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 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';…

  3. GDPR outside view

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

    • 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

embed.tube occupies a niche market segment providing embed code generation services for video content across multiple platforms. Its competitive advantage lies in ease of use, live preview customization, and responsive design capabilities without requiring HTML knowledge. The business model is SaaS-based, likely monetized through advertising and possibly premium features, though no explicit monetization details are found. The target customer segments include web developers, bloggers, and small to medium website owners. The company maintains a lean operation with a small size and no subsidiaries or parent company indicated. The partnership ecosystem includes integrations with major video platforms and use of third-party analytics and advertising services. Growth indicators include active domain registration and ongoing content updates. Strategic observations suggest focusing on enhancing privacy compliance and expanding marketing transparency to strengthen market position.

Security posture

The security maturity of embed.tube is moderate to good. The site enforces HTTPS and avoids exposing sensitive data in its HTML content. However, it lacks advanced security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which could mitigate common web vulnerabilities. No incident response or security policy documentation is publicly available, which limits transparency and preparedness perception. The use of reputable third-party analytics and tracking services is noted, but cookie consent mechanisms are absent, posing potential GDPR compliance risks. No vulnerabilities or malware indicators were detected in the analyzed content. Overall, the security posture is adequate for the service type but would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement a comprehensive cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  2. Enable DNSSEC for the domain to improve DNS security and prevent spoofing attacks.
  3. Add security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen web security posture.
  4. Publish explicit security policies and incident response procedures to improve trust and preparedness.
  5. Consider adding terms of service and vulnerability disclosure policies to formalize user agreements and security reporting.

Technical notes

Notes

embed.tube is built using a modern React-based static site generator, Gatsby, which contributes to fast loading times and good performance. The site uses Material-UI for consistent styling and responsive design, ensuring good mobile optimization. Analytics and user behavior tracking are implemented via Google Analytics, Microsoft Clarity, and Hotjar, indicating a mature approach to user insights. Hosting appears to be with OVH sas, a reputable provider. The site includes structured data (JSON-LD) and Open Graph metadata for SEO and social media integration. No CMS is detected, suggesting a static site approach. Technical risks are minimal but include the absence of DNSSEC and security headers, which are recommended for further hardening. Overall, the technical infrastructure is modern, performant, and well-implemented with minor areas for improvement.
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.
