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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

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 operates in the niche market of vinyl record collectors, leveraging community and curated content to differentiate itself. Its business model centers on providing a free or possibly freemium digital service that aggregates and organizes vinyl collections, with potential for future monetization through premium features or partnerships. The company is small and newly founded, with no parent or subsidiary companies identified. Its competitive advantage lies in its clean interface, integration with Discogs, and social features like leaderboards and charts. The presence of social media channels and direct feedback mechanisms indicates an engaged user base and openness to community input. The use of privacy protection in domain registration aligns with typical startup practices. The platform's growth potential depends on expanding its user base and possibly integrating additional music services.

Security posture

The website enforces HTTPS and uses CSRF tokens in its forms, indicating attention to basic web security practices. Domain registration includes clientUpdateProhibited and related statuses, preventing unauthorized domain changes. However, DNSSEC is not enabled, and no advanced security headers (e.g., Content Security Policy, HSTS) were detected, which could improve protection against common web attacks. No explicit security policy or incident response contacts are published, which is a gap in transparency and readiness. The use of Yandex.Metrika is privacy-conscious but still represents a moderate level of user tracking. No vulnerabilities or exposed sensitive data were found in the analysis. Overall, the security posture is adequate for a small digital service but could be enhanced with additional measures and disclosures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and configure security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy and vulnerability disclosure page to improve transparency and encourage responsible reporting.
  4. Add incident response contact information (e.g., security@ or abuse@ email) to facilitate communication in case of security issues.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website is built with standard modern web technologies including HTML5, CSS3, and JavaScript, and supports Progressive Web App features for enhanced mobile experience. Hosting is provided by DigitalOcean, a reputable cloud provider. The site loads with moderate performance and is mobile-optimized with responsive design elements. SEO is supported by proper meta tags and Open Graph data for social sharing. Accessibility is basic but could be improved with additional ARIA attributes and semantic markup. The site uses Yandex.Metrika for analytics, which is less common globally but offers robust tracking capabilities. No CMS or major frameworks were explicitly detected, suggesting a custom or lightweight stack. Overall, the technical infrastructure is solid for a small-scale digital service with room for optimization and modernization.
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.
