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

4 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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 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 holds a strong market position as a niche publisher with a broad portfolio in biotechnology, life sciences, public health, clinical medicine, and engineering. Their competitive advantage lies in their comprehensive publishing services, including open access options and custom corporate publishing programs. Revenue streams likely include subscriptions, open access fees, and advertising. The target customer segments are academic authors, institutional librarians, advertisers, and professional societies. The company demonstrates growth through digital adoption of push notifications and advanced analytics. Partnerships with Sage Publications and compliance with industry standards like Crossref and COUNTER enhance their credibility and operational ecosystem.

Security posture

The website exhibits a mature security posture with HTTPS enabled and domain transfer protection in place. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not visibly implemented, which could be a potential area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response contact limits transparency in security governance. Cookie consent mechanisms are implemented, supporting GDPR compliance. Overall, the security maturity is good but could benefit from enhanced header policies and public security documentation.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement and publish comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack including React 17, Babel, Google Tag Manager, Facebook Pixel, and OneSignal for push notifications. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is moderately performant with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and structured data in JSON-LD format. The CMS appears to be a custom or proprietary solution tailored for publishing needs. There is room for improvement in accessibility and explicit security header implementation. Overall, the technical infrastructure supports the business goals effectively with opportunities for 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.
