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 under Google LLC, targeting individual bloggers and content creators globally. Its business model is based on providing free blog hosting and tools, monetized primarily through Google AdSense advertising. The platform benefits from Google's extensive ecosystem, including integration with Google Analytics and domain registration services. Blogger.com holds a strong market position as one of the earliest and most recognized blogging services, with a large user base and consistent branding. The absence of explicit contact and policy documents on the analyzed page suggests these may be located elsewhere or require better visibility. The platform's partnership ecosystem is tightly integrated within Google services, enhancing user convenience and trust.

Security posture

Blogger.com exhibits a robust security posture with enforced HTTPS, excellent SSL configuration, and comprehensive security headers such as Content-Security-Policy and Strict-Transport-Security. The site avoids exposing sensitive information in its HTML content and uses secure form practices with nonce attributes. No vulnerable libraries or security misconfigurations were identified. However, the lack of explicit security policy documentation and incident response contact details represents a compliance gap. The platform appears ready for incident response but could improve transparency by publishing these details. Overall, Blogger.com aligns well with industry best practices, minimizing risk exposure for users and the business.

Recommendations

  1. Publish explicit privacy and cookie policies prominently linked on the about or footer pages.
  2. Implement and disclose a vulnerability disclosure policy and security incident response contacts.
  3. Add clear contact information for security and abuse reporting to enhance trust and compliance.
  4. Ensure cookie consent mechanisms are in place to comply with GDPR and other privacy regulations.
  5. Maintain continuous monitoring of third-party libraries and update them to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a modern, scalable infrastructure hosted by Google, utilizing HTML5, CSS3, and JavaScript with Google Fonts for typography. The use of Google Cloud hosting ensures fast load times and high availability. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. SEO is supported by comprehensive meta tags including Open Graph and Twitter Cards. No CMS is detected, indicating a custom-built platform. The technical implementation reflects a mature and well-maintained digital presence with minimal technical debt and strong performance characteristics.
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.
