Security score

78/100

Risk levelLow

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

Microsoft OneNote is a digital note-taking application integrated within the Microsoft ecosystem, targeting general users seeking productivity tools across devices. The website analyzed is primarily a login page facilitating user authentication via Microsoft accounts, leveraging OAuth 2.0 and Microsoft authentication services. The technical infrastructure is modern, using standard web technologies such as jQuery and SVG animations, hosted likely on Microsoft Azure infrastructure. Security posture is solid due to integration with Microsoft's authentication platform, though explicit security headers and privacy policies are not present on this login page. Overall, the site is trustworthy and professional but could improve transparency on privacy and cookie policies. The domain WHOIS data is unavailable, likely due to privacy or registry restrictions, but the domain's association with Microsoft and its ecosystem strongly supports legitimacy.

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

4 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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 appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Microsoft OneNote operates as part of Microsoft's productivity software suite, serving a broad market of individual and enterprise users. Its business model is SaaS-based, integrated with cloud services for synchronization and collaboration. The product benefits from Microsoft's strong market position and brand recognition. The login page analyzed is a critical access point for users, linking to Microsoft's authentication services, indicating a tightly coupled ecosystem. The absence of direct contact or policy links on this page suggests a focus on streamlined user access rather than customer support or legal disclosures at this stage. Partnerships are primarily internal within Microsoft domains, ensuring secure and consistent user experience.

Security posture

The security posture of the site is robust in terms of authentication mechanisms, utilizing Microsoft's OAuth 2.0 and login.live.com services. However, the analyzed page lacks explicit security headers in the provided data, which could be improved to enhance protection against common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected. The absence of privacy and cookie policies on this page is a compliance gap, especially for GDPR and similar regulations. Incident response and security policy information are not present, limiting transparency. Overall, the site benefits from Microsoft's enterprise-grade security infrastructure but could improve front-facing security disclosures and headers.

Recommendations

  1. Add explicit links to privacy and cookie policies on the login page to improve compliance and user trust.
  2. Implement and verify security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  3. Enhance accessibility and SEO features to improve user experience and discoverability.
  4. Provide visible contact or support information related to security incidents or data protection inquiries.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern tech stack including jQuery 3.5.0 and bodymovin for SVG animations, integrated with Microsoft authentication services via OAuth 2.0. Hosting is likely on Microsoft Azure, inferred from domain and service URLs. The page is lightweight with minimal content focused on login redirection and animation. Performance is moderate with room for improvement in mobile optimization and accessibility. No CMS or third-party analytics scripts were detected on this page, indicating a minimalistic approach for the login interface. The technical implementation aligns with enterprise standards but could benefit from enhanced SEO and accessibility compliance.
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.
