Security score

Risk levelLow

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

BigCommerce is a leading enterprise ecommerce platform provider offering professional-grade, flexible solutions for businesses seeking to grow their online presence. The website demonstrates a modern technical infrastructure leveraging React and Next.js frameworks, with integrations for marketing and analytics tools such as Marketo, Segment, and Google Tag Manager. The site is well-optimized for performance and mobile responsiveness, providing a high-quality user experience. Security posture is generally strong with HTTPS enforced, though explicit security headers and published security policies are not evident in the provided data. The absence of WHOIS registration data is unusual for an enterprise-level site but does not detract significantly from the overall legitimacy given the professional presentation and strong brand presence. Strategic recommendations include enhancing privacy compliance transparency, publishing security and incident response policies, and adding security headers to improve defense in depth.

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. 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 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

BigCommerce operates in the ecommerce sector as a SaaS platform enabling businesses to create and scale online stores. The company targets business customers looking for scalable, professional ecommerce solutions. Its market position is strong, supported by a consistent brand and extensive social media presence. Revenue streams likely include subscription fees and value-added services. The platform integrates with multiple marketing and analytics tools, indicating a mature digital ecosystem. No direct parent or subsidiary relationships were identified in the provided data. The company maintains a large enterprise-scale operation with a focus on technology and business growth services.

Security posture

The website enforces HTTPS, which is a fundamental security requirement. However, no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected in the provided content, representing an area for improvement. No vulnerabilities or exposed sensitive data were identified. The lack of published security policies or incident response contact information limits transparency and readiness perception. Tracking and marketing scripts are present, but cookie consent mechanisms were not observed, which may raise privacy compliance concerns under GDPR and similar regulations. Overall, the security posture is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers such as Content Security Policy, HSTS, and X-Frame-Options to strengthen site security.
  3. Publish a security policy and incident response contact information to enhance transparency and trust.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.
  5. Consider resolving WHOIS data visibility issues to improve domain registration transparency and trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including React and Next.js, which supports server-side rendering and improved performance. Integration with marketing and analytics platforms like Marketo, Segment, and Google Tag Manager indicates a mature digital marketing infrastructure. The site is optimized for mobile devices and shows good SEO practices with proper meta tags and structured data (JSON-LD). Performance appears fast with preloading of fonts and images. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details were not available. Technical risks include missing security headers and potential privacy compliance gaps due to lack of visible cookie consent.
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.
