Risk levelMedium

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

Tosoh Bioscience operates as a specialized division of Tosoh Corporation, focusing on scientific and clinical diagnostic products. Their website presents a professional and consistent corporate image, targeting laboratories and healthcare professionals with a broad portfolio of over 500 specialty products in separations, purification, and clinical diagnostics. The site is built on ASP.NET WebForms technology, hosted with Cloudflare DNS services, and incorporates legacy JavaScript libraries alongside modern analytics tools such as Google Analytics and Google Tag Manager. While the website is accessible and well-structured, it lacks some modern security enhancements such as DNSSEC and updated JavaScript libraries, which could pose risks. Privacy and cookie policies are present with a consent mechanism, but explicit security policies and incident response contacts are absent, indicating room for improvement in compliance and transparency.

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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. 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';…

  3. 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

  4. 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

The company is positioned as a large healthcare sector player with a B2B business model supplying laboratory and clinical diagnostic equipment globally. The website references the parent company Tosoh Corporation, reinforcing corporate legitimacy. The absence of direct contact information on the homepage suggests a controlled communication channel, possibly directing users to subsidiary sites or contact forms not visible in the provided content. The site’s navigation and content focus on product portals and corporate information, supporting a professional and established market presence.

Security posture

The website enforces HTTPS and uses clientTransferProhibited status on the domain, indicating basic security hygiene. However, the use of outdated JavaScript libraries (jQuery 1.7 and jQuery UI 1.8.22) introduces potential vulnerabilities. The lack of DNSSEC and missing security headers reduces the overall security posture. No published security policy or incident response information limits transparency and preparedness perception. Google Analytics and Tag Manager are used for tracking, with a cookie consent banner implemented, showing some privacy awareness but limited GDPR compliance indicators.

Recommendations

  1. Upgrade all JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Implement and publish a comprehensive security policy and incident response contact information.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website.
  5. Enhance privacy compliance by detailing GDPR adherence and data retention policies.

Technical notes

Notes

The website is built on a legacy ASP.NET WebForms platform with a mix of older JavaScript libraries and modern analytics tools. Hosting is managed via Cloudflare DNS, but no CDN or advanced performance optimizations are evident. The site shows moderate performance and basic mobile optimization. SEO and accessibility features are present but could be improved. The technical stack indicates some technical debt and modernization opportunities, especially in front-end libraries and security configurations.
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.
