QR Code Studio is a professional SaaS platform offering advanced QR Code marketing solutions including creation, customization, real-time analytics, and collaboration features. The website is well-designed, mobile-optimized, and provides comprehensive privacy and cookie policies with consent mechanisms, reflecting a mature digital presence. Technically, it uses modern frameworks such as Bootstrap and jQuery, and integrates third-party tools like OneTrust for privacy compliance. Security posture is good with HTTPS enforced and no visible vulnerabilities, though security headers could be improved.

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

4 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. 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

The company positions itself as a leading QR Code marketing platform with a subscription-based PRO model and free trial offerings. Its competitive advantages include extensive customization options, built-in landing pages, and detailed campaign analytics. The target customers are marketing professionals and businesses aiming to enhance brand engagement through QR Codes. The website's partnership ecosystem includes related domains for marketing and privacy compliance. The business model relies on SaaS revenue streams with a focus on user-friendly design and collaboration features. Growth indicators include active marketing campaigns and a comprehensive feature set.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie consent mechanisms in place. However, no explicit security headers were detected in the HTML content, and no dedicated security or incident response pages were found. There is no visible contact information for security incidents or a vulnerability disclosure policy. The use of reputable third-party libraries reduces risk, but regular audits are recommended. Compliance with GDPR is indicated by the privacy policy and cookie consent banner. Overall, the security posture is good but could be enhanced by adding security headers and incident response information.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Conduct regular vulnerability assessments of third-party libraries and dependencies.
  4. Enhance contact information availability for customer support and security inquiries.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5, jQuery 3.6, and Parallax.js for UI effects, ensuring responsive and interactive user experience. It integrates OneTrust for cookie consent management, indicating attention to privacy compliance. Performance appears moderate with CDN usage for fonts and scripts. No CMS was detected, suggesting a custom or static site architecture. Accessibility and SEO optimizations are good based on semantic HTML and meta tags. Hosting provider details are not disclosed. Technical risks are minimal but could be mitigated by adding security headers and continuous monitoring.
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.
