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

Twist Bioscience is a leading synthetic biology company specializing in innovative silicon-based DNA synthesis technologies. Their website presents a comprehensive portfolio of products including gene synthesis, oligo pools, NGS target enrichment, variant libraries, and antibody discovery services. The company targets research institutions, biotech, and pharmaceutical sectors, positioning itself as a market leader in synthetic DNA tools. The website is professionally designed with consistent branding and clear navigation, supporting multiple languages to cater to a global audience. Technically, the site is built on Drupal 10 with modern frameworks like Bootstrap and integrates numerous analytics and marketing tools such as Google Tag Manager, Segment, Marketo, and Datadog RUM. The site is mobile-optimized and accessible, with good SEO practices. Security posture is strong with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and incident response information are not publicly detailed. The WHOIS data is notably missing or unavailable, which raises some concerns about domain registration transparency. However, the website content and structured data strongly support the legitimacy of the business. No critical security vulnerabilities or privacy compliance issues were detected, and the site maintains good privacy and cookie policies aligned with GDPR. Overall, Twist Bioscience's digital presence reflects a mature, secure, and professional organization with minor areas for improvement in transparency and security disclosures.

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. 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. 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

Twist Bioscience operates in the healthcare and technology sectors, focusing on synthetic biology and DNA synthesis. Their business model is B2B, serving research and pharmaceutical clients with high-value synthetic DNA products and services. The company demonstrates strong market positioning as an innovator with proprietary silicon-based manufacturing processes. Their product ecosystem includes gene synthesis, oligo pools, NGS solutions, variant libraries, and antibody discovery, indicating diversified revenue streams. The website's multi-language support and extensive resource offerings suggest a global reach and commitment to customer education. Partnerships with companies like AtlasDS and Abveris enhance their ecosystem. The lack of WHOIS transparency is a minor risk factor but does not detract significantly from their credibility given the professional online presence.

Security posture

The website exhibits a solid security posture with HTTPS enforced and a cookie consent mechanism compliant with GDPR. Multiple third-party analytics and marketing scripts are used responsibly with consent management. However, explicit security headers such as X-Frame-Options and Content-Security-Policy are not clearly visible in the HTML, which could be improved. There is no public security policy or incident response contact information, which limits transparency in security governance. No vulnerabilities or exposed sensitive data were detected in the content. The absence of a vulnerability disclosure or security.txt page is a gap in best practices. Overall, the security maturity is good but could be enhanced by publishing more explicit security policies and incident response details.

Recommendations

  1. Publish explicit security headers like X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to strengthen browser security.
  2. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Add incident response contact information or a dedicated security contact email to improve transparency and readiness.
  4. Publish terms of service to clarify legal terms and user obligations.
  5. Regularly audit and monitor third-party scripts to minimize risk from external dependencies.

Technical notes

Notes

The website is built on a modern Drupal 10 CMS platform, leveraging Bootstrap 5 for responsive design and Dropzone.js for file uploads. It integrates a comprehensive set of analytics and marketing tools including Google Tag Manager, Segment, Marketo, Demandbase, FullStory, Datadog RUM, and social media pixels. The site is well-optimized for mobile devices and accessibility, with proper meta tags and SEO elements. Performance is moderate, likely influenced by the number of third-party scripts. The technical infrastructure supports a professional and scalable digital presence, though hosting provider details are not explicitly identified. There are opportunities to enhance security headers and streamline third-party integrations for improved performance 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.
