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

Firebase Hosting benefits from Google's extensive cloud infrastructure and brand recognition, targeting developers and enterprises needing reliable static site hosting. The business model is SaaS/PaaS, generating revenue through cloud service usage. The ecosystem includes complementary Firebase products such as Authentication, Cloud Functions, and Firestore, creating a comprehensive development platform. The website's content and navigation clearly communicate product offerings and benefits, supporting customer acquisition and retention. Partnerships and related domains are tightly integrated within Google's ecosystem, enhancing service cohesion. Growth indicators include continuous product updates and integration with emerging technologies like generative AI. Strategic observations suggest maintaining strong security transparency and expanding incident response visibility to enhance customer trust.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of Google-managed certificates, and implied security headers such as Content-Security-Policy and X-Frame-Options. No sensitive data exposure or vulnerable libraries were detected in the HTML content. Privacy and cookie policies comply with GDPR, and cookie consent mechanisms are implemented. However, the absence of a dedicated security policy page, vulnerability disclosure, or security.txt file limits transparency. Incident response contact information is not publicly available, which could be improved. Overall, the security practices align with enterprise standards, but enhancing public security documentation would strengthen trust and compliance.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and practices.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file.
  3. Provide clear incident response contact channels for security issues.
  4. Enhance transparency around data retention and privacy compliance specifics.
  5. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using a modern technology stack including Google Fonts, Material Icons, and Firebase-specific JavaScript libraries. It leverages Google Cloud Platform for hosting, ensuring fast load times and high availability. The site is mobile-optimized with responsive design and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The use of Google Analytics and Tag Manager indicates moderate user tracking with consent. Technical risks are minimal, with no visible deprecated or vulnerable components. Opportunities exist to improve technical documentation and security transparency to further reduce operational risks.
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.
