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

Vercel is a leading technology company specializing in frontend cloud infrastructure and developer tools that enable fast, scalable, and secure web experiences. Their platform integrates seamlessly with popular frameworks like Next.js and React, providing Git-connected deploys, AI-powered applications, and managed infrastructure. Vercel targets developers, platform engineers, design engineers, and enterprises, positioning itself as a key player in the frontend cloud market. Technically, Vercel employs modern technologies including Next.js, React, and TypeScript, hosted on their own Vercel platform with edge functions and a global CDN. The website demonstrates excellent design, mobile optimization, and SEO practices, reflecting a mature digital presence. However, the SSL certificate is currently invalid, and TLS 1.2+ protocols are not supported, which impacts the security posture. Security-wise, the site implements multiple security headers such as CSP, X-Frame-Options, and others, but lacks a valid SSL certificate and HSTS enforcement. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is good with a comprehensive privacy policy, though no cookie consent mechanism was found. Contact information is available primarily via contact forms. Overall, Vercel presents a high-quality, professional, and trustworthy web presence with minor security and privacy compliance gaps. Strategic improvements in SSL management and cookie consent would enhance their security and compliance posture.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

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

  • Security headers: did not complete in this scan.
  • 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 cloud-based frontend deployment and developer tools. Their business model revolves around providing a platform-as-a-service (PaaS) that accelerates web development and deployment. They serve a broad developer audience including enterprises, offering scalable and secure infrastructure. The company maintains strong partnerships with analytics, security, and marketing service providers, enhancing their ecosystem. Their market position is strong, supported by a comprehensive suite of services and a professional, content-rich website that highlights customer success stories and integrations.

Security posture

The website exhibits a moderate security maturity level with several best practices in place, including a robust Content-Security-Policy and other security headers. However, the absence of a valid SSL certificate and lack of TLS 1.2+ support are significant weaknesses. No signs of malware, phishing, or exposed credentials were found. The site lacks a cookie consent mechanism, which is a compliance gap. Incident response and vulnerability disclosure information are not explicitly provided. Overall, the security posture is good but requires attention to SSL/TLS and privacy compliance enhancements.

Recommendations

  1. Obtain and maintain a valid SSL certificate with support for TLS 1.2 or higher to ensure secure communications.
  2. Enable and configure HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options.
  3. Implement a comprehensive cookie policy and user consent mechanism to enhance privacy compliance.
  4. Publish explicit vulnerability disclosure and incident response policies to improve security transparency.
  5. Regularly review and tighten Content-Security-Policy to minimize use of unsafe directives.
Technical notes

Notes

Vercel's website is built using modern web technologies including Next.js, React, and TypeScript, hosted on the Vercel platform. The site is well-structured with extensive use of CSS and JavaScript chunks for performance optimization. It features responsive design, accessibility considerations, and SEO-friendly metadata. Performance is fast, supported by a global CDN and edge network. Technical risks include the invalid SSL certificate and lack of advanced TLS protocol support, which should be addressed to avoid security warnings and ensure user trust.
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.
