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

4 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 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
    • 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

Stagetimer.io occupies a niche in event timing and production tools, offering a unique remote-controlled timer solution that integrates with industry-standard software like OBS Studio and Stream Deck. Its competitive advantage lies in ease of use, cross-device compatibility, and real-time communication features. Revenue streams include subscription plans and one-time licenses, with payment processing via Paddle. The target customers are event professionals, educators, and broadcasters. The company demonstrates growth through extensive user adoption and partnerships. The ecosystem includes integrations and desktop apps for offline use, enhancing market reach and customer retention.

Security posture

The website exhibits a mature security posture with enforced HTTPS, multiple security headers, and a cookie consent mechanism aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of DNSSEC and a public vulnerability disclosure policy are areas for improvement. Incident response contacts are not publicly listed, which could hinder rapid communication in case of security events. Overall, the security culture appears proactive but could benefit from formalized disclosure and incident response transparency.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Add explicit incident response contact information on the security page.
  4. Consider obtaining recognized security certifications to boost customer trust.
  5. Regularly audit and update third-party dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using the Astro framework, leveraging Firebase for backend services including authentication and storage, and Google Cloud Functions for serverless operations. It uses SVG graphics for UI elements and integrates with third-party services like Paddle for payments and Google Analytics for tracking. The site is hosted behind Cloudflare DNS, ensuring fast DNS resolution and protection. Performance is optimized with responsive design, lazy loading of images, and modern CSS. No CMS is detected, indicating a custom or static site generation approach. The technical stack is modern and well-suited for scalable SaaS delivery, with minor opportunities for further security hardening.
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.
