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

2 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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 maintains a dominant market position in productivity and cloud services, with www.office.com acting as a critical access point for its Microsoft 365 offerings. The business model is subscription-based, targeting enterprises, SMBs, and consumers worldwide. The site integrates with a broad ecosystem of Microsoft services and partners, enhancing user engagement and retention. The absence of direct contact information on the landing page is typical for large enterprises relying on centralized support channels. The branding is consistent and leverages Microsoft's global reputation. The site supports Microsoft's strategic focus on cloud adoption and AI-enhanced productivity tools, such as Microsoft 365 Copilot.

Security posture

The website exhibits a mature security posture with enforced HTTPS, strong security headers, and no exposed sensitive data in the HTML content. The presence of Azure monitoring scripts indicates active telemetry and security monitoring. Cookie consent mechanisms comply with privacy regulations, enhancing user trust. No signs of outdated or vulnerable libraries were found. The lack of publicly listed incident response or security policy pages is common for large enterprises that centralize such information elsewhere. Overall, the security controls are appropriate for a high-profile enterprise website.

Recommendations

  1. Maintain continuous security monitoring and timely patching of all web components.
  2. Consider publishing a dedicated security policy and incident response contact page for transparency.
  3. Enhance visibility of business contact information for improved customer support access.
  4. Regularly review third-party scripts and tracking technologies for privacy compliance.
  5. Continue investment in accessibility and mobile optimization to maintain excellent user experience.

Technical notes

Notes

The site uses a modern tech stack including JavaScript, CSS, and HTML5, served via Microsoft Azure CDN for optimal performance. Fonts and assets are loaded securely with integrity checks. The site is mobile-optimized and accessible, with semantic HTML and ARIA attributes. Analytics and monitoring are implemented through Azure scripts, supporting operational insights. No CMS was explicitly detected, suggesting a custom or proprietary Microsoft framework. Performance is fast with minimal blocking resources. The technical implementation aligns with enterprise best practices, 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.
