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

1stDibs is a premier online marketplace specializing in luxury vintage, antique, and contemporary furniture, jewelry, art, watches, and fashion. Founded in 2000 by Michael Bruno, it connects discerning buyers with vetted professional sellers worldwide, offering global shipping and guarantees such as authenticity and money-back. The platform is well-established with a strong market position in the luxury e-commerce sector. Technically, the website employs modern web technologies including React, GraphQL, and integrates multiple analytics and marketing tools such as Google Analytics, Google Tag Manager, and Pepperjam. The site is performant, mobile-optimized, and accessible, providing an excellent user experience. Security posture is strong with HTTPS enforcement, cookie consent mechanisms, and no visible vulnerabilities, though explicit security headers and incident response policies could be more transparent. The absence of public WHOIS data reduces domain transparency but does not detract significantly from the overall trustworthiness given the professional presentation and business maturity. Strategic recommendations include enhancing security header visibility, publishing incident response contacts, and considering a security.txt file to improve vulnerability disclosure transparency.

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

4 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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"

  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

1stDibs operates as a high-end e-commerce marketplace targeting collectors, interior designers, and luxury consumers. Its competitive advantage lies in its curated selection, authenticity guarantees, and vetted seller network. Revenue streams include commissions on sales, trade programs, and possibly advertising partnerships. The company maintains a strong partnership ecosystem with payment processors and marketing affiliates. Growth indicators include continuous A/B testing and feature rollouts as seen in the extensive experimentation configurations. The company emphasizes trust and quality through guarantees and editorial content, reinforcing its market leadership in luxury vintage goods.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA, and cookie consent compliance. Security best practices such as vetted sellers and money-back guarantees enhance buyer trust. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not clearly visible in the provided data, and no public incident response or vulnerability disclosure channels were found. The lack of WHOIS transparency is a minor concern but does not indicate immediate risk. Overall, the site is secure but could improve transparency and incident readiness.

Recommendations

  1. Publish and verify security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Establish and publicize an incident response policy and security contact channels.
  3. Implement a security.txt file to facilitate vulnerability disclosures.
  4. Enhance transparency on data protection officer contact details if applicable.
  5. Continue rigorous A/B testing and monitoring to maintain technical and security excellence.

Technical notes

Notes

The website uses a modern technology stack with React for frontend rendering, GraphQL for API queries, and integrates blockchain APIs via Alchemy. It employs Google Tag Manager and Analytics for tracking, Pepperjam for affiliate marketing, and Stripe for payments. The site is well-optimized for performance and mobile devices, with preloading of fonts and responsive design. The extensive use of A/B testing indicates a data-driven approach to UX and feature deployment. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident. Overall, the technical infrastructure supports a scalable, secure, and user-friendly e-commerce experience.
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.
