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

Nutrisense is a healthcare-focused company specializing in personalized metabolic health insights through continuous glucose monitoring (CGM) technology combined with expert dietitian coaching. The company targets individuals seeking sustainable health improvements such as weight loss, energy enhancement, and better metabolic control. Their business model is subscription-based, offering CGM sensor deliveries and 1:1 coaching, with some services covered by insurance. The website reflects a mature digital presence with a strong brand, extensive member testimonials, and trust signals like high Trustpilot ratings. Technically, the website leverages modern web technologies including React, Webflow CMS, and AWS Cloudfront for hosting and content delivery. It integrates multiple marketing and analytics tools such as Klaviyo, TikTok Pixel, Facebook Pixel, Microsoft Clarity, and Google Tag Manager, indicating a sophisticated approach to user engagement and data-driven marketing. The site is well-optimized for mobile and accessibility, with fast performance and good SEO practices. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms compliant with GDPR. While explicit security headers are not fully confirmed in the provided data, the use of reputable third-party services and absence of exposed sensitive data suggest a solid security posture. However, the lack of publicly available incident response or security policy documents is a gap. The WHOIS data is unavailable due to a malformed request, limiting domain trust verification, but the overall site professionalism and branding support legitimacy. Overall, Nutrisense presents a trustworthy and professional online presence with strong business credibility and technical maturity. Strategic recommendations include enhancing public security disclosures, verifying and publishing security headers, and improving WHOIS transparency to bolster domain 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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Nutrisense operates in the personalized healthcare sector, focusing on metabolic health through CGM technology and dietitian coaching. Their competitive advantage lies in combining real-time glucose data with expert coaching, supported by insurance coverage for many users. The subscription model with monthly biosensor deliveries and coaching sessions creates recurring revenue streams. The target market includes health-conscious individuals, those with metabolic concerns, and people seeking sustainable lifestyle changes. The company has a significant member base (150,000+), indicating strong market traction. Partnerships with insurance providers and integration with existing CGM sensors expand their ecosystem. The website's extensive testimonials and certifications enhance credibility and support customer acquisition.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent management, and use of trusted third-party analytics and marketing tools. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Security headers presence is assumed but not confirmed, and regular audits of third-party scripts are recommended. Compliance with GDPR is supported by the privacy policy and cookie banner. Overall, the security posture is solid but could benefit from enhanced documentation and public disclosures.

Recommendations

  1. Publish a detailed security policy and incident response plan accessible on the website.
  2. Verify and implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate supply chain risks.
  4. Improve WHOIS transparency by ensuring accurate and accessible domain registration information.
  5. Enhance user trust by providing a vulnerability disclosure program or security.txt file.

The website is built using modern web technologies including React and Webflow CMS, hosted on AWS Cloudfront CDN for fast global delivery.

Performance is fast, supported by CDN usage and deferred script loading. The technical stack supports scalability and user engagement but requires ongoing maintenance to manage third-party dependencies and security.
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.
