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

10 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory
    • High

      Potential Subdomain Takeover

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

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)

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.

Business context

Business profile

Sticker Mule operates a direct-to-consumer e-commerce business model focused on custom printed physical products. Their competitive advantages include free worldwide shipping, fast turnaround, and free online proofs, which enhance customer satisfaction and reduce friction in the ordering process. The company targets a broad customer base including small businesses, designers, and DIY enthusiasts. The presence of multiple language and currency options indicates a global market reach. Their marketing ecosystem includes partnerships with advertising networks like Taboola and Bing Ads, and use of advanced analytics platforms such as Microsoft Clarity and Segment. The company maintains active social media channels to engage customers and build brand loyalty. The website content and structure support upselling and cross-selling through related tools and product categories, indicating a mature and scalable business operation.

Security posture

The website exhibits a strong security posture with HTTPS enabled and likely implementation of standard security headers. No sensitive information is exposed in the HTML content, and forms appear to be securely implemented with validation. The use of modern frameworks and libraries reduces the risk of known vulnerabilities. However, the absence of a publicly accessible security policy, incident response plan, or vulnerability disclosure program limits transparency and may impact trust among security-conscious users. No critical vulnerabilities or malware indicators were detected. The site would benefit from publishing explicit security and incident response information and establishing a vulnerability disclosure channel to enhance security maturity and compliance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and incident response procedures.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide direct security contact channels such as security@ or abuse@ email addresses.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency around data retention policies and user privacy controls to strengthen GDPR compliance.

Notes

Sticker Mule's website is built on a modern React and Next.js framework, enabling server-side rendering and fast page loads. The site integrates multiple third-party services for analytics, marketing, and video hosting, including Microsoft Clarity, Segment, Google Tag Manager, Bing Ads, Taboola, and Wistia. The design is responsive and optimized for mobile devices, with accessibility considerations evident in skip links and ARIA attributes. The site uses a custom or proprietary CMS, with no common CMS detected. Performance is optimized with asynchronous script loading and preconnect hints. The technical stack and infrastructure support scalability and a high-quality user experience. Opportunities exist to further enhance security transparency and streamline data privacy management.
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.
