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

Byzantine Finance operates as an institutional gateway to digital assets, specializing in restaking strategies and vault deployment within the decentralized finance (DeFi) ecosystem. The company targets institutional clients, curators, and developers seeking secure, compliant, and flexible staking solutions. Their platform enables custom vault creation, restaking yield aggregation, and API-first integration, positioning them as a key player in the emerging restaking market. The website reflects a professional and modern digital presence with strong branding and multiple industry partnerships, enhancing credibility. Technically, the website is built on Webflow CMS with modern web technologies including Google Fonts, Google Tag Manager, and DotLottie animations. It is well-optimized for mobile and desktop, with fast loading times and good accessibility. Security measures include HTTPS enforcement and Google reCAPTCHA on forms, though explicit security policies and headers are not publicly documented. Privacy compliance is limited by the absence of privacy and cookie policies. The security posture is solid but could be improved by publishing formal policies, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or suspicious elements were detected. WHOIS data confirms domain legitimacy with consistent registrant information matching the business claims. Overall, Byzantine Finance presents a trustworthy and professional digital asset infrastructure platform with room for enhanced privacy and security 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

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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

Byzantine Finance is positioned as a niche institutional service provider in the digital asset and DeFi space, focusing on restaking and vault management. Their business model revolves around providing a platform for custom strategy vaults, enabling institutions and developers to deploy and manage restaking strategies with compliance and security. Revenue likely derives from platform usage, integrations, and partnerships. The company has established a strong partnership ecosystem with recognized players such as EigenLayer, Everstake, and Kiln, which supports growth and market penetration. The presence of testimonials and press coverage indicates active community and investor engagement. The company targets a sophisticated audience requiring secure and compliant staking infrastructure, differentiating itself through flexibility and API-first design.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms from spam and abuse. The platform emphasizes non-custodial asset control and claims multiple audits for its protocol, indicating a focus on security best practices. However, the absence of publicly available privacy policies, cookie consent mechanisms, terms of service, and explicit security policies limits transparency and compliance assurance. No security headers were detected in the HTML content, which could improve protection against common web attacks. Incident response and vulnerability disclosure information are not provided, which is a gap in security readiness. Overall, the security posture is good but would benefit from enhanced documentation and policy publication to meet institutional expectations.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Add a terms of service page clearly outlining user rights and obligations.
  3. Implement and publicly disclose a security policy and incident response contacts.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a modern and scalable infrastructure using Webflow CMS, which provides ease of content management and responsive design. The use of Google Fonts and DotLottie animations enhances visual appeal and user engagement. Google Tag Manager and Metricool are used for analytics and marketing tracking, indicating a data-driven approach. The site loads quickly and is optimized for mobile devices, providing a good user experience. However, the lack of explicit security headers and privacy compliance features suggests some technical debt in security and compliance areas. The contact form is protected by Google reCAPTCHA, reducing spam risk. Overall, the technical implementation is solid with opportunities for improvement in security and privacy features.
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.
