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

CartStack LLC operates a SaaS platform focused on recovering abandoned shopping carts and re-engaging visitors for ecommerce businesses. The company offers multichannel remarketing solutions including email reminders, push notifications, SMS reminders, and on-site retention tools. Their market position is that of an established player with integrations across major ecommerce platforms and a strong focus on conversion optimization. The website content is professional, well-structured, and targets ecommerce retailers seeking to increase sales through cart recovery. Technically, the website employs a modern technology stack with popular analytics and marketing tools such as Heap Analytics, Google Analytics, Facebook Pixel, AdRoll, and others. The site is mobile optimized and uses HTTPS with good SSL configuration. However, some security best practices like security headers and cookie consent mechanisms are missing or not detected, which could be improved to enhance compliance and security posture. From a security perspective, the site shows a mature approach with secure forms and no visible vulnerabilities or exposed sensitive data. The lack of WHOIS data for the domain is a concern and reduces trustworthiness, although the website content and branding are consistent with a legitimate business. No explicit security policies or incident response contacts are published, which could be addressed to improve transparency. Overall, CartStack presents a credible and professional online presence with room for improvement in privacy compliance and security best practices. The domain registration status should be verified further to ensure legitimacy. Strategic recommendations include implementing security headers, adding cookie consent, publishing security policies, and clarifying domain registration details.

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 targets ecommerce businesses with a SaaS model focused on cart abandonment recovery and visitor re-engagement. Their competitive advantage lies in multichannel messaging (email, SMS, push notifications) combined with on-site retention tools and integrations with major ecommerce platforms. Revenue streams likely include subscription fees for their software service. The company leverages a broad marketing ecosystem with affiliate programs and retargeting services. Customer testimonials and trust badges indicate positive market reception. The absence of WHOIS data is a potential risk factor but does not currently impact operational presence. Growth indicators include active marketing, multiple integrations, and a comprehensive feature set.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and secure form validation. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options is a gap. No incident response or security policy information is published, limiting transparency. The site uses extensive tracking and marketing scripts, which may raise privacy concerns if not properly managed. GDPR compliance is indicated by the presence of a privacy policy but lacks a cookie consent mechanism. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is moderate with opportunities for improvement in headers, policies, and privacy controls.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Verify and update WHOIS domain registration information to ensure domain legitimacy and reduce risk.
  5. Review and optimize third-party tracking scripts to balance marketing needs with user privacy and compliance.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries and analytics tools including jQuery, Bootstrap Grid, Glide.js, Heap Analytics, Google Analytics, Facebook Pixel, and others. The site is mobile responsive and has good SEO metadata including descriptive titles and keywords. Performance is moderate with asynchronous loading of many scripts. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident. The site could benefit from improved accessibility features and enhanced security headers. Overall, the technical infrastructure supports a professional ecommerce SaaS offering with some areas for modernization 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.
