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

1 finding 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"

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 Teams Free Meetings is positioned as a leading free collaboration tool within the technology sector, targeting a broad audience from individuals to small organizations. The business model supports free usage likely as a gateway to Microsoft’s paid services. The platform's competitive advantage lies in its integration with Microsoft 365 and Skype, extensive feature set, and global brand recognition. The website reflects a mature digital presence with strong branding consistency and trust signals. The absence of direct contact information on this subdomain is typical for large enterprises that centralize support elsewhere. The partnership ecosystem includes Microsoft’s own domains and services, ensuring a controlled and secure environment.

Security posture

The security maturity of the website is high, with HTTPS enforced and secure authentication via Microsoft Online login. Input validation is implemented on forms, and a cookie consent mechanism is present, supporting privacy compliance. However, no explicit security headers (e.g., CSP, HSTS) were detected in the provided data, and no public security policy or incident response contacts are available on this subdomain. No vulnerabilities or exposed sensitive data were found. The site would benefit from publishing security policies and providing clear incident response channels to enhance transparency and trust further.

Recommendations

  1. Implement and verify security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen security posture.
  2. Publish a dedicated security policy and incident response information accessible from the site to improve transparency and user trust.
  3. Provide clear contact channels for security incidents, such as security@ or abuse@ email addresses.
  4. Continue maintaining comprehensive privacy and cookie policies with clear user consent mechanisms.
  5. Enhance analytics and tracking transparency by disclosing data collection and retention policies explicitly.

Technical notes

Notes

The website uses a modern technology stack including HTML5, CSS3, JavaScript with Webpack and RSPack bundler, and is hosted on Microsoft’s CDN infrastructure. It integrates OAuth2 authentication via Microsoft Online login iframe. The site is optimized for performance and mobile devices, with good accessibility features and SEO meta tags. No CMS was detected, suggesting a custom or proprietary platform. The technical implementation is robust, with no visible technical debt or performance issues. Opportunities exist to enhance security headers and publish more detailed technical and security documentation.
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.
