0–100, higher is better. How it is calculated

Vercel is a well-established technology company founded in 1999, providing a cloud platform and developer tools to build, deploy, and scale modern web experiences. The company targets developers and businesses seeking fast, scalable, and secure web deployment solutions. Their market position is strong as a leading platform in the frontend development ecosystem, offering key services such as Git-connected deploys, cloud infrastructure, and AI-enhanced workflows. Technically, the website is built using modern frameworks like React and Next.js, hosted on Vercel's own cloud platform. The site demonstrates excellent performance, mobile optimization, and SEO practices. Security measures include HTTPS enforcement, domain registration protections, and client-side security SDKs to validate requests and protect APIs. However, the site lacks explicit privacy, cookie, and security policies, which impacts privacy compliance scores. No direct contact information or incident response channels are published, limiting transparency in security and compliance. The domain registration data is consistent and trustworthy, supporting the legitimacy of the business. Overall, Vercel's website is professional, secure, and technically mature but would benefit from enhanced privacy compliance documentation and published security policies to improve trust and regulatory adherence.

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

3 findings rated critical or high. Fix these first.

  1. 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

  2. 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 as a platform-as-a-service provider focused on web deployment and developer tools. Their business model revolves around providing scalable cloud infrastructure and seamless developer workflows, targeting frontend developers and enterprises. The company benefits from a strong brand presence, consistent messaging, and a modern digital ecosystem. Partnerships and integrations with major code repositories and analytics providers enhance their market reach. Growth indicators include advanced AI cloud capabilities and event marketing such as Ship AI. The absence of explicit contact details suggests a focus on digital self-service and enterprise sales channels.

Security posture

The security posture of Vercel's website is solid, with HTTPS enforced and domain registration protections in place. The use of a client-side security SDK to protect sensitive API endpoints indicates proactive security measures. However, the lack of published security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. No security headers were explicitly detected in the provided data, and DNSSEC is not enabled, which could be improved. Overall, the site demonstrates good security hygiene but should enhance transparency and formalize security governance documentation.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  3. Provide a dedicated security policy page including incident response contacts and vulnerability disclosure guidelines.
  4. Implement and document security headers such as Content-Security-Policy and X-Frame-Options.
  5. Enhance transparency by publishing contact information for data protection officers or security teams.

Technical notes

Notes

The website leverages a modern technology stack including React and Next.js, optimized for performance and mobile responsiveness. Hosting on Vercel's own cloud platform ensures fast delivery and scalability. The site uses advanced client-side scripting for security and analytics, including integration with Sift for fraud detection. The technical implementation is robust with good SEO and accessibility features. Opportunities exist to improve technical security configurations such as DNSSEC and security headers. The site shows no signs of technical debt or outdated libraries in the analyzed content.
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.
