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

The AI SDK website is a professional and well-structured platform offering an open-source AI toolkit for TypeScript developers, created by Vercel, Inc., the company behind Next.js. It targets developers seeking to integrate AI capabilities into their applications with ease, providing a unified API and generative UI components. The site demonstrates a modern technical infrastructure leveraging Next.js, React, and Vercel hosting, ensuring fast performance and excellent mobile optimization. Security posture is strong with HTTPS and appropriate security headers, though explicit privacy and cookie policies are absent, which is a compliance gap. Overall, the website reflects a mature, credible technology product with strong branding and trust signals but would benefit from enhanced privacy and compliance disclosures.

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

7 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. 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';…

  3. 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

  • 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 positions the AI SDK as a key enabler for AI-powered product development, leveraging its reputation from Next.js. The business model revolves around open-source software with integrations to major AI providers like OpenAI, Claude, and Hugging Face, appealing to a developer audience. The partnership ecosystem includes GitHub for source code hosting and Vercel for deployment. The site’s content and branding indicate a medium-sized technology company with a focus on developer tools and AI innovation. Growth indicators include recent product announcements and active community engagement via playgrounds and cookbooks.

Security posture

The website exhibits a high security maturity level with enforced HTTPS, comprehensive security headers, and no visible vulnerabilities or exposed sensitive data. However, it lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for transparency and compliance. GDPR compliance is not clearly addressed, and no data protection officer contact is provided. The absence of privacy and cookie policies represents a compliance risk. Overall, the security posture is strong technically but could improve in governance and compliance documentation.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Provide clear contact information for security incidents and data protection inquiries.
  4. Add cookie consent mechanisms to comply with privacy regulations.
  5. Enhance transparency on data collection, retention, and user privacy practices.

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.
