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. 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. 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 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 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 is positioned as a niche independent design and product studio with a strong personal brand. Key competitive advantages include a well-curated design gallery, a social platform for book lovers, and a collaborative product studio model. Revenue streams appear to be a mix of platform monetization via sponsorships and submission fees, alongside consulting and design services. The target customer segments are tech-savvy individuals, startups, and creative professionals. The partnership ecosystem includes collaborations with investors and design studios. Growth indicators include a user base exceeding 100k for Literal and ongoing new ventures. Strategic observations suggest focusing on expanding monetization and formalizing compliance to enhance trust.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, comprehensive security headers, and no visible vulnerabilities or exposed sensitive data. However, there is a lack of formal security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for compliance and transparency. Data protection practices are implicit due to minimal data collection (no forms). The site lacks GDPR-specific compliance indicators such as privacy and cookie policies, which should be addressed. Overall, the security culture appears proactive but could benefit from formal documentation and user communication enhancements.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement a security.txt file or vulnerability disclosure policy to enhance transparency and incident response readiness.
  3. Add visible contact phone number and/or physical address to improve business credibility and user confidence.
  4. Regularly review and audit third-party scripts and tracking tools for privacy and security compliance.
  5. Consider adding user consent mechanisms for cookies and tracking to align with privacy regulations.

Technical notes

Notes

The website is built using modern web technologies including Next.js (React framework), Firebase backend services, and Cloudinary for media management. It leverages Google Tag Manager for analytics and tracking. The site is hosted on Google Cloud infrastructure, ensuring scalability and reliability. Performance is optimized with preconnects, preloads, and responsive design. Accessibility and SEO best practices are followed with proper meta tags and structured content. There is no evidence of technical debt or outdated libraries. Opportunities exist to further enhance compliance and security documentation to reduce risk and improve user trust.
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.
