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

Uploadthing.com is a technology startup founded in 2023 that provides an easier way to upload files, targeting developers and businesses needing file upload infrastructure. The website is built using modern technologies such as React, Next.js, and Tailwind CSS, hosted on Vercel, indicating a mature and performant technical infrastructure. Security posture is adequate with HTTPS enabled and domain status OK, but lacks advanced DNS security features like DNSSEC and security headers. Privacy and compliance documentation such as privacy policy, cookie policy, and terms of service are not found, which is a gap for GDPR and other regulations. Overall, the site is professional and trustworthy but would benefit from enhanced compliance and security 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

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"

  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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  4. 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

The company operates in the technology sector, offering SaaS solutions for file uploads. Its business model focuses on providing developer-friendly APIs and integrations for file management. The market position is emerging with a focus on ease of use and integration. The target audience includes developers and businesses requiring reliable file upload services. The domain age and registration details align with the startup nature of the business. No parent or subsidiary companies are identified. The website branding is consistent and content quality is good, supporting a positive market presence.

Security posture

The website uses HTTPS with a valid SSL certificate and is hosted on a reputable platform (Vercel). However, DNSSEC is not enabled, and no security headers were detected in the HTML content, which could expose the site to certain attacks. There is no visible vulnerability disclosure or incident response information, which limits transparency in security practices. No sensitive data exposure or vulnerable libraries were detected in the provided content. The security score is moderate, with recommendations to improve DNS security, implement security headers, and publish security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and other privacy regulations.
  4. Add a vulnerability disclosure policy or security.txt file to improve transparency and encourage responsible reporting.
  5. Provide clear contact information for security incidents and general inquiries to improve trust and compliance.

Technical notes

Notes

The website is built on a modern React and Next.js stack with Tailwind CSS for styling, indicating a contemporary and maintainable codebase. Hosting on Vercel ensures good performance and scalability. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. No CMS was detected, suggesting a custom or framework-based site. The absence of analytics or tracking scripts suggests minimal user tracking, which is positive for privacy. The technical implementation is strong but could benefit from enhanced accessibility features and security hardening.
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.
