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

2 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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.

    • 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

Google LLC operates Firebase Hosting as part of its cloud services portfolio, targeting developers and enterprises needing scalable hosting and app development tools. The business model is platform-as-a-service, monetized through cloud usage and premium Firebase features. The company benefits from Google's brand strength, extensive cloud infrastructure, and integration capabilities. The target customers include startups, SMBs, and large enterprises building mobile and web applications. Firebase Hosting's competitive advantage lies in its seamless integration with other Firebase and Google Cloud products, ease of use, and global scalability. The ecosystem includes related Google services and developer tools, enhancing customer retention and cross-selling opportunities. The website content and structure reflect a professional and enterprise-grade offering with excellent branding consistency.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page, vulnerability disclosure program, or incident response contact information represents a gap in transparency and readiness communication. Privacy policies are comprehensive and GDPR compliant, reflecting strong data protection practices. The lack of explicit security contact channels may limit rapid incident reporting and response. Overall, the security posture is robust but could be improved by publishing detailed security and incident response information to enhance trust and compliance.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance frameworks.
  2. Establish and publicize a vulnerability disclosure program with clear contact channels.
  3. Add data protection officer contact information to improve GDPR transparency.
  4. Enhance visibility of official contact information for support and security inquiries.
  5. Maintain and regularly update WHOIS records to ensure domain registration transparency.

Technical notes

Notes

The website is built on a modern technology stack leveraging Google’s proprietary frameworks and cloud infrastructure. It uses Google Fonts, Material Icons, and integrates Google Analytics for tracking. The site is optimized for performance with fast loading times and excellent mobile responsiveness. Accessibility features are present but could be further enhanced. SEO practices are good with proper meta tags and structured data (JSON-LD) for articles. Hosting is provided by Google Cloud Platform, ensuring high availability and scalability. There is no detected CMS, indicating a custom or static site generation approach. The technical implementation reflects a mature and well-maintained digital asset suitable for enterprise use.
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.
