiration. The site is small in scale and does not present explicit business entity information or contact details. Technically, the site is built on Webflow CMS, leveraging modern web technologies including GSAP for animations, Google Fonts, and privacy-conscious analytics via Fathom. The site is well-optimized for performance and mobile responsiveness, with a professional and consistent design. Security posture is adequate with HTTPS enforced, but lacks security headers and cookie consent mechanisms, which are recommended for enhanced protection and compliance. The absence of WHOIS data suggests privacy protection, which aligns with the site's small-scale creative nature. Overall, the site is trustworthy and safe for general audiences, with room for improvement in privacy compliance and security best practices.

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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

The business model centers on content curation and inspiration, targeting web designers and developers seeking innovative 404 page ideas. The platform facilitates user submissions, enhancing community engagement. Revenue streams and partnerships are not evident from the site content. The site maintains a clean and professional brand image, with consistent visual elements and trust signals such as HTTPS and a privacy policy. The lack of direct contact information and business registration details limits deeper business intelligence insights. The site’s ecosystem includes partnerships or affiliations with Webflow and Fathom Analytics, indicating reliance on modern web infrastructure and privacy-focused analytics.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth posture. No vulnerability disclosures or incident response contacts are provided, which could hinder rapid response to security incidents. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism or GDPR explicit indicators. The use of Fathom Analytics suggests a privacy-conscious approach to user tracking. Overall, the security posture is adequate for a small creative site but would benefit from implementing recommended security headers and enhanced privacy controls.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  2. Add a cookie policy and consent mechanism to improve GDPR compliance and user privacy transparency.
  3. Publish terms of service and a security policy page to enhance legal clarity and user trust.
  4. Consider establishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Add clear contact information or a contact form to improve business credibility and user support.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern front-end technologies such as GSAP for animations and Google Fonts for typography. It uses Fathom Analytics, a privacy-focused analytics tool, indicating a commitment to user privacy. The site is hosted on Webflow’s platform, ensuring fast loading times and good mobile optimization. The HTML and CSS are valid and well-structured, with responsive design considerations. However, the site lacks some accessibility features and security headers that could improve robustness and compliance. There is no evidence of technical debt or legacy technologies, suggesting a modern and maintainable codebase.
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.
