Low risk. 1 critical or high finding in SSL/TLS.
Visual Studio, hosted at visualstudio.microsoft.com, is a flagship product of Microsoft Corporation, a leading global technology enterprise. The website offers comprehensive developer tools including an Integrated Development Environment (IDE) and code editor, targeting software developers across platforms and languages. Microsoft’s market position as a dominant technology provider is reinforced by the professional presentation and extensive service offerings visible on the site. The business model centers on providing software development tools and cloud integration services to a broad developer audience worldwide. Technically, the website is built on WordPress with the Avada theme and leverages modern web technologies such as jQuery, New Relic for performance monitoring, Microsoft Clarity for user behavior analytics, and Adobe Target for marketing optimization. The site is hosted likely on Microsoft Azure infrastructure, ensuring robust performance, excellent mobile optimization, and good accessibility standards. SEO and metadata are well implemented, including Open Graph and JSON-LD structured data for enhanced search engine visibility. From a security perspective, the site enforces HTTPS with strong SSL configuration and includes multiple security headers to protect against common web vulnerabilities. Privacy compliance is robust, featuring a clear privacy policy, cookie consent mechanisms, and GDPR adherence. However, explicit security policies, incident response information, and vulnerability disclosure mechanisms are not publicly evident, representing areas for improvement. Overall, the website reflects a mature, secure, and professional digital presence consistent with Microsoft’s reputation. The absence of WHOIS data for the subdomain is expected and does not detract from legitimacy. Strategic recommendations include publishing explicit security and incident response policies, adding vulnerability disclosure information, and enhancing direct security contact channels to further strengthen trust and compliance.
Scanned
NIS2 Art. 21(2)
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.
1 finding rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
SSL certificate uses 256-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
