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 a platform-as-a-service business model targeting frontend developers and enterprises seeking scalable web infrastructure. Their competitive advantage lies in seamless integration with modern web frameworks and AI tooling, supported by a strong developer community and strategic partnerships such as with Solara6 and NuxtLabs. Revenue streams likely include subscription plans for cloud services and enterprise offerings. The company demonstrates growth through continuous innovation in AI and serverless compute, positioning itself as a key player in the evolving frontend cloud market. The blog content reflects a strategic emphasis on AI-driven development and infrastructure efficiency, reinforcing Vercel's market differentiation.

Security posture

The website exhibits a mature security posture with HTTPS enforced and client-side bot detection scripts protecting critical API endpoints. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and compliance. DNSSEC is not enabled, which could enhance DNS security. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is strong but could be elevated by formalizing and publishing security governance documents and enhancing header configurations.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  3. Develop and make publicly available security policies and incident response procedures to enhance transparency and trust.
  4. Implement a formal vulnerability disclosure program and security.txt file to encourage responsible reporting.
  5. Explicitly configure and verify security headers such as Content-Security-Policy and X-Content-Type-Options to harden the website.

Technical notes

Notes

The website is built on a modern, performant tech stack including Next.js and React, with Tailwind CSS for styling. Hosting on Vercel's platform ensures fast load times and excellent mobile optimization. The use of custom CMS and asset management indicates a mature content infrastructure. Analytics and tracking are implemented primarily through Vercel's own tools and Sift for fraud detection, balancing insight with privacy. The technical implementation is robust with good SEO and accessibility features, though explicit security headers and privacy compliance mechanisms could be improved. Overall, the technical foundation supports a scalable and secure web presence aligned with enterprise standards.
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.
