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

The analyzed website is the Google Accounts sign-in page, a critical component of Google's identity and access management infrastructure. It serves as the authentication gateway for users accessing various Google services and third-party applications via OAuth 2.0. The page is professionally designed, highly secure, and optimized for performance and accessibility, reflecting Google's enterprise-grade technology platform. The business behind the site is Google LLC, a subsidiary of Alphabet Inc., a global technology leader with a strong market position in digital services and cloud infrastructure. Technically, the site leverages modern web technologies, including JavaScript, OAuth 2.0 with PKCE, and Google APIs, hosted on Google Cloud Platform. It employs robust security measures such as HTTPS enforcement, security headers, and content security policies, ensuring a secure user authentication experience. The site is mobile-optimized and accessible, providing a seamless user experience across devices. From a security perspective, the site demonstrates excellent practices with no detected vulnerabilities or exposed sensitive data. Privacy compliance is moderate on this page, as it is primarily a login interface; detailed privacy and cookie policies reside on the main google.com domain. No contact or incident response information is present on this page, which is typical for such service endpoints. Overall, the site is highly trustworthy, safe for general audiences, and integral to Google's service ecosystem. Strategic recommendations include maintaining up-to-date security practices, enhancing privacy disclosures on related domains, and continuous monitoring for emerging threats to preserve user trust and compliance.

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

3 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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

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 notes

Notes

The website is built on a robust technical infrastructure leveraging Google's proprietary frameworks and APIs. It uses modern JavaScript and OAuth 2.0 protocols to facilitate secure user authentication. Hosting on Google Cloud Platform ensures high availability and performance. The page is optimized for fast loading and mobile responsiveness, with accessibility considerations implemented. No CMS or third-party content management systems were detected, indicating a custom-built solution. The technical implementation aligns with best practices for security, performance, and user experience, minimizing technical debt and supporting scalability.
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.
