Security score

83/100

Risk levelLow

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

The analyzed URL is a Google accounts sign-in page used for OAuth authentication, specifically scoped for the domain airbnb.com. This page is part of Google's identity services infrastructure and is designed to securely authenticate users. The content is heavily scripted and served via Google's secure infrastructure, with no direct business content or marketing information present. Due to the nature of the page and Google's security measures, the content is partially inaccessible or truncated, limiting detailed analysis. The domain accounts.google.com is a subdomain of google.com, a globally recognized and trusted entity. The WHOIS data for this subdomain is not publicly available, which is standard practice for subdomains under large organizations. The page uses HTTPS and modern web technologies to ensure secure user authentication.

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. 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

  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

This page serves as a critical authentication gateway for users accessing services that rely on Google accounts for identity verification, such as Airbnb in this case. It does not represent a standalone business but is a service component of Google. The business model behind this service is to provide secure, scalable identity management and authentication services to third-party applications. The target audience includes users of Google accounts and partner services requiring OAuth authentication. The page itself does not contain commercial content, revenue streams, or direct customer engagement features.

Security posture

The page is served over HTTPS with strong security headers implied by Google's infrastructure, although explicit headers could not be extracted due to content truncation. The use of OAuth 2.0 with PKCE (Proof Key for Code Exchange) indicates adherence to modern secure authentication standards. No vulnerabilities or exposed sensitive data were detected in the accessible content. The page is likely protected by Google's advanced security mechanisms including anti-bot and WAF protections, which restrict automated access and scraping. No privacy or cookie policies were directly found on this page, but these are typically linked on Google's main domains. Overall, the security posture is strong but limited visibility prevents full assessment.

Recommendations

  1. For full security and compliance assessment, access to complete page content and HTTP headers is necessary.
  2. Verify presence and accessibility of privacy and cookie policies on related Google domains.
  3. Ensure OAuth implementations follow best practices including secure redirect URIs and scope limitations.
  4. Monitor for any changes in WHOIS or domain registration data that could indicate security risks.
  5. Maintain awareness of Google's security advisories related to accounts and authentication services.
Site observations

Automated reading of the public site. Ratings are indicative.

Generic detected. The WHOIS query returned no match for the domain, and the HTML content is truncated and minimal, indicating possible access restrictions or WAF/security challenge. The page is a Google accounts sign-in page which is typically protected and not fully accessible for scraping. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Analytics and tracking

Site quality

Key observations

  1. The URL is a Google accounts sign-in page for OAuth authentication.
  2. The WHOIS lookup for the subdomain accounts.google.com returned no match, which is expected for subdomains.
  3. The HTML content is truncated and appears to be a standard Google sign-in page with heavy JavaScript and CSS.
  4. No privacy policy, cookie policy, or terms of service links were found in the provided content snippet.
  5. No contact information such as emails or phone numbers were found in the content.
  6. No external advertising or tracking scripts were identified in the truncated content.
  7. The page uses HTTPS and is served by Google infrastructure.
  8. The page is likely behind Google's security and anti-bot mechanisms, limiting full content access.
  9. No business-specific information is present as this is a service page for Google accounts.
  10. Content safety is high as this is a standard authentication page with no adult or questionable content.
Technical notes

Notes

The page uses a complex JavaScript-driven UI with Google’s proprietary libraries and frameworks for identity management. It employs OAuth 2.0 with PKCE for secure authorization code flow. The hosting is on Google’s global infrastructure, ensuring high availability and performance. The page is optimized for modern browsers and likely mobile responsive, although this could not be fully verified due to content truncation. No CMS or third-party hosting providers are involved. The technical stack is modern and robust, designed for secure authentication workflows.
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.
