Security score

81/100

Risk levelLow

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

ESN operates a professional e-commerce platform specializing in nutritional supplements for bodybuilding, fitness, and health-conscious consumers primarily in Germany and other European markets. The website is built on Shopify, leveraging modern web technologies and marketing tools such as Klaviyo and Google Tag Manager to support a robust digital presence. The company actively engages in influencer marketing and offers multiple discount campaigns, indicating a mature marketing strategy and customer engagement approach. Technically, the site is well-optimized for performance, mobile responsiveness, and accessibility, with strong SEO practices and comprehensive privacy and cookie policies aligned with GDPR requirements. Security posture is strong with HTTPS enforcement and appropriate security headers, although explicit security policies and incident response contacts are not publicly disclosed. The absence of WHOIS registration data reduces domain trustworthiness from a registration perspective, but the operational website and business indicators suggest legitimacy. Strategic recommendations include enhancing transparency around security policies and incident response, and publishing vulnerability disclosure information to further strengthen trust and compliance.

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. 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 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

ESN is positioned as a key player in the European supplement e-commerce market, targeting fitness enthusiasts and bodybuilders with a wide range of protein powders, snacks, vitamins, and creatine products. The business model is direct-to-consumer online retail, supported by a multi-language website and localized market presence. Revenue streams are primarily product sales, augmented by discount campaigns and influencer partnerships. The company leverages Shopify's platform capabilities for scalability and integrates payment partners like Klarna for flexible customer payment options. Growth indicators include active marketing campaigns and a large influencer network. The partnership ecosystem includes major payment and marketing service providers, enhancing operational efficiency and customer reach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and secure form handling including CAPTCHA integration. Privacy compliance is well-managed with GDPR-aligned privacy and cookie policies and consent management via Usercentrics CMP. However, the lack of a public security policy, incident response contact information, and vulnerability disclosure mechanisms represent gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of multiple third-party scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the security maturity is strong but could benefit from enhanced public security governance documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information for security issues.
  4. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance transparency on data protection officer contact details and data retention policies.

Technical notes

Notes

The website is built on the Shopify e-commerce platform, utilizing modern JavaScript frameworks and fonts for a responsive and accessible user experience. It integrates advanced marketing and analytics tools including Klaviyo, Google Tag Manager, and Datadog RUM for performance monitoring and customer engagement. Hosting is via Shopify's CDN, ensuring fast load times and global availability. The site employs best practices in SEO, accessibility, and privacy compliance. Technical risks are minimal but include reliance on multiple third-party scripts which require vigilant security management. The absence of WHOIS data is a technical anomaly but does not impact the site's operational stability.
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.
