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

Loyal, operated by Cellular Longevity, Inc, is a clinical-stage veterinary medicine company focused on developing longevity drugs to help dogs live longer, healthier lives. The company is actively engaged in clinical trials and has achieved significant milestones such as FDA preliminary efficacy package completion for their senior dog longevity drug LOY-002. Their target audience includes dog owners and veterinary professionals, positioning them as an innovative player in the veterinary healthcare sector. The website reflects a professional and trustworthy brand with consistent messaging and strong media presence. Technically, the website is built on modern frameworks including React and Next.js, hosted on Vercel, and integrates analytics tools like Google Analytics, Facebook Pixel, and Umami Analytics. The site is well-optimized for performance, mobile responsiveness, and accessibility, providing an excellent user experience. SEO practices are solid with comprehensive metadata and structured data. From a security perspective, the site enforces HTTPS and employs privacy-conscious analytics configurations. However, it lacks some explicit security headers and a cookie consent mechanism, which are recommended for enhanced compliance and protection. No critical vulnerabilities or exposed sensitive data were detected. WHOIS data confirms the domain's legitimacy with a long registration history and consistent ownership. Overall, Loyal demonstrates a mature digital presence with strong business credibility and a good security posture. Strategic improvements in privacy compliance and security policy transparency would further strengthen their trustworthiness and regulatory alignment.

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

6 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

    • 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

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

Loyal operates in the veterinary healthcare industry, specializing in longevity therapeutics for dogs. Their business model revolves around drug development, clinical trials, and eventual commercialization targeting senior and large dogs. The company has established partnerships and media coverage that enhance its market visibility. Their clinical trial enrollment of 1,300 dogs across 70 veterinary clinics indicates robust operational scale and growth potential. Loyal's focus on FDA approvals and preventive care positions it competitively in a niche but growing market segment. The absence of direct contact forms suggests a controlled communication approach, likely to maintain regulatory compliance and quality control.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and anonymized IP tracking in analytics. The absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a minor gap that could be addressed to mitigate risks such as clickjacking and content injection. No incident response or security contact information is provided, which limits transparency for vulnerability reporting. The lack of a security.txt file and cookie consent mechanism indicates partial compliance with privacy regulations such as GDPR. Overall, the security posture is solid but could benefit from enhanced policy disclosures and technical header implementations.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and other privacy regulations.
  2. Add explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Provide clear incident response contact information on the website.
  5. Enable DNSSEC on the domain to improve DNS security and trust.

Technical notes

Notes

The website leverages a modern technology stack with React and Next.js frameworks, ensuring fast rendering and good SEO capabilities. Hosting on Vercel provides scalable and performant infrastructure. Integration of Google Analytics, Facebook Pixel, and Umami Analytics indicates a comprehensive approach to user behavior tracking and marketing insights. The site is mobile-optimized and accessible, with structured data enhancing search engine understanding. No legacy or vulnerable libraries were detected. The absence of a traditional CMS suggests a custom or headless approach, which can improve security and performance but requires disciplined content 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.
