Sticker Mule is a prominent e-commerce company specializing in custom printing products such as stickers, labels, magnets, packaging, and apparel. The company targets businesses, designers, and DIY enthusiasts, offering fast turnaround, free proofs, and worldwide shipping. Their market position is strong with a well-established online presence and trusted brand reputation. Technically, the website is built on modern frameworks like Next.js and React, with good mobile optimization and performance. The security posture is solid with HTTPS and cookie consent mechanisms, though there is room for improvement in security headers and incident response transparency. Overall, the website is professional, user-friendly, and trustworthy, though the lack of WHOIS data slightly impacts domain trust verification.

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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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

      Potential Subdomain Takeover

      Subdomain mail.stickermule.com points to unregistered service elb-sta-282308608.us-east-1.elb.amazonaws.com

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

Sticker Mule operates in the competitive custom printing e-commerce sector, leveraging a direct-to-consumer model with a focus on quality and customer service. Their key services include a wide range of customizable physical products. The company benefits from a strong brand, extensive product offerings, and a global customer base. Marketing and analytics tools such as Segment and Google Tag Manager support their digital strategy. The absence of explicit contact information on the site suggests a focus on streamlined online interactions. The company appears to maintain a consistent branding strategy and offers comprehensive customer support.

Security posture

The website enforces HTTPS and provides a cookie consent banner, indicating awareness of privacy and security best practices. However, no explicit security headers were detected in the provided data, and there is no visible security policy or incident response contact information. The absence of a vulnerability disclosure or security.txt file limits transparency for security researchers. No vulnerabilities or exposed sensitive data were found in the analysis. The security score is good but could be enhanced by implementing additional headers and publishing security policies.

Recommendations

  1. Implement and publish security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance WHOIS data visibility or domain registration transparency to improve trustworthiness from a domain perspective.
  5. Maintain and regularly update privacy and cookie policies to ensure ongoing GDPR and global privacy compliance.

Technical notes

Notes

The website uses a modern tech stack including React and Next.js, enabling server-side rendering and good performance. Integration with analytics and marketing tools like Segment and Google Tag Manager is evident. The site is mobile-optimized with responsive design and accessibility considerations. No CMS was explicitly detected, suggesting a custom or headless approach. Performance appears fast with optimized assets and CDN usage. Technical risks are minimal, but the lack of security headers and incomplete WHOIS data represent areas for improvement to reduce potential attack surface and increase trust.
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.
