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

Cursor operates in the competitive AI developer tools market, leveraging frontier AI models to deliver smart coding assistance. Its business model includes downloadable software for multiple platforms and enterprise solutions, targeting professional developers and organizations. The company has established credibility through SOC 2 certification and endorsements from notable tech companies like OpenAI, Google, and Figma. The partnership with Anysphere and active presence on GitHub, Twitter, and Discord indicate a strong developer community engagement. Growth indicators include frequent feature updates and a focus on privacy options, positioning Cursor as a premium AI coding assistant with a focus on security and user trust.

Security posture

Cursor demonstrates a mature security posture with HTTPS enforced, domain transfer lock, and SOC 2 certification indicating strong internal controls. The option for Privacy Mode to avoid remote code storage is a significant privacy feature. However, the absence of DNSSEC reduces DNS security, and no public security policy or incident response contact is provided, which are gaps in transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the analysis. The site uses modern frameworks and hosting providers with good security reputations. Overall, the security maturity is good but could be improved with published policies and DNSSEC.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements and consent mechanisms.
  3. Add a public security policy and incident response contact information to improve transparency and trust.
  4. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Consider adding phone and physical address contact details to enhance business credibility.

Technical notes

Notes

The website is built using Next.js, a modern React framework, and hosted on Vercel, ensuring fast performance and scalability. It uses Vercel Analytics and Speed Insights for monitoring. The site is mobile-optimized with responsive design and accessibility considerations. The domain is registered with NameCheap and has a long history, supporting legitimacy. No CMS was detected, indicating a custom or framework-based site. The tech stack and hosting choices reflect a modern, well-maintained infrastructure with good performance and SEO optimization. Technical risks are minimal, but enabling DNSSEC and publishing security documentation would strengthen the overall posture.
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.
