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 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 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

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

IOHK operates in the blockchain technology sector, targeting developers, researchers, and blockchain community members. Their business model centers on blockchain research, product development, and community engagement, positioning them as a key player in the blockchain ecosystem. The company leverages partnerships with related blockchain projects such as Essential Cardano and Project Catalyst, enhancing their ecosystem reach. Revenue streams likely include technology services, research contracts, and community-driven initiatives. The company maintains a large organizational size and a consistent brand presence. The lack of direct contact emails or phone numbers on the main site suggests a controlled communication approach, relying on contact forms and external job application platforms. The company’s transparent WHOIS data and domain age support their legitimacy and market presence.

Security posture

The website enforces HTTPS and uses Cloudflare DNS services, providing a solid foundation for secure communications. The domain status clientTransferProhibited protects against unauthorized domain transfers. Error monitoring with Bugsnag indicates proactive operational security. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options represents areas for improvement. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, which could hinder transparency and responsiveness in case of security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be enhanced by adopting additional security best practices and publishing relevant policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies clearly accessible from the website footer or main navigation.
  3. Implement and publish security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide explicit incident response and vulnerability disclosure information, including security contact emails.
  5. Consider appointing and publishing Data Protection Officer contact details to enhance GDPR compliance and trust.

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.
