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

Herodotus is a technology company specializing in zero-knowledge infrastructure solutions for blockchain applications. Their offerings focus on enabling verifiable data, secure computation, and advanced scaling to support trust-minimized distributed applications. The website positions Herodotus as a niche player in the blockchain infrastructure space, targeting developers and organizations seeking advanced cryptographic solutions. The company demonstrates industry connections through partnerships with notable blockchain and technology firms such as Starkware and Snapshot. Technically, the website is built using Framer, with modern web technologies and Google Analytics for tracking. The site is well-designed, mobile-optimized, and provides a professional user experience. However, it lacks critical privacy and cookie policies, contact information, and security incident response details, which are important for compliance and trust. Security posture is good with HTTPS and no visible vulnerabilities, but could be improved by adding explicit security headers and vulnerability disclosure mechanisms. Overall, the website is credible and professional but would benefit from enhanced privacy 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

8 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

Herodotus operates in the technology sector, specifically focusing on blockchain zero-knowledge proof infrastructure. Their business model revolves around providing scalable and secure cryptographic infrastructure to blockchain developers and enterprises. The company leverages partnerships with established blockchain projects and technology providers to enhance credibility and market reach. The target customers are blockchain developers, startups, and enterprises requiring trust-minimized solutions. The website content and partner logos indicate a growing ecosystem and a focus on innovation in blockchain scalability and security. Revenue streams likely include infrastructure services and enterprise solutions. The company appears to be a small but specialized player with a clear niche focus.

Security posture

The website employs HTTPS with a strong SSL configuration, ensuring encrypted communication. No critical security headers were explicitly detected in the HTML, suggesting room for improvement in HTTP header security. No exposed sensitive data or vulnerable libraries were found in the scripts. The absence of privacy policies, cookie consent mechanisms, and incident response contacts indicates compliance gaps, particularly with GDPR and related regulations. The lack of a vulnerability disclosure policy or security.txt file reduces transparency for security researchers. Overall, the security posture is moderate to good but requires enhancements in compliance and transparency to meet best practices.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear contact information including security incident response channels (e.g., security@ or abuse@ emails).
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on the Framer platform, utilizing modern web standards including responsive design and SVG graphics. Google Analytics is integrated for user tracking. Hosting appears to be via Framer's infrastructure (framerusercontent.com). Performance is moderate with good mobile optimization. SEO is supported by proper meta tags and Open Graph data. However, accessibility features are basic and could be improved. No CMS other than Framer is detected. The technical stack is modern and suitable for a technology startup, but there is opportunity to improve security headers and privacy compliance to reduce technical debt and regulatory risk.
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.
