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

KRONUS Inc. is a specialized healthcare company focused on providing immunoassay and autoimmune diagnostic test kits to medical professionals and laboratory facilities worldwide. With over 35 years of experience and an ISO 13485:2016 quality management certification, KRONUS positions itself as a trusted supplier in the niche market of endocrine and metabolic autoimmune disorder diagnostics. The website content clearly targets medical professionals and laboratories, emphasizing product quality and specialized services. Technically, the website employs a simple technology stack including jQuery 2.2.3 and custom CSS/JavaScript. The site is moderately optimized for performance and mobile devices, with good SEO practices evident in meta tags and structured navigation. However, the use of an outdated jQuery version and lack of modern security headers indicate areas for technical improvement. The hosting and domain registration are managed by reputable providers, supporting operational stability. From a security perspective, the website shows moderate maturity. The domain is secured with clientTransferProhibited status, but DNSSEC is not enabled, and no security headers were detected. There is no evidence of privacy or cookie policies, which presents compliance risks especially under GDPR. No incident response or vulnerability disclosure information is provided. Contact information is clearly available, supporting user trust and communication. Overall, KRONUS.com is a professional and trustworthy website with solid business credibility but with room for improvement in privacy compliance and security hardening. Strategic enhancements in these areas would strengthen the company’s digital trustworthiness and regulatory posture.

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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

KRONUS operates in the healthcare sector, specializing in immunoassay and autoimmune diagnostic test kits. The company targets medical professionals and laboratory facilities, leveraging a B2B business model. With a domain age dating back to 1995 and ISO 13485:2016 certification, KRONUS demonstrates long-term market presence and quality assurance. The company’s competitive advantage lies in its specialized product offerings and established reputation. Revenue streams likely derive from sales of diagnostic kits to laboratories globally. The absence of social media and limited digital marketing tools suggests a focus on direct professional relationships rather than broad consumer marketing. The company’s partnership ecosystem is not evident from the website, indicating potential opportunities for strategic alliances.

Security posture

The security posture of KRONUS.com is moderate. The domain is registered with a reputable registrar and protected against unauthorized transfers. However, the lack of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces resilience against certain attacks. The website uses an outdated JavaScript library version, which could expose it to known vulnerabilities. No privacy or cookie policies are present, indicating compliance gaps. Incident response and vulnerability disclosure mechanisms are absent, which may delay mitigation of security incidents. Overall, while no critical vulnerabilities are evident, the site would benefit from enhanced security controls and compliance documentation to reduce risk and improve trust.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and cache poisoning attacks.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website against common web attacks.
  3. Develop and publish comprehensive privacy and cookie policies to improve GDPR and global privacy compliance.
  4. Upgrade JavaScript libraries to current supported versions to mitigate known vulnerabilities.
  5. Establish an incident response contact channel and vulnerability disclosure policy to enhance security transparency and responsiveness.

Technical notes

Notes

The website uses a basic but functional technology stack centered on jQuery 2.2.3 and custom CSS/JavaScript files. The HTML structure is valid and includes appropriate meta tags for SEO and mobile responsiveness. Performance is moderate with no evident heavy resources or slow-loading elements. Mobile optimization is basic but present. Accessibility features are minimal but sufficient for general use. No CMS or advanced frameworks are detected, indicating a custom or static site approach. Hosting details are limited but the domain registrar is Network Solutions, a reputable provider. The site lacks modern security headers and uses an outdated JavaScript library, which are technical debt indicators. Overall, the technical implementation is stable but could benefit from modernization and security enhancements.
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.
