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

Shift4 provides advanced restaurant management software and payment processing solutions, targeting the food and beverage industry. Their offerings include point of sale systems, contactless payments, online ordering, and cloud-based back office management, positioning them as a significant player in restaurant technology. The website reflects a professional and modern digital presence, leveraging contemporary web frameworks such as Next.js and React, and integrating multiple third-party services for analytics, accessibility, and cookie compliance. Security posture is strong with HTTPS enforced and some security best practices in place, though explicit security headers and vulnerability disclosure mechanisms are absent. The lack of WHOIS data limits domain trust verification, but the overall business credibility and website quality suggest a legitimate enterprise. Strategic recommendations include enhancing transparency with published security policies and WHOIS data, and improving privacy compliance documentation.

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 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  4. 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

Shift4 operates in the technology sector with a focus on hospitality, providing integrated POS and payment solutions to restaurants and bars. Their business model centers on software and payment processing services, targeting medium to large enterprises in the food and beverage market. The company demonstrates strong branding consistency and a clear value proposition. Their digital ecosystem includes partnerships with major analytics and advertising platforms, supporting marketing and user engagement. The absence of explicit contact information and corporate registration details on the website suggests an opportunity to improve customer trust and regulatory compliance. The company’s market position is reinforced by the use of modern technology and a comprehensive service offering tailored to hospitality businesses.

Security posture

The website employs HTTPS with a good SSL configuration, uses modern JavaScript frameworks, and includes cookie consent mechanisms, indicating a mature security posture. However, the absence of explicit security headers such as X-Frame-Options and X-Content-Type-Options, and lack of a public security policy or incident response page, represent gaps in security transparency. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The WHOIS data is missing, which is a moderate risk factor for domain legitimacy. Overall, the security maturity is good but could be improved by publishing security policies, implementing additional HTTP headers, and providing a vulnerability disclosure channel.

Recommendations

  1. Publish explicit security headers (X-Frame-Options, X-Content-Type-Options) to enhance protection against clickjacking and MIME sniffing.
  2. Provide a publicly accessible security policy and incident response contact information to improve transparency and trust.
  3. Implement and publish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance privacy compliance by publishing a comprehensive privacy policy and terms of service pages linked from the main site.
  5. Ensure WHOIS data is accurate and publicly available to improve domain registration trustworthiness.

Technical notes

Notes

The website is built using Next.js and React, indicating a modern and scalable front-end architecture. It leverages Google Fonts for typography and integrates third-party services such as Vimeo for media, Google Tag Manager and Facebook Pixel for analytics and marketing, and AudioEye for accessibility compliance. The site is mobile-optimized with good accessibility features and SEO meta tags. Performance is moderate, with multiple external scripts that may impact load times. No CMS was explicitly detected. Hosting provider details are not available from the provided data. The technical stack supports a professional user experience but could benefit from performance optimizations and enhanced security header implementation.
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.
