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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Microsoft's Visual Studio website reflects a mature enterprise-level digital presence with strong branding consistency and trust indicators. The platform targets professional developers and teams, offering a broad range of development tools and services. The company leverages advanced analytics and marketing tools to optimize user engagement and performance. The absence of direct contact information on the homepage suggests a focus on self-service and digital engagement. The domain is a subdomain of microsoft.com, reinforcing its legitimacy and corporate backing. The site supports multiple languages, indicating a global market reach.

Security posture

The website demonstrates a strong security posture with HTTPS enforced, comprehensive security headers, and the use of monitoring tools such as New Relic and Microsoft Clarity. Cookie consent mechanisms comply with GDPR requirements, enhancing privacy compliance. However, explicit security policies, incident response contacts, and vulnerability disclosure information are not publicly visible, representing areas for improvement. No vulnerabilities or suspicious domains were detected. Overall, the site aligns well with best practices for enterprise web security.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Provide clear security contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance data retention policy disclosures to align with privacy best practices.
  5. Regularly review and audit third-party scripts and analytics tools for security risks.

Technical notes

Notes

The website is built on WordPress using the Avada theme and Fusion Builder, integrating Microsoft-specific plugins and styles. It employs modern web technologies including JavaScript, jQuery, CSS3, and JSON-LD structured data for SEO. Hosting and analytics are managed via Microsoft Azure and New Relic, ensuring robust performance and monitoring. The site is fast, mobile-optimized, and accessible, with strong SEO practices evident in meta tags and structured data. Technical risks are minimal, but continuous monitoring of third-party dependencies is advised to mitigate potential vulnerabilities.
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.
