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

5 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • 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

  3. 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

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

Vercel operates in the technology sector, focusing on platform-as-a-service offerings for web development. Their business model centers on providing tools that streamline deployment workflows and preview environments, targeting developers and software teams. The company benefits from a strong brand, long domain history, and a consistent digital presence. Customer testimonials and privacy compliance enhance trust. The absence of direct contact emails or phone numbers suggests a preference for managed communication channels via forms. The use of advanced analytics and tracking tools like Sift indicates a mature marketing and fraud prevention strategy. Vercel's ecosystem is tightly integrated with popular version control systems and CI/CD pipelines, reinforcing its competitive advantage.

Security posture

The website exhibits a mature security posture with enforced HTTPS, multiple security headers, and client-side scripts designed to prevent abuse and automate challenge-response mechanisms. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the lack of a dedicated security policy or incident response page limits transparency for security researchers and customers. The cookie consent mechanism and privacy policy align with GDPR requirements, indicating compliance awareness. Recommendations include publishing a security.txt file and incident response contacts to improve security communication and vulnerability disclosure. Overall, the security measures are robust but could benefit from enhanced transparency.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  3. Provide explicit contact channels for security incidents, such as security@ or abuse@ email addresses.
  4. Regularly review and audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance documentation on certifications and compliance frameworks to build customer trust.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on Vercel's own platform, ensuring optimized performance and scalability. The use of Tailwind CSS contributes to a consistent and responsive design. The site includes advanced client-side scripts for security and analytics, including challenge-response mechanisms and integration with Sift for fraud detection. Performance is fast with preloading of critical assets and optimized images. Accessibility features are present but could be further enhanced with explicit ARIA roles and landmarks. SEO is well addressed with comprehensive meta tags and Open Graph data. Overall, the technical infrastructure is modern, robust, and aligned with best practices for developer-focused platforms.
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.
