Risk levelLow

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

Sinsay operates as an international online fashion retailer targeting women, men, and children across 19 countries. The website serves as a country selection portal directing users to localized stores, emphasizing a broad European presence. The business model focuses on e-commerce retail with a user-friendly interface and clear navigation to enhance shopping experience. The brand maintains consistent visual identity and offers cookie consent mechanisms aligned with GDPR requirements. Technically, the website employs modern JavaScript libraries and third-party services such as Cookiebot for consent management, New Relic for performance monitoring, and Google Tag Manager for analytics and marketing. The site demonstrates good mobile optimization and SEO practices but lacks explicit CMS or hosting provider details. Performance is moderate with room for improvement in accessibility features. From a security perspective, the site uses HTTPS and cookie consent but lacks visible security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The absence of WHOIS data reduces domain trustworthiness, though the website content and compliance features suggest legitimate operations. Overall, the website presents a professional and trustworthy e-commerce platform with solid privacy compliance but would benefit from enhanced security transparency and contact information to improve business credibility and user trust.

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

2 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Sinsay is positioned as a large retail fashion brand with a multi-country presence, targeting general consumers interested in affordable fashion. The company leverages partnerships with major advertising platforms like Google and Facebook for marketing and retargeting. Its business model is centered on direct online sales with localized delivery options. The absence of detailed company registration or contact information on the landing page suggests a focus on streamlined user experience rather than corporate transparency at this stage. Growth indicators include multi-language support and cookie compliance reflecting awareness of regulatory environments. The partnership ecosystem includes trusted third-party marketing and analytics providers, enhancing operational efficiency.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a robust cookie consent mechanism supporting GDPR compliance. However, the lack of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options indicates potential areas for improvement. No incident response or security policy information is published, limiting transparency. No vulnerabilities or sensitive data exposures were found in the HTML content. The absence of WHOIS data raises concerns about domain registration transparency but does not directly impact site security. Overall, the security posture is adequate for an e-commerce site but could be strengthened by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and user trust.
  3. Add a terms of service page accessible from the main site to clarify user rights and obligations.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Obtain and publish verified WHOIS information or justify privacy protection to improve domain trustworthiness.

Technical notes

Notes

The website uses a modern front-end stack with asynchronous JavaScript loading, including Cookiebot for consent management, New Relic for monitoring, and Google Tag Manager for analytics and marketing. The HTML is well-structured with appropriate meta tags for SEO and viewport settings for mobile responsiveness. CSS styles are modular and tailored for different brands under the parent company. Performance is moderate, with deferred script loading improving initial render times. No CMS or backend platform is explicitly detected. The site lacks advanced accessibility features but maintains basic usability. Technical risks include missing security headers and incomplete WHOIS data, which could affect trust and security posture.
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.
