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

Vercel is a well-established technology company founded in 1999, specializing in providing developers with frameworks, workflows, and cloud infrastructure to build and deploy fast, personalized web experiences. Positioned as a leading platform in the web development and cloud deployment space, Vercel targets developers and businesses seeking efficient and scalable web solutions. The website reflects a high level of professionalism with excellent design quality, clear navigation, and mobile optimization, leveraging modern technologies such as Next.js and React hosted on the Vercel platform itself. From a technical perspective, the site employs a modern tech stack with performance and SEO optimizations, including Vercel's own analytics and speed insights tools. Security posture is strong with HTTPS enforced and domain registration protections in place, although DNSSEC is not enabled, representing a minor security improvement opportunity. The site uses challenge mechanisms on sensitive API endpoints to mitigate abuse. Security-wise, while the site demonstrates good practices, it lacks visible privacy and cookie policies and explicit contact information for incident response, which are important for compliance and trust. No vulnerabilities or exposed sensitive data were detected. The domain WHOIS data is consistent with a legitimate business, showing a long registration history and domain status flags that prevent unauthorized changes. Overall, Vercel's website is secure, professional, and technically mature, but could improve privacy compliance and transparency by publishing clear policies and contact details. Strategic recommendations include enabling DNSSEC, adding privacy and cookie policies with consent mechanisms, publishing a vulnerability disclosure policy, and providing clear security incident contacts.

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 as a Platform as a Service (PaaS) provider in the technology sector, focusing on web development and deployment. Its competitive advantage lies in integrating developer tools with cloud infrastructure optimized for frontend frameworks, particularly Next.js. Revenue streams likely include subscription plans and enterprise services. The target customer segments are developers, startups, and enterprises seeking scalable web deployment solutions. The company shows growth indicators through advanced analytics and AI cloud integration. The partnership ecosystem includes integrations with major cloud providers and developer tools. Operationally, Vercel maintains a strong market presence with a focus on developer experience and performance.

Security posture

The security maturity of Vercel's website is good, with HTTPS enforced and domain registration protections such as clientDeleteProhibited and clientTransferProhibited statuses. The site employs JavaScript-based challenge mechanisms on sensitive POST API endpoints to mitigate abuse. However, the absence of DNSSEC is a minor gap. There is no visible security policy or incident response information, which limits transparency and readiness perception. No exposed sensitive data or vulnerable libraries were detected. Compliance with GDPR and other privacy regulations is not clearly demonstrated due to missing privacy and cookie policies. Overall, the security posture is strong but could benefit from enhanced policy disclosures and DNS security improvements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with explicit consent mechanisms to improve GDPR compliance.
  3. Create and display a clear security policy and incident response contact information to enhance transparency and trust.
  4. Implement and publish a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  5. Provide visible company contact information including emails and phone numbers for support and security inquiries.

Technical notes

Notes

The website is built on a modern and robust technical infrastructure using Next.js and React frameworks, hosted on the Vercel cloud platform. It employs Tailwind CSS for styling and integrates Vercel Analytics and Speed Insights for performance monitoring. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. JavaScript challenge scripts protect sensitive API endpoints. The domain is registered with Amazon Registrar, Inc. and secured with prohibitive domain statuses. The absence of DNSSEC is a minor technical debt. Overall, the technical implementation supports fast, scalable, and secure web delivery with opportunities for further security enhancements.
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.
