0–100, higher is better. How it is calculated

Blogger.com is a well-established blogging platform owned by Google LLC, offering users the ability to create unique and beautiful blogs easily. The platform targets individuals and content creators who want to publish their passions and monetize their content through Google AdSense. The website demonstrates a professional design with consistent branding and integrates seamlessly with Google services such as Google Analytics and custom domain purchases. Technically, the site uses modern web technologies including HTML5, CSS3, JavaScript, and Google Fonts, hosted on Google Cloud infrastructure, ensuring fast performance and excellent mobile optimization. Security-wise, the site enforces HTTPS and follows good practices, although explicit security headers and privacy policies are not evident in the provided content. The WHOIS data is unavailable or privacy protected, which is typical for Google domains and does not detract from the site's legitimacy. Overall, the site is safe, trustworthy, and professionally maintained, though improvements in privacy transparency and security header implementation are recommended.

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"

  2. 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

    • 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 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

Blogger.com operates as a free blogging platform with monetization options via Google AdSense, positioning itself as a key player in the content creation and publishing market. Its competitive advantage lies in Google’s brand trust, integration with Google services, and ease of use. The business model focuses on attracting individual bloggers and small content creators, providing them with tools to customize their blogs and earn revenue. The platform's enterprise scale and global reach are supported by Google’s infrastructure. The absence of explicit contact information and privacy policies in the analyzed content suggests a reliance on Google's broader corporate policies. Strategic partnerships are primarily internal within Google's ecosystem. Growth indicators include continuous updates to templates and analytics features, catering to evolving user needs.

Security posture

The security posture of Blogger.com is strong in terms of HTTPS enforcement and absence of visible vulnerabilities or exposed sensitive data. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and others in the provided HTML snippet indicates room for enhancement. No incident response or vulnerability disclosure information is present, which could be improved to align with best practices. Privacy compliance indicators such as GDPR adherence and cookie consent mechanisms are not evident, representing a compliance gap. The site's association with Google provides a high baseline of security culture and incident response readiness, but explicit public documentation would strengthen user trust and regulatory compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear GDPR compliance and consent mechanisms.
  2. Add security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide explicit contact information for support and security incident reporting, including a vulnerability disclosure policy or security.txt file.
  4. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  5. Enhance transparency around data protection officers and certifications to improve user trust and compliance posture.

Technical notes

Notes

The website is built on a robust technical infrastructure leveraging Google Cloud Platform, with a modern tech stack including HTML5, CSS3, JavaScript, and Google Fonts. The site demonstrates excellent mobile responsiveness and accessibility features, contributing to a positive user experience. Performance is optimized with fast loading times and efficient resource usage. The CMS is a proprietary Google Blogger platform, tightly integrated with Google services such as AdSense and Analytics. No technical debt or outdated technologies were detected in the provided content. Opportunities exist to improve security header implementation and formalize privacy and compliance documentation to reduce technical and regulatory 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.
