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

CartStack LLC operates a SaaS platform specializing in recovering abandoned shopping carts for e-commerce businesses through multichannel remarketing campaigns including email, SMS, push notifications, and on-site retention tools. The company targets online retailers seeking to increase conversion rates and recover lost revenue. The website presents a professional and consistent brand image with comprehensive service descriptions and customer testimonials, positioning CartStack as a credible player in the e-commerce marketing technology sector. Technically, the site employs a modern technology stack with multiple analytics and marketing integrations, hosted on AWS Cloudfront CDN, and optimized for mobile devices. Security posture is strong with HTTPS enforced and secure form handling, though some security headers are missing and no explicit cookie consent mechanism is present. WHOIS data is unavailable, which raises some concerns about domain transparency, but the website's professionalism and functionality mitigate immediate trust issues. Overall, CartStack demonstrates a mature digital presence with room for improvement in privacy 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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. 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

CartStack's market positioning leverages its SaaS model to serve e-commerce businesses with cart abandonment recovery solutions. Its competitive advantage lies in multichannel messaging and easy integration with major e-commerce platforms. Revenue streams likely include subscription fees for usage tiers. The target customers are online retailers and booking platforms. The company shows growth indicators through extensive marketing and integration partnerships. The ecosystem includes affiliate marketing via LeadDyno and retargeting through AdRoll and Perfect Audience. Strategic observations highlight the importance of expanding privacy compliance and enhancing direct contact transparency to strengthen customer trust.

Security posture

The website demonstrates a good security maturity level with HTTPS and secure form validation. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is indicated via privacy policy, but cookie consent mechanisms are lacking. Incident response and vulnerability disclosure information are not publicly available, which could hinder rapid response to security issues. Overall, the security posture is solid but could benefit from enhanced transparency and additional technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Add a visible cookie consent banner to comply with privacy regulations and improve user transparency.
  3. Publish a security policy and incident response contact information to enhance trust and preparedness.
  4. Consider creating a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Improve WHOIS transparency or provide domain registration details to reduce suspicion and increase legitimacy.

Technical notes

Notes

The website uses a modern and diverse technology stack including jQuery, Bootstrap Grid, Glide.js for carousels, Magnific Popup for modals, and multiple analytics and marketing tools such as Heap Analytics, Google Analytics, Facebook Pixel, and Visual Website Optimizer. Hosting is via AWS Cloudfront CDN, supporting good performance and scalability. The site is mobile optimized with responsive design and lazy loading for images. SEO is supported by proper meta tags and structured navigation. Some technical debt is indicated by multiple external scripts which may impact load times. Accessibility is basic but could be improved with ARIA roles and better keyboard navigation support. Overall, the technical infrastructure is robust but could benefit from performance tuning and enhanced accessibility.
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.
