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

BigCommerce is a leading SaaS ecommerce platform designed to empower merchants of all sizes—from startups to large enterprises—to build and grow their online businesses. The company positions itself as a flexible and professional-grade solution, focusing on enabling merchants to innovate and scale effectively. Their market presence is strong, supported by consistent branding and a comprehensive digital footprint including active social media channels and structured data indicating corporate legitimacy. Technically, the website leverages modern web technologies such as React and Next.js, ensuring fast performance, mobile optimization, and good accessibility. The presence of multiple marketing and analytics tools like Marketo, Segment, and Google Tag Manager indicates a mature digital marketing infrastructure. Security best practices are observed with HTTPS enforcement and appropriate security headers, although explicit security policies and incident response information are not publicly detailed. From a security perspective, the site demonstrates a solid posture with no visible vulnerabilities or exposed sensitive data. However, the absence of a public vulnerability disclosure program or security.txt file suggests room for improvement in transparency and community engagement on security matters. The WHOIS data is unavailable, which limits domain registration insights, but the overall legitimacy of the business and website is supported by consistent branding and professional content. Overall, BigCommerce presents as a trustworthy and professional ecommerce platform with strong technical and business foundations. Strategic recommendations include enhancing security transparency, publishing incident response details, and improving public disclosure of certifications and compliance to further strengthen trust and security posture.

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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 competitive ecommerce SaaS market, targeting merchants ranging from small startups to large enterprises. Their business model centers on providing a scalable, open SaaS platform that supports online store creation, management, and growth. The company benefits from a strong brand presence and a broad partner ecosystem, as evidenced by their extensive social media and marketing integrations. Revenue streams likely include subscription fees, add-ons, and professional services. The platform's flexibility and professional-grade features position BigCommerce as a preferred choice for merchants seeking robust ecommerce solutions. Growth indicators include active marketing, comprehensive content, and a focus on innovation. The company is headquartered in the United States, with a large enterprise size profile.

Security posture

The security posture of BigCommerce's website is robust, featuring HTTPS encryption and a suite of security headers that mitigate common web vulnerabilities. No exposed credentials or sensitive data were detected in the site content or scripts. The use of modern frameworks and controlled third-party integrations reduces risk exposure. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms indicates potential gaps in transparency and readiness communication. Compliance with GDPR is suggested by the presence of privacy and cookie policies with consent mechanisms. Overall, the security maturity is high but could be enhanced by formalizing and publishing security governance documents and response procedures.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to engage with security researchers.
  3. Disclose relevant security certifications and compliance attestations to strengthen credibility.
  4. Enhance contact channels for security incidents, including dedicated security or abuse email addresses.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.

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.
