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, providing a platform-as-a-service model focused on frontend developers and product teams. Their business model leverages serverless infrastructure, AI-powered tools, and global CDN capabilities to deliver fast, scalable web applications. The company has a strong market position with a large enterprise footprint and a long-established domain. Their ecosystem includes partnerships and integrations with AI SDKs and developer tools. Growth indicators include recent funding rounds and product expansions into AI and observability. The blog content reflects strategic communication to developers and customers, reinforcing brand authority and technical leadership.

Security posture

The website exhibits a solid security foundation with HTTPS and domain status locks preventing unauthorized changes. However, DNSSEC is not enabled, which could enhance DNS security. No explicit security policies or incident response contacts are published on the blog page, representing a compliance gap. The site uses bot detection scripts and internal analytics to monitor traffic and potential abuse. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is good but could be improved with more transparent policies and DNS security enhancements.

Recommendations

  1. Enable DNSSEC to strengthen DNS integrity and prevent spoofing.
  2. Publish clear privacy and cookie policies with user consent mechanisms to improve compliance.
  3. Add a dedicated security policy and incident response contact information to enhance transparency.
  4. Implement and publicize a vulnerability disclosure program to encourage responsible reporting.
  5. Regularly review and update third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js, leveraging Vercel's own hosting platform for optimized performance. The use of Tailwind CSS and modular JavaScript chunks indicates a well-structured frontend architecture. Performance is fast with good mobile responsiveness and accessibility features. SEO is supported by comprehensive meta tags and Open Graph data. The site uses custom analytics and fraud detection scripts, reflecting a mature approach to user monitoring. Technical risks are minimal, with no outdated or vulnerable libraries detected. Opportunities exist to enhance DNS security and formalize privacy and security documentation.
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.
